Hii. Amazing browser tho, whenever i pin something on top or chuck it into essentials - when i close that tab - it disappears (and reappears on browser restart) - i could not locate any setting pertaining to essentials that would stop that behavior (ideally when i close the pinned/essential tab i would love it to stay there as a bookmark - anyone know of a way to achieve this?

Microsoft seems to have cut Firefox out for video chats. This is a recent change. Their message is that video is not supported by my browser (Firefox)

I submitted a question earlier about not being able to use DocuSign. jonzn4SUSE was very quick with a response that worked perfectly. However, when I tried to mark it solved, I got the following error message. In addition, I didn't know where to find my original question so I could thank Jon and mark the issue closed. Where should I have looked for it?

Looks like there’s a problem with this site

I found this file on my desktop. File type is Firefox HTML Document. Size 1KB. I've never noticed this before and wonder it I should delete it, move it, or what. Anything to worry about? I haven't opened it.

Thanks for any enlightenment you can offer!

I read a SmartBlock explanation, but it was quite unclear. Seems to be tying SmartBlock to Facebook. I do not use Facebook. Why is logging in with Facebook required for SmartBlock to work on sites that are unrelated to Facebook? Very unclear.

Many web sites have a dark colored box around selections, such as an option to show orders. They are currently shown in purple, which is almost impossible to see against the black. I've played around with the contrast and font settings, but haven't found a way to solve the issue--right now I'm just living with it. Any help would be greatly appreciated.

bookmark bar and all my bookmarks are gone I followed Support instructions, clicked on Manage bookmarks and went nowhere. I really need this function to work as I am sight impaired and can't use my phone for much. Please help.

I tried to add the roboform browser extension twice and I get the following message (the second time was from the Roboform homepage):

Installation aborted because the add-on appears to be corrupt. Preview of RoboForm Password Manager RoboForm Password Manager by Siber Systems Recommended

I have suddenly lost all my Bookmark Tabs. I have followed instructions on restoring them, but I only get as far as Import and Backup. The Restore button only gives me Choose File. When I click on it Nothing Happens.

I have a problem. When watching videos on YouTube, especially in 4K, it starts to freeze, and the loading screen stays on indefinitely. The same thing happens when you fast-forward or rewind the video. Switching the video to 1440p or 1080p helps, but over time, even at 1080p, it starts to freeze. but if I switch back to 4K, everything works fine, but only temporarily or until I fast-forward it.

I can provide browser data files. I'll say right away that I've tried a lot of things, and even everything that ChatGPT recommended didn't help. I tried changing the about:config settings related to the video player and codecs.

The only thing that helped was installing a plugin (h264ify by erkserkserks) that disables av1, and in that case the video works fine, BUT only at 1080p, which doesn't suit me, as I would like to watch videos in high quality.

If I disable hardware acceleration so that videos are rendered on the processor, then everything works fine and everything runs smoothly, except that the processor is loaded at 60%. This may be a solution to the problem, but I would like to figure it out and solve it completely, rather than looking for a compromise.

Motherboard: ASRock B850M Pro-A (BIOS date 02/21/2025, DMI BIOS version 3.20) CPU: AMD Ryzen 5 8400F 6-Core Processor RAM: Crucial CP16G60C36U5B (Crucial 2x16 - 32GB) Video card: NVIDIA GeForce MSI RTX 3080 Ventus 3X OC LHR (MS-V389) (Driver version: 32.0.15.7652, Development date: May 14, 2025, DirectX version: 12 (FL 12.1)) Video card driver 576.52, May 19, 2025 The entire system and browser are installed on an M.2 NVMe CT1000P3PSSD8 SSD (Crucial P3 Plus 1TB PCIe 4.0 x4) (there are also other drives) (2 monitors 1440p) Windows 11 Pro If any data is required, I can provide it. All drivers and everything else are installed in the latest version (unless new ones have been released or it has not updated itself). All Visual C++ and Windows components are installed, I don't think there is a problem with them.

The problem only occurs in the Mozilla browser; there are no problems in any other browsers. I also noticed that on some websites where I watch movies, there is a problem with the video. Unlike YouTube, they load normally, but in dynamic scenes, the image breaks up, similar to the image breakup in games when vertical synchronization is turned off. That is, the video is divided into two parts, and one of them lags behind by a fraction of a second. I tried resetting the browser settings, but it didn't help. Everything works fine on my MacBook and in other browsers and devices, so it's not related to the internet.

Please help me figure this out and solve the problem because I've already tried everything, and I don't want to switch to another browser because I've been using Mozilla for over 15 years. Also, if you need any information or a detailed explanation, I can show you or even record a video. Everything worked fine on Windows 10 on the same system, but Windows 11 is not running as smoothly. (To clarify, this is a clean system; I did a complete clean install of Windows 11, although when I upgraded from 10 to 11, everything seemed to work fine).

I would be grateful for any help.

The recommended methods, changing to this in the registry :

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox\Certificates] "ImportEnterpriseRoots"=dword:00000000

Reverts back to 00000001

Put this policies.json and did nothing: {

 "policies": {
   "Certificates": {
     "ImportEnterpriseRoots": false
   }
 }

} What am I missing or what's changed?

My specific need at the moment is to add another search engine option in about:preferences#search

Thanks.
