I use Firefox for the same reason, especially that, thanks to tab containers, I can be logged in in one tab and out in another.

Linking your browser login to online services is incredibly invasive.

Regarding tab containers: last I tried them there was no way to clear cookies in a container. Is this still the case?

Still the case.

The features is no used enought, people don't know about it, and because of that, there is no pressure to improve it.

E.G: the "forget this site" button will remove all cookies, local storage, cache, etc. for one site. Very handy, because I don't want to bust my entire cache every time. But it will remove them for all containers, which sometimes is not what you need.

Thanks. Ironically, this also means that chrome has more visible support for tab-containering, with its clear support for simultaneous windows with different profiles. Can I do the same in Firefox?

About:profiles is what you are looking for.

This is a messy workaround, but I just delete the container and create a new one with the same name.

Why not just use Firefox?

I've recently switched from Chrome to FF on Android. It's better in many ways, but it's noticeably and frustratingly slower on nearly all websites. For example, trying to minimize a comment on HN is now very frustrating as there's a >1 second delay which frequently results in me tap the target multiple times causing all kinds of weirdness.

Are you running Firefox Preview/Nightly? I've found them to be even faster than Chrome on my device.

That might be an android thing.

I keep seeing people say that but as a Linux user, Chromium has hardware acceleration and works better with Wayland.

Did you try Firefox-Wayland lately? I use both chromium-freeworld and firefox-wayland on Wayland, and no problems so far. Also, hardware acceleration is meant to land in Firefox 76[0]

Yes and yes, unfortunately can't wait around for Mozilla. This has been a problem for years now. Even with Mozilla's new official VPN service, and similar to their password manager, they did not start with support for Linux and it is always on the backburner. Until they want to prioritize open source first I am not interested in their solutions. I use chromium on Arch and it has hardware acceleration and everything else I can adjust through my policy file.

Why don't you just use Firefox then?
