Hello,

I've tried running "firefox -P". I've also tried deleting ~/.mozilla. No matter what I do, I still keep getting this message.

OS: Linux 6.10.13-3-MANJARO Firefox versions: firefox 131.0.3-1 installed from the Arch repo via pacman; also firefox-132.0.2 installed from tarball downloaded from firefox.com and unpacked as /opt/firefox.

With firefox 131.0.3-1, I get the following error message:

[Parent 33389, IPC I/O Parent] WARNING: process 33445 exited on signal 9: file /usr/src/debug/firefox/firefox-131.0.3/ipc/chromium/src/base/process_util_posix.cc:335

With firefox-132.0.2, no messages are printed.

What is even more confounding: I have 2 user accounts on this computer. When I login as myself, I get this popup. When I login as the other user, firefox opens up fine.

I've already looked at the following, but that has not helped. https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles https://support.mozilla.org/en-US/kb/how-run-firefox-when-profile-missing-inaccessible https://support.mozilla.org/en-US/questions/1327628 https://support.mozilla.org/en-US/questions/1396772 https://support.mozilla.org/en-US/questions/1454745

I'd be most grateful if someone could please suggest any other alternatives to try. Thanks!

Hi James Your reply does not answer my question - "Could you please advise a work-around to allow me to continue to use Firefox V 94.0.1 reliably after 25 March 2025". Thank you. Also FYI, I indicated that I was continuing to use Firefox V 94.0.1 (64-bit) on Windows 7 Professional. This is because all versions later than 94.0.1 modified settings which had to be reset after an update. This was not necessary up to and including V 94.0.1 Cheers Graham Garden

Currently on 131.0.3. Started having this issue around the time 131 dropped.

I press Ctrl-shift-O and bookmarks manager won't open. Bookmarks manager opens normally if I use the menu to open it. Keybind won't work in troubleshooting mode so I know it's not an addon, and the hotkey works fine on other computers with Sync enabled so I know it doesn't have to do with my synchronized settings. Also won't open with a fresh profile so I am very hesitant to reset all my settings.

I use this keybind multiple times per browsing session so it has had a major impact on my usage. Not sure what to do. Please help!

I'm going to try a graphics driver update in the hope that helps. This is on Windows btw.

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?

After an update of both macOS (to macOS Sequoia 15.0.1) and Firefox Developer Edition (to 132.0b3 (aarch64)), the Bookmarks Toolbar stopped working. The same issue appeared on my Windows PC.

Bookmarks toolbar is visible, I can show and hide it but it does not display any of my saved bookmarks. Luckily, they were not deleted and I still can access them via Bookmarks Menu, which is less than optimal.

The Drag&Drop functionality does not work either. When I grab the opened Tab, drag it on the Toolbar and release it, the Tab gets opened in the new browser window and it's not saved.

Hello:

When I signed into my computer this morning, a pop-up asked me if I wanted Firefox to update. I let it do that, and then a pop-up came up letting choose among some photos and art for a desktop background. It even let me upload a photo of mine. I chose one of yours, now I can't change to any other photo I have on my computer. Please help.

Thank you,

Cynthia M.

I already have "Automatically install updates" and "When Firefox is not running" enabled.

But after each Firefox update I still get the "Do you want to allow this app to make changes..." prompt and "Firefox is installing your updates and will start in a few moments" window. These are inconvenient as they require user input and take up time.

I don't get these on all other browsers I use (including Chrome, Edge, Safari, Firefox, Opera, Vivaldi, Brave), which all update in the background seamlessly.

Is there a way to prevent these in Firefox and just have Firefox update seamlessly in the background like other browsers?

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

Running Firefox on macOS Sequoia 15.0. Afternoon of Tuesday, 8 October, Firefox abruptly ceased loading any pages. I eventually learned of the malware incident and downloaded Firefox 131.0.2 last night and overwrote the existing file. It worked for a brief moment, then also ceased functioning. Have downloaded 131.0.2 several times now, with no further success. Currently dead in the water with Firefox, and stuck with Safari. :(

I have a IP intercom that only works with Firefox 127.0.2 Now Firefox automatically upgrades to the latest version and I'm unable to prevent this. I'm unable to manage my intercom with the latest version. How do I turn off automatic updates.

I installed chatgpt, but I've found it more of a nuisance than a help. I've tried on-line to find out how to remove it but none of the suggestions seemed to work. I'm using the latest version of firefox on a Macbook Pro. Any ideas welcome. Charlie

I am not sure what to do first. I already paid for the VPN subscription. I reinstalled Mozzilla VPN but have not yet put the sudo lines in that are listed in the help on Firefox. Can you send me an email with instructions and any special sudo lines I need to intall so I do not get charged a second time. I heve the recovery code. I am new to Mint. Windows 11 started knocking out my hardware with power surges. Had to come from the operating system itself since the machine is hooked to a power backup that smoothes the current out. Converted everything to Linux. Like it. Life can be cruel... LOL Thanks so much for the effort. [edited] landline, but best bet is email. [edited phone# and email from community support forum]

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

Firefox auto updated when I opened it today. Then when it opened, all that was on the screen was the menu (file edit view history bookmarks tools help), the "search or enter address" box, and in the upper right hand corner the words "private browsing" with the purple circle and eye eyeglasses icon. That's all. I have tried looking at my profile. It seems to still be there. This seems to be a problem with the Firefox software itself. I have re-downloaded the software three times, the last time I uninstalled Firefox from my laptop and totally reinstalled. Every time I get the same results. This almost blank screen. Let me be clear. There is no purple background, there is no Firefox icon, there are no tabs, there is no customized menu bar, there is no search box in the middle of the screen. I'm working on a Windows 10 laptop 64 bit. Please don't tell me to upgrade the Windows 11, the laptop won't take Windows 11. I get the same window whether I open the regular fire fox or the private browsing Firefox.
