How can I remove the moving blue ball from the tab of a frequently used website? It's distracting and hopefully not symptomatic of a problem It appeared on this new computer/monitor, used to be an icon Thanks, --Laurie

I don't understand the problem. My accessing Firefox has become limited. I received a note to Upgrad to windows 11... I hae already upgraded. What must I do too have it recognised?

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

This has worked for me for years. It just began a few days ago when I tried to login and look at my new auto insurance policy. I've cleared the cache/cookies to no avail. I can access the web site with Edge (yuk)

This is a brand new problem, for me. It just started today when using FireFox. On nearly all websites, including Mozilla support, when I click on an embedded link on a site, firefox asks me to select an app to open the https. Even if I tell it to let firefox open all https, it still asks me everytime. to make it better, it still doesn't always let me open the link and I go through the same thing when I click the link again.

This also happens when clicking on the search box in *any* search engine, e.g. Google, Startpage

See the image below.

I've attempted to change all cookie & tracking settings, no help. I even uninstalled and reinstalled Firefox.

This is making FireFox useless.

I had to use my default browser, Brave, just to submit this question. I only use FireFox for social media accounts, sites I need to link to my sm accounts and the occasional web search. For example, linking my Etsy shop to facebook. When I clicked the link "link to facebook" is when I noticed this problem.

Not sure if this is the correct topic, but I have been using Firefox for over 20 years, and after the last update, there is an icon missing from my Firefox browser page. It's the "file" icon in the very upper left corner of the window that allows "new tab", "new window", etc. I'm still using windows10, on an ASUS PC, but never had the problem until just recently. I've restarted the computer, reloaded the window, nothing works to restore that icon/function. Thanks - Mike B

You took my $65.72 image attached!! I have no Mozilla and you can't seem to email 6 didget varifacation code to my proton e mail address. Send the code to [edited phone# from public community support forum]. Thank you

I have changed operating systems from windows to linux mint. I made sure to sync my profile before uninstalling, but now the profile looks to be empty. there are no saved passwords or bookmarks. This worked when I changed between different windows devices last year, but this time it seems stuck. I will check on a windows device when able, but in the meantime, are there any other ways to troubleshoot this?

When I try to make a Google search I get the following message, "I'm not a robot" with a reCAPTCHA: "Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?". This happens on Firefox, but not Chrome or Edge. If I 'Allow' Google in the 'Exceptions - Cookies and Site Data' then I do not get the message, but it takes several seconds for Google display the resulting page. However, if I delete the cookies/cache the message will return and I have to redo the reCAPTCHA. I have scanned with Malwarebytes, Bitdefender, Hitman Pro, Trend Micro House Call and Microsoft Defender, nothing detected. Running Win 10 (64) with 'Extended Security Updates', Firefox 147.0 (64), no additional Extensions or Plugins. Also I uninstalled and reinstalled Firefox.

Since latest upgrade (1/16/2026) I cannot log in to Outlook email. This is specific to Firefox 147.0.1 (Chrome and Pop Peeper logins to Outlook work fine). I tried clearing cache, updating, restarting, rebooting, trouble-shooting mode, private window etc. to no avail. I get 400 error from Outlook.

In Firefox, I have several windows open, each with many tabs. (And BTW, I love the Firefox tab-organization feature.) I would like to empty the cache and delete all cookies. Will that close the open tabs? Is there a way to delete the cookies, empty the cache and preserve all windows & tabs?

      Thank you!

My address bar disappeared. I can get it back by hitting F10 but it doesn't stay. How can I get it back and keep it? When I go to the Customize Toolbar setting, the address bar is not there.

Why all of a sudden I cannot reacht my saved passwords anymore. Also it does nit prefill the saved passwords anymore when going to a website. How come Firefox/Mozilla keeps changing these essential things?? It makes it very much so less productive.

I've included a screenshot of what I get when clikcing on the Password tab. The information displayed in this wcreen also does not work. Clicking on Sync, does just nothing, just showing Sync in grey... Clicking on Login above just show this screen screen again. Useless.

Followed unstall and trying to remove remaining folders, data from computer.

I cannot del these folders, etc despite being admin mode or from command line.

whats next.

I want to do a fresh install of Firefox but wont install firefox again if I have to an computer reimage.

When I watch videos (reels) on Facebook, and sometimes on YouTube, I share a video either to messenger or my page, the whole string of videos I have already watched goes back to the beginning of the string everytime. Only Firefox does this. I have 3 other browsers that work fine, but I prefer Firefox of course.

I'd appreciate a fix for this, Thanks
