I thought this would be a great solution for all my tabs. I clicked the icon and watched all my tabs close. Then I got this error: Error code: SSL_ERROR_RX_RECORD_TOO_LONG

So it seems there are limitations that are not noted in the description. I have emailed the team for tech help, but am assuming my tabs are gone (even with recovery in place with Firefox, I could not seem to get that particular window of tabs restored). Incredibly disappointed in this add-on, and now instead of saving time, I am wasting time trying to figure out recovery. Lesson learned. :(
