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?

I really REALLY don't like tab buttons

How can I make sure they NEVER come back ?

I have tried the violentmonkey script, doesn't work, I have it right now and look, there are TWO tab buttons on my tab !

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

Hi,

I had 11031 tabs open. I decided to save all of them because my browser was getting slow.

Just running "select all" was taking minutes, and resizing the window was very very sluggish.

So I selected them all

(screenshot 1)

then I added them to a bookmark folder

(screenshot 2)

Then I went in the toolbar where that bookmark folder was created, and I middle-clicked on it to open all tabs again.

(screenshot 3)

And then the warning "you are about to open X tabs" appears

(screenshot 4)

And the problem is that the number is 8571 not the 11031

Why is firefox losing 2460 of my tabs ?

Also, bookmarking all the tabs, took 4 seconds, while selecting all tabs too minutes. I think the "select all" function could do well to have some optimization as it starts getting slow with as few as 1000 tabs. And

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

Since I upgraded from FF128-esr to FF140-esr I always get the "Firefox is being updated by another instance" This is really driving me crazy, as I checked / did / .... everything (and even more) I found on the internet related to that.

Nothing helps !

Creating and using a new default profile didn't help

Finally I ended up uninstalling FF completely (making sure no -zero- leftovers remained in ProgramFiles, AppData a.s.o.), and reinstalled FF140.7.0-esr freshly. After installation I started FF immediately with the created default profile (only existing one) --> SAME THING : "Firefox is being updated by another instance"

And this is really a FF140 thing, when I go back to FF128, on the same computer, same profiles, ...., the problem is gone.

I would like to know in detail what checks are really done by FF to decide to give that "Firefox is being updated by another instance"

Firefox was updated. I was Hacked. Now I cannot log into my email Provider. Firefox is my default browser. How do I access my email provider via firefox browser now?

All the application windows I had opened on my Mac, closed due to a security related update. Now Firefox isn't showing any of my tab groups from before and also there's a weird behavior when you click on the Firefox icon, it opens a new window that is small, but when you do file > new window it also opens a window but full sized. I tried creating a new tab group and the second approach of doing file > new window is showing the tab group in the tab group menu, but the window created by doubling clicking the icon doesn't show it.

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.
