Regarding tab isolation etc, do you know if in about:config setting the storage partitioning (by site, proxy, eyc) and/or disabling automatic storage access makes a difference? There are options for strict site isolation in there, too, but I don’t know if toggling one thing will break another.
Also, don’t containers on FF on Linux do that?
browser.discovery.containers.enabled
privacy.usercontext.enabled
BTW, thanks for these posts.
Sadly moz Dev is … Difficult to find info about things other than the function and how to call it. The source is all there, and some things are buried so deep in some topic or obscure inaccessible part of their site. But practical functionality and actual results of use are difficult to determine on my lonesome.
I use the tests on https://librewolf.net/docs/testing/ to do some things, but there are just so many unknowns.
Thanks again.
