Firefox Community Forum

I have an Arch Linux installation with Plasma desktop. Software is always kept up-to-date. Sometime recently, Mozilla apps, Firefox nor Thunderbird, will no longer print, neither to pdf nor to network printer. These always worked before. Now, if even "print preview" is invoked, the dialog opens as a blank sub window with only the word "Print" in upper right, and at left center is "Preparing Preview with rotating time delay wheel, which never resolves. All other apps, including other browsers and mail handlers, will print without issue. I've tried the obvious checks with no success. Where could be the problem? Is there a helper app shared by Firefox and Thunderbird that could be the issue? The only potential remedy I have not yet tried is complete removal of both Firefox and Thunderbird, as that would cause re-configuration issues for both. It's necessary to press <ESC> to terminate the print window when it fails to respond. Screenshot attached...

My YouTube homepage is blank when I visit using Firefox (see attached screenshot). Here is a list of all of the fixes I have tried:

-Disabling all extensions and turning off Enhanced Tracking Protection (at the same time) -Clearing cache -Clicking 'forget this site' on YouTube in my browser history -Restarting my PC/Firefox -Refreshing Firefox profile (this worked, but the issue returned after an hour) -Changing my system theme to light mode -Launching Firefox in troubleshoot mode -Logging in on an incognito window (with the same result) -Probably some other things I'm missing (I tried pretty much every result I could find from looking up 'YouTube homepage is blank' and 'YouTube homepage not loading).

The issue only occurs on Firefox and only after I log in to YouTube. This has never occurred before. I checked to make sure my Firefox and YouTube settings are the same as they've always been.

YouTube videos load fine as long as I paste the direct link into the URL bar, but ONLY the video (no comments, recommended videos, likes/dislikes, description, etc...) and I can't take it out of theatre mode nor fullscreen it (fullscreening it just removes the top bar of the browser--the video itself still has black bars on the sides).

Sometimes when I reload the page, I see the following at the end of the URL: &ThemeRefresh=1. I don't know if that means anything.

I am using the Firefox app on Windows 11. I am not using a VPN. This issue is specific to YouTube and YouTube only.

Any help would be greatly appreciated. Thanks!

Hi everyone,

I’ve recently started playing Krunker.io (a browser-based FPS game), but I’m facing a lot of lag and stuttering in Firefox. The game runs fine for a few minutes and then randomly starts slowing down — especially during fast action scenes.

I’ve tried the basic stuff like:

Updating Firefox

Using private window mode

Closing other tabs

Enabling hardware acceleration

But the issue still comes back, especially when I play for more than 10–15 minutes. Has anyone else experienced this with browser games on Firefox? Any tweaks or settings you recommend to improve performance?

Thanks in advance! 😊

As the title suggests, I've found that exceptions added for 'Enhanced Tracking Protection' simply do not function in a private window; they're entirely ignored. The discovered 'Tracking Content' (from shield in the address bar) will list the exact domain that's whitelisted and the network tab of the devtools will label the URL as blocked due to tracking content. Obviously this is wrong, that short of per-window type settings, this should be global (and makes no sense to differentiate anyhow).

Switching to a standard window fixes this, however, and the exceptions are taken into account.

Today was the second time in two weeks I have lost every open tab in Firefox. Previous to this, this problem has not occurred in at least 5 years. What is going on? To utilize data from multiple sites takes a long time to relocate sites and this is becoming unacceptable. Firefox updates are better than this. Thank you for your help.

Firefox is not loading on my desktop full sceen. I can see a small page minimalized when I put my curser on the Firefox icon. This has happened once before and I had to uninstall and install and I lost a lot of settings doing that. Please advise. Picture on the left is what I see, not the other.

When I go to the task bar and click on firefox the only thing that comes up is, top left corner it says new tab but nothing opens after that, just blank screen. I want to use firefox as my browser but if this continues I'll have to use a different browser.

firefox did an update this morning when I selected a link on a trusted email. Went as normal but I have lost my homepage. All I have is a blank page where I used to have my most used searches and links. All gone blank page (still have bookmarks drop down) Is this the new look? how can I get my homepage back please? Thanks Stephen
