Is there a way to transfer my browser profile on Android between Fennec and Firefox?

Fandom has always been a shitty company abusing the spirit of CC licenses. They animating the husks of dead wikis whose communities moved to selfhost just so they can show autoplay video ads.

Support independent wikis by installing extensions https://getindie.wiki/ and https://support.wiki.gg/wiki/Wiki.gg_Redirect. (Also get yourself a mobile browser that supports extensions: Firefox on Android and Orion on iOS).

Unhook for removing crap.

Jump Cutter for the superior video speed experience.

https://privacypass.github.io/ has helped somewhat

There are apps that block opening apps longer than some amount of time.

Can you recommend one for Android?
