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 opened a profile that I had just used recently to a blank tab bar. I closed it and the sessionstore-backup folder did not have a recent backup, The most recent about a week old.

Just for testing, I tried to restore with one of the upgrade.jsonlz4 file, about 2 weeks old, but it also had no session. I then restored one that was 2 months old. That one had a session

Now, Firefox no longer generates the upgrade.jsonlz4 files

Sometime ago I must have made a typo when entering my email address into a pop-up window in Firefox. Firefox continues to find and use this wrong address in pre-fills but I can't find anyway to correct it. I've worked through Settings/Privacy & Security with no luck. Can someone help please? (Windows 10 Firefox 145.02)

Just recently I am no longer able to login to the discover.com site in private mode. It still works in regular mode. I'm using this on a desktop, not the discover app. I spoke to their tech support and tried to do a login while on the phone. They told me nothing was coming through on their end. So, what changed and how can I fix it please?

Dzień dobry Mam otworzone strony Facebook i Mesengera.com w przeglądarce i nie mogę wykonać połączenia wideo i dzwonić do osób prywatnych, na grupach to działa. Natomiast do osób prywatnych nie podświetlają się ikony telefonu i kamery i tym samym nie mogę się połączyć, jak to naprawić? W Chrome działa. Dzięki za pomoc.

When I attempt to log into my ssa.gov account thru either login.gov or id.me with firefox browser i get the following message. "Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit." I can access both with google or edge. I am running windows 11 with most recent firefox update What do I need to change in my firefox settings?

Hey I changed my password before reinstalling the Windows but when I reinstall Firefox and logged in, all of my information was gone since Firefox doesn't back up after password change so I uninstalled Firefox since then because it was useless to me. I was looking through my files and I find that I still have the previous recovery code before changing password, can it be used to recover my passwords and bookmarks?!

Since update to version 145.0 I cannot send messages, when sending I get this message "Sending of the message failed. An error occurred while sending mail. The mail server responded: <*******@shaw.ca> sender rejected AUP#POL. Please verify that your email address is correct in your account settings and try again". Nothing has changed with account settings. Same problem on another machine that updated to 145.0. Any ideas what is broken?

I was googling something related to my game and i clicked on a Reddit search result, which i made sure is the official Reddit website not some shady one, then an empty .htm file from moz-safe-about resource got downloaded randomly. I didn't open it, i uploaded it to VirusTotal which came out safe and then i instantly deleted it and ran a virus scan with Windows Security which also came out clean. i tried to recreate this by opening the same website again both on Firefox and other browsers like Zen(Firefox based) and Chrome but nothing happened.

is this a harmless bug or should i worry that it could be a virus that didnt get detected?

its pretty much what it says on the tin, im not seeing my channel points in chat

 i have turned off all the tracking stuff 

i turned off the enhanced tracking and i still cannot see or earn my channel points i have turned my site security to nothing to see if that would do anything I have turned off all my add-ons and they just dont show can anyone tell me whats happening here

Please can someone be kind enough to assist me. I cannot seem to log in as normal and therefore cannot get my emails and therefore are not able not reply to them.

Doing a "find" ends up showing a greenish (so I'm told) background with white text. Want to guess which "find" in the attached image is difficult for me to find?

What I would like: Find (focus): yellow text on black background Find All: white text on black background

Yes, of course it would be nice if that would auto switch to black on yellow if the website default is black background.

I can hack userContent.css and get the selection function to work:

/* General highlight (for text selection, etc.) */

selection {

   background: #FFFF00 !important;  /* Yellow background */
   color: #000000 !important;       /* Black text */

}

I can hack userContent.css and get the Find All (sans the focus) to work.

But firefox always provides the focus with white on green. Even if I do something like this:

/* Customize the color of highlighted search text */ input[type="search"]:focus::selection {

   background: #FFFF00 !important;  /* Yellow background */
   color: #000000 !important;       /* Black text */

}

I tried several themes. No change. I tried changing Windows Preferences. No change.

There must be a way to make this "find" feature useful for me.

When i try to insert a screenshot through the clipboard on google or yandex image search, the original image is corrupted. Even i try to upload an image via classic upload-button the same problem reproduise. On other sites there is no similar problem, as well as trying to insert the same image but inside the application windows.

In attachement: yandex/google and default image i was trying to upload.

When I went to my Firefox password page there was a red banner saying my website was hacked and my passwords stolen a year ago. That message was not on that page a month ago. Please advise urgently.
