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.
Can't help with your question, sorry.
When that happens to me in firefox, changing to another tab and back usually fixes it.
You can turn off miui optimizations to stop it from immediately killing every app you leave in the background.
(and not to digress but you shouldn't use a stock miui rom if you care about privacy)
If only there was a way to disable MIUI optimization or change ROM witgout losing all your app data in 2024…
