Firefox Community Forum

i was using firefox with multiple tabs for most of today, had to shut pc down to run errands. When i restarted pc, firefox would not start, i have it pinned on my task bar/start menu/whatever. I opened my system moniter to see what was going on when i tried to start firefox and the processes do not show up in the process list. I tried a reinstall with the ubuntu software store and no noticeable change in behavior. Not sure how to get into the profile section, the option for it with a right click on the firefox icon does nothing seemingly. Under normal operations i have seen two firefox processes listed.

Heads up for custom installs: running tbird and firefox on linux, I install both in my home directory for my own ease of updates and portability. I get releases from https://ftp.mozilla.org/pub/ in tarball formats which install in 30 seconds. I recently ran into a problem which I've not seen before. recent d/l of firefox-136.0.tar.xz for linux-x86_64. It crashed immediately with err 126. The ff.exe and ff.bin files were for ARM arch. This wasn't easy to locate and I think it was caught but anyone still headscratching may want to see if this is an issue - I had a good 136 on a laptop and overwrote bad install on desktop.

I guess there was an update to Firefox today because everything about my browser was a mess! >:( I have always had the Honey and Pinterest pin it buttons on my toolbar, and they have worked just fine. Now that this nightmare "update" happened, they don't show anymore, even though they are enabled in my settings and all permissions are checked. I am NOT very techy, so please don't reply with a long technical response that requires me to spend an hour trying to fix it. The buttons showed before, so why not now?! Please help! I've cleared cache and cookies, cleared history, everything I can think of and nothing is working. :'( TIA

Hello, I have an issue with installing other extensions. Every time I have been trying lately it keeps prompting me to check my internet connection. I have checked it, it is fine, going strong, supporting constant gaming with no lags or spikes, I have no VPN active when trying to install. Are extensions no longer supported by newest mozilla version or something? It is the only browser with this issue and I will switch the main browser if I cannot get extensions to make life easier.

Hi, I used Firefox browser at work since it had the best add-in for tab groups (Simple Tab Groups). Unfortunately browser is not supported any more. Is there a portable version that can be run without installing, from Mozilla.

I read a post that indicated it was available from PortableApps, but am not conversant enough to know that it's 100% safe. Believe that it was able to be updated as well.

Windows 11 system; currently running 131.0.3 (64-bit).

Was offered the chance to update to 132.0 (About | Help) (I do not and will not ever allow automatic updates without user approval, and my profile is stored in an entirely separate folder structure well away from the insecure \users hierarchy). Did the usual click on the update button, showed 132.0 downloading, update button changed to "Restart to Update", clicked the button...

And the update failed. Help | About shows 131.0.3, and the "Restart to Update" button is still active.

Tried again with a full shutdown instead of using the update button, same result.

So how do I force this update to install?

Hello,

today I have installed new OS and new Firefox.

Because I was syncing everything I thought after login everything will be same as before.

Before reinstaling OS I didnt export anything from Firefox. Now I have no bookmarks, no history, add-ons.

I do keep Lockwise on my iPhone and it connected somehow with my desktop browser so I have passwords in my browser now (thank god for that - otherwise I have no clue how they got there).

Is there a way I can restore Firefox (bookmarks and add-ons) to how it was yesterday?

I dont have firefox install elsewhere, just on my desktop.

Thanks a lot for help

I tried to open Firefox and a message appeared: "Couldn't load XPCOM". I uninstalled the program with Revo Uninstaller Pro and downloaded the latest version. I selected Run as Administrator but there is a message that says "Windows cannot have access to the selected device, path or file. Maybe you don't have access rights". However, I do have access rights. I have checked it multiple times. How can I install Firefox and see it work properly? Thanks

Κατέβασα το Firefox Installer.exe και προσπαθώ να κάνω εγκατάσταση με το Run as Administrator διότι για κάποιον λόγο δεν με αφήνει διαφορετικά, αν και έχω δικαιώματα διαχειριστή. Μου βγάζει όμως ένα παράθυρο το 7-Zip και μου λέει "Δεν επιτρέπεται η πρόσβαση".

I am currently running Firefox on desktop (128.4.0esr) version.

The last few addons that I have installed are not working properly. Or rather, they work just fine, but when I close Firefox and re-open it later, they seem to fail to actually enable. I must go to the about:addons page, disable the addon, and then re-enable it for it to actually work. If I do not do this, it will not be on my toolbar, and the Extensions sidebar button does not show the addon in the list. It's as if it isn't properly installed.

After reading this post: https://support.mozilla.org/en-US/que.../1420017 I thought maybe my extensions db got corrupted somehow, so I followed their instructions and deleted the extensions.databaseSchema config. And wouldn't you know it, it worked! Once I restarted Firefox, I saw some notifications in the main sidebar menu and was greeted with this: Notifications Once I clicked through them and enabled, everything seemed fine.

