Firefox Community Forum

Hello, My Mozilla browser has been displaying new websites in black and white for two years or more (NYT, SMH, NZ Herald, Gdn - see screenshot attached). Substack, random theatre co, Airlines, conferences etc etc everything else appears in colour!

I am not great on tech so I have looked at Settings and asked google and got nowhere. Thanks people for any advice - It will be appreciated.

(PS seriously Mozilla help please do not offer those asking for help a manual troubleshooter link without stating it will wipe their help request when they use it. This is just mean of you).

Sometimes, when I try to watch a youtube video, it will not play and sometimes while the video plays, it suddenly turns green and my RAM usage climbs to 100% I cannot refresh the page and have to restart Firefox, but it can still happen again. My graphics drivers are also up to date, so I'm not sure what the issue is.

Hi, Re Firefox browser how do you get back 2 windows with tabs that disappeared when restarting the PC. They are not in history anymore at all, they are gone. What opened up instead after the restart, was 2 lots of Windows & tabs that just disappeared in the same way, from 3 years ago, & they reappeared on the browsers. Can you tell me what is going on please & how to fix this problem in losing them in the first place? This problem has happened several times before & is very upsetting. Can you help in finding my recent loss of windows/tabs please? Regards Doug

Firefox keeps randomly crashing and won't open, sometimes I can get 10 minutes before it returns to crashing all over again. Doesn't even OPEN troubleshoot mode, it just auto crashes.

My drivers are up to date, my windows are up to date, Firefox is up to date, Internet Security software is up to date.

I need this running ASAP for work, each crash report has a different code too which hurts.

First crash happened in the afternoon, yesterday. bp-6580ff2f-d79c-4472-89f6-542c60250604 4/06/2025, 5:15 pm

I am unable to receive emails into my Gmail inbox using a normal window. I can send mail but not receive it. I am using a laptop with windows 11. I can use gmail both in and out in a private window. I can use it in Chrome and Edge. It's only Firefox. I've been sending test messages from my Proton account to my gmail account I've disabled all the addons for mail.google.com I don't know anything about pop/imap but I think it must be Firefox settings I've cleared the cache I've tried to sync everything but that only sync between tablet phone and laptop I've asked google for help and gone through the lists including a config check I've closed Firefox and restarted I've restarted my laptop I thought I'd use Private windows and set it all up, signed in on my tabs, saved them to a folder and arranged to start in private using the tabs in that folder but then I had to sign in to everything again when it started. Signing in to Google is a pain in the arse as it is to sign in to X I've spent 6 hours so far...... I've used FF for years, the easy answer is to use Edge but I don't like it that much Please help.

bold text It is not possible to watch videos in 1080p since the moment I installed the latest update. I have to reduce to 720 or 480 to get smooth motion. Running Windows 10. How can I fix this?

Im using vertical tabs and whenever I create a new window by shift clicking on the taskbar icon to create a new window theyre hidden by default which is really annoying. I tried looking through the settings and I have both "Hide tabs and sidebar" and "Expand sidebar on hover" unchecked. Is there a flag I can set somewhere to force it to be visible in new windows?

Im using Windows 10 (10.0.19045 Build 19045) with Firefox 139.0.1

Thanks

After using Firefox 138.0.4 64-bit (most recent version) for a few hours I get this kind of glitch on my taskbar preview in Windows 11. Please see the image. It especially happens when I unsleep the computer and leave Firefox running I think. I have already tried a refresh and reinstall. Now I'm trying to run firefox with no extensions/addons in safe mode. If that doesn't work I'm going to start thinking something is wrong with Windows 11. Was there something in about:config I shouldn't have touched involving multiple processes? (I think that resets with a reinstall/refresh anyway) Anyone know how to make this go back to normal? I can reboot to fix it or restart explorer.exe in task manager but it comes back like this in a few hours of useage.

I'm sure I don't have anything else open. If I hover mouse over the blank "windows" I don't get any kind of tooltip and nothing changes but an X does appear. I can click it and nothing happens. Right and left clicking these windows does nothing. When I close Firefox they still remain. I closed Firefox and Firefox isn't running in the task manager anywhere, yet the blank windows remain.

I have no idea what just happened. I went to log off a website and a notification popped up that said "Check browser's developer console". I searched here for "developer console" and there were 0 results. I did log off after the 2nd try so it's no big deal but I'm just wondering what that notification meant. It sounds kind of serious. What did it mean? Thanks!

Windows 11/Firefox/Google

Firstly, my apologies, but I only have a very basic understanding of computers.

I somehow ended up fiddling with a side bar on the right hand side of my screen, and the next thing I knew I had lost the ability to have multiple tabs open on my screen. I tried google a solution and came up with this:

"View>Cusomise toolbar in browers. Look for the new tab button. If its there, drag it back to the toolbar, typically to the right of the existing tab."

I tried that, but it didn't work. The plus sigh came out on the left rather than the right of my search bar, and every time I clicked it I just got a new page, rather than a new tab being added to the existing one.

I would be grateful if anyone has a solution to this issue.

This warning appears on so many pages since up the Firefox update that it's making it difficult to actually use Firefox. And your suggestion "To see this page, you need to open it in a new window", doesn't work. Clicking option + the link doesn't offer a chance to open a new tab or new window. And the block is still there when I copy and paste the desired link. Two of the biggest issues are on highly reputable sites (a bank and a telecom). I suggest you fix this "upgrade" because other browsers don't have this problem.

For the better part of a year now I have to reinstall FireFox almost daily. It just stops opening tabs. I get a tab crashed error and the only way to get it to navigate to websites is to shut down FF and reopen it. Then at least half the time when I shut it down I get a new error that this is an old version of FF and I have to create a new profile. I'm not interested in creating a new profile. I've had this one for years and years. So then I have to use Chrome to download the FF installer again and reinstall to get it to work. I really prefer FF but it's almost unusable at this point. What is going on at Mozilla that their browser no longer works on Windows 10 or 11?

Abandonment of Pocket is pushing me back to use of my Firefox Bookmarks Tree.

After a long period of maintenance on my Firefox Bookmarks Folders within the "Bookmarks Menu" I accidentally moved a folder named "Music" into some other folder. I've checked the folders which contain nested folders which are near to where the "Music" Folder should be but cannot find the "Music" folder.

It seems that Firefox Browser ver. 39.0.1 (aarch64) on my M4 MAX MacBook Pro 16" running macOS Sequoia 15.5 makes it easy to search for and to find a bookmark, but not its location within the folder structure in which the bookmark is located. I need to see that folder location so that I can move the folder "Music" back to the top level within the "Bookmarks Menu."

What facility is provided by Firefox for me to perform this search?

I've been using Firefox since Windows first came out and NEVER had this problem (or any other) until about a month ago. After an update, my bookmarks sidebar failed to work. I tried to update again, but got the message "Secure Connection Failed". After many tries, I was able to load a 32 bit ( V 1390.1) which was offered from Mozilla. This despite the fact that my PC is a 64 bit machine. This 32 bit version works poorly! I've repeatedly tried to load a 64 bit version, hoping that it would work as Firefox has in the past. I am still getting the the message "Secure Connection Failed", Error Code Mozilla_pkix_error_key_pinning_failure. What is going on??? I like Firefox and I'm reluctant to change browsers, but it may become necessary. Operating systwm: windows 10. Bob N

Sequoia 15.5 Firefox 139.0.1

Firefox recently enforced an update. After this update, I can no longer open file browser for attachments if a website offers this option (example: this very form, Browse... button does nothing). I can also not Save to PDF any more. In both instances, a spinning wheel will appear and then nothing will occur.
