One of my favorite apps but please fix it up.

Currently:

It has a problem where it opens double tabs. I have tried every single setting and this still happens at times. it's as if it loads all of the tabs twice, and then sometimes it seems to load them multiple times. have still not figured out how or why it does it. This is currently the worst problem.

Order of the tabs. you can move the tabs around but then when you go to open a tab in a new window you get some random order of your tabs, this seems like a very easy fix.

It would be great to have a way where you could save out the URLs. This would be such a plus as any problems with Firefox, (for example thousands of tabs opening every time you open a certain container) and you might need to refresh or enter safe mode all of your containers are erased. this can be frustratingly sad.

Otherwise this is one of the most powerful functionalities of Firefox
