Firefox 社群討論區

The Vanguard website warns me that my Firefox browser "is no longer supported" and must be updated. when I try to update, the message is "Firefox is being updated by another instance." what does "another instance" mean? how can I update it? fyi I run Windows 11 on my desktop.

Hi there.

The original problem is described here: https://support.mozilla.org/en-US/questions/1472503 ( Also the solution I found.)

Jaws and James seem to have left the building.

This problem first occurred with the update from V 135.0.1 to V 136.0 . Currently on V 136.0.4, and every update has exhibited the same behavior.

I have the same issue with two laptops, running Windows 10. Each has been through a few update cycles, and the "Restart to Update" always fails.

So, I close FF, watch for the Resource Monitor to quiet down, and reopen FF.

When I go through this sequence, I notice that the screen will flash once VERY quickly before opening the home page.

FF seems to function normally otherwise.

Thanks for being there,

I "create a new profile" days ago what I first received the notice to update. It seem to work except when I click on a url to view. I received instead the notice that I am in the old firefox and to "Update". I did again and it seem to work until I clicked a url to view and again received a notice to "update by creating a profile.

It's very frustrating - Now I can't open firefox at all. It wants me to "fix it" or create a new profile"

Hello, I'm having some problems with updating firefox. It started a few months ago that I got a Pop-up every time I started Firefox about needing to update it. But when I click on the prompt to update it, it leads me to this website: https://www.mozilla.org/de/firefox/new/?reason=manual-update , and after clicking on the download button I get to this site for about a second: https://www.mozilla.org/de/firefox/download/thanks/ after which it loads this site: https://download.mozilla.org/?product=firefox-stub&os=win&lang=de which my browser can't connect to (aka just gives me the standard error message as if you entered an invalid URL). Today I got this website pop-up when starting Firefox: https://www.mozilla.org/de/firefox/welcome/21/ which leads to the same outcome as above. After that I tried to update Firefox by going to the menu -> help -> about Firefox, which searches for updates but then tells me that I have the newest version installed already??? Even when I try to manually install a new version through this site: https://www.mozilla.org/de/firefox/all/ I still get the same result. Please somebody help me out here!

I have OLD imacs. The one I'm on now says 2017 and according to some homework, the latest version of Firefox I can run on IOS 10.13.6 is version 115.

WHERE do I FIND that?

I went to mozillas page and there was only one place to update firefox. I went ahead and tried, then got a pop up saying to restart.... did. Then got some helper thing suppose to download, put in my computers password, and NOTHING seems to happen. Nothing at all. Downloads like this usually involve a spinning wheel, or bar showing progress, SOMETHING. I didn't get anything.

Restarted firefox, and every time I go to about firefox to see if it updated, the same pop up shows up. (Will attach a screenshot of it.)

If I look under applications/firefox, it has NOT updated at all.

I'm guessing it's updating to the latest greatest version which MY computer cannot run. SO where do I find VERSION 115?

your updates do not work and repeatedly we messages to update your browser that never does update! so do we have to delete this Linux program to replace it with something that actually works or are you willing to fix the glitches in your system?

After the 8/5/25 Firefox update the internet is inaccessible on my laptop through the standard Firefox browser. The internet is accessible with MS Edge. Toolbar is set to always show bookmarks but none appear. Also, the browser's application's menu does not open to access options such as restore previous session, recently closed tabs, etc. I've restarted my device several times without it resolving the issues with the standard browser.

The Firefox developer version opened in command prompt safe mode (firefox -safe-mode), which is how this inquiry is being sent, but no bookmarks on tool bar or current page history from the standard (non-developer) Firefox.

I'd like to return to accessing the internet using the standard Firefox version with its bookmarks, history, etc. I am using Windows 10. Thank you.

using 64 bit Linux here.

I download an update, but it doesn't do anything. It constantly tells me I need to download an update. Currently using 133.0.3

I managed to get an update through Linux, but now I'm having trouble with Linux. I suspect I need to remove Firefox and reload it. I tried to do that one time but it didn't fix the problem.

Any help would be appreciated.

Downloaded an update of firefox. Is this for real? A message box came up and said I would get a NEW version of firefox but all my things would be saved. Now I have two firefox versions. My old version has all my info and saved and/or chosen settings. HOWEVER the newer version is a new install without settings and WORSE it has GOOGLE as the browser?!?! Is DUCK DUCK GO gone to goOgle? If I wanted a shopping app I would use my GOOGLE account instead of Firefox. How do I fix this?

Hello,

Today I updated to Firefox 143.0.3. When done (most of?) my add-ons were gone, in particular all my add blockers, facebook container, etc. Also, my search engine defaulted to Google (yikes!)from Duck Duck etc. I am very specific about trying to block all ads, trackers, etc and avoiding all Google products. Other things stayed the same like cookies preferences.

Is this done by design? Is there a file somewhere that still has all my add-on info, that I can restore.

I really would give up on browsing if I am forced to see ads all the time.

Thank you! Petrus Martens

Help! All my bookmarks have disappeared from the Firefox browser. I believe there has been a browser update done by Firefox. I found various ways to recover bookmarks and found a folder named 'old Firefox Data' on my desktop. But all files I try to import give me an error message stating that this file doesn't contain any bookmark data. I tried to import bookmark files and favicons.sqlite files. No luck. I now cannot access bookmarks accumulated for about 10 years. Really need to get them back into this new browser. Any advice highly appreciated.

(Win11Pro) If I allow Firefox to update itself from 123.14.0 ESR to 140.3.0 ESR (now apparently 140.3.1 ESR), the update apparently corrupts something in the browser so that it does not respond to the entry of ANY URL. I have to restore a backup of my C: drive, losing some recent data every time. As it stands, I cannot update Firefox beyond ESR 128.14.0, which is what I'm using now. What should I do? Do I have to switch to another browser? Thank you for your help with this. --AnneF

I'm running Firefox 139.0.1 on Mac Sonoma 14.7.1.

Since FF V138, I've had this extremely frustrating problem where, approximately once a day and while the application is still running, Firefox seems to either auto-revert to an older version' 'or otherwise mess up the installation files. I don't get any notice this is happening until I try to open a new tab and it brings up the "You must restart Firefox" notice. When I click Restart, it pops up with "You've launched an older version of Firefox, so you won't keep any of your bookmarks because that would be unstable" error.

The only way I've found to fix it is to redownload the most recent install files, which, after the fresh install, will allow me to keep using Firefox with my bookmarks for the next 5-6 hours, before the whole process starts again.

I theoretically have auto-updates off; my settings are set to the other option, "Check for updates but let you choose to install them". Doesn't seem to make a difference. It only does this on my Mac; the FF install on my Windows machine works fine.

I really want to keep using FF. It's my preferred personal browser. But this is really messing with me! I was hopeful that 139.1 would fix it but same issue, so far.
