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've just been told by my Firefox Browser that there is an update available but it can't install it automatically, I need to manually download the file and install it. It took me to an Enterprise page which gave me the choice between a Rapid Response version or an ESR version. Firstly why an Enterprise page? Secondly which version do I need fora PC running Windows 7 Pro 64 bit please?

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?

Is there any Add-on that will shoot a scrolling screenshot (full page screenshot)?

For reference, there's an excellent extension on Chrome/Brave called "Go full screen" which has simple but perfect functionality, one-click automation, saves as either .pdf or .png format to your downloads folder.

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.

I need to speak with someone. Firefox was updated on May 23. I have been away and can not use new version. I can not get access to aol account. I want my old Firefox back

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.

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

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!

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.

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.

On the newest firefox update on Windows PC My PDF reading has been not displaying PDFs correctly on Firefox I tested on other PDF views and they work as normal (All images are normally white with black text PDFs) Sometimes it displays nothing at all (as seen in Image 1) Some pages will display correctly but the rest won't (as seen in Image 2) Some pages will display text but strangely (as seen in Image 3) It does flash white sometimes while scrolling but it still doesn't show text

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.

I'm using Firefox Developer Edition 132.0b3 (64 bit) which I downloaded just a few days ago. Already, there's an update for it, to version 132.0b4. Each time I open Firefox, there's this popup that tells me that there's an update available and that I need to download it. I'm using Linux Mint 21. I've already visited about:config and changed app.update.silent to true, changed app.update.manual to true, and changed app.update.url.details and app.update.url.manual to fake hyperlinks. Despite doing this and despite restarting, I'm still prompted about the update available every single time I open Firefox. Could someone kindly tell the specific developer who implemented this annoying feature, to please provide an option for Users to not be bothered with such popup notifications?

ps: Why does this website have a white background and not allow extensions to change it to a dark background? I have Dark Reader extension installed, but it says that it cannot make changes to this website. Even uBlockOrigin is unable to. Please either allow extensions to change the background, or at least change the background color of this website to dark. It gets strenuous on the eyes to keep staring at a bright white backgrond.

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.

Everything was normal before the update. When I did the update, the menus changed, the bookmarks disappeared, the new tab key disappeared, how do I get it back to its original state?

I looked at the system requirements page at https://www.mozilla.org/en-US/firefox/141.0/system-requirements/ . For Windows devices, the operating systems supported are listed as "Windows 10 or later".

In October 2025, Microsoft officially stops providing feature and security updates for Windows 10. However, they offer consumers and businesses the option of enrolling in 1-year, 2-year, and 3-year subscriptions for Windows 10 devices which will provide another 1-year, 2-years, and 3-years of additional security updates. You can read more about this at https://learn.microsoft.com/en-us/windows/whats-new/extended-security-updates

For those individuals and businesses who will be enrolling devices into the Windows 10 ESU program, will Mozilla continue to support Firefox on Windows 10 after October 2025, at least for those receiving security updates through Microsoft subscriptions? Or at that point will Mozilla consider Windows 11 to be the only supported Windows operating system?

Thank you!
