Firefox Community Forum

Hello,

I'm writing because I’ve encountered an issue with the tab groups feature in Firefox.

Some time ago, after a browser update, I noticed a new feature that allowed me to group tabs thematically — I could name each group (e.g., "Study", "Work"), choose a color for it, and save and close groups to reopen them later. I found it very useful and used it a lot.

Last night, I decided to declutter my browser and closed several tab groups using the built-in menu. A bit later, I shut down my computer, but perhaps too quickly. This morning, when I turned my computer back on, Firefox was very slow to start. After a restart, everything seemed to work fine again, and the open tabs were restored.

However, all my previously saved (but temporarily closed) tab groups disappeared. In the tab group menu, I can now only see the ones currently open. I’ve searched through all the settings and history but cannot find any way to restore the missing groups.

Is there any way to recover the tab groups that I had previously saved and closed?

Thank you very much in advance!

I recently ported from chrome to firefox about 3 days ago and was tryin to access the dropdown menus on this website https://www2.gov.bc.ca/gov/content/governments/government-id/bc-services-card/your-card/get-a-card

I realized it wasn't working so I turned off my adblocker (ublock origin), refreshed the site and still not working.

Also attempted to use troubleshoot mode and still does not work.

Cleared cache + cookies and used troubleshoot mode and nothing working still.

I lastly checked the website was working by opening the same link on chrome after all that and it works perfectly fine over there. Any ideas what could possibly be the issue?? I basically have a fresh install of firefox with no changed settings besides anything that might of been copied over from Chrome when firefox automatically asks you to migrate your stuff over, and used the troubleshoot mode + clearing cookies and cache

I don't know what you're doing but EVERYTIME I do an update lately, something goes wrong. Today after update, my STGs are affected and ALL ARE GONE. I do NOT believe this is their fault. And you put this dang auto Startpage when launching window, I did NOT ask for that. I am so pissed, how do I get them all back? I had things I was working on that were very important. What else did you add to FF that I don't know about? I don't want your updates anymore. You screwed me big time. And I don't want the extensions YOU think I should have: Google, eBay, Bing, etc. wasting my space. I'm not the only one either, seen lots of complaints.

HOW DO I GET THOSE TABS BACK??????

I received this download from Firefox today, July 22, 2025: xRqj7qhl.html - Size: zero bytes - Kind: HTML text . I've never experienced this before. Is it legitimate? Thanks

Hello, FF support forum,

I think I have seen a Container retain my login to a site when I open it again after closing it. Is there a way to configure Containers so that they are mini versions of the dump-cookies-temp-data when I close Firefox entirely? I would so love that functionality.

Regards, G.W.

I was trying to setup 2FA on my Mozilla account on Firefox pc browser (140 version). The process completes without issues with Aegis authenticator app, I download the backup codes and I even get the email confirming the recovery phone number was added. On the Mozilla accounts page 2FA turns to enabled. (I'm on Windows11 with latest Firefox browser version)

However after a simple refresh, it turns back to disabled. I repeated the process and same thing happens. Same even on Firefox Android. What could be the issue here?

How in the heck do you increase the size of the UI font? I have a 1440P monitor and the TINY size of the UI font makes it nearly impossible to read the text on the menu buttons, I have lean forward and squint to read it because they are so damn small. I can't find anything in the settings to make the UI text larger. It is as if some dummy hard coded the UI font size so it's impossible for the average person to find out how to change it. It makes no sense whatsoever.

And please don't tell me to increase the zoom in the Windows settings, because that screws up EVERYTHING else...

Another thing that is driving me crazy is how do you set it so that scrolling with the mouse wheel is smooth and not jerky? When i scroll with the mouse wheel, instead of smoothly moving the page up or down, it JERKS a couple of lines at a time. This is the only browser that it does that in. I have smooth scrolling ON in the mouse settings on my computer but for some reason, only Firefox is doing this.

I am using version 140 on Linux and now two company sites do not work properly when "enhanced trakcing protection" is enabled. The 2 companies are "public mobile" a Cell phone provider and "Voip.ms" a phone provider.

When I log onto public mobile I cannot view my specific account information, I can see other menu information. voip.ms I cannot log on either chat or the main customer portal. This only recently changed within the last 4 days and I am using the same version of firefox.

Can you provide an explanation as to why this is occurring?
