This was one my favorite add-ons EVER, but recently I can't get the extension to work. All the sessions I created can't be accessed as of a couple of weeks.

I have the same issue as @Tsavkko that sessions arent opening no more after updating Firefox to v105, I can delete them, open tabs in current window, but new window with saved session doesnt open up.

This add on is amazing. I've been using it for years. There's just a small issue ever since I've updated my browser the last couple of times: The sessions are not opening anyome. I have to individually open each tab, but the whole thing at once is not working.

The update causes crashes. (Status May 2024)
When starting FF, it is closed again after opening and loading the tab profile.
After about 8 restarts, FF starts normally again, i.e.: starts > opens window > closes it > and Tab Manager loads the last backup.

Fix please

Das Update Sorgt für abstürze. (Stand Mai 2024)
Beim starten von FF, wird dieses nachdem öffnen und laden, des Tab Profil wieder beendet.
Nach etwa 8x neustarts, startet FF wieder normal, sprich: Startet > öffnet Fenster > schließt es > und Tab Manager lädt das letzte Backup.

Fixen bitte

Nice interface. Enough functionality.

The reason why I instead just use Firefox's own 'restore previous window/tab" function is because this program can't reopen tabs that contain an opened file that has symbols ä,ö or å in it, it seems.
My username on this computer contains the letter ä (I got this computer from someone), and this addon can't open files because of the file path contains ä in the username.
I often have pdf files stored on my computer open on Firefox.

Great app. Highly suggest trying it! Very flexible, Great tool for backing up tabs all the time, and you can save archives of the data I'm really surprised more people are not using it..

Stopped displaying currently open session tabs, and doesn't show Save button unless full screen. It also started opening its own tab and using that generic non-descriptive tab name as the save title for every save. Don't know why this has changed. Pretty well killed it for me.

This extension has been very useful. It has saved me a lot of times when I had accidentally closed a window full for tabs or when the browser crashed. Thank you!

Doesn't show any currently open tabs.
