Can't restore previous session, "recently closed windows" grayed out

Hi

I had two Firefox windows open. One with 100+ tabs and the other with 1 tab. I closed the Firefox with 100 tabs, and then closed the one with 1 tab, without thinking. I then realised that I should have closed them in the opposite order, because I want the 100 tabs to get restored.

I opened Firefox again and was dismayed to see just the single tab get restored. I did some searching and backed up the "sessionstore-backups" folder.

I then tried to close Firefox and replace sessionstore.jsonlz4 with previous.jsonlz4 from the backed up "sessionstore-backups" folder. This did not work, as when I opened Firefox I still only got the 1 tab back and "recently closed windows" remains grayed out. Ctrl+Shift+N does nothing as well.

I used https://www.jeffersonscher.com/ffu/scrounger.html to inspect the backed up previous.jsonlz4 file and it shows

Open Windows Open Window 1 Tab 1 [...]

Closed Windows Closed Window 1 Tab 1 [...] [...] Tab 125 [...]

So the previous.jsonlz4 file does contain my mistakenly closed window but I can't get Firefox to restore the tabs!

Can anyone please help me get my tabs back? I'm on Firefox v96.0.1.

WebGL has stopped working. I think this has happened with Firefox 91.

For example, http://webglsamples.org/aquarium/aquarium.html gives the error Status: WebGL creation failed: * tryNativeGL () * Exhausted GL driver options. (FEATURE_FAILURE_WEBGL_EXHAUSTED_DRIVERS)

I'm running Firefox on Debian on ChromeOS.

On about:support, WebGL 1 Driver Renderer: Red Hat -- virgl WebGL 2 Driver Rendered: Red Hat -- virgl

There are no WebGL errors in about:support

I've tried the Troubleshoot Mode but that made no difference.

Hello,

I noticed that a setting on the about:config page was removed: the "security.csp.enable" setting. I was using this setting to disable CSP to be able to load local JS scripts on some non-locally hosted sites, for debugging and development, work related purposes.

Was this setting really removed? Is there a way to disable CSP on Firefox on the latest version?

Thanks! Gabriel.

I just turned off AdBlock Plus in the Add-Ons screen and downloaded ublock origin to try it out. There is no icon for this new plug in to be found anywhere. I can manually go in and change the settings on this plugin in the add-ons screen but there is no icon anywhere to go in quicker or to show a report of how many items were blocked. When I try to Customize my toolbars, the icon is not available there either. The nearest threads I can find on this topic are from 2018 and their solutions are very basic use. Yes, of course I restarted the browser. TIA.

I have a Win7 machine, and just bought a new Win10 desktop. I followed some instructions from a YouTube solution. From the Help>Troubleshoot>Profile Folder, I copied the profile folder (onto an external drive) and pasted it (from the external drive) onto the new OS(C:) as per instructions.

It did not work, I do not have all my bookmarks and extensions, etc. on the new Firefox browser I have installed on my new machine.

I don't know what to do now. All that was selected and overwritten is still selected on "This PC>OS(C:)" I was tempted to just delete all that shows selected...maybe not a good idea.

I really just wanted to migrate all my bookmarks, but doing the full profile folder seemed like a good idea at the time.... Help Mr. Wizard?!!

In most standard Windows applications, the title bar and tab colour follows the default Windows settings, e.g. (in my case) the title bar and tab colour of active application windows is blue. This is true even in Thunderbird. Since FF 89, title bar and tabs are something between white and light gray, which is extremely user-un-friendly. FF developer team should return to the previous colour scheme. Yes, I know the circumstances of free software but this is NO excuse to alienate millions of users. Developers that change fully functionable software just, well, just to CHANGE it should consider that they are doing WRONG. Could anyone tell them? I am just user, not developer and I am not willing to learn developer tools like BugZilla just for this simple guiding principle.

It seems like something has changed recently, I don't remember having such problem before. As you can see on one of my pictures I have browser settings changed to always ask what to do with every file extension, yet encountering link to pdf file it loaded automaticly in special frame instead of showing just link to it. I included pictures of this frame, settings and another screenshot of the same website in Opera browser with similar settings where nothing loads itself.

Link to the problematic comment with auto-loading pdf: https://kodluch.wordpress.com/2021/09/30/30-09-2021-syria-2187-dzien-sprzatania-swiata/#comment-115906

Is there any way to block such pdf-frames in current version of Firefox?

What is the last Firefox version that works with MAC Lion OS X 10.7.5?

I have a study program of that vintage that plugs into firefox and the version on the computer now is 3.0.10 (from year 2009 and the program does not work with it.

The program is compatible with Lion OS X 10.7.5 but the Firefox version is too old.

The version 3.0.10 on the computer does not work well with most sites or crashes. The intent is not to expect to browse, just be new enough for this program for its dedicated use.

I'm running Firefox 99.0.1 on Ubuntu 22.04. Recently (I think since I updated to Ubuntu 22.04 about a week ago), Firefox has been refusing to show me file upload dialogs. When I click a button that's supposed to give me one, nothing happens.

This has been happening with: - The "attach files" button in Gmail - A file upload button on Gradescope (website for managing homework assignments) - File -> Open File... and Ctrl+O.

Dragging and dropping a file onto an email in Gmail does attach the file -- it's just that the button doesn't work.

I've tried restarting, and I've tried running Firefox in Troubleshoot Mode -- so far nothing has fixed the problem. What else should I do?

Hello, I'm not sure if I chose the right topic above.

I'm trying to visit a site which is still using http. But Firefox is automatically redirecting to https, where of course it cannot resolve the site.

In settings, I have it set for "Don’t enable HTTPS-Only Mode". But still, Ff is redirecting.

I don't know. Maybe I should set for https only, and then enter an exception??

I have searched for a solution, but for every solution I find, when I look up how to do it, it says, before you try this, try that first. After about 5 rounds of that, I got too confused and gave up.

Oh, I also cleared the cache, but no help.

I've enabled all the extra info below. But let me know if you need any other specific info. Do you need the address of the website?

Thank you very much.

Hi, I am using the dark mode in firefox which is god sent boon to persons having glaucoma, with dark mode in firefox and dark reader add on. This was going well and after a recent update, I could not find it working. The dark mode is enabled and dark reader was there, but the browsing pages only shows in white. Has firefox changed anything recently to have this issue? If I miss something would the experts say, how to get back my dark browsing experience in all sites. If I find anything not visible in some sites, I used to go the windows properties and change the contrast theme to windows basic blue theme and then switched back to dark theme. this was helping the glaucoma persons very much. please, say how to solve this problem

The BBC website believes I am in another country, other than the UK. It currently redirects from bbc.co.uk to bbc.com, with some content no longer being available.

I have checked my IP, and it is currently a UK-based IP address. I do not have any active VPN profiles.

I have refreshed Firefox, deleted profiles, and redownloded but still the issue presists.

This problem is not reflective on any other browsers on the same machine.

Grateful for your help.

This is the BBC's advice, which I have followed - https://www.bbc.co.uk/contact/questions/behind-the-scenes/website-domain-change

I got a new computer recently and it was already upgraded to windows 11. I downloaded Firefox because it is my main go-to. It worked for a few days then all the sudden, it just stopped loading, if I tried to search something it would just load forever and never show up. Even dev tools would not display, it just was like in a frozen state, I tried downloading the Developer version of the browser, nope! Deleting all program files, Nope! Then when I tried to use edge, smooth as can be. What the heck is going on here?
