It seems to have stopped functioning properly in Firefox version 141.0
I still see my list of containers to push tabs into but they don't open in the associated container anymore when visiting a page.
Edit: The list of containers I had in the editor was gone hence it stopped matching new tabs to the rules I had in place. Very obnoxious.

Good, but unmaintained...

Can not sync container rules between devices.

Amazingly useful!
Two issues:
- has not been updated in over half a year
- if a rule matches in both Containerise and Multi-Account-Containers, the tab duplicates :/

(Маленькое) всплывающее окно дополнения не растягивается, и маска доменного имени совсем неочевидна. Рекомендуемый в описании формат !*.amazon.co.uk не подходит, потому что перекидывает не по домену местонахождения, а по наличию буквосочетания в адресе, включая часть поискового запроса. Например, https://www.google.com/search?client=firefox-b-d&q=amazon.co.uk или https://mail.google.com/mail/u/0/#search/amazon.co.uk перекинет в контейнер, назначенный для Amazon, а не для Google. Все domain.net приходится дублировать www.domain.net. Несовместим с Web Archives.

Latest Firefox 72.0.1 for Linux Mint broke colors for different containers.

The add-on seems very promising, but doesn't seem to work with Conex, I use intensively.
Can the 2 be made compatible ? or even merged, if I dare to suggest ?
They should be really complementary.
Have nice day!

This is a great start - but it needs works:
- Sync my settings between Firefox installs.
- Set a default container

Otherwise it works really well.

I created an "untrusted" container and it does not work.
Works fine on the default containers even after I renamed them but not with selfcreated.

Please enhance the extension with an option to automatically add a rule if I open a website in a container. Copy pasting URLs into the extension consumes time.
