Export selected tabs only

[Lamiane]

Currently, Firefox allows for selecting multiple tabs (Ctrl + click on the tabs). It would be nice to have an option to export urls of selected tabs only.

Usecase: This addon already allows for filtering tabs, which is a great option if all the tabs of interest share some part of their url, for example they come from the same domain. However, it might be the case that a user wants to export urls of websites that share a topic but come from different domains - for example web pages about giraffes.
