I rely heavily on tab groups to organize my browser sessions for different tasks and projects. I’ve experienced an issue where, after saving+closing tab groups, they disappear from the “Recent Tab Groups” section after some time. This means (EVERYTHING IS LOST) I have to recreate my organized tabs from scratch each time, which is a "significant workflow disruption" (to say lightly). I understand tab groups are designed to persist across sessions and the hinting fox menu says they should be available for reopening in “Recent Tab Groups” at anytime, but I’m finding this isn’t consistently working (on several devices I use). I’m hoping to understand if there’s a limitation or known issue with how tab groups are stored, and whether there’s a more reliable way to preserve these groupings long term. It’s possible others are running into this behavior too, and I’d appreciate insight into whether this is a known issue or if I’m missing something in how tab groups are managed. Perhaps a future patch could address this persistence problem for long term reliability?

Hello,

I've been using the profile manager, and wanted to delete a profile that i have made. However, when i select the option to delete it, it only opens up a new tab in the profile called "about:deleteprofile', which displays an empty page and does nothing. Then, I would try to delete the profile manually, in the profiles folder, but if I opened firefox or restarted my computer, it would just come back. I have attatched the relevant images below.

Why isn't the customization layout being maintained in the sync?

I use Firefox on one computer, and when I opened another computer, installed Firefox, and logged into my profile,

the bookmarks appeared (but without icons).

The add-ons also appeared, but they were all hidden in the add-ons list.

I have to rearrange them and pin each add-on individually to the browser's top bar to be able to browse and access other icons like (Settings, Library, and the Home button).

This is a waste of time and effort and very annoying. The customization layout should also be synced.

I keep losing all my saved passwords in my Firefox browser when I get a Windows 11 update, Why and how do I recover them and prevent them from being deleted when there is Windows 11 update? thank You

on other webpages a black bar drops down from the bookmarks bar and blocks the top of the pages, how do i get rid of it? oddly on this page, the bar does not show up

j'ai restaure w11 en supprimant tous les fichiers, puis mise a jour mon compte mozilla qui avait 2comptes 1 perso et 1 pro, pour mettre a jour a 1 compte par session pro et perso et éviter confusions ,j'ai certainement fait une mauvaise manip et je ne retrouve pas mes marques pages et mon organisation . puis je retrouver ces marques pages ???? en me reconnectant a mon compte initial et resynchroniser pour info le mot de passe du COMPTE PRINCIPAL MOZILLA a été changé car les 2 dossiers qu'il incluait avaient la même adresse mail . pour faire simple :

COMPTE PRINCIPAL MOZILLA  : cccc adresse gmail mdp : xxxx123

dessous  : compte PRO  : cccc adresse gmail mdp : xxxx123

dessous  : compte perso  : JJJJ adresse gmail

je pense avoir tt essaye , vu que j'ai restaure w11 et supprime les fichiers je n'ai plus l'anteriorité , le fait que j'ai change le mot de passe du COMPTE PRICIPAL DE MOZILLA a du ecraser les donnes . qu'en pensez vous avec mes remarciements

Recently, after I did a practically factory reset (using the restore from other device option once the system restart finished) and re-installing many apps, such as Firefox, despite my computer getting faster my Firefox now lags whenever I have Youtube running in the background (audio or picture-in-picture, both lag) at least during gaming. I have tried disabling GPU acceleration, with no luck, and have tried utilising picture-in-picture, which also failed. I'd appreciate any help on solving this.

All the icons in my Bookmark Toolbar have been working great with no errors for several years, through countless updates with no problem. Then, recently I noticed all the icons lost the color icons and just show as a wire globe. Clicking on them, any one of them, they all go to the same website. If I remove them, got to the website I want there, and drag the URL to the bookmark bar, things are back to normal for that icon. So I replaced each one, and the next day, when I open Firefox, all the icons are again wire globes. It seems that Firefox will not retain the URL for any of the icons.

Very strange.

Lost Mozilla as my default browser after accidentally opening my Facebook page using Edge. The only site that is corrupted is Facebook. All others work properly. I still want Mozilla. Looks like I've created a newer Mozilla account even though I used my password to open my account using my email address and password. My profile name has changed. Wondering if problem occurs because account is shared with my husband and our account is under his name/email. Any suggestions appreciated. We do subscribe to Norton. Thanks.

I've recently begin to receive pop-up notifications from Facebook, but when I choose to stop them, it doesn't. It takes me to Facebook and the notifications keep coming. How do I stop them?

After moving to a new laptop my Mozilla appearance changed drastically such that often the text is invisible (sometimes clicking on "select all" is a sub-optimal workaround".) Some images are blank spaces. I've tried working with "Website Appearance" in the settings to no avail. Thanks for your help!

For the last 2-3 day I have been experiencing a box that asks for my signature each time I go to a new website. I can't move the box. I can't screenshot it. Does anyone know how I can get rid of it?
