Firefox supportforum

The new Mozilla Firefox (version 110.0) does not run after update on my system. After run it shows the window, but this window doesn't respond. The clean installation (of course with profile folder erase) doesn't fix the problem. I have tried both x64 and x86 versions.

The previous version installation (109.0.1) works fine.

There are some screenshots included. I use Windows 7 on Ryzen 7 2700X processor. Could you please advice, what can be done here?

I can't figure out how to install Firefox on Windows 11. Their link gets me to APPS in Setting but from there I'm lost. I can't find in APPS where to allow for apps from third parties. I think MS does this on purpose.

When I try to install Firefox on my Steam Deck (Which came with the installer). It doesn't open. It just says "Cound not open appstream://org.mozilla.firefox because it was not found in any available software repositories.

Please report this issue to the packagers of your distribution." It shows it every time I open the installer ever since I got the thing.

Upon the last update (v.83), my favourite Flash golf game "World Golf Tour" ceased to work.

The makers of the game have already taken steps to move to a different platform on January 1st ... but the existing Flash version still works perfectly ... until YOU came along!

Your so-called "update" made it impossible to even load World Golf Tour's menu screen - I heard the music, but the graphics were frozen.

I'm no Sherlock - but this problem only occurred when Firefox updated.

It took me ages to downgrade back to v.82.3 - but WGT loaded perfectly when I did it.

Proving that it's YOUR fault! So don't give me this "most problems are caused by other peoples' software" stock answer crap.

I WILL upgrade to the latest version of Firefox on January 1st, not one second before.

Is there any way I can turn off the "Download Firefox Update Reminder" until then?

It's really annoying.

So I've disabled Firefox updates because of the personal preferences. It keeps nagging me every day with the modal to update. How do I disable this annoying useless feature?

Firefox 85.0 on mac os.

I've tried searching "about:config" for all preferences that contain "update" and look like timers and changed the timestamps to something in the far future. Still no dice, the update dialog keeps appearing every day like clockwork.

Hello, is there a way to turn off the new print function. I want my print program to open and not a complicated print program that cannot be used by us. Since this new setting, we can no longer print properly and have to do all print jobs with a screen print.

When I try to open a word document from a website via firefox it will not open. Constantly gives me an error message. Been in touch with microsoft word and its not an issue on their side.

I can open the documents via microsoft edge but not fire fox.

I keep getting the same error

Hi,

I installed a security certificate (this may or may not be related) and after this Firefox wouldn't open. It stuck in a loop of "firefox is already running but not responding" - choosing to close it wouldn't solve it and the window would pop up over and over, despite me not actually trying to open it again.

I tried terminating the program in Task Manager and a full system restart, but this didn't solve it.

I have tried uninstalling and have also checked AppData to remove everything here. Despite seemingly removing it entirely, when I go to install from scratch it recognises that I am re-installing... so something is clearly still in the system somewhere.

Attempting to re-install eventually leads to a "Your Firefox profile cannot be loaded. It may be missing or inaccessible," message.

So, I can't install Firefox at all now. Any advice would be much appreciated as I prefer Firefox and I'd like not to be forced to use Chrome! How do I completely remove Firefox to force a fresh install?

Extra info: I have tried everything outlined here: https://support.mozilla.org/en-US/kb/uninstall-firefox-from-your-computer I am on Windows 10 Pro and I am installing as administrator.

Thanks in advance.

Hi,

I am using 86.0.0 on W10. How do I get rid of automatic updates ? [without digging registry, policies JSON files, and bowels]

Why isn't it possible to do that from Menu->Options ?

The last fully compatible version I could use was 78.6.1 ESR. I know I need a new profile to go backwards but I can't find the specific file. I can see the version I would like in a directory but don't know how to download/install it. Thank you all:)

Have 2011 Mac which won't support newer OS updates.

I downloaded a file from my scanner and when I tried to e-mail it to someone, I am told that it does not exist, even though I can open it in Adobe and pdf. How can I download to something that can be e-mailed?

Once again the current update of Firefox (87.0) eliminated the ui.submenuDelay setting. Screwed up everything when I tried to install previous version.

ui.submenuDelay is the most important feature for me. I hate the bookmarks opening on hoover, there is no delay at all.

Please fix and remember.

} REQUEST chrome-extension://mhjfbmdgcfjbbpaeojofohoefgiehjai/edge_pdf/index.html Computer experts, what does this mean? Where do I go and how do I fix this? This is an extremely important document that is very popular right now. PLEASE HELP

Instructions to solve this problem date to 2018 and say it can be done on the Get Info dialogue box of the application, but it can't. I don't want to reinstall. Any other ideas?
