I generally have a "home" Firefox window with my most used tabs pinned. Sometimes I close it before another window, so I was frustrated to "lose" it and having to redo my pins. But recently I discovered this feature. Joy!
Good tip, though I have just hidden the close button with userChrome.css. It does not protect against alt+f4, though..
I also like that its PDF viewer opens exactly at where I left it at.
@OP When you have continue session on, closing Firefox using burger menu->Quit restores all windows. I assume this will also keep the pins even without continue session.
Saved my butt a few times already.
It works until Firefox applies updates and the next time you open it it automatically loads a "what's new in Firefox" tab erasing your previous session. Then you're SOL unless there's some way around that.
After updates, mine always opens all of my tabs. Maybe check your settings.
I've not started a fresh session of Firefox in years tbh. Not sure why it is different for you.
For reference, holds true on my phone, desktop, sim desktop, programming laptop, hobby laptop, network testing laptop, media laptop, backup management laptop, steam deck, second steam deck, virtual red hat machine, virtual windows machine, and hackintosh. So, a wide variety of environments. Never experienced this issue.
You're being downvoted or something but it's same for me.
I love Firefox but every time I update it there's this page with "Yay now you're safe because you updated" that randomly can open as a new tab in my existing session or as a new window with a single tab and erase my previous session. And I hate it. Like, this page doesn't give me any useful information, I never asked for it, I can't turn it off, and that's not all of the problem, even more, this stupid page loses my information and undoes my work of opening and arranging my tabs the way I like.
In my FF I have set the "reopen all tabs that were there when I closed" option, so it never has been a problem
