@Radish does this include 52.9.0 ESR as I get not compatible with quantum yet mine isnt a quantun just regular normal 52.9 download This add-on is not compatible with your version of Firefox.

I'm not sure why it refuses to let me connect to sync using 66, but reverting to 52 it does

@Dave-H what I should off said correct addy to use in useragent to get into the Firefox Sync to connect i did try general.useragent.override.about:preferences#sync Mozilla/5.0 (Windows NT 6.2; rv:66.0) Gecko/20100101 Firefox/66.0 i just get a spinnig blue circle, No go unless i revert to 52

anyone have any idea with FF 52.9 what the correct add is to put into the useragent as if I use this general.useragent.override Mozilla/5.0 (Windows NT 6.2; rv:66.0) Gecko/20100101 Firefox/66.0 i just get a spinnig blue circle i can't get into it But if I change it to Mozilla/5.0 (Windows NT 6.2; rv:52.0) Gecko/20100101 Firefox/52.0 it does let me in

Has anyone tried extracting the cert8.db file from a firefox install, I tried to with 7zip, but couldn't find it anywhere in any of the folders (Unless it is created on a install), was hoping to, to see if there is/was a way of updating SSL certificates that are out of date or due to expire or soon will do i'vr noticed there is quite a few out of date or due to be

Since doing the nessecary cert update and other things to get extentions working, now when I restart FF, I have 2-3 addons that keeps wanting to ask permissison to install, yet before this it Never asked, how can I get round this so they stick permenant and don't keep asking too Should I change the extenrion.json file back from read only what I set it to,

I Got hit on 52.9.0 & 52.6.0 doing the change cert to false from true and -1 to 2 worked, what I posted a few posts up is more permanent to 2020 and DOES actually work, its a certificate update . . I wonder IF it;s a possibilty to get lastest FF (which is been fixed) install open with 7zip and extrat the cert8 file and use that in older browsers ??

Well I hope there is a fix for this debarcle or we are screwed seems we can't go No higher 53 is for Win 7 and above

Damn apart from what I am using 52.9.0 i have a 52.9.1 installer, but doubt if there is hardly any difference

Using Win XP SP3

This actually works on XP SP3 does it I downloaded, Firefox Setup 60.6.2esr but hesitant to install

seems to be working now althogh sketchy at times

@Dave-H It seems to be fixed now. A certificate had expired apparently, which presumably nobody at Mozilla had anticipated! I didn't have the problem with FF 52.9.1 ESR on Windows XP, but I did have it on FF 66.0.3 on Windows 10. It was very annoying while it lasted! it hit me on 52.9.0 around 7.30pm is there a fix for ESR thought it was only Nightly at the moment, ESR will be last ===================== Try this, this DOES work I have done it with success, unlike other so called fixes Shut down Firefox Open extensions.json Rreplace all instances of "appDisabled":true to "appDisabled":false Replace all instances of "signedState":-1 to "signedState":2 Save Change extensions.json to readonly or firefox will change everything back. start browser Disable and re-enable all extensions in about:addon some will have Delete icon missing most Will re-install and delete icon comes back Make sure you set yhe json file to read only then any that stil get not verified use the about:debugging and reload the extention

