Форум поддержки Firefox

here is the video: https://streamable.com/zffknq the issue is about transparent bar with vertical addons and slowly fullscreen animation, and the fullscreen animation isn't config-able, I already set full-screen-api.transition-duration.enter 0 0 full-screen-api.transition-duration.leave 0 0 in about:config, and disable sidebar or userChrome is not work too. and this is happend about one mouth ago after my nixos update firefox.

Firefox losing all of my session history is an inevitability. I have encountered this problem on many cases over the past decade, be it due to an update, a power failure, a BSOD, or just randomly (despite closing the application correctly); like a law of nature, eventually firefox will just forget to open a window, or the entire session. This issue has caused me to switch to other web browsers in the past, multiple times. They each struggle with this in their own way.

Sometimes I can save my session by finding it in the sessionstore-backups folder, but the problem I am talking about is that that does not always work! Often times the backups get overwritten when the problem occurs - even if I don't touch firefox or open it again or close it, even if I immediately notice that a window that was there when I previously opened firefox is no longer there, often times nothing in the backup files actually has the version that I want. It's always overwritten with the new/modified session that's missing hundreds or thousands or tabs from my session restore history.

I think that the ability to actually restore a session and not have to cross my fingers that it doesnt blow up and delete my entire history (which randomly occurs at least once every few months) is the biggest problem with firefox. It is the most frustrating thing that any web browser can do. And quite frankly even if I wanted to use Firefox Sync to store my session information on a remote server (which I do not!) I do not actually trust that firefox will actually not fumble it and randomly delete my session every few months, given the history of how this problem has existed as long as I have been using this software. At least with the local sessions, sometimes I can recover some of the data, which isn't an option when firefox sync inevitably drops my session history. I am on the verge of setting up some kind of recurring task to back up the session store files on a regular basis just so I don't go crazy.

So: why does this problem exist? Is there a long running thread about why the session restore system sucks? Will it ever get fixed (even having multiple backups or the ability to manually save a backup in the UI would be a major improvement)? Are there community supported tools to fix this problem by saving extra copies of the sessionstore files?

Hi,

Yesterday I set up a new computer, installed Firefox and logged in to my Firefox account. Everything went well, my bookmarks appears, all (!) my extensions were installed, everything looked fine. Then I went about my way configuring unrelated Linux stuff, using Firefox as normal on both computers, no problems.

But at some point, I suddenly noticed that on both computers, the icons for most of my extensions had disappeared. And sure enough, looking in about:addons, all that was left were five addons (Dark Reader, Simple Translate, uBlock Origin, Dictionary Anywhere, OneTab). And on both computers, including my main laptop (!), where I hadn't done anything other than clicking around in websites.

And it only affected the extensions, my bookmarks, history, etc all is fine and synced between the computers.

No restarting of Firefox, choosing different profiles in about:profiles (there was only one other, a mostly empty one), nothing got them back. And looking in ~/.mozilla/firefox/, sure enough extensions.json and all extension related folders had been changed, looking as if I never had more than these five extensions installed.

And when I installed one of my usual extensions again, all of it's settings and customizations were back to default. So this is not just a case of having to reinstall a few extensions. All custom uBlock filters, all Tampermonkey scripts, etc, everything is gone.

I tried looking around on the web for solutions, but it appears that there is no one who has had this exact issue before, and I couldn't find any indication that there is any way to revert such an error by Firefox Sync.

To my luck, I have a secondary laptop where I should have a mostly up-to-date instance of my Firefox profile, from which I will now try to recover my extension data, but if that weren't the case, years of fine-tuned settings and customizations would be gone.

As people rely on Firefox Sync to back up their Firefox data, instead of backing up their Firefox data "against" Firefox Sync failing like this, I'd think this is not something that ever should be possible to happen. At the very least, there should be some way to revert errors like this. Perhaps Firefox Sync could store backups either server side or client side before syncing deletions like this?

This has been a problem for a while, currently on Firefox 126.0 and Nvidia 550.78. I can work around the problem by forcing webrender to use software mode.

When using HW accelerated webrender with my Nvidia graphics card everything works fine until the PC wakes from sleep, then graphics are broken and Firefox needs restarting. Most noticeable for me is when looking at Grafana graphs they will look like random lines, and my Frigate NVR snapshots only display some of the time.

Is there anywhere in Firefox that will show a log of any error messages to do with the graphics card? I would like to try and fix the problem rather than disabling HW acceleration, but with no logs to look at that is impossible. No other programs seem to have a problem with resuming from sleep, and no error messages are shown in any of the system logs.

This pops up every few hours. Sometimes it pops up invisible but steals focus from the main window. How can this be disabled?

I tried all methods that have been mentioned everywhere on the Internet, including policy.json, Group Policy on Windows, etc. Nothing disables this nagging yet.
