Firefox Community Forum

[edit] I was using my phone to post this question and inadvertently posted it to the android forum. This is a DESKTOP question.

I'm trying to sync my tab groups across my desktop/laptop. I have sync enabled through the settings and I've checked every box, but I don't seem to see an option for syncing tab groups specifically. It syncs all of my bookmarks and active tabs, but the groups seem to be unique to each device. Is this feature available? I might be looking in the wrong spot so if anyone has any insight that would be great! Cheers

I am trying to change my browser from Chrome to Firefox. I am having trouble importing bookmarks etc. When I select the versions to import, only one option from Chrome is displayed in the list - it's the version/setting of SOME years ago. What can I do to import current bookmarks?

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.

I'm not sure what's going on here, but speaking to different people, I hear different stories.

I use FireFox and have PiHole installed on a RasPi. REMOTE ACCESS.

There is a window - to call it - where I can enter any fixed IP addresses.

I can only open it a bit (height wise) but am being told it can open a lot more.

I've tried FireFox and Opera. Both don't allow it to open much more. (So really I don't think it is a Firefox problem)

Anyone have PiHole installed?

How "big" can you make it?

When I launch the browser, can I not preload tabs that I have not used yet in this session, but which are open from the previous one? This is slowing down my weak PC. I did not find anything about this either on the Internet or in the reference book. Thanks in advance for your answer

Firefox just introduced a cool feature that lets us set custom wallpapers on the home screen—love it! But whenever I try using pictures from my personal library, they don’t fit properly and end up getting cropped. Resizing doesn’t help either, since making the image smaller just ruins the quality.

So, is there a specific format I should be using? Like, does it need to be JPEG only, or will any file type work? And if any format is fine, what’s the ideal one for the best results? I couldn’t find anything in the settings or help pages about this.

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

Hello,

Recently noticed how browser changes the language on restart from English (default language ) to Russian. The affected websites swapped interfaces to Russian language.

Is it part of some kind of A/B testing, locally distributed malware / spyware or just simply embedded ML ops?

I am using macOS.

Thank you, Kind regards, Dmitrii.

1.The browser is closed 2.Looking at the task manager, there are still two browser processes (firefox.exe) present and they together take up about 3GB of memory 3.These two processes have no I/O reads and writes. 4.These two processes cannot be concluded. I've tried CMD, Powshell, XueTr, etc., but none of them can free up the memory space occupied by these two processes.

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.

I got the above mentioned prompt in prime video and the first thing I did was to rush here and check if anyone else had the same issue and a lot of people did, but the solutions that were provided underneath their tickets didn't seem to help me.

I tried everything, clearing cache and cookies, refreshing firefox, reinstalling firefox, but nothing helped, the same issue was occurring on the firefox app from MS store. I reached out to prime video's customer support but after few weeks of back and forth communication, they put their hands up as well. But they did inform me that "HD 1080p" which used to appear at the bottom left of a video has been removed due to unreliability.

It was one of my reference points to check if a video is actually running at higher definition along with the "Good, Better & Best" in the "Settings" option. But strangely enough it still shows 6.84 GBs per hour in the Best option which it does when a video is running at higher definition.

The prompt has thrown me in multiple directions, can anyone PLEASE HELP ME! I'm going crazy

Hi, as the title says, they stopped displaying after I installed the latest update for firefox for my computer (macbook air with the apple M1 chip). I have checked that in the settings I have "Show an image preview when you hover on a tab" enabled and that in my config I have both browser.tabs.hoverPreview.enabled and browser.tabs.hoverPreview.showThumbnails set to true. What could the issue possibly be now?