Had a bit of a head scratcher this morning I copied my prefs.js from one PC to another PC, started FF couldn't work out why Youtube and Instagram was broken, all the strings were correct, then realised i needed the other 2 .js files and it worked.................................. This one I don;t understand I have all the files C:\Documents and Settings\All Users\DRM on both PC's all the folders/files gmp-eme-adobe gmp-gmpopenh264 gmp-widevinecdm in right places on both PC's have silverlight installed on both yet Netflix WILL play on one PC but NOT other can;t fathom this out I Get Opps something went wrong Digital Rights Management (DRM) Error Am I missing something or maybe file Both PC's ARE Win XP SP3 I did try a boolean set to true media.windows-media-foundation.enabled nope IF Like has been mentioned xp doesn;t support DRM, how is one XP PC I have playing Netflix yet the other doesn;t I Have ALL the correct strings booleans in bot PC;s ALL the right files in right place there MUST Be something in one not in the other Silverlight is on both does Netflix fall back to HTML5 A SIde Note I did find this 2019 Firefox will disable the Flash plugin by default. Users will not be prompted to enable Flash, but it will still be possible to activate Flash on certain sites using browser settings. 2020 In early 2020, Flash support will be completely removed from consumer versions of Firefox. The Firefox Extended Support Release (ESR) will continue to support for Flash until the end of 2020. 2021 When Ahttps://www.bleepingcomputer.com/news/software/mozilla-to-disable-flash-plugin-by-default-in-firefox-69/dobe stops shipping security updates for Flash at the end of 2020, Firefox will refuse to load the plugin. this here almost almost does it a few seconds then goes to ooop https://addons.mozilla.org/en-US/firefox/addon/force-1080p-netflix/

thnx @Mathwiz you sir are a saint I did this and changed main useragent back to general.useragent.override;Mozilla/5.0 (Windows NT 6.1; rv:66.0) Gecko/20100101 Firefox/66.0 and it worked a treat thank you

it hasn't No, it used to i have gone thru the about:config, still playing Side one here another silly one was I was getting flagged with red wavy line for a incorrect spelling, so i was adding to dictionary then realized i can turn of spell check

Can someone help me please When Firefox crashes it doesn't restore my previous tabs open it , used to (wait a few seconds) , till i had to a fresh install when it crashed and I reopened FF the restore box would come up, it doesn't anymore. Even a normal close with FF set to remember my browse and tabs it doesnt it is greyed out and No history even thought it is set to I have sessionstore-backups folder with 2 files in there is no file(s) sessionstore.js Recovery.js.Recovery.bak Previous.js sessionstore.bak sessionstore.bak in profile folder I have closed FF & reopened, still no tabs & greyed out "Restore Previous Session". I closed FF again is there any files I need or amendments to about config thnx EDIT..................

Javascript is capable of detecting your browser- without using the above info seems java script can still read what you have and send,,,, maybe this is why I can't use Netflix if I say I have different So, set the following: general.XXX.override where XXX is the name of the specific object code you want to set. For example, on my system javascript:navigator.platform is "win32", so to change this, I'd create a new string: general.platform.override and set it to "Linux i686".

It appear the Netflix does alot deeper sniffing if i have general.useragent.override;Mozilla/5.0 (Windows NT 6.2; rv:66.0) Gecko/20100101 Firefox/66.0 having above set then general.useragent.override.netflix.com/gb;Mozilla/5.0 (Windows NT 5.1; rv:50.0) Gecko/20100101 Firefox/50.0 I get Netflix system requirements for HTML5 Player and Silverlight You can use our HTML5 player or the Silverlight plug-in to watch Netflix TV shows and movies on PCs running Windows XP or later, and Intel-based Macs running OS X Tiger (v10.4.11) or later. You'll find a complete list of requirements below for HTML5, Silverlight 4, and Silverlight 5. HTML5 Silverlight 4 Silverlight 5 there is this Operating Systems and Browsers Operating System Internet Explorer 11 Internet Explorer 10 Internet Explorer 9 Internet Explorer 8 Internet Explorer 7 Firefox 12-52 Safari 4-11 Chrome 12-44 NOTE Firefox versions only upto 52 but setting general.useragent.override;Mozilla/5.0 (Windows NT 6.2; rv:66.0) Gecko/20100101 Firefox/66.0 back to general.useragent.override;Mozilla/5.0 (Windows NT 6.2; rv:52.0) Gecko/20100101 Firefox/52.0 Netflix will allow me to play videos So it apears with Netflix there is deeper sniffing as I do have Silverlight 5.1 and sure I have HTML5 even tho it didnt fall back to it even with all the gmp strings in place and have Primetime Decryption in aswell I've noticed (unless I'm wrong) that reporting a browserabove 62 breaks Youtbe.com I'm sure it used to work reporting 66 also where I had No sidebar on utube there is now one also about:sync breaks aswell unless it is set to 52 what would be the override prefrence for this

