Related if anyone is switching over. I like to run Firefox Developer Edition[0] as my "work" browser, with work related bookmarks, etc. and then regular Firefox for nonwork. This makes it really easy to keep the two separate. I know there's a lot of ways to segment within the same browser but this works well for me.
You can achieve the same (or similar) thing with Firefox profiles. Just launch with "-p" and it'll give you a profile picker. You can have a work profile with separate extensions, bookmarks, settings, etc.
Same branch as beta, but with different build flags. Add-ons don't need to be signed to be installed on DevEdition, there's a DevTools button in the toolbar by default, etc.
Chromium has a concept of "user data directories" which in theory keep all data isolated to a single folder. You can use a launch parameter to specify what the user data directory you want to use is (so a shortcut). I'm pretty sure Firefox must have an equivalent.
Yes, I used to always use a work profile and a home profile in Firefox. Over time I simply made more containers and stopped using profiles altogether. But the option is still there.
Thanks. I didn't use uBlock but I will be switching due to Chrome removing support for non-subsituting keywords (search engines with no %s), which I used heavily as basically aliases for web addresses.
I just use multicontainers extension for that sort of thing. It keeps them siloed off from each other. Great for having multiple accounts on sites like bsky and reddit as well.
