I WANT TO MANUALLY ADD/EDIT URLs DIRECTLY IN THE ADDON "MANAGE SITE LIST" FOR M-RLIN'S SAKE!
HOW HARD CAN THIS FEATURE BE?!
I GET SO MANY REDIRECTS PER SECOND IT JUST BURNS MY CPU AND THEN GET BANNED FOR "TO MANY REQUESTS".

Key reason I use Firefox is for Multi-Account Containers and managing multiple 365 tenants.

It was working really well, I have multiple MS and AWS logins and I used this to enable multiple login sessions in different tabs. I don't know if MS have changed how the sessions are identified or an update broke it but it no longer works, I'm back to opening everything in private browsing sessions... Boo :(

Excellent extension. I haven't been able to duplicate this functionality in a Chrome based browser. So, kudos to the Firefox crew for building this add-on. It's one of the reasons I continue to use Firefox. The broad range of add-on extensions remains an attractive and desirable feature of Firefox.

Hopefully it can be added to choose whether to prompt for a selection page! ! ! !



Do you want to open this website as the identity you specified?

Works well in cooperation with Cloudflare WARP (proxy mode).
The extension allows for specific selected sites to bypass censorship.
Does not affect all other sites and other network connections. Which is very convenient.
use socks://localhost:port
exactly localhost, not 127.0.0.1

This is game changer and not the reason I stay with Firefox. However, when question of Brave comes up, with all that they do, although they are building off chromium code so maybe it is a function that cannot be implemented ( I think it can be but not sure if maybe some limitations that would make it not as effective as what Mozilla can do with having their own engine for their browser ). I am with Firefox regardless. 65% Firefox, 25% Brave, and 10% Chrome, last one to sandbox off google and microsoft from touching other browsers but all it gets are those two companies plus yahoo.

A great addon that makes Firefox an even better browser. Being able to have separate environments for separate "personalities" integrated into the browser like this is fantastic. Just being able to log in with two entirely separate accounts to the same site at the same time with the same browser is huge for me.

very helpful

one of the best feature of Firefox, maybe best implementation of tab groups
