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.
Yeah, I knew about the unavailability of Tabstash, which is unfortunate. It would be the best option. However, I learned something about Onetab today - I thought it was strange that you couldn't get it to work, when I used it just the other day on Android. But if you look at the FAQs in the Details section (see attached screenshot), it only can save the 'active tabs' as dictated by Firefox Mobile, so in that sense it's not ideal.
Yeah, seen that too.
