FORGET IT. Another worth add-on. NO real Instructions how to RESTORE.... It does save something s but NOT YOUR TABS... but does not tell you where, how to restore..... just takes up space without clear instructions on how to save, WHAT YOU ARE ACTUALLY SAVING BUT most important? HOW TO RETRIEVE OR REUSE.
and assumes you only have ONE PAGE OPEN.

I guess for 1 or 2 tabs is ok but why not just bookmark them. What we need is the SESSION MANAGER which Mozilla obsoleted. TOTAL CONTROL by the user, save each open page, hundreds of tabs.....

I didn`t get why i should save ALL tabs instead of just one
