I suspect that @Sfor's main problem is that his Primetime Content Decryption Module isn't working as it should be on Firefox 52 ESR. The sites which have a problem are I suspect ones which use HTML5 video and no longer have a working Flash fallback system, so they are just throwing up errors when HTML5 fails.

The problem is with the MSO.DLL file. The updates which replace this file are now replacing it with a version that is not compatible with Windows XP. The last compatible version is 14.0.7214.5000, which is date stamped 14th September 2018, and was included in KB4092483. All later versions will not work, and there is no solution to this I'm afraid. Microsoft have been told about this, but not surprisingly have not done anything about it. I'm sure their line now is that none of their software is now supported on Windows XP, even if it was originally.

Welcome to the forum! I got the update fine on the Windows 10 side of my machine, but I have the 64 bit version of Office 2010 installed there, with the 32 bit version on XP. Maybe it doesn't like installing a 32 bit update on a 64 bit OS, but if that's the case I'm surprised this hasn't happened before. Even if no error message appears when you try to install the update, is there anything in the Windows Event Logs?

Is YouTube using Flash or HTML5? You can easily tell by right clicking on a video window and seeing what pops up.

Don't reset your existing profile, just make a temporary new clean one. You can easily revert back to your previous one when you've finished testing. The necessary dialogue is under "about:profiles". The site you mention seems to work absolutely fine here in FF 52.9. In fact the videos don't seem to be using Flash at all, they are using HTML5 video, which is what I would now expect. There's no evidence here that it's loading the Flash plugin at all.

Certainly recent versions of Firefox only support the NPAPI Flash plugin, and no others (the latest version 69 will no longer allow you to set it to always activate) but Firefox 52.9 ESR certainly has full NPAPI plugin support, I have over 60 of them registered! I would suggest that you try this with a temporary new clean Firefox profile, as corruption somewhere in the profile is the most likely cause of this issue. Do you have an example of a site showing the problem just so I can make sure that it isn't happening on my system as well?!

Sorry if I'm asking the obvious, but you have got the latest version of the plugin I assume (32.0.0.255), and it is set to "Always Activate" in the settings?

What Flash problems were you having with 52 ESR? It all seems to be working fine for me.

Well it's perfectly possible that I didn't run the file checker after the previous Office update, so those Excel files could have been updated by that, not by the latest one! They do have the same file version as the new ACECORE.DLL though, if that's relevant.

Strange, Custom User Agent String should work with any Firefox version above 48. Have you tried one of the older versions?

As far as I can see from my system file checker, the files updated were ACECORE.DLL (Microsoft Access database engine DLL), EXCEL.EXE, and EXCELCNV.EXE. All are now version 14.0.7237.5000. Why an update apparently for Outlook should update Excel files I have no idea!

I couldn't agree more, a very generous gesture, which will I hope ensure that Rudolph will never be forgotten by the DOS and Windows 98 preservation community. I have four of his programs, and I will happily provide them if they prove to be missing from the proposed archive.

It would certainly be a great shame if Rudolph's work now became permanently unobtainable. We don't know the circumstances of his death of course, but if he knew enough in advance what was going to happen, he may well have taken steps to preserve his program archive and make it available in the future as part of his legacy. We can only hope that he did have a chance to do that.

Wasn't sure which section to put this in, but here's as good as anywhere. I can't vouch for the accuracy of the information, but it's quite hypnotic to watch! https://www.youtube.com/watch?v=eJuvKn5j_kE

So shocked to hear this, it was only a month or so ago that I was corresponding with Rudolph about a disk partition alignment program that he had just built. I use several of his programs, to enhance my Windows 98 installation, and to do things like applying TRIM to my FAT32 SSD. He was an absolute genius, up with the very top experts on this forum IMO. 67 is no age to go nowadays. RIP Rudolph.

Of course there is now an iPhone 11, but the argument is certainly valid with desktop OSX and Windows 10, which I suspect will be with us for the foreseeable future!

I agree about the ridiculous version numbering nowadays, but I certainly hope Mozilla's ship isn't actually sinking! That would be a great tragedy, and an indication that effectively Google Chrome and Edge (also now soon to be Chromium based of course) have finally permanently won the "browser war", and will permanently control all of the web's browsing technologies. I'm sure you're right about "rapid release cycles" being all about "looking good". In the "old days" a "version 10" for instance, would last for years, going to 10.1, 10,2, etc., with sub-increments even between them. Nowadays there would probably be more than 20 full version increments where before the main version number would have only changed once!

I changed the screen in my Asus netbook as it was fitted with a highly reflective one which was like looking in a mirror! The matt finish one I replaced it with is much better. It wasn't too difficult to do, but obviously this varies a lot between different units. Its native resolution is 1024x600, which means that Windows 8.1 apps will not open as they have to have at least 768 vertical resolution to work. I used a registry hack to enable me to switch the resolution to 1024x768 to use the apps, but in this mode the display is not only blurry, but also compressed vertically so everything is distorted. That is preferable IMO to the image being the right shape but vertically cropped! This is tolerable for temporary use to read the mail or news app, but hardly ideal, and is a good example of the undesirability of using any display at anything other than its native resolution.

What is the native resolution of the display fitted in the laptop? Usually, displays only look at their best at their native resolution, so trying to go higher may actually produce poorer looking results.

Thank you again! And yes, point taken. Cheers, Dave.

Yes, I've noticed that as well. Not so much of an issue as there aren't that many of them, but it would be good to get them working if it's possible.

Thank you so much @mixit, it's now working fine again. I will keep your user agent string on Instagram just for hopefully some future proofing in case they start completely rejecting older Firefox versions, although it was almost certainly just my sloppy attempt to modify the userCustom.css code that was the problem, nothing to do with the user agent! Cheers, Dave.

Thanks @mixit! I now have this in userContent.css @-moz-document domain(instagram.com) { div._97aPb [role="dialog"] { display: block !important; } } How strange to have a trailing space in the div name! I had tried that div name before and it didn't work, but maybe it needs a different user agent string now as well, which it didn't before. I've tried several, and none of them make it work again. Could you tell me what user agent string you're actually using? Thanks, Dave.

I've tried using custom user agent strings on Instagram, which I've not done before, and all that seems to happen then is that the page won't load at all, just showing a blank white page with a camera icon in the middle of it!

Thanks. I've been trying to tweak @mixit's code to bring it back, but no luck so far. He did say that it might well break if they changed their "div" names. I guess we were lucky that it worked for as long as it did!
