very handy time saver Rated 4 out of 5 stars
I felt fortunate to find TabsUp after an Add-On search as it provides a means for Firefox to automatically open a tab when the product starts up.
Since I have a couple of pages which I always like to have available, this saves a lot of time.
I couldn't find the developer's email address so here are two ideas for additional functionality:
* Offer the option to open specified Web pages using the 'Pin As App' format.
* Offer the option to open specified Web pages in tabs every time a new Firefox window is created (instead of only when Firefox starts up).
Thanks for considering these! I'll be sending a contribution for your efforts.
