My tab groups just got lost. I didn't do anything to remove them. How can i restore them?

When this feature appeared, it was not available to me and I included it in about:config, but them disappeared when this feature reached me officially.

I wanted to create two profiles to separate my work and personal contacts. For security reasons, I also wanted to set up one account as the secondary email address for the other (I only have these two email addresses). Account A is a Gmail account and Account B is an enterprise domain account. Account B had the Gmail account as the 'secondary email'. However, when I try to access the Account A profile, I receive a red square message saying 'Primary account email required for sign-in' after entering the password. Perhaps I did something wrong, but... How can I access my Account A profile? Account B no longer has a secondary email address to prevent further problems.

Hello Mozilla Community, Every time I want to log in to Samsung.com and eu.community.samsung.com/t5/deutsch/ct-p/de, I have to re-enter my email address. The password is suggested. I'm not asked if I want to save my login credentials, but I'm asked for it on all other websites. I prefer Firefox to EDGE (it's suggested in EDGE). It's like this on Windows 10 and on my other computer with Windows 11 (both 64-bit and both up to date). What do I have to do so that Firefox also suggests the email address on these sites (asking whether it should be saved)? And I use a translation program from German to English. Again, thank you in advance for your reply.

I have downloaded Duolingo on my Windows 11 laptop. When I try to run it, it says that it can not open it because it can't find Microsoft Edge. This is the latest version of the app. I can't find anywhere to change the Duolingo default browser. I have Firefox set as MY default browser in windows settings. I also have AVG Secure Browser installed on my laptop but seldom use it. I donot have MS Edge installed on any of my computers. Can anyone help me find a solution to this problem? What other information do you need?

After last upgrade, I restored an earlier profile to RESTORE my bookmarks and passwords.

I set my old profile as DEFAULT.

YET NOW, I have the highly annoying problem that when I open a link from my email, it opens in the profile-release new version.... I then again do not have access to passwords and bookmarks.

Mozilla Firefox should address these issues, rather than have MILLIONS of people individually trying to fix the problems that the latest release caused.

I'm afraid to close my browser windows or even restart PC like I often do; I'm afraid I'll have to waste another 6 hours (like yesterday) trying to restore the profile, bookmarks and passwords.

The Firefox version I used before was Mac version 136.0 After I updated to the latest version, I found that the fonts of the browser's tab bar, search box, and bookmarks became significantly larger. How can I change the font size?

[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'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?

Settings/DHCP (expert level) Scroll down to Static DHCP configuration.

The window where you enter addresses.

How "big" can you make i

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.
