This is by far the most useful extension for any browser and is the primary reason I use Firefox over Chrome, Safari, etc. It is particularly useful when trying to deal with multiple Google accounts where you might want to access Google Docs from multiple Google accounts simultaneously. Thank you from the bottom of my heart to the developers and maintainers of this extension!

Amazing add-on. One of the main reasons I'm here using Firefox instead of Chromium-based-browsers. Hope it never gets unmaintained.

Occasionally ends up opening "ghost" tabs when opening links from Google. Also sync doesn't work well across devices and some extensions don't play well with tabs opened in a container, but overall, functionality is good.

Needs more color/icons for the containers, and I can't for the life of me get the syncing ability to work across other instances.

It's a great addon but please add a way to manually add URLs to open in a container, sometimes websites do quick redirections between domains (see Google) and it's impossible to add the redirecting domain to the container! Also wildcard support for manually added domains would be great (eg: *.google.com). Thanks!

"Hide and Show" feature is advertised, and I selected and installed the Add-on exactly for this use case. Now I can't find the feature. Can you please point me to it ?
See 2 "discussion" on this page related to the feature. My Conclusion: Falls short of this advertised use-case. Rating down for the time being until the discussion brings a solution to the restrictions.

I love it! Only thing is: it does not seem to work if a webshop is using Adyen as a payment method. At least with the 'shop' from dpd.nl dpd.de which uses Adyen.

Great privacy protection in a world where you have to comprise and use Google services and SOME from time to time

My experience in this addon is pretty good, but occasionally, The addon kinda reset, so my custom preferences in the addon returns to default state. But my website which i login-ed didn't sign-out, which is a good thing.
