Firefox Community Forum

Hello,

I apologize if the topic is incorrect, but I didn't know which applied to my situation the best.

Starting on Monday of this week (4/28/2025), YouTube no longer loads properly on Firefox for me. The entire page is covered in video slots with no videos and if I try using a link to a specific video, it will take me to the page, however the video will not load or play, additionally any other elements such as comments or suggested videos will not load. I am using the latest version of Firefox Developer Edition.

I have tried all of the following:

• disabling all of my add-ons
• clearing cache, cookies, and history
• uninstalling and reinstalling Firefox
• logging in and out of YouTube
• Reaching out to YouTube (they told me to just use Chrome)

I have asked my friend who also uses Firefox and YouTube works fine for him, so I'm not sure exactly what is making it not work.

Thank you for your time!

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"?

This question is about a specific Firefox add on. I have not used extensions or add ons previously and am concerned about the safety of the one I want to upload: Claude Conversation Capture.

The page says it will require permission to Download files and read and modify the browser’s download history (which is fine) and Access your data for all websites (which scares the heck out of me.)

How can I safeguard my privacy and data to prevent a breach and maintain proper security if I download this add on?

Can anyone help with this please? The add on would be extremely useful but not at the expense of my security and privacy.

FWIW I am #notageek and very tech challenged, so please explain anything I need to know in ordinary language I can understand (will be greatly appreciated.)

Thank you!

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...

Due to not everything reloading every time, a connectivity problem I can't blame Firefox for, I now have 3 windows, together comprising all the tabs I want [OK some are duplicated, but it's easy to remove those...]. How can I stick those all back into one window? - with my pinned tabs at the head., which is where they were before...

Hello people,

Please some help around the following issue, since a few days, Firefox will not play mp4 files directly in the browser. What it does when clicking to open an mp4 from the file server, it saves the file first and then opens a window to play it. Or it directly provides the save dialog window instead of playing it in the browser window directly.

Any ideas, appreciated. I have a lot of files to assess for my students, and this browser behavior makes it very tedious.

Greetings.

Hi. There is a new feature of Firefox that bothers me. It is when I drag tabs around the top, they try to group when I don't want them to. So I go to about:config and find the "browser.tabs.groups.enabled" key and set it to false. But when I restart Firefox, the change reverts. How do I fix this so the change stays?

I've already tried going to Menu->Help->More troubleshooting information->Profile Folder->Open folder, but there is no "user.js" file there. Do I have to do a Firefox reset to fix this? I hope not...

Note that I'm pretty sure that other settings that I change do not revert when I restart Firefox. Right now, it seems to be just this one about:config setting, unless the new version of Firefox reverts all manually changed about:config settings upon restart.

Thanx in advance for any help.

WHY HAVE ALL MY SAVED BOOKMARKS DISSAPEARED ??? THERE USED TO BE A COLUMN ON THE RIGHT WHEN I OPENED THE BROWSER, ITS GONE. I COULD CLICK AND GO TO THE SITE I NEED TO WORK WITH ??

When watching videos, switching between my Bluetooth headphones and Mac speakers will cause the sound not being able to output correctly, the video will be seem muted. Sound output is fine when using other explorer and apps. Restarting Firefox will usually fix the problem.
