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

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!

I'm trying to install Mozilla VPN but it won't install. The error message is as follows: the installer encountered an error that caused the installation to fail.

I cannot login into a website because they complain that I have an old version of PHP. Is that already included in Firefox? I am using Firefox Vers. 143.0.4 on a MacBook Air with MacOS Big Sur, Vers. 11.7.10 Shall I go to the PHP website and download PHP?

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 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 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

On the latest update to firefox, the browser now has a vetical tab in addition to the horizontal ones. I want to remove the vertical tabs, and ideally for it to never come back. I've searched the settings as well as the support features and can't find a way to turn it off. I am legitimately not going to use firefox at all until this issue is resolved.

Thanks

Win 11 stopped working on my Lenoovo Yoga due to bitlocker key requirement that does not exist I'm in the process of installing Ubuntu during the installation something went wrong "system program problem detected" which stopped the installation

I have loved FF desktop browser since I started using it per my boss in 2003. But I am so tired of the fact that EVERY SINGLE TIME you put out an update it breaks my access to the bank. EVERY SINGLE TIME. I waste HOURS reading articles, calling the bank IT dept, chatting with people who are on 3 calls at once, only to hear them tell me to "just use chrome." I clear the cookies, clear the cache, reboot, follow all the prompts in the settings and THEN the damned bank server doesn't recognize the device so it forces yet ANOTHER password change. It happened again TODAY and it makes me so sad but I cannot do it anymore. I am STILL now (going on 4 hours) trying to access the billpay page @ Xantanderbank. (ahem, secure codename) I am forced now, by this craziness, to use the imbecilic duckduckgo which is A) and offensive name and b) you KNOW it nowhere near the product you have built but I CANNOT DO THIS ANYMORE. Thank you for the time it takes to read this diatribe. I appreciate it.

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.

I have a custom pitch black theme ( pls add it without addons ) which now only flashes for a second when i open the browser and returns to the normal greyish dark mode. When i go to Firefox Color addon page and load it again in saved themes it stays pitchblack even if i open another browser window until i close all the browser windows .

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.

That is the first line in the Hippocratic Oath. All doctors have to swear to it. All software developers should too.

I made the mistake of letting Firefox on KUbuntu update. It obliterated all my tabs and all my history. There's nothing left. I had a lot of tabs open with intent to use them to update some astronomy instructional activities. I don't know if I'll be able to find them again.

I don't really have a question except to ask: What fresh hell is this? Is it really that hard to just leave things the hell alone? I'm afraid to ever update Firefox again. If everything else wasn't based on Chromium, I'd be out of here.

Also, it looks like something out of Windows 7.

It's all gone. It's a wonder you didn't delete all my bookmarks while you were at it.

How much longer will Firefox be down due to server updates on Mozilla.org? ALL of my extensions are disabled for that NLT 15 minute update that's been going on for well over an hour (I know, because my extensions are still disabled and have not yet reset themselves---Mozilla crapping them out, Mozilla returns them to my setup---to the way I had them configured. Specifically, the ones I'm missing the most right now are Tab Sidebar, Tiled Tab Groups, and whichever one(s) make bookmarks/new tabs open in a NEW tab, not clobbering a tab that is currently in use. I did that to open Duck Duck Go a minute ago, and had to re-write this whole support question because, for some reason, Duck Duck Go opened up in this ACTIVELY IN USE tab instead of a new tab. And not only that, it wiped the contents of this support chat window. Sorry, but that is totally UNSAT.

Thanks, jim74, [edited] @jdgblogs.com (which needs to change to [edited] @jstrack,net---how do I do that?), Firefox ESR 91.5.1esr on Slackware v. 15.

In the last update of Firefox, today, the updated firefox opened without some bookmarks that I had open in the last session and that I don't want to lose. I tried the recovery following your help (Recover user data missing after Firefox update) but without success. How can I recover lost bokmars? Note: This situation has happened more times and if I can't recover the bookmarks, I will have to give up Firefox, which I have been using for many years and stop recommending it.
