I-Firefox Community Forum

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!

Anything using WebGL in-browser tells me that my browser doesn't support it.

https://get.webgl.org/ says "Hmm. While your browser seems to support WebGL, it is disabled or unavailable. If possible, please ensure that you are running the latest drivers for your video card." but I updated it to the most recent drivers and the issue is still happening. Graphics card is an AMD Radeon RX 6600 XT.

In the last few days, after some minutes of usage, parts of Firefox become unclickable:

- I can still click on tabs to change tabs. - When hovering over the cross button to close a tab, it changes appearance as it should. Clicking the button does nothing. Ctrl+w still closes the button. - Clicking on the address bar does nothing. - Cannot click on back, forward, refresh buttons. - Cannot click on any add-ons. - Cannot click on preferences. - Can click on the button to open a new tab. There, I can enter an address. Once the page has loaded, address bar becomes unclickable again. - Bookmarks toolbar is still working as expected. - Keyboard shortcuts (ctrl+t, ctrl-w, ctrl-l) still work as expected.

I'm running ``` Mozilla Firefox 138.0 20250428130755 20250428130755 ```

on Manjaro 25.0.1 with GNOME 48

I have tried every support advice I can find and no matter what I do passwords are not restoring. Here is what I have done: Opened about:profiles Opened profile folder Exit firefox transfer key4.db and signons.jstor files from backup to the new folder

Nothing happens.

I have tried creating new folders and following those steps. I have tried everything.

When I open any stream, it takes about 2.5 seconds from the start of the page loading to the appearance of the stream image and playback. For comparison, in version 137 it took about 1.0 seconds.

I tried to launch the browser (Firefox 138.0.1) in troubleshooting mode, and also created a new profile, but the problem remained.

I also downloaded portable versions: 137.0.1 - everything is fine. 138.0 and 140.0a1 - slow loading.

I also have Zen Browser installed (the latest version is based on 138.0.1) - everything is fine.

Most other forums don't impose this type of limited categorization. What is the best way to proceed here when you topic here doesn't have an obvious fit? This is not uncommon. Should I be concerned that my question won't get to the right eyes/assistance needed?

Some venues offer the ability to add tags. Why not give us the ability to add "tags" if you believe some sort of pre-designation is necessary? Does that qualify for my choosing this topic?

How about "other"?

Using 2025-04 Cumulative Update Preview for Windows 10 Version 22H2 for x64-based Systems (KB5055612) Firefox 138.0.1 (64-bit) and says it is up todate. I have looked at the about:config to find the browser.tabs.remote.autostart but it does not exist in the list of processes. I have also unchecked in settings both performance options intermitently to try and correct this problem, but nothing happens: (unchecked) Use recommended performance settings Learn more These settings are tailored to your computer’s hardware and operating system. (Unchecked) Use hardware acceleration when available Nothing pops up to allow choosing a different number as many support articles say. I have AdBlocker running as an add on and turned off the duck duck go privacy essentials and still nothing stops these insane amount of processes clogging up my computer. right now, on this page there is only this tab open and there are 13 processes running. Please send real fix instructions- thank you

For days I have been seeing Firefox be very slow to load a page (as in minutes) or stop working entirely. At the same time Chrome works fine. Mac Mail has become intermittent as well. I have uninstalled Norton products and changed Network proxy settings many times. Nothing helps. I have created new profiles. I switch between profiles. I have hacked into my WiFi router. Nothing, nothing helps. Safari hangs up too. Firefox on my android phone continues to work properly when using my Wifi router -the same router my Mac Studio connects to the internet with. I can access my third party mail service via Firefox on my android phone. Both FireTV devices work. I am at my wit's end. At this point I have shifted all of my work over to Chrome.

I have cleared caches. I have gotten rid of all cookies. I have restarted Firefox and rebooted my computer countless times.

Mac OS Sequoia 15.5 Firefox 138.04

while ysing the New York Times i tried to open the Athletic Section of the App and this was the result....Application error: a client-side exception has occurred (see the browser console for more information)....I cannot find information, can you help

Basically title.

Every time I close the browser and re-open it, the favicons disappear. I use the favicons to navigate to websites on my bookmark toolbar, but they're missing from my regular bookmarks, too.

I found an old thread that appeared similar, and the solution was to take a working copy of the favicons.db file and re-import it if it breaks (while the browser application is closed). However, this did not work.

Any help would be greatly appreciated.

Secure Connection Failed An error occurred during a connection to (Firefox and ALL sites) PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR Help advises 'Failed to check for updates' Problem arose on upgrade to Firefox 138 Tried restart, computer reboot and reinstallation

I am not sufficiently computer literate to understand supposed help and support documents within 'Mozilla Support'

It looks like the end of 20 years of using Firefox ... Google Chrome used to submit this request

Can you allow someone to get on my computer to help me? Or do you have a phone number I can call safely to have someone go through things with me, if I need help? It stated when I put it on that is is "poor" in terms of what you did. Maybe I am doing something wrong??

I am starting to use the new utility which allows me to group tabs. But I would like to see only the name of the group and not the whole list. How can I collapse the list of tabs which belong to a group leaving only the group name shown. Then with a click I should be able to see the corresponding list of tabs if I need it. Saving and closing a group is not a solution, as the group disappears from the Sidebar. Thank you for your help. Best regards Ray Ballisti [edited] @bluewin.ch Switzerland

The latest firefox update introduced tab groups, something I've been eagerly waiting for ever since chrome released it!

However, my firefox's tab groups don't hide the tabs correctly. In the video demo I see that when you click on the name of the tab group, it should collapse all the tabs and hide them.

In my firefox, when I click the tab group name, the tabs don't get hidden as expected.

Here is a video that shows the bug I'm referencing: https://imgur.com/a/8ewW1a2

I tried disabling all my extensions and restarting firefox, also tried in private mode, and it still was having the same experience.

Are there any about:config settings that I might have accidentally changed that could be causing this?

Thanks!

(This is copied nearly directly from a post on r/firefox made a few hours ago—I decided it was best to spread it here for more exposure. The only change was the removal of the add-on names from the title due to character limits; these are Form History Control and Text Area Cache.)

I hope the title explains what I am looking for well. My main computer has had... spooky behavior with its file system recently, and I have been recommended to make a back-up, format my drive, and re-install my operating system (possibly upgrading from Windows 10 to 11 in the process). The biggest hold-up to me doing so is this, as I have no idea how to transfer the extension data between installs, or convert it into a human-readable form. The sheer number of writing drafts in those extensions both make losing them an unacceptable situation and copying the data manually into a document entirely impractical. So, can anyone help me with this? For context, I was on Firefox 138.0 when I stopped using my main computer due to those issues. (Note: It will certainly last long enough to do the Firefox Syncing and other back-up operations, just not for many more weeks or months.)

Hello. For a while now I have been using the picture-in-picture feature to play a video in the corner while using other applications. It has been a great help as I have a single monitor.

Unfortunately, I have recently been encountering a severe issue with the feature over the last week. When attempting to use picture-in-picture while my computer is running a videogame (through Steam) my entire system will freeze. The audio still plays as normal, but the image is frozen and the system is unresponsive until I force a shutdown and reboot.

Any help at all in with this issue would be greatly appreciated, thank you.

Logs out of email (gmail) after restarting the browser. I reinstalled windows and downloaded a browser, connected my account, and now when I go to gmail.com and register my mail, everything is fine, it works, but when I exit the browser and go back to gmail.com, there is nothing.

When I play games like classic.minecraft.net or krunker.io, the pointer speed is very slow. So I would like to know if there is a way to change the pointer speed of firefox.
