Diễn đàn hỗ trợ Firefox

I run FF on a Windows desktop. I have 5 pinned tabs and one tab group. Today when I opened FF all of these had disappeared. This has happened before, so I have a screenshot of the 5 tabs and can restore those, but I didn't make one of the tab group (given that the whole point of it was to SAVE the tabs), and unfortunately those were the result of a lot of time spent researching.

Is there something I can to do make sure these tabs all actually get saved from one session to the next? This unreliability of FF wastes a lot of time and starts me thinking about going back to Chrome which at least has the virtue of more stability. What is the point of all these features (I was really happy when you created the tab groups) if I can't rely on them?

Firefox recently started "eating" my tabs: closing them without my permission. There are several tabs I want to keep open at all times, because I refer to them from time to time throughout the day, but Firefox closes them from time to time. I googled the issue and the AI directed me to two settings: browser.tabs.unloadOnLowMemory and browser.tabs.min_inactive_duration_before_unload. It suggested setting the first one to "false" and increasing the duration of the second, or setting it to "false." However, the setting will only accept numeric values.

Since I am not having low memory issues, I want Firefox to leave my tabs alone. Is there any way to actually do this? If not, it would be really nice if Firefox developers reversed this intrusive change.

Thank you, Terry

I have created several groups (currently 4 with a total of 11 tabs combined). When a group is closed, do those tabs become inactive, reducing their impact on Firefox/computer performance, or do they still remain active and impacting overall performance?

Hi Team, I am using Linux Mint 20 Cinnamon. Cinnamon version is 4.6.6. The issue is that I was browsing and by mistake I selected one tab then dragged it for sometime and then released the tab but that created a new window and now the old windows are not visible in ALT + Tab function. The windows are showing in the Firefox task manager and also the box icon in the top right corner in that "open tabs". Now I am not able to even change the window or able to access the opened tabs. Attached the screenshot and as you can see in that there are total 4 windows showing in firefox and one as active but in the bottom on the firefox icon you can see its only 1 window. How can I access the remaining 3 windows? Found one ticket (https://support.mozilla.org/en-US/questions/1477845) in this the recommend solution does not work. When I try to click on the window 1 tabs then I do not get any response. I tried both the solution but none worked.

Thanks for the help in advance. @Mozilla team member is seeing please check and fix this bug if possible.

All of a sudden Firefox started to use alt+number (e.g. alt+3) to switch to that tab (i.e. tab 3 in my example).

Why? How do I disable this? It prevents me from typing any of the special characters that are located on alt + any number key. E.g. I can type the at-sign, not the dollar, or any such character which requires the alt-modifier and a number.

I have 7 windows that show under Window tab, but only 1 is appearing on my screen. How can I get the other ones to appear? (Note: they are not on a different desktop.)

how do I fix column back to its original. I mistakly renlarge it.

on the very top of the page right side there are three images that refer to the page. it usually show one box now it shows two. I want to go back to one.
