Firefox Community Forum

Hi,

I seem to be having a really odd issue where each time I restart Firefox, recent addons I've installed will not function or appear in the Add-On drop down menu (despite being meant to appear in such), despite being enabled and still being shown as such when I check settings. They only become visible and functional when I disable and re-enable them.

I've just discovered the same thing seems to happen in reverse too. I recently disabled ClearURLs due to a bug it was causing in Google Drive, yet it appeared in my Add-On drop down menu after restarting. Checking settings showed it to still be 'disabled'.

Things I've tried:

• Restarting both Firefox and PC.
• Uninstalling and reinstalling the effected Add-ons
• Deleting my extension*, compatability.ini and prefs.js files - erasing all my add-on settings yet still not helping. This is the main thing I've suggested on forums like this with similar questions, but has not helped.

It seems to only be effecting the most recent set of add-ons I installed over the last week, as if Firefox keeps trying to work with the Add-on settings I had at a previous date. I've seemingly had some cases where the extensions disable or are uninstalled entirely but I'm not sure this is related, as I think it only happened once.

I suspect it's not to do with the new extensions themselves, given it's effecting all the most recent ones, but I'll list the ones I've seen it effecting here regardless:

ClearURLS (not recently installed, but as mentioned showing similar reverse effects) Undo Close Tab YouTube NonStop Privacy Badger History AutoDelete Don't Accept Image/Webp Decentraleyes Xkit Rewritten Disconnect AI Grammar Checker & Paraphraser - LanguageTool &udm=14

As you can see I recently installed quite a few anti-tracker type extensions which probably overlap in function, mainly just to test them out, so it could be connected to them I guess... but seems unlikely.

Thanks, Matt

I just updated my iMac from Mojave to Catalina 10.15.7. I thought Firefox would provide an update to convert the esr version to the standard Firefox browser since I am no longer using Mojave, but the next update is 115.15.0esr. Is that correct? My understanding is that the esr updates are just for computers using older operating systems through Mojave. I did not update to 115.15.0esr since I am not sure if that is the right version for Catalina. Any information and assistance you can provide me is greatly appreciated. Thank you.

The most recent update to Firefox, on each of our four Windows 10 systems, has a new glitch when printing PDF files. The particular files we're trying to print are in LEGAL SIZE format, and Firefox is compressing the text into a size that only uses half the page. This is true whether or not we select LEGAL SIZE in the printing interface, and regardless of the "Scale" setting. We had to switch over to printing these files with Adobe Acrobat, which worked fine.

I'm an IT support professional and in our environment we are still running few servers (for multiple reasons) with OS version Microsoft Windows Server 2012 R2 Standard and Microsoft Windows Server 2012 R2 Datacenter and they have currently Mozilla Firefox ESR (x64 en-US) 115.15.0 installed. I couldn't find any clear answer, hence I've created this ticket - is Mozilla Firefox ESR 115.16.0 supported on this OS ? - usually you are not referring to Microsoft Windows Server in you release notes info - f.ex. https://www.mozilla.org/en-US/firefox/115.16.1/system-requirements/ so I need clear answer. Also I cannot download Mozilla Firefox 115.16.1 from https://www.mozilla.org/en-US/firefox/115.16.1/releasenotes/ - if I click download it always downloads Mozilla Firefox 128 instead. So please let me know if there is any Mozilla supported version for Microsoft Windows Server 2012. Best Regards, Milosz Wrzalek

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 have updated Firefox from 115.16.1 to Firefox ESR because I use a Mac running OS 10.13.6. Is there a way, hopefully an easy way, to import all of the bookmarks and extensions I was previously using in 115.16.1 to ESR. Hope so. Thanks!

I bought Mozilla VPN a month ago, and nothing has turned up.

How do I get a refund of my money?

Then I can buy StartPage VPN.

Firefox is really going downhill.

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!

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.

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".

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 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

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.

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
