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.

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 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.

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?

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

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

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".

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.

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:

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

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

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!

I have got a message: "Error: Platform version '130.0.1' is not compatible with minVersion >=130 maxVersion< =130.0" I can´t get any connection. What am I going to do and how can you help me?

Regards Mats Å.

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'm not able to uninstall PWA apps created in Firefox 143.0.1 using Windows 11 usual uninstalling procedure. If i click "uninstall" in Windows Start Menu the app remains installed. PWA apps created with Firefox do not show on Windows 11 installed apps list so I cannot uninstall them. I haven't found any guide on the web on how to uninstall PWA created from Firefox. So, how can I effectively uninstall those PWA apps? Thank you in advance for your kind answer. Regards.

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...
