This is a continuing problem that showed up on version 127, maybe 128, and continued through 129, and now to 130.0.

Attempts using Firefox to play movies at HD (highest 6GB data resolution) fail. Using, for example, the Edge browser works fine. This problem showed up as noted in the first sentence of this post. Manually changing an obscure "about:config" variable from 1 to 0 did not fix the problem.

I just updated to 130.0, immediately tried to play a movie at highest resolution, it failed. Changed the obscure variable from the value it had, 0, to 1 and it failed still. Changed it back to 0 and it failed.

My firefox crash, I uninstall and re-install. i logged to my Mozilla account and the sync does not work. I don't have my password or my bookmark.

I still have everything on my phone How can I force the sync or retrieve data in an xml/csv file ?

When I check "Check spelling as you type" and choose size of fonts and then close my browser it doesn't remember the settings chosen, IE, when I open it again, go to settings the "check spelling as you type" isn't checked and the size of the fonts shows earlier setting
