Firefox Community Forum

Anyone have any idea why after five minutes on any and all sites, Mozilla shuts it down the tab (leaves the site, ) and returns to the opening screen? (I'm using Windows 7 and my Firefox browser is up to date). Thank you for any assistance...

How can I move a tab to an open window? I know there is a function in the pull down menu to open the tab in a new window, but I would like to move the tab to a window that is already open. Google and Brave Chrome have a seamless, easy way on the pull down menu. I use it all the time, but I want to keep Firefox as my default browser. Thanks!

In early June 2025 I finally ditched Windows 10 for 11 and I've been a Firefox user since practically the very beginning of Mozilla.

Now, I notice that the "Restore Previous Session" button in the drop-down of the FF menu is missing. Additionally, I discovered late in the game that Mozilla DID listen to me and gave us the ability to "name" or "tag" an entire window in the browser. This was a HUGE boon to productivity as I'm constantly toggling from window to window to tab to tab.... Now, with the most recent update this ability seems to have disappeared....

I have the most recent update and have been excited about tab groups, but it's still not working on mine. I thought the update would be available to all as of May 6, 2025. Is this happening to anyone else?

I'm on the latest FF 140.0.1 on Linux and I adore tab groups, I'm using it more and more to organize my browser windows. I am using the default (horizontal) tab group layout. Because I have a lot of tabs in the window, I collapse each existing tab group and sort tabs between tab groups.

I can move a tab into an expanded tab group with drag and drop. But I tried dragging and dropping a tab onto a collapsed tab group, even holding it over the collapsed tab group to see if that would work. Nothing seems to register, is it possible?

I would like to move a tab by drag and drop without expanding the collapsed tab group and move the window focus to the next tab. This would save time when I am organizing tabs!

The alternative is to Add a tab to a collapsed tab group, which also expands it and consumes horizontal real estate, forcing me to scroll (further) to return where I was organizing tabs. So I collapse the newly expanded tab group, scroll back to the next tab I want to organize into a different tab group, and repeat but this causes a lot of scrolling navigation to my workflow. It makes complete sense and I really like using menu navigation to add tabs to a specific group because it is discreet and I wish I could move tabs with the same method.

I searched Settings > Tabs and then about:config for browser.tabs.groups.* (and then every preference with tab in it) and couldn't find anything that made sense to me.

Thank you for any help!

So far I have accumulated a dozen windows and each window has 1-10 tabs. I would like to be able to see a comprehensive list of all my open tabs and to be able to click on any one. Is there a way?

I really like the new tab group feature and I wondered if it would be possible to isolate tracking within a tab group. I didn't know about tab containers yet but it seems like a great feature to have the option to have a tab group also act as it's own tab container.

Are there any plans for integration between these two features?

Hi,

I started using the 'Vertical tabs' option to manage my tabs. I prefer it over the horizontal bar. However, I noticed that when going fullscreen (F11) the vertical tabs are not removed. This is different from horizontal tabs, which are removed from the UI when you press F11.

I think that's because vertical tabs are tied to the sidebar altogether. Is there an alternative to have the vertical tabs work the same as horizontal tabs?

Horizontal bar behaviour in fullscreen:

- The horizontal bar disappears when going fullscreen (F11) - The horizontal bar reappears when hovering the mouse over the top of the screen (which is great!)

Vertical bar behaviour in fullscreen:

- The vertical bar does not disappear and gets in the way of the fullscreen (F11) experience - Checking the setting "Expand sidebar on hover" does not replicate the behaviour of the horizontal bar reappearing upon hovering the mouse. Instead, the smaller version of the sidebar remains and it expands to it's full size when the mouse hovers over it - The only option is to remove the sidebar altogether, which means going back to horizontal tabs

Can someone tell me why it is if I'm on a tab and either accidentally or on purpose click the home icon the tab will shut down, and be replaced by the home page? What type of backwards reasoning went into that feature? I've had this happen numerous times without intent, and sometimes with the intent to hit the home button and either way the same thing happens. If it weren't for the browser keeping a history, there are times I would be just out of luck, and have to suck it up. This is not a feature I want in a browser. Instead hitting the home button should forward the tab I'm on to the home page with the ability to back click to the tab I was on. Someone needs to re-think this feature. I would really like to have someone on the development team address this issue.

I have been using the new tab group feature a lot over the past few weeks. Today I realized with horror that only the three most recently used tab groups are displayed when I click on the arrow icon “Open all tab groups”. The missing tab groups are very important to me. I hope someone can help me.

Hello everybody, Is there any way to revert unloaded tabs favicon revert back to slightly pale colored version like in 137 instead of non-colored b&w favicons.
