Firefox Community Forum

Hello all,

During clean-up of my laptop I noticed 31 language package files in C:\ProgramData\O949. File names look like: langpack-en-US@firefox.mozilla.org, and they all originate from 23-Jan-2017 so I guess they're very old files which might be relevant anymore. As these 10,058 files occupy 56 MB I'd like to remove them from my laptop.

Does anybody know if such task is wise, not harming current running FF v131.0.3?

Hello, could you please let me know if updating Firefox as suggested (version 128) will be compatible with my iMac OS X Version 10.9.5. Thank you very much. Kind regards AS.

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.

Ever since a few weeks ago, some of my add-ons as well as every new add-on I added after that are unavailable at the start of Firefox. I then have to click into the application menu, click on the warning message for that add-on and enable it again. Since this is quite tedious and frustrating, I tried looking online for any info. I tried updating everything, disabling and enabling manually and removed and re-added some if the add-ons that cause issues.

I am loath to set up a fresh profile or reset all add-ons as that would cost a lot of time to configure everything again. In hopes of a solution that avoids that I am asking here now.

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.

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?

So I just noticed after downloading the new update to Firefox, version 139.0.1 that something new came up in my task manager called Crashhelper. Never seen this before. Closed it down and it seemed to have no issues shutting down at least. I haven't had Firefox crash in recent months, so I'm assuming that this cropping up might be a glitch of some kind? I looked this up to see if anyone else had this issue, and it seems someone on Reddit did encounter this, on Linux, and another on Windows also seems to have run into it. How do we stop this from coming up whenever we start up the browser?

Good morning,

When I attempt to download the Firefox 115.16.0esr 32 bit download from the site it will only supply me with the Firefox Setup 128.3.0esr. I have tried several times with the same result. Given my PC is far from thr newest (funding prevents large outlays) I must continue with my older 32bit system but try to keep as current as possible with updates.

Please can you advise as to what is going wrong or where I can download the update I need?

Many thanks in anticipation,

John Andrews

Ever since I updated to Firefox 132, I get a Tab Crash if I go to Facebook (logged in), DSLReports Forums (like https://www.dslreports.com/forum/vzfiber), and Rockstar Social Club (logged in).

I have tried playing with the settings, Troubleshooter Mode, and Private Windows...all the same result.

After doing an update on my macbook air, I opened firefox and selected restore previous session (which was a selectable option). However, the window does not appear anywhere, even though when I click on the icon in the dock, it shows that the window exists (so my session was correctly restored, but its not visible at present). Any help?

Hi, using Mac OS. Have tried the about:config set the auto update configs to false, still it keeps prompting every day or a few hours . There is also a timer setting. They dont seem to work, and these update notifications are very irritating, keep popping up every 8 hours or so.

Not sure the necessity for these incessive updates every day or hours, it uses a lot of system resources and hdd space, can Firefox put back the option when we can just tick 'update only when we want them' , in these, no background timer required they use system resources and there are many of us do not want them.

Hi, I just finished writing a few lines of javascript to automate bookmark management. I tested my Addon using about:debugging > Temporary Extensions, and now I'd like to keep the extension loaded across firefox sessions.

What is the best process for doing this? I attempted to create a .xpi file but when installing via "about:addons > Install addon from file" I get the message "This addon could not be installed because it could not be verified".

What is Firefox's self-signing process for this? I don't want to have to install dev versions of the browser just to automate one task.

I think started some time this year, I can't find a Firefox download that installs without admin rights from official website. The .exe and .msi options all require admin privileges.

1. Is there still a no-admin-rights version available? 2. If not, why was it removed? 3. Any plans to bring it back?

Dear folks , Every time I click on Firefox for web search , Fragilepottery.com comes up , I simply cannot find a way to delete Fragilepottery , should I uninstall Firefox and install Firefox again ?

Is there a way to leave/revert from the Beta Update channel and go back to the regular release channel and keep all my current information like my user/favorites/history, etc.? I am on a Windows 10 desktop.

Thank you!

Got this error message on recent update and now Firefox doesn't work at all. Platform Version '131.0.3' is not compatible with minversion >= 131.0.2 maxversion <= 131.0.2

Since Mozilla Firefox web browser v127.0 (released June 11 2024) the manual installation of the Adobe Acrobat Pro extension (the adobe_acrobat-1.0-windows.xpi file) do not work anymore!  :disappointed_face:

So, when you go in any higher version of Mozilla Firefox web browser then v126.0.1 (released May 28, 2024) to this web browser Menu Bar -> Tools -> Add-ons and Themes -> Extensions -> Install Add-on From File..., and then try to manually import-install the Adobe Acrobat Pro extension (the adobe_acrobat-1.0-windows.xpi file) into the Mozilla Firefox web browser, and from this HDD location:

C:\Program Files (x86)\Adobe\Acrobat DC\Acrobat\Browser\WCFirefoxExtn\WebExtn\signed_extn\adobe_acrobat-1.0-windows.xpi

The Mozilla Firefox web browser will say during this .xpi file installation: "This add on could not be installed because it appears to be corrupt"!  :disappointed_face:

However, in any Mozilla Firefox web browser version prior v127.0 (released June 11 2024), this manual import-installation of the adobe_acrobat-1.0-windows.xpi file will be most successfully installed in a Mozilla Firefox web browser without any problem!

I also create the most detailed and step-by-step post on the Mozillazine.org Forum and the Adobe Forum about all of this problem:

So, please help and advice further. Thank you in advance and best regards!
