Every time I change the settings in the image attached, once I close the browser, the settings are reversed back. My changes do not persist if Firefox closes or my PC turns off. My other settings persist when I make changes. I only get this error when I try to edit the Privacy settings.

What is causing this, and how can I stop it?

Windows 11 Home Firefox up to date with 140.0.4 (64-bit)

Old computer crashed....so lost all my bookmarks and their folders. Now in Windows 11 and I can make bookmarks for my Fox toolbar but I can't find where I can created folders for my bookmarks. Can I still do it and if so how?

Hello,

I'm experiencing an issue with YouTube video playback in Firefox. When I watch a video in Picture-in-Picture (PiP) mode and then close the PiP window, the video automatically pauses on the main tab in the browser.

My expectation is for the video to continue playing in the background tab after the PiP window is closed, similar to how it works, for example, in Opera GX browser.

I have already tried changing the media.videocontrols.picture-in-picture.pause-on-disable setting to false in about:config, but this did not resolve the issue. The video still pauses.

I believe it would be a significant convenience if Firefox allowed videos to continue playing in the background rather than pausing them when the PiP window is closed.

Is there any way to fix it?

Hi Mozilla Community,

I’ve been experiencing some issues with video playback on Firefox, specifically on YouTube. Videos seem to always play in a choppy manner, no matter the quality settings. I’ve tried clearing the cache and updating Firefox, but the issue persists. I’ve also checked my internet speed, and it's stable, so I'm not sure where the problem lies.

Has anyone else faced this issue? Any suggestions on what might be causing the choppy playback or how to fix it?

To give some context, I was also recently looking at how efficient high-speed trains operate around the world, and came across a fascinating comparison of the top 10 fastest trains in India. Just like video streaming, maintaining high performance and smooth operation is key — it made me realize how even small optimizations in streaming might have a big impact on the experience.

I appreciate any help or insights from the community!

Thank you!

Is there a way to permanently set sorting from A-Z? When I open a file & go to site, I then have to reset sorting within the folder when I go back. Using down arrow sends me to the next folder. Have been Mozilla user for decades but didn't open account until recently. Always set to my default, even on latest PC, in conjunction with other programs. Don't like Microsoft programs.

Guess I probably owe Mozilla a donation but have tight budget, as Sr. on Social Security. Maybe I can contribute a small amount if that would help?? Don't want a subscription. Can't afford it.

Hi - Firefox placed an 'Old Firefox data' folder on my desktop and I am unable to delete it. I'ver tried third party apps, logging in as administrator, command line delete, uninstalling FF but am still stuck with it and my network settings are wrecked so I can't re-establish connection to the internet on that machine. Anyone with any suggestions as to how I get rid of the 'Old Firtefox data' folder ? Many thanks...

When I click a link I always want it to open in a new tab. How do I do this without doing a right-click and selecting "Open in new tab"?

I want it to open in a new tab when I simply click the left mouse button.

Attempting to bill pay at Allstate page, stating the browser is not compatible. What options do I have? I have been using Firefox for > than twenty years, I have a hard time trusting anything that comes from Microsoft after their internet explorer debacle .

So when I open some websites such as the RimWorld wiki ( https://rimworldwiki.com ), whenever i scroll my gpu for firefox launches straight to 100% and becomes extremely laggy. I have no idea what is causing this. My friends and other browsers run it completely fine. I have tried troubleshoot mode, gotten rid of all my extensions and themes, removed all cookies and cache and nothing works. My drivers are all updated, and I have truly just given up. If anyone has any solutions I would be much obliged.

Hi,

Not sure if anyone else is reporting this but ever since the last update - 140.0.2 Firefox Release, June 27, 2025 - many of my general sites, yahoo, news, company sites that I use everyday, do not load. I have to use Private Browsing, keep refreshing or change URL for the site to load. Anywhooos, I do appreciate you guys! keep it up!

who would recommend to install Firefox and get it ready for general use in the 48346 area code? We had BRAVE recommended & installed and it is not user friendly. We want to return to Firefox,

With vertical tabs and expand on hover, clicking on the X box rarely closes the tab. Sometimes I have success if the pointer is on the left or right line of the box. Not having luck on the center of the box. Has been true for several weeks. With hover off, clicking the X works fine. I am running Windows 11.
