Okay, so here are some concerns and doubts I have had recently when using FF.
I installed both Temporary Containers and Multi Account Containers addons, I configured the first for maximum privacy to isolate every tab and to open every new tab in a new container. Thing is, this deactivated uBlock Origin, so now I see a ton of ads. So I decided to uninstall it until I know how to fix it.
Then, and this happened two times, the first time my browser crashed and it had to be forcefully closed, and when I opened it all my tabs where there, the second time I unplugged my PC by accident and when I reboot it my tabs where there. Isn’t it supposed that my tabs must die when the browser closes? I’m not using private mode but rather normal mode without history since I left it that way so that the previous add-ons could work. Still I don’t know if this is related.
I would also like to know if there is a way in which the browser asks me every time I choose “open a new window” (when I have already a window opened) and where I could choose which profile to open. I know I could create a shortcut with something like -user1 at the end but it’s more comfortable to me to choose from the menu.
Lastly, if I use the dark theme, which comes pre-installed with FF, can websites know that I’m using it or it works the same way as bookmarks?
