Does what it needs to and managed to solve a stupid shortcoming of not being able to manage multiple accounts on Twitter for me. Yet another reason to use Firefox and some of Mozilla's wonderful extensions!

thanks ! great

Great add-on if you have a lot of accounts

This extension must have by default!
Great!

Most valuable add-on for my workflow to have it all in one browser and even window. Perfect for dealing with different environments like DEV, STAGING and PROD and multiple Accounts.

Great Addon for privacy

This feature has been very useful to me. Especially with regards to separating work and personal accounts and functions.

This is a very useful addon. Ability to login with multiple accounts at the same time is very useful

At work, I have to deal with multiple accounts for the same platforms, like Outlook 365 and Atlassian. This add-on helps me a lot by separating the sites by category and allowing me to open only one browser window to access everything.

Highly recommended for anyone with a lot of tabs. Create however many groups you need, hide groups you're not actively using, and show groups when needed. Save memory by hiding tabs you don't need until later :)

Excellent add-on for separating accounts.

great idea

Super convenient way to make sure cookies don't track you all over. Gives more control over how websites can track you.

Works great.
