This is not a replacement for Tab Groups as Firefox suggests, this is archaic and can't do a tenth of it feature-wise.

Sometimes the scripts of certain pages that are contained in one container are used in the pages of another container making some kind of Cross-Sripting and blocking pages such as Wikia.com and many others. Basically it's because most of sites are interrelated.

As well that when a link is opened from inside a contained page that link is contained either and not independently from that domain containing.

And now it just logs out my accounts that were not in a container and later I tried to log in to them in the default container instead, and actually can´t mark to open them always in the default container.

Funktioniert nicht

While the add-on mostly works okay it causes some strange problems. On sites such as pinterest, if I click on a link to open in the same tab, it works fine. If I middle or right-click to open the link in a new tab, the first image or header displays, but the rest of the page is blank with a spinning wheel icon at the bottom, as if it's loading more (which it's not, there is no loading indicator on the tab itself). It does this for every link on every page of pinterest.

With this extension disabled, I get the normal expected behavior: the page is complete on both same and new tabs. I'm only using pinterest as an example, because I know the general layout of the images there. I know when I'm not seeing most of the page. Since I don't know this for most other sites, I don't know what other information on not seeing on those sites when using new tabs with this extension.

Until I know I can open in a new tab without losing information, I won't be using this add-on.

It worked great until all my add-ons got disabled. Because that got rid of all my profiles for this add-on.
