In Firefox 114.0.2, the tab foreground color for most NYTimes.com pages initially is black, but after an instant, the foreground color now becomes gray. The background color is a similar gray, so the tab symbol for the NYTimes (beginning with an ornate letter T) cannot be distinguished from the background. The NYTimes tab foreground color used to remain black.

For an example, go to https://www.nytimes.com/. The tab foreground colors for some NYTimes pages remain black; for example, go to https://help.nytimes.com/hc/en-us. I think this tab foreground color change began recently, less than a month ago. This problem does not occur for web sites other than the NYTimes. Restarting my computer does not help. This tab color problem does not occur in Edge or Chrome.

Thanks for any info

Firefox crashes whenever I paste something in search bar. Even if its one word only. It has been like 3 months now and no help. It even crashes in troubleshooting mode. I have reinstalled and refreshed, but it helped only for a day.

Thanks in advance.

After updating to Firefox 115.0-1, I noticed that the tab names for all inactive tabs automatically greys out whenever the main Firefox window loses focus (see attached gif image). Only the system theme is affected. I should also note that only Firefox 115 exhibits this behavior (downgrading to Firefox 114.0.2-1 fixes the issue).

I'm not sure if this is by design. I've gone through the change log for Firefox 115 and found no mentions of this.

Of course, the behavior isn't that big of a deal. However, since I'm using a window manager (i3wm), an annoying "flash" (see attached gif image) can be observed every time I press a keybinding to activate a binding mode.

If this is a new feature, I'd very much like to turn it off in about:config.

Does anyone know how?

Within the last hour or so, I needed to close Firefox while installing an app (the setup was recommending to close all Windows programs).

Had 8 windows open.

Right-clicked on the Taskbar Firefox icon, then selected the option "close all windows" - it proceeds to close each window consecutively, asking me each time for manual confirmation whether to close this window with x tabs in it - and I just confirm each time.

So then after that setup is completed, I open Firefox again - the last closed window is restored (as per the settings);

then I click on History, "recently closed windows", and.... there's only 2 windows on that list. I restore those 2, and then the list is empty - nothing more to restore.

So if I had restarted the PC, it would've just restored the 8 windows upon reopening Firefox, as usual - but since I opted to just close Firefox like this, "close all windows", I just lost 5 windows.

So could anything be done here?

Something in the files? Maybe the C:\Users[user]\AppData\Roaming\Mozilla\Firefox\Profiles\4qu1kfr9.default-release\sessionstore-backups path? There's a file called "previous.jsonlz4" in there, something I could do with that one?

Or something else?

Any help would be appreciated!

Hi, not sure what I'm doing wrong, but my logins and passwords simply will not synch between devices. I principally use a desktop Win10 machine, and an iOS version of Firefox. Have double-checked settings on both devices, tried forcing a manual sync from each to the other, all to no avail. Any ideas on what I need to do differently? TIA.

Windows keyboard shortcuts: In any window one can press Alt+Spacebar, which gives a little menu of options for the window as a whole: Restore, Move, Size, Minimise, Maximise, Close. The menu does appear (if one does this in a Firefox window), and one can use the arrow keys to go to the function that one wants and execute it, but there should also be shortcut keys R M S N X and C. These shortcut keys always used to work in Firefox but they stopped working a few versions ago: sorry I didn't immediately take a note of exactly when this happened, I just assumed "that will be sorted out soon" but it hasn't been. It's not exactly a problem, but I like being able to close a window by Alt+Spacebar, C  : that takes a fraction of a second, while moving the mouse to close the window by getting the pointer in the right position to click on that X (top right) is considerably slower. OK I can retrain myself to do Alt+spacebar, up-arrow, return, but even that is 1 extra key.

I am using Windows 10 22H2, reasonably up to date: but this window behaviour has been standard in Windows for a very long time.

Something changed in my privacy settings in one of the recent Firefox updates - I did not intentionally change anything. Now I get frequent messages along the lines of "Sorry. Because of its privacy settings, this video cannot be played here." I tried clicking on the shield to turn Enhanced Tracking Protection off but that does not change all the privacy error messages I get. The "Settings" menu and options are so complicated that I cannot figure out a setting that allows access to these videos, even trying to "manage exceptions."

So I am lost and frustrated and have to continually switch to another browser to view these things - it is getting to the point that it makes no sense for me to keep having to go to another browser and I am considering stopping using Firefox, which I hate doing because I have always loved Firefox.

This is a last ditch effort to help me continue using Firefox - I would love to get this issue resolvedd, if anyone can assist and advise.

My computer 'guru' reinstalled Win10 in order to correct a serious problem. ALL of my programs were gone and I was left with a raw Win10. 6/12/2023 was last date prior to the disaster. I reinstalled Firefox. Using the "firefox.exe -p" I can only find the default profile. I DO HAVE a full backup done using the Win7 Backup and Restore feature. How do I resurrect my most recent profile? I will need to find the files(s) manually from the b/u. When I did a Full Restore the bookmarks didn't appear. Where and what files am I looking for? The attached screen shots from the b/u may be of help. [removed email from public forum]

On Google Docs, the very useful shortcut "Alt+/" for executing menu actions by name exists, similar M-x in Emacs or Ctrl+Shift+A in PyCharm or Ctrl+Shift+P in VS Code.

On a German keyboard, there is no "/" key. In Chrome the hotkey "Alt+#" works instead. In Firefox, it does not.

This hotkey is particularly important, because it gives quick access to menu actions, that have no hotkey assigned, or for which the hotkey does not work on the current layout.

Is there something I can do to make it work?

Note. Based on what I know, I cannot tell if this is an issue with Firefox not sending the Alt+# key correctly, a special feature of Chrome that isn't present in Firefox, or a cross-browser compatibility issue of Google Docs, that should be blamed on Google Docs and not Firefox.

Firefox 114.0.2 (64-bit), running on Open Suse 15.3, 64 bit.

When I click a mailto link it brings up the GMail app. Instead I want the Yahoo Compose window. Several posts suggest various arcane methods. Either they do not apply or they require hacking. Has the situation improved?

How can I make mailto links go to the Compose window on mail.yahoo.com?

Hi there! I am a long time Chrome user and decided to try Mozilla Firefox. I loved it and after a bit of tweaking, I run into a problem I can't deal with myself. In Chrome I loved auto fill options every time I needed the option for my home address, email address or credit card. In Firefox I just can't do it. The option is only available for Canada or SUA. Is there any way I can make it work? Of course, I looked for some add-ons and actually found several, but given the fact that auto-fill in my case deals with personal and sensitive data, I need a safer method. Is there any? Thank you!

I installed what I thought was the "trust wallet" extension. It's not the real trust wallet. I had a little over $5K stolen in BTC, ETH, and SOL. Is there any way you can help me catch the individuals or somehow get back my stolen funds? Or any advice or direction will be helpful.

Firefox 114 introduced hidden support for nvidia video super resolution. In about:config you can enable preference gfx.webrender.super-resolution.nvidia to make it work. However I see 0 difference on all videos on all pages. I have everything in nvidia control panel set correctly (VSR enabled and set to 4/4 quality).

Tried to find more info online and someone on reddit complained that it worked before but it stopped working with latest firefox beta (probably before final 114 release): https://www.reddit.com/r/firefox/comments/13duluz/nvidia_video_super_resolution_comes_to_firefox/

I tried using logic too - if this pref is related to webrenderer in its name maybe it is not working because I am not using webrenderer? However I checked about:support and in section graphics->composition I have "webrenderer" so it seems I am using it, but its VSR feature is not working at all.