@VistaLover @Mathwiz thank you for your patience and understanding it is appreciated very much, must of had a mind block (which sometimes happens tales a while for somethings to sink in) overload of info, . the old saying can;t see woods for the trees . I literally unpicked everything and broke it down and went thru everythin bit by bit and low n behold it now works having general.useragent.override;Mozilla/5.0 (Windows NT 6.1; rv:66.0) Gecko/20100101 Firefox/66.0 (as the main one) then general.useragent.override.instagram.com;Mozilla/5.0 (Windows NT 6.1; rv:56.0) Gecko/20100101 Firefox/56.0 instagram now indeed works and not get broken i'm trying a few other websites that either sniff or breaks due to browser version being sent is wrong. . I can say creating a new (user set string) general.oscpu.override (Value) Windows NT 6.1 does indeed send your OS as (Window 7) instead of 5.1 (XP) going here http://useragentstring.com and herehttp://browserspy.dk/os.php I may play with these general.appname.override - (user set string) Netscape sends the name of browser general.appversion.override - (user set string) 5.0 (Windows) not sure general.buildID.override - (user set string) 0 browser build general.platform.override - (user set string) Win32 says wether is is 32 or 64 bit general.productSub.override - (user set string) 20100101 this says when the browser was built might have a further play to fool about:support to fool it i have latest stuff fool it it is a newer browser, and build, so 20130621 is 21st june what the others is unsure 064021 more so the OS version instead of telling me its Windows_ NT 5.1 instead 6.1 i would belive the build ID is when it was builr unless about support reads from the PC and not browser then a no go Once again thank you to all who helped get this in his skull Now this interesting https://www.whatismybrowser.com/guides/the-latest-version/firefox according to this there is Firefox Extended Support Release 60.6.1 yet I can't get my FF to update (which appears to be for Windows 7 (32 bit),Windows 7 (64 bit),Windows 8,windows 10,Mac OS X,Linux this is only a passing thought, I used to play with hex editors years ago changing a program say from a trial or shareware install to a full install or changing a program to say it was diffrent wonder it this is possible to do with FF fool they system you have a new version

Right I went right back to begining undoing what I did the config files and recreated the config-prefs.js and config files with correct script in each putting in correct folders made sure there was No double entries in the Prefs file restarted FF went to about :config it was clear, then tried to create a new string general.useragent.override.whatismybrowser.com; but this still came back and set as user set and not as default (as shown in someone else's image i did notice a few posts back there is this Components.utils.import('resource://gre/modules/UserAgentOverrides.jsm').UserAgentOverrides.init(); which is different to another post // needs to start with a comment line Components.utils.import("resource://gre/modules/Services.jsm"); Services.obs.addObserver(function (aSubject, aTopic, aData) { var chromeWindow = aSubject; chromeWindow.setTimeout(function () { Components.utils.import("resource://gre/modules/UserAgentOverrides.jsm", chromeWindow); chromeWindow.UserAgentOverrides.init(); }, 1000); }, "browser-delayed-startup-finished", false); so which of those 2 js is right I have done No other mods to prefs apart from the media and gmp strings/booloeans ot to make addons/extenrions appear I Did come across these -------------------------------------------------------------------- general.appname.override - (user set string) Netscape general.appversion.override - (user set string) 5.0 (Windows) general.buildID.override - (user set string) 0 general.oscpu.override - (user set string) Windows NT 6.1 "(Possible ro sppof your OS)" general.platform.override - (user set string) Win32 general.productSub.override = 20100101 general.appversion.override = 5.0 (Windows) general.oscpu.override = Windows NT 6.1 general.platform.override = Win32 general.buildID.override = 20100101 it appears these are hidden so will not appear in a search in about:config -------------------------------------------------------------------------- to further spoof I would presume this one general.oscpu.override - (user set string) Windows NT 6.1 will spoof your OS None of these are present in FF If you visit here http://browserspy.dk/ this site will reveal just how much sniffing there is and what can be seen by sites ================================================== On trying a new string general.oscpu.override;Windows NT 6.1 then going here http://browserspy.dk/os.php it does indeed spoof your OS version, tried it with and without and got 5.1 and 6.1

