disable fullscr-toggler
So basically i had done what i need to do base on the advice in
https://support.mozilla.org/en-US/questions/1412553
i had added chrome file in the profile folder and done all as the picture shown below
after that i do about:config make legacy -> false to true, i do a restart my windows and check on profile folder it change to .... Firefox\Profiles\*censored*.default-release
- i censored it afraid that it was a important information (im not a techno guy)
but it doesnt change a thing. i was playing diep.io and agar.io whenever i hover it to the top it still poppin up
any suggestion?
