Since I've seen a lot of chatter about people switching to #Firefox as Google ramps up the enshitification of #Chrome, let me tell you about a killer feature for people who (a) need multiple accounts on the same websites (eg. devs) or specifically (b) have to use multiple Google accounts.

Firefox has an official addon called Multi Account Containers that lets you trivially set up color coded tabs that have separate sets of cookies. Log into your dev account in one, and your test account in another. Log into your personal #gmail in one and have another tab next to it with your work Gmail. I'm actually not signed in to any Google accounts in most my tabs, I just have containers for the specific tasks I do on Google products.

It'll take you 30 seconds to set up.

Firefox Multi-Account Containers – Get this Extension for 🦊 Firefox (en-US)

Download Firefox Multi-Account Containers for Firefox. Firefox Multi-Account Containers lets you keep parts of your online life separated into color-coded tabs. Cookies are separated by container, allowing you to use the web with multiple accounts and integrate Mozilla VPN for an extra layer of privacy.

Thank you. Will give this a try.

Alas, looks like it isn't supported in Android Mobile

@pseudonym Alas that does seem to be the case. I saw something a while ago about Firefox bringing desktop extensions to the mobile browser, so perhaps that will change in the near future.
Firefox’s Android app is getting proper support for extensions once again

Firefox’s Android app will soon support an “open ecosystem of extensions” allowing users to customize the browser with a wide range of third-party addons.

I use Fennec (Firefox for Android). With a small hack, it is possible to use nearly all plugins, instead of just few preselected ones. The hack is descibed at https://www.reddit.com/r/fossdroid/comments/p7mgec/guide_using_most_all_firefox_addons_on_fennec_on
Guide: Using most (all?) Firefox add-ons on Fennec on your phone

Hey, I found out about this recently and apparently a lot of people don't know about this either, so here's a quick guide that's not much more...

@goodmirek @ricci @pseudonym Ah, I didn't think Fennec was still being developed
@jbowen @ricci @pseudonym I install Fennec via F-droid and there is a new version every few weeks.

Good to know. Thanks for the info