I musr still be missing something, as I followerd guide and created a file config-prefs.js with pref("general.config.obscure_value", 0); pref("general.config.filename", "config.js"); and placed in the C:\Program Files\Mozilla Firefox\defaults\pref then a config.js with // needs to start with a comment line Components.utils.import("resource://gre/modules/Services.jsm"); Services.obs.addObserver(function (aSubject, aTopic, aData) { var chromeWindow = aSubject; chromeWindow.setTimeout(function () { Components.utils.import("resource://gre/modules/UserAgentOverrides.jsm", chromeWindow); chromeWindow.UserAgentOverrides.init(); }, 1000); }, "browser-delayed-startup-finished", false); placed inside C:\Program Files\Mozilla Firefox But when i try to create a UA string it is still set as user set instead of default i tried putting useragent.override.whatismybrowser.com;Mozilla/5.0 (Windows NT 6.1; rv66.0) Gecko/20100101 Firefox/66.0 inside the file config-prefs.js but alto it appears in about:config straig away with out manually putting in, it still show as user set NOT as default I have checked for any "possible" mistakes I "may" have made I have made correct files in right places, have I missed something should any mods be made to C:\Documents and Settings\Administrator\Application Data\Mozilla\Firefox\Profiles\q65xjekw.default-1556195193171 there isn't any of other files mention in both my ff folders usually i am ok in picking up, but maybe a numpty here lol is ther ea sting or boolean I need to amend from true to false or vice verse to force from bevoming user set to default ?

I'm still not sure where to do the ssauo's is it in the about: config or in one of the config files i created and put in the relevant folders . if i have this set to general.useragent.override;Mozilla/5.0 (Windows NT 6.1; rv:67.0) Gecko/20100101 Firefox/67.0 i can get to alot of sites but some if not a few get broken you cant reach unless its a lower version, i encountered this earlier regardless of browser version or OS verssion stated. if I do general.useragent.override;Mozilla/5.0 (Windows NT 6.1; rv:53.0) Gecko/20100101 Firefox/53.0 i can get to most but odd one no go but if i if I do general.useragent.override;Mozilla/5.0 (Windows NT 6.1; rv:53.0) Gecko/20100101 Firefox/53.0 in the main one then a new string as general.useragent.override.whatismybrowser;Mozilla/5.0 (Windows NT 6.1; rv66.0) Gecko/20100101 Firefox/66.0 still reportss as out of date then as another string so there is 2 i have a few general.useragent.override set to 67, can't figure this out i'm sure i followed guide properly doing the 2 txt files and put in right folders this what shows

how do you set the Status to default instead of user set in Firefox I;ve noticed if you have this general.useragent.override Mozilla/5.0 (Windows NT 6.1; WOW64; rv:66.0) Gecko/20100101 Firefox/66.0 it breaks this https://accounts.firefox.com/settings you can't get to it same as instagram but setting back to Mozilla/5.0 (Windows NT 6.1; WOW64; rv:53.0) Gecko/20100101 Firefox/53.0 you can get to your firefox settings account .if I set browser to 53 then do this general.useragent.override.whatismybrowser;Mozilla/5.0 (Windows NT 6.1; WOW64; rv:66.0) Gecko/20100101 Firefox/66.0 it still reports as out of date what am i doing wrong
