I've been using SM for years on Firefox. I have used it with up to 125 tabs in 7 different groups without a hitch. The built in feature to keep multiple sessions is great, allowing me to transport sessions to multiple computers / share across multiple profiles. It really is a must have addon for anyone using Firefox.

Now just patiently waiting for an update to work with Fx Nightly 57.0a1
