It's a little confusing on first install. It looks like it's not working, because when you open a new tab it doesn't show that it's in the container. But as soon as you start using the tab it'll be in the tab you came from.

It works, but if you try clicking a link on a facebook related page with facebook containers on, it bugs.

First I was happy, since it seemed to does exactly what was advertised.
Opening a completely new Tab first looks, like its the default container, but switches correctly after entering a search.

Then problems occurred too often to be ignored.
Sometimes it clashes with tabs, that want to be in a concrete container and keeps reopening them to infinity.
Sometimes opening a new tab in a different container results in the extension switching that container back to the last one, even if I wanted that new container.

All in all I am happier with the Simple Tab Groups extension, where I also get my new Tabs correctly contained, while being in the correct group. (Since that extension comes with a lot more functionality, it couldn't be everyone's cup of tea)

Too many bugs. Makes new page and new tabs not to open in some use cases.

The idea is excellent but implementation is just too buggy.

Seems to be working exact as advertised

Interesting idea but it's buggy right now. It opens double tabs when used with "Auto Tab Discard" add-on.

I really liked this until I realized that this was causing my firefox new windows to close the second they open. I believe the problem comes from the extension being unable to decide which container to open a new tab in a new window in, so that needs to be changed. I would love to rate it higher, but this is a really bad bug

Broken. After installation, new tabs don't open anymore - only new windows!

Windows and tabs instantly close when opened from a container tab

Does not work at all.

It doesn't work :(

Did not seem to work at all, even after a full Firefox restart.

Does exactly what I wanted when opening new tabs, though it does it after you put in an address in the default container.

Unfortunately, it doesn't allow me to easily open a new window; when you attempt to open a new window from a container tab (Alt/Command-N or File->New Window), the new window immediately closes. You can still open a new window via opening a new tab and dragging it off of the original window, but this is very inconvenient in an multi-workspace environment like KDE, where I often simply want to open a new Firefox window in the current workspace. Moving to the original workspace, dragging a tab out to make a new window, then bringing the window to the workspace I want it is really annoying to do when I simply just want a new Firefox window now.

For my use, this issue makes the add-on basically unusable. Hopefully, this issue can be fixed, or this feature can be part of the base Containers system.

A good interim workaround for bulk tab imports until they get open in set container/open in original properly sorted.

It reopens the tab when the tab is clicked, in the container that was active before the tab was imported.

Drawbacks: Not working properly with tree tabs.
The tab order is changed, tabs are re-ordered into the order they are activated, and tree structure is lost. (This happens using tree tabs addon, may be caused by it??? - Might this be because the old tab is closed before the new tab is opened?)

Brilliant for bookmarks, onetab etc until open in origina container gets sorted.

Works like a charm - needs to be part of the default container implementation.

Only gripe is that the address bar is not in focus on CTRL+T requiring one to reach out for the touchpad/mouse(or double tab again) on opening a new tab to get the focus back on the address bar.

Almost did the work what David Lynch explained however slight adjustment needs to be done... From A type container it is going well to new link in A type container however when I tried to open a link from default type container or No Container it didn't work...

A must-have when you use containers. When using Ctrl+T, it might looks like the new tab is in the default container, but at the moment you enter an URL, it opens it in the correct container. I've been looking for this a long time - I tried a lot of unsatisfying "hacks" - but this extension perfectly does the job.

Much needed functionality for those trying to make the switch from Chrome!

Protip: use separate windows for different containers.

With this extension containers actually work how they always should have. Containers + this extension is now way more powerful than Chrome's profile switcher.

This extension solves an annoying problem with containers - when you open a URL into a new tab (ALT+Enter on Windows) from the address bar in a container, Firefox does not normally persist the container. This extension does! Great work.

Essential if you use containers.
