Back in 2022 I said that my Firefox addons hadn't changed in a while , and while that's still mostly true there's been some minor changes that I want to write down. Addons are central to my Firefox experience, but I don't change them very often partly because of that and partly because I'm much more conservative with Firefox than I am with things like Emacs packages . I'm generally happy with my Firefox environment and most of what I do with it is stop irritating changes and fix things that get turned off .

Of my old addons in my main Firefox setup, I still use Foxy Gestures , uBlock Origin , uMatrix (which is still not quite dead ), Cookie AutoDelete , Stylus , Textern , Certainly Something , HTTP/2 Indicator , ClearURLs (although that may be ineffective these days), and Open in Browser , although I'm not sure that's doing anything for me. I no longer use HTTPS Everywhere. Because I switched from Firefox's default "storage partitioning" for cookies to the stricter "first party isolation" , I had to switch from Cookie Quick Manager , which I don't think works with either of them, to Cookie Manager , which does work with first party isolation as far as I can tell. In my main Firefox, this is the only addon change, although in a sense there's another change in that I'm now pervasively using Stylus .

I have a second significant Firefox environment and in this environment I recently set up a container-based setup . This setup uses Multi-Account Containers for the basic multi-container support and FoxyTab to assign wildcarded domains to specific containers. This second Firefox now also has Cookie AutoDelete (it didn't used to), and also I've installed a few other addons over time: Copy Alt Text , Don't Fuck With Paste , Right-Click Borescope , and User-Agent Switcher and Manager . I have all of these in this Firefox because this Firefox allows JavaScript generally, which allows websites to do a lot more things that I want to override and examine. My normal Firefox blocks JavaScript, so websites can't readily do things like blocking paste. I don't use these addons very much, so they're mostly around in case I need them.

Although it's not a change in addons, a significant change in my Firefox usage is that my second Firefox environment has moved from being disposable (with everything discarded when Firefox shuts down) to being persistent, because I admitted to myself that that's what I was doing with it . This is part of what pushed me to add Cookie AutoDelete to this Firefox profile; even before I made it persistent, I admitted that I wasn't shutting it down very often and so cookies were increasingly lingering in it.
