I have the latest version of Mozilla Firefox 155.0.Every time i update to latest version my Norton 360 for Gamers antivirus Safe Web application blocks the update process and i report it as False Positive and Mozilla Firefox updates ok. I have attached and image of Norton's Safe Web application analysis. Also,have submitted this issue to Norton using their Report False Positive form and have not had a reply yet. Thank you

The plugging is NOT updating and it's blocking me from watching anything on streaming. I've tried triggering the update by turning it on and off, by tugging on and off the "DRM" option in settings, by turning off the updates and then looking for updates... I went to about:config and made sure that all options were "true". What I get is an "error in downloading the update" that I can't fix.

Can someone help?

Need an update for the update. My Mozilla settings say my operating system (Ubuntu 22.04) handles the updates, and it's a deadend. I can only use my browser for one minute before it freezes.

The details:

1.) After downloading the update, my antivirus scanner reports an infected file (see screenshots / message + path).

2.) When I try to “Restart Firefox to complete the update,” Firefox briefly “disappears” (whatever happens there) and then “reappears”—but the prompt “Restart Firefox to complete the update” is still there. Unfortunately, this can be repeated as many times as you like without anything changing.

3.) Restarting the computer (Platform: macOS Tahoe 26.5.1) does not resolve the issue either (see screenshot). I always performed previous updates before shutting down the computer—and the next day (since Firefox, as expected, had been closed and restarted), the updated version of Firefox was running.

4.) The suggested solution is to download the “Firefox installer.” But that doesn’t help me, since I need “Firefox DEVELOPER.”

Would uninstalling Firefox DEVELOPER and reinstalling it >WITHOUT DATA LOSS< be a solution??

After the last update on my desktop browser, my password was requested in order to "install a new helper tool." But it isn't accepting my password, even after I double checked what it was. And there's no Change Password link.

Since I can still access the Firefox browser on my iPhone, I thought of I'd change my password there and sync, but the new password isn't accepted either. Once a password isn't accepted, pressing cancel closes the app and it can't be reopened without a Force Quit first.

And 'round and 'round I go. How do I regain access to my desktop browser?

Thanks.

I can't access the Firefox password manager on my desktop Windows 10 PC. See screen shot #1 from attempt. Further investigation shows a failed update which seems to correspond to the date the access problem started per screenshot #2. Passwords are available on my IOS Phone as normal.

What should I do to restore PW access?

Thanks, Craig Lamison

After updating to Firefox 152.0.1 this morning I keep getting Error 7023 Service Control Manager each time I start Firefox. The error description states "The MozillaMaintenance service terminated with the following error: Incorrect function." The Mozilla Maintenance Service was set to Manual and I set it to Automatic but still getting error each time I start Firefox. I have read that the service can be disabled so what do you suggest I do to stop the 7023 error. Thank you.

Need an update for the update. My Mozilla settings say my operating system (Ubuntu 22.04) handles the updates, and it's a deadend. I can only use my browser for one minute before it freezes and a force quit is necessary.

I wanted to try the new split screen feature. The guide says you need the latest version 149. When I check 'About Firefox' it says I have version 140.9 but it also says 'Firefox up-to-date'. Could you advise how I can update to latest version 149 please?

I've had a problem for a while where Firefox tells me "Firefox is being updated by another instance" and the only way I've been able to get updates is by using the installer.

In my attempts to resolve this, I learned of the `about:profiles`. I have never set up profiles so I figures I should only have the 1 default profile but it turns out I have `default`, `default-release`, default-release-1`, and `default-release-2`.

Of these profiles, the `default-release` is the 1 that has my data while it is `default-release-1` that is able to update.

I would like to make it so that I only have 1 profile that has all of my data AND is able to update.

I already tried removing all the profiles accept the one with my data but that leaves Firefox unable to update. I restored all the profiles I removed and I am back to where I started.

Does anyone have any suggestions?

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

Update fails, apparently in post-refresh hook with the symlinks in /var/snap/firefox/common/snap-hunspell/ pointing to non-existent files in a non-existent directory (e.g. to /snap/firefox/5701/usr/share/hunspell/en_US.aff where /snap/firefox/5701/ does not exist).

A thunderbird update (128.6.0esr->128.6.1esr) fails very similarly.

I used snap to update manually in order to see error messages:

I am running Firefox 149.0 (64-bit) on Windows 10. FF tells me that there is an update. I downloaded the update, and when I restart FF, it does not update. Version 149.0 is re-started, and Help --> About Firefox again tells me to restart to upgrade. I have tried the upgrade at least three times.

Greetings Ya'll,

Early this morning as I went to use the Firefox browser, on My Desktop, I got an update, & then firefox opened, somewhat.

The homepage did not fill in with favorites, suggestions, etc, and in fact all that did load was the Search bar, but not one of my usual website buttons. The "edit", "help", etc. buttons at the upper left hand corner did load, but that is all.

Not one of the buttons work, nor can I close out the Firefox page, by tapping the "X" in the upper right hand corner.

The only way that I could close out the "Firefox Page" was by going through the "Control/Alt/Delete" & then "Signing Out", which would initiate a "Re-start". Once I signed in, I could return to the Desktop, where everything works.

I use Firefox as my Browser on my Android phone, & at this moment, I've not had any problems using Firefox on my Cell Phone.

The only way that I could get to the Mozilla Website was by using the Microsoft Edge Browser, which is not giving me any problems as far as accessing the Internet!

How can I correct this problem, & go back to the Firefox Browser?