However after closing firefox again, the problem comes back. Those exact extensions that I manually approved upon restarting are the ones that are giving me troubles and not enabling properly. An interesting thing I noticed is that these all seem to be extensions that require additional permissions. I enabled the addon and gave them the permissions they requested, so I don't know why they are failing to enable properly on startup.

I want to permanently fix the problem

Team, I am a longtime user and supporter of FF. I can't tell you how much I love the the layout of Firefox on Windows in v. 133 with the vertical tabs. Just as important is the fantastic, new font rendering. Thank you so much. I used to make multiple adjustments to the font in about:config when I installed FF on Windows. Now, the fonts look fantastic out of the box. Great job, team!

Good morning,

We are seeing that the key "DisableAppUpdate" being set to TRUE in about:policies. Not sure why this setting is being set. The result of the setting is "Updates disabled by your organization". So we cannot manually update firefox and are not sure why the setting is being set.

We used Procmon to capture logs:

Line 5169544: "2:29:45.2062951 AM","firefox.exe","1720","RegEnumValue","HKLM\SOFTWARE\Policies\Mozilla\Firefox","SUCCESS","Index: 0, Name: DisableAppUpdate, Type: REG_DWORD, Length: 4, Data: 1" Line 5169546: "2:29:45.2063211 AM","firefox.exe","1720","RegEnumValue","HKLM\SOFTWARE\Policies\Mozilla\Firefox","SUCCESS","Index: 0, Name: DisableAppUpdate, Type: REG_DWORD, Length: 4, Data: 1" Line 5169547: "2:29:45.2063338 AM","firefox.exe","1720","RegQueryValue","HKLM\SOFTWARE\Policies\Mozilla\Firefox\DisableAppUpdate","SUCCESS","Type: REG_DWORD, Length: 4, Data: 1" Line 5169548: "2:29:45.2063563 AM","firefox.exe","1720","RegQueryValue","HKLM\SOFTWARE\Policies\Mozilla\Firefox\DisableAppUpdate","SUCCESS","Type: REG_DWORD, Length: 4, Data: 1"

Is there anything in Firefox that can trigger the setting of this key?

I had to reinstall Firefox on laptop B. Initially I copied the profile folder back, as I had a recent backup. However, when I sync'd, it deleted a bunch of extensions - which then sync'd and deleted them from laptop A too.

I got them back (manually) on A, deleted the new installation on B, then reinstalled and resync'd (without copying the profile folder). Same thing happened, except as I wasn't coming from the profile, I'd also lost a bunch of settings. So even worse.

My theory (based on the popup about syncing with a mobile device) is it is, for some reason, syncing with my Android phone config (which doesn't have all the same extensions, as they're not compatible) instead of my browser on A.

Has anyone else encountered this? Any solutions?

Dear friends, I recently realized that Mozilla Firefox does not support Windows 7. At the same time you want people to prefer your browser. Why did you stop supporting Windows 7. I think that window 7 is an OS used from thousands of users. I prefer to use this OS and Linux Mint. So, I do not understand your policy not to support this OS. Thank you in advance for your answer!

After a windows update I get the following message when I try to open Firefox: The procedure entry point ?ToLogLevel@mozilla@@VA?AW4LogLevel@1@H@Z could not be located in the dynamic link library C:ProgramFiles\Mozilla Firefox\xul.dll Then I get Couldn't load XPCOM

I tried uninstalling firefox but it just hung. I restored it to before the windows update but still got the same message

I have been using a usrChrome.css in my profile to create multi-row tabs. (Why cant Mozilla see the need for this with 4K monitors?) The Oct update broke this and I cannot get FF to load the css file that has worked for more than a ywar.

Help please?

Hi,

First, I went to Firefox > About and it updated to: version 115, so then I downloaded Firefox extended support release [ESR] for mac from this site; while downloading; closed Firefox browser; and once finished downloading, I dragged to the 'applications folder.' Once there I clicked, "open" and it's still showing latest version: 115.

In Settings > Add-ons > Manage extensions, I have the following:

Adblock + Brave is disabled

DuckDuckGo is enabled

• I do not have Firefox showing at all.

Please advise what to do next.

Thanks

I've just been told by my Firefox Browser that there is an update available but it can't install it automatically, I need to manually download the file and install it. It took me to an Enterprise page which gave me the choice between a Rapid Response version or an ESR version. Firstly why an Enterprise page? Secondly which version do I need fora PC running Windows 7 Pro 64 bit please?

I have used Firefox for longer than I care to remember and have never had any problem with it but this morning I switched on my PC and a new AI side bar has appeard on the left and I don't want it. Can you please make it so we can remove it and looking around the internet, I know I'm not the only one with this opinion.

Is there software that will being me (more or less) up to date? I'm pretty much computer illiterate, so keeping it simple would be greatly appreciated. Buying a new iMac and transferring files is a last resort...
