Hi, Today when I powered on my pc and opened up firefox all tabs were lost. I have the option to retain tabs when opened up enabled. I could not find them anywhere, so I had to search opened tabs from the other synced devices and click on each of them, and create again all the tab groups. This is a big problem if randomly all the tabs can get lost, am I doing something wrong? Another thing : I thought that when I create groups of tabs, and save them I coul retrieve them across all my synced devices, but the other devices can not see those groups, is this a normal behaviour? Thank you
