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?

Please view screen captures that best show the random issues I have with Firefox browser. This started a few months ago on my desk top PC. I have kept my Firefox up to date using 147.0.1. and still run WIN 10 Home. Although I am sure Linux is in my future!

The issue happens randomly where the top row of my browser disappears off my screen. I can work around the issue no problem but would like to know and understand the issue and if I can resolve it from happening. Firefox is the only app I have this issue with. And it is random and cannot be forced, I have tried....

Thank you for help. John Montani

Hi,

When I type map into address bar, maps.app.goo.gl becomes the autofill. I'd want to delete it. However, shift-delete does not take effect. I checked history and did not find it.

How can I delete it?

Thanks

Hello, I have installed the latest Firefox on my Windows 11 desktop PC. I have created a shortcut to Firefox in the start menue Since a few week, I observed that I had to invoce Firefox twice in order to get is running once. The same happens if I double-click on firefox.exe in the intallation folder (C:\Program Files\Mozilla Firefox): After the first double-click, the windows activity circle appears for a few seconds and then dissapears again (without staring Firefox). After the second double-click, Firefox starts immediately.

I can repeat this several times.

• first double click > nothing happens
• second double click > Firefox starts
• closing Firefox
• third double click > nothing happens
• fourth double click > Firefox starts
• closing Firefox
• fifth/seventh/... double click > nothing happens
• sixth/eigth/.. double click > Firefox starts

I have no idea what might have gone wrong. Any suggestion from the community is appreciated. Best,

After installing update 147.0, when watching videos on YouTube or twitch, artifacts appear on the monitor and an error message appears stating that your driver has been restored to its default value. In version Firefox 146.0. There were no such problems, and in general there were no such problems. But my graphics card is not a new AMD Radeon R7 250X 1gb. Version 147.0 states that "Improved video playback performance on systems with AMD GPUs by enabling zero-copy playback for hardware-decoded video where supported, bringing them to parity with Intel and NVIDIA GPUs." I think the reason here is the incompatibility of either drivers or with encoding support on old video cards, I hope that the developers will fix this problem for me.

The welcome addition of Tab Groups I just noticed on updating my Firefox, however looking through help and documentation, it's not clear to me if Tab Groups syncrhonise across devices (or at least desktop devices) as like recently added to Chrome. Wished to check if this is case

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.

Hello, I just completed a wipe of my whole device, beforehand I obviously signed up and synced up my Firefox account to keep my boomarks and data. After reinstalling Firefox I managed to sign in, sync up and get my bookmarks back - great. However after reopening of the app they were gone again and when checking back-ups the only available one was from after the "automatic wipe". I quickly checked my mobile Firefox app as well - it still showed a bigger of number of bookmarks so I had hoped they stayed at least there but after entering the folder they appeared empty and then gone completely after re-entering. Please if possible assist, it seems like Firefox decided to overwrite this data so maybe it's still somehow recoverable as these bookmarks have been collected over the years. Thank you in advance.

When I opened a new Firefox page it contained links to more or less interesting articles in newspapers. For some reason I had to reset Firefox, now everything works fine again. But the links to articles are gone and I have no idea how to get them back. Any hints?

Whenever I try to access the Powerball website I get the following response -

The request is blocked. 20260116T144515Z-17584c64c9f58vrnhC1MIAm1t80000000t4g00000000rcec

I have no issue with other browsers.

Thanks Gary

For the last couple of days, the address bar on the web apps that I've installed to my taskbar has been shrunk to about a third its usual length. I don't have flexible space put anywhere on my toolbar, and the problem is only on the sites I've put in the taskbar, not in regular browser windows. Is there a way to fix it, and get it back so it reaches all the way to the extension icons?

I'm using Firefox 147.0.1 on Windows 11, Version 25H2, Build 26200.7623, if that helps
