Rated 5 out of 5 stars

using it for long.
However I found that the similar extensions will have these problem:
1. having chaos in tab group after entering private browsing mode
2. can't open a new tab after entering URL in url bar
3. won't remind to close the browser even choose the option.
hope those can be fixed! thanks!

This review is for a previous version of the add-on (1.2).
