UwU

A must-have for developers. Incredibly useful for multi-user testing.

very convenient to use. Allows me to open several accounts in a browser

This extension is great, a life saver.. I really need to open several tabs with different account set on it, before i was forced to use multiple private tabs/windows and it is frustrating, or using additional browser just for the needs. And then i came across this and try it. And it is very satisfying. no more multiple windows opened and save my time.

A life saver, I think this plugin should be built into the browser; As it's one of the main selling points. It helps with accessing websites that are bloated with trackers like twitter, without sharing it's cache with other sites.

Great and useful addon!

one of my favorite add-ons for Firefox.

LOVE this add-on. So helpful. Especially appreciate that you can have different tabs in the same window to switch back and forth easily while still keeping your info separate!
