The final feature I am waiting for is a way to control browser extensions per container. No extension should be running when I login to my bank or insurance portal.
For example, I have a profile for watching videos via Amazon and Netflix, which uses dark mode and some high-resolution extensions, but not tree-style-tabs which I use with my normal browser profile.
I have one for work and one for non-work and it's great!
/usr/bin/firefox -P my-profile --no-remoteI actually have some scripts for managing not just profiles but extensions. Hopefully I can get it cleaned up in time to put on Github.
As my extensions include ublock0, umatrix and cookie autodelete normal tab close behaviour usually eradicates everything.
