Attached the info. As an aside, I have a second system, installed at the same time and in the same way (Ubuntu 21.04, then upgraded to 21.10). The second system (my desktop at home) shows neither of these issues (this one and bug #1948355). The bookmarks and settings are all synced from the same Firefox account, and they're synced with each other.
The hardware differences are that this machine is an intel laptop with integrated graphics, the other system is an AMD desktop with an AMD GPU. For software, I may not have all the same extensions enabled. I will get this data from home and compare tonight or tomorrow. ** Attachment added: "about-support.txt" https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1948356/+attachment/5536089/+files/about-support.txt -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1948356 Title: Firefox 93.0 tabs are not remembered across sessions Status in firefox package in Ubuntu: Incomplete Bug description: If I close Firefox with a bunch of tabs, then open again, the tabs are gone. I get a list of empty tabs without any actual link to them. Only the last visited site is actually filled with the URL. Up until now Firefox always remembers and restores the list of tabs. I am using Tree Style Tab, but I believe it uses the regular tab list for itself.
