My Firefox are lagging when i try to open a new windows on both normal and private browsing mode. It have a serious input lag when i try to type in the address bar and the search bar, about 1 to 2 second for the word show up. The problem is fixed when i am on the safe mode. So i went and refresh the Firefox and remove all the extension, the problem still persist. I also tried some other method suggested by other after my research, create a new account, turned off the hardware acceleration, set accessibility.force_disabled. None of them work, any clue on how can i fix this problem? The lag only happen on Firefox, i tried to typed on other software its fine, but i switch back to Firefox the input lag happen. Thanks and have a nice day!

Download another copy of Firefox to a folder and run it from there to see if you have the same issue. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release
