Excellent add-on, essential for my work!

Great extension for an extra layer of privacy or using multiple accounts of a web service within a single browser.

I like this

This extension is all I needed.
Major issue I faced is it fails to open the specific bookmarks in the designated containers.
Other is opening tab by keyboard shortcut is limited to only ten containers. If there is a functionality to increase that then this addon would be great.

good for getting around jerk moderators who block you cuz you don't give the same opinions they have sites like:city-data and other jerk run sites run by morons. Have to keep checking allow permissions to delete container data. Easy to make a mistake and send in non-container if you're not careful. Mozilla wants you to add their VPN to the containers but their VPN gets such poor reviews no need. slow to load up.

Cannot use the containers without giving a rating so you get one star. Nagging is a shitty tactic.
Edit: A review is not enough. Are you actually forcing people to post on facebook and twitter to gain access to this extension?

the review nag is annoying, but the feature is great and works well

works well, no problems so far, good isolation

Super useful extension. Enough for me to switch to Firefox.

I shouldn't have to rate, share, or otherwise promote an official Firefox extension just to be able to use it. Make sure this "feature" gets removed soon so I don't develop a competitor. 📎
