I have been using firefox for 3 to 4 years now and it's the best brower i have ever used but from a few months it have gotten too slow i am a student and need to create projects and research alot so i have to open around 20 tabs at a single time but before even after opening 30 tabs it would be fast as ever. I don't have any security extension or whatever i just have AdGuard AdBlocker extention, volume booster and grammerly and screenshot taker and hoxx vpn (it was before as well) but the firfox has become so slow now. (I have custom and max protection on) and additional windows protection too. and sometimes it just stop responding and also hangs up and closes own it own.
