Rest in peace @stoically. This is a wonderful piece of work. If any eager coders out there can lend a hand in forking this project, I and many others would greatly appreciate that. My use case is to set the isolation behaviour on middle click to "always" so you can continue browsing within a given container, while opening new tabs in new ones.

Works great.

Due to "helpful" changes in firefox around the end of 2023, you may want to set `browser.link.force_default_user_context_id_for_external_opens` to true in about:config . Doing this ensures that links opened from other applications doesn't end up in some existing temporary containers. Details here: https://bugzilla.mozilla.org/show_bug.cgi?id=1874599 .

This is a must have and one of the main reasons I keep using Firefox.
My only concern is that is has not been updated in a while, but other than that, it works great.

Very nice extension, does exactly what it says, perfect for development.

Wow, what a very well made extension with great customization options!

First of all it does exactly what is says on the tin!

And second, it has a huge amount of options. Like you can even choose a random color each time a temporary container opens *and* you can exclude colors that you already use with some other container! That is awesome.

Easy to use. Does a wonderful job.

This is a useful addon. Sadly, the developer passed away on January 2023, so there is no further updates. You can view the github page to read more about the future of this project (issue#618).

I have been using this Add On for a long time but never had any issues.
Recently, It has started to create an issue.
It says, '' UNEXPECTED ERROR OCCURED''.

I don't know what to do now.

This is so useful for web developers, makes me glad I'm using Firefox. Unlike Chrome's private browsing, every time you click that icon, the new tab has a brand new "cookie jar" so you can be logged into any app with multiple accounts on multiple tabs making debugging a breeze. Also for normal multi-account use.
