But however, I just noticed these scripts works only on Desktop devices (i.e both Firefox and Chrome). So I would have loved to ask, can such also be done on Mobile device, that is either Android or IOS?
You have noticed wrongly my friend. These scripts is also works on the mobile device but the browser should be extension supported. For that I am using the Kiwi Browser more than two years. You just need to install those browser like for Android Kiwi Browser and for IOS Yandex Browser.
Is there a way to make it work with Safari or Chrome mobile?
Iphones are pretty picky about browser extensions.
I succeeded in using the @babo extension in Safari using user script, but I somehow failed with this one.
