Rated 5 out of 5 stars

Great extension. Always being actively developed :-)

Ps is there a way so that if I already have a tab/tabs open and I click on a folder, 'open all in tabs' that it will not close my existing tabs - currently it closes my existing ones before opening 'open all in tabs' Thanks.

Edited for reply.
Many thanks for the speedy reply and resolution.
Thank you again for a great extension.

This review is for a previous version of the add-on (0.4.0.2.1-signed).
