I find the authorization for “Access your data for various websites” extremely powerful. Firefox explains the following on its website:

“Access your data for all websites

The extension could read the content of any website you visit as well as the data you enter there, such as usernames and passwords.

Extensions that request this authorization could:

Read product and pricing information on a website to find the best price for items you want to buy.
Provide a password manager that reads and writes details of your username and password.
Provide an adblocker that examines the content of every web page you visit to find and remove ads. ”

I saw comments/reviews mentioning "right-clicking the tab doesn't offer the option to rename a window"

I was also confused initially, but I realized that you need to right-click "Window 1" bar in the add-on's drop-down, not the window itself.

My main desire would be allowing me to minimize the windows' lists so I can navigate them in the add-on quicker instead of having to scroll past all the tabs to get to the window I want to rename/manage. There already seems to be an issue on the github repo requesting the ability to fold the lists, but other than that it's a simple little tool I already appreciate.

I downloaded this so I could move tabs between windows and it works very well but in recent months sometimes it will crash firefox when I move a tab. If it wasn't for that it'd be 5 stars.

I downloaded this so I could rename tabs- description says "Right click on a window to rename it!" - but it does not.
