On my system, I'm successfully using

general.useragent.override.addons.basilisk-browser.org;Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:68.0) Gecko/20100101 Goanna/4.8 Firefox/68.0 Basilisk/52.9.2021.07.19

NB that official Bk is a 64-bit only release on Windows 7+... :sneaky:

Catastrophes in youtube mobile and desktop mode

Catastrophes in youtube mobile and desktop mode

It used to happen to me in sp52 with no multiprocess. I have for the last few months switched to multiprocess, and unnecessarily script-bloated sites (like YT) run now smoothly. See

and the first post in that thread, by @Mathwiz, and discussion thereafter. Many extensions fail to work, but you can deal with those issues (for example, for visiting github/gitlab) running a separate profile with no multiprocess.

Hi there. Has anyone tried this (compared to mailnews)? In particular: can IceDove-UXP(mail) be run with lower rights?

Can you upload your prefs file

Hi @kwisomialbert. I use the following settings in user.js, but automatic functionality is mostly broken. When the item is commented with // auto means that it works automatically (in my set up); // set means that you need to open and edit in auto:config; // add means you need to create the setting in auto:config (aka, hidden setting -boolean for true false, string otherwise); // default means it is the default value (in my set up). Be aware that the settings are fit to my usage, and will likely break many sites/functions I do not care for, meaning, use at your own risk. The list includes settings mostly derived from user.js for FF52-9 and FF53, plus some provided by users here, such as @VistaLover, @XPerceniol, @Sampei.Nihira, @Mathwiz and others. Hope it helps.

Is anyone having problems on Twitter with the volume slider and UXP 52 and 55? It seems to have just started but it will no longer pop up to adjust the volume. Still working in the newer firefox versions.

Hi @kwisomialbert. I use the following settings in user.js, but automatic functionality is mostly broken. When the item is commented with // auto means that it works automatically (in my set up); // set means that you need to open and edit in auto:config; // add means you need to create the setting in auto:config (aka, hidden setting -boolean for true false, string otherwise); // default means it is the default value (in my set up). Be aware that the settings are fit to my usage, and will likely break many sites/functions I do not care for, meaning, use at your own risk. The list includes settings mostly derived from user.js for FF52-9 and FF53, plus some provided by users here, such as @VistaLover, @XPerceniol, @Sampei.Nihira, @Mathwiz and others. Hope it helps.

imgur is just getting worse. now its unusable. no changes on my end

**dmiranda** · September 12, 2021

Ha ha. I never heard of imgur before these posts. I tried to follow the nest of multiple scripts, xhr, frames and whatnots in ublock, ematrix and noscript in sp52, to no avail. It works fine in any of @Humming Owl or @Articfoxies's V12 or V13 360chrome mods, though. So there you have it.

I've been using 360 more lately as FF is struggling nowadays.

True for heavily scripted pages. These I run in 360. But for "normal" browsing I prefer sp52.
