Firefox just turns into a black screen and becomes unusable. It has been happening for a long time now and i have checked RAM and CPU usage and they are all fine, as I explored potential causes.

I will be using firefox and it just turns all black on all screens and is completely unusable. To use it again I have to force close all windows and reopen it and it works again.

This is a frequent issue that I have seen

When I open a website where there is a document upload feature and I want to upload a document but when I click the button to upload a document Firefox can't respond, I've tried several methods such as deleting cache, even reinstalling but I still encounter this problem.

I can't add images to this report because of this problem

Thank you

Possibly there was an auto update of MOZILLA FIREFOX on our DELL LAPTOP (Windows 11). Now, we cannot get a Mozilla window to open - due to error message:

XUL Runner Error: Platform version '118.0.1' is not compatible with minVersion >= 118.0 maxVersion <=118.0

Can someone please help us get back to a previous version of Mozilla Fire. Perhaps it is a Windows error. I have no way of knowing. Please help me. My email is: [removed email from public] Thank you.

So for the last little while, Facebook has been making a complete nuisance of itself on firefox. This isn't a browser problem, because the other tabs I have open work perfectly fine, but FB takes forever to load, and any button I press to interact with it, (like the reload button,) also lags, (but, again, works fine on other tabs,). It doesn't even register links as being clickable for a good minute after loading. The page also seems to reset every time I switch from another tab to it, showing a blank page with a loading symbol. I have tried deleting the entire history, and restarting the browser, and deactivating the adblocker, (the only extension active) and nothing seems to help. Does anybody know why it's doing this, (other than because the company follows the 'if it isn't broke, break it' theory, which we all already knew,) and how to fix it?

Hello.

I'm using Firefox on windows 11 home 22H2. After the recent update to 118.0 I've been unable to load yahoo.com.

I tried the following: Disabled addons Disabled firewall Restarted firefox Restarted computer Restarted firefox in troubleshoot mode

I'm out of ideas except for a downgrade maybe.

Does anyone have any suggestions?

On a site with a menu along the top the rightmost item is missing, and only in Firefox, not Chrome or Edge. It happens on various pages with the same menu setup. I cleared cookies & cache, turned off extensions, no luck. See attached image. What could the problem be ?

Everything was working fine on Firefox up until a couple weeks ago when my searches started lagging.

What happens is - if I type a search into the main URL/search bar on the browser, it loads just fine. But if I type a 2nd search into a website search bar, such as on google.com, there is about a 12 second delay between me hitting enter and the page actually starting to load. The page freezes during this time and is unable to be interacted with. This issue does not happen in any other browsers outside of Firefox.

Things I've tried so far: Troubleshoot mode/safe mode, clearing cookies and cache, uninstalling and re-installing Firefox

Nothing has helped... wondering if this was caused by an update?

continue in /questions/1424778 in Thunderbird section.

Having used Thunderbird for some time, I installed it on a new PC, and found that virtually all my emails on a particular account seem to have been deleted, despite the app being set up to retain them. I checked on the webmail (BT) and they have gone. The account is set up as IMAP - as is another account on the same server, which seems OK. BT won't engage with me on this as they "don't support third party apps" I assume that 3 years worth of important client history is gone for ever? Can anyone suggest what I did wrong, or is this a software failure?

Firefox displays websites with gibberish for headlines. I've monkeyed with the "Fonts" preferences in the Settings to no avail. Perhaps I'm not choosing correctly. They are currently set with Firefox's defaults and the box allowing websites to choose their own fonts is also selected. No matter what I've done, it looks like the attached image. Help!

When I'm trying to go to a specific website, it doesn't connect with an error code "SEC_ERROR_UNKNOWN_ISSUER". I was able to press a button labeled "Accept the Risk and Continue" before, but the button seems to have disappeared?

When writing reviews in Google Maps when you click post pictures from your computer (allowing one to browse your computer to find pictures to post) the tab crashes.

This occurs on other websites as well where one would browse the computer to attach documents, photos or videos. Heck, it even happens with this site (selecting browse to post picture causes firefox to crash).

This did not occur prior to updating to 115.0

Windows 11 operating system

I am unable to log into facebook after inputting my password and 2FA. disabling all addons does not help. It is stuck on the "This was me" screen in an infinite loop.

For a few weeks now, Firefox has been often freezing a webpage for 5-10 seconds during browsing. It mostly happens when going back to the previous page, but also when clicking a link or doing a google search. For those 10 seconds, you can't do anything on the page; no clicking other links or selecting text.

I've already tried: - troubleshoot mode; it still happens when all extensions are turned off - turning on/off hardware acceleration - creating new places databes - updating to the newest version

What can i do to fix this?

When i go to google.com and enter search query the tab "hangs" for about 10 seconds before the next page starts to load Same issue on 2 separate machines (1 intel laptop, 1 amd pc) both on newly installed windows 11 pro

what i've tried: safe mode, disabling hardware acceleration, disabling antivirus (kaspersky, without any browser plugins or safe browsing) , but the issue persists

here's the video: https://youtu.be/qMY-38z_TC0

I ran a loghttps://pastebin.com/jydVHHs0 of playing a youtube video mediaencoder? not sure if encoding issue or something else

The videos take a long time to play. I upgraded my system recently and was removing and reinstalling audio-related utilities with DNF.

I got a notice that Firefox (and Thunderbird) were updated this morning. Took me an HOUR to find out how to make the miniscule font in my inbox larger. So.. suddenly, new problem.

When I click the Firefox icon to launch the browser, and reopen my tabs, It opens for a millisecond, then closes faster than I can try to read if there is an error. When I click it AGAIN, all my tabs are GONE and I have to search for them manually, which is a royal pain.

Why is this happening? How can I stop it from happening? This is annoying as hell.

Hi,

I am using Firefox for Linux, and whenever my yubikey is plugged in, firefox will start bothering me for a pkcs#11 password. It always happens on start-up but it gets relentlessly annoying if I happen to be on a site which potentially utilizes certificate auth, which I do not use this yubikey for.

I do however use it for 2fa, which does work perfectly fine.

How do I permanently stop whatever Firefox process keeps bothering me about this PKCS#11 password for functionality that I never use?
