Greasy Fork

it dont work for me [my browser is kiwi browser]

It's not made for mobile. I just tried it on Firefox for Android (my first time testing it on mobile), and it's unusable by default. The only way it sorta works (but not without some visual bugs) is if you use the Desktop Site, and that's not a great experience.

i am using desktop mode and i use tablet and i use keyboard and mouse

Then I guess it's a Kiwi Browser issue. For unknown reasons, Gplex (and some other userscripts) seem to not work in some Chromium based browsers (namely Chrome Beta and the Chromium browser itself), even on desktop. So your best bet is to try using Firefox instead (Gplex probably works best on it anyway).
