Didn't want to make title too long, sorry. By load back I mean read from clipboard or from a file or have an input box to paste from clipboard a lost of URLs and open each in a tab.
On my phone (it's a MIUI device) firefox sometimes acts weird, I can see URL in a tab but page looks empty. I can copy the URL manually, close the tab, open a new one, but this can be annoying if I have many tabs and this also changes the tab order.
Also, no, I can't just close firefox and open it again, as I mostly use firefox in private mode.
I just want to copy all open URLs, restart firefox, and open all my tabs in private mode again in the same order by pasting URLs back.
Also, android aften kills my firefox when it's in the backgroind without any warning.
Last time I searched, I couldn't find any such addons, but it's possible that I used wrong keywords.
You can multi-select regular tabs to add them to a collection, but not private ones. And even if you did add each private tabs to a collection one at a time, the "open tabs" option only opens them as regular tabs, not private ones.
Instead of private tabs, have you considered
I do have multiple browsers, for multiple purposes.
Maybe one more won't hurt.
Too bad Mozilla treats private tabs differently from regular tabs though.
