Firefox keeps crashing and Hanging and I get the error message "gah your tab etc" I have followed the advice for fixing the problem but it keeps coming back Its really annoying when you are trying to do something I'm no computer whiz and I have looked at the crash reports, its just gobble gook to me, I need help to fix the problem.

I had an issue with the hidden task bar not showing up when I moved my cuser to the bottom of the screen, so I was "playing around" and messed it up. I created another profile, but lost all my bookmarks and so forth. I copied files from my old profile to the new profile, but now I can't get to michaels.com - it won't load. Also, I have my yahoo mail tab looks like it's loading, but I got in my email and when I went to blackforrest.com it does the same thing.

I still have the issue of my task bar not "unhidding" when I go to the bottom of the screen. I have to minimize my screens to see the task bar.

Can you help, please?

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).

I host services on my local network like: miniflux.thepromised.lan and usually accessed them by going to the short hostname directly like: http://miniflux and it just worked great until a few Firefox releases ago. I don't know when it stopped working but I can't get firefox to use my local DNS servers on my own wifi to resolve these local addresses.

My current workaround is to connect to my local vpn and force all traffic that way. No other app on my android device has this issue. Chrome works exactly as expected. I can also open a live dashboard to my pihole instance and watch in real time for dns queries that come over the wire. I can't get firefox to use these local servers at all.

What am I doing wrong?

Thanks!

Once I visit any web site that uses HTTPS there is approximately a 90% chance it'll take seconds or even minutes to secure the connection. This never happens on other browsers as they load such pages instantaneously.

I already cleaned my data up and removed the extensions, both suspected and innocent bystanders, to no avail.

As stated in the title, I'm using Firefox 139.0.1 x64 on Windows 11 (24H2, build 26100.4061). This started happening after an automatic Firefox update, I never changed anything in my system configuration.

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.

In the last few months I noticed that I could not completely connect to Facebook on Mozilla on my desktop, I could access from my phone and other web browsers though. I tried clearing cookies, cache, etc. without improvement and just gave up. Now I'm beginning to have issues with other sites not loading completely or at all (Amazon, Yahoo, gmail). I again have tried clearing cache/cookies but its not helping. Just like with Facebook previously, I can access Amazon, Yahoo, gmail, etc on other web browsers from my desktop; just not on Mozilla.

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?

  I have worked with ATT and it is not on their end,the issue is only when trying to sign in to my account. I have tried uninstalling Firefox and doing a new install and issue is still there. Have done all the usual steps such as clearing cache, cookies etc. I can access on my cell phone, just not when using Firefox. This just started in the past 48 hours

Hi, I have been using Lightning Calendar for as long as I can remember. As part of an ongoing personal data security task, after having my online account hacked, I recently I moved my Calendar Data from the GMX servers to my Synology NAS, Using Caldav I can synchronise data between my Android Phone & my PC, keeping all my data private. It has been working fine for a few months so I move my Wifes calendar data over as well, and that worked great as well. However, I have now come up with a problem, sometimes if I edit an event in on my PC any changes made will not save, however, if I make changes on either my Android Phone or through my browser they do.

So, I think this is possibly an issue with Thunderbird, any suggestions please.

Note. My address book syncs and can be edited on all devices.

I've notice keyboard issues with certain sites.

Using PayPal, Firefox will not enter the sixth digit of a confirmation code. The first five numbers will enter in the boxes, the sixth momentarily enters but doesn't persist. It works on Chrome, so it's not a PC issue.

Today I was trying to enter my full name in a text field. I couldn't enter a space between my first and middle names. I tried 'Troubleshooting Mode' and it still didn't work. I could enter the details in Chrome, though.

The PayPal issue have persisted over several updates.

I'm using Firefox on Kubuntu 25.04.

Hi, Can I? How? Thanks
