Firefox Support Forum

I use to be able to work on one app/window and hover over multiple tabs to obtain brief details on the browser (tabs) as it sits behind the app/window I'm currently working on. Since about a week ago, this feature has gone away. Now I have to be on the browser to be able to hover over the tabs to obtain the info I need on the tabs. I do this to compare the order # that displays on the tabs for what I use it for. How do I get this feature back. I want to be able to hover over tabs to view the small details even when not currently on the browser itself. Please help.

On my Mac (High Sierra), I can't make Tab font larger even after using jscher's great fix using about:config and devp. It worked beautifully on Linux Mint (Firefox 103) but not on Mac with Firefox 115. Will be 80 in July. Want to fix this soon . . . ha!

Ok, I've resolved this in the past, several version of Firefox ago, under windows. Firefox crashes silently, open it again and no tabs are restored. Open firefox again and look in recently closed windows and the one with my tabs is not there, only little utility windows that are popped up when I log in at the coffee shop, so my recently closed windows are overwritten with windows with no tabs.

So I go to my profile sessionstore-backups folder and copy it to the desktop. I have 6 files, previous.jsonlz4, recovery.baklz4, and recovery.jsonlz4 at around 8 megs in size. I copied each to the folder one level up and renamed them sessionstore.jsonlz4, and each time restarted firefox. All that opens is a blank tabbed firefox window.

There was never an existing sessionstore.jsonlz4 file anywhere I could find, even with firefox closed, this file never appears anywhere I could find it. Searching files with Windows was also unsuccessful.

I feel like I have captured the files with my tabs, based on the date modified, several were from before the crash. Why can't I find a working tutorial on how to restore my tabs? Nothing I've found on the support site works though I follow the directions exactly.

Thanks
