Firefox Community Forum

Last week, all 11 of my Firefox extensions, which I've been using for years, were suddenly disabled. For each I got the same message: "[Extension name] could not be verified for use in Firefox and has been disabled." Following Firefox's instructions, in about:config I switched "extensions.langpacks.signatures.required" to FALSE, restarted my computer, but nothing changed. I tried reinstalling the extension Adblock Plus from Firefox's own list of add-ons, got the message "Installation aborted because the add-on appears to be corrupt." Any idea what's going on and what I can do?? Thank you.

iMac OS 10.11.6 El Capitan; Firefox version 78.15.0esr (64-bit)

On my Macbook Pro — OS 12.7.6 Monterey, Firefox version 136.0.2 (64-bit) — the same extensions work just fine.

The last update did something to my search bar. I still have it, but when I click on it, it moves to the upper left corner, prevents me from seeing my tabs, bookmarks etc. How can I disable this annoying change? If someone has the answer, I would greatly appreciate it.

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.

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

After updating Mozilla Firefox to the latest version, it changed the default language from English (US) to German (DE) although English (US) is currently selected as the default language. It will not change back to English (US)

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

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 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?

Please indulge this silly question. What possible benefit is there for Mozilla continuing to list this page with the very first, oldest Firefox release at the the top, requiring the user, every time they visit, to scroll to the middle of the page to search out the current latest version instead of having the chronological order from latest to oldest instead?

I am told that when FireFox closes it is supposed to delete a file called parent.lock in FireFox's Profile Folder. The parent.lock file does not delete when I close FireFox and consequentially it will not allow me to open a new instance of FireFox. If what I say is in fact true, what can I do to fix it? If what I say isn't the case, what can I do to make FireFox open a new instance of FireFox once I close it.

I sure hope I have explained this so it can be understood. When I close FF and then try to open it again, I get a dialog box saying FF is already open and has to close first. Not sure if those are the exact words but I was told that the parent.lock was to be deleted and that isn't happening. What can I do? Thanks.

After recent update bookmarks disappeared. When I restore them and then close firefox developer edition the bookmarks toolbar is gone again. It seems like a bug in that recent update. Please advise.

Hello team, When using Firefox to access an application that calls for Java applets, I receive a message saying "frmserlet-3.jnlp. Application not found." (screenshot attached). This did not happen before October 2024.Please help me with a solution. Thank you!

Earlier today I was trying to watch Prime video and I kept getting an error saying that Firefox wasn't updated (which it was). I looked up some solutions, one of which suggested turning the DRM setting off and then back on. That was a mistake, because after that, any time I opened Prime or netflix, the error I got was "Firefox is installing components needed to play the audio or video on this page. Please try again later. "

Then, I looked that up and found out that my Widevine was just not installing. So, I found an alternative way to manually install it, which shows that it is installed in the Add-ons Manager, but I keep getting that error and nothing works. Prior to this my Netflix was still fine and working.

I've tried a few other things including closing firefox, refreshing firefox from the troubleshoot settings, and restarting my computer.

I am out of ideas, and I wanted to see if anyone can help me before I have to jump ship to another browser.

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
