Diễn đàn hỗ trợ Firefox

I am still using Win 7 but converting to Win 11. The most recent "patch Tuesday" update from MS killed Office 2016. Since then Fire Fox will occasionally pop up the "Couldn't load XPCOM." (no file extension) warning. It may do this when opened but not always. Can also occur in the midst of a session.

Program seems to be working correctly but some of my pinned locations disappeared when this started. New locations are retained between sessions. Is there a problem with continued operation with this warning? Is there something that I can do to repair it.

I can not open my firefox browser. I never had this problem before. When I click on the icon I have on my bottom of my computer it says I can not get on it says many different error messages being sent. I am not a computer whiz so what should I do? should I uninstall it and re-stall it? would I loose everything I have book marked. HELP

I use translation A LOT. (I'm learning a foreign language.) It would help to be able to move or resize the results window. Right now, it covers the original foreign language text. I want to compare the translation with the original text and the fixed size and position of your results window makes that a lot more difficult.

Whenever I close Firefox and try to reopen it, it brings up a system error that says, "The code execution cannot proceed because C:\WINDOWS\system32\pmls64.dll was not found. Reinstalling the program may fix this problem." I've tried completely deleting Firefox and reinstalling and it opens a new tab, but when I close it i get the same error message.

When I first open Firefox from the icon in my taskbar the opening window says the following:

'Unable to connect Firefox can’t establish a connection to the server at 0.0.0.4. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer’s network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.'

However this is only the first window, after that I can open a new tab in the same window without any problems.

I have uninstalled and reinstalled Firefox without avail. Can anyone help please?

Firefox won't open. System says it can't find VCRUNTIME140.DLL. There are SEVERAL copies on the drive. I believe I Refreshed and Reinstalled? And still cannot run.

This is the first time Firefox has failed in years. There are no instructions for this specific problem. FWIW I just installed AURA seemingly without problems.

Richard PS - Wouldn't it be great if the library of proven volunteer responses was searchable? r

Lately every time I open Firefox on my PC (Win 10) it says that it is already running and that I need to close it first. How can that be if I just started the computer session?
