With Safari's version of AdBlock (and I suppose this is the same for all the other browsers), I can use its advanced options to block whatever I want in specific domains (or even in all domains), which allows me to remove AdBlock blockers, ads that AdBlock can't detect, and things that I don't like, like chats of specific websites and links that direct me to websites that are already dead, like Megaupload.
However, sometimes I just want to change a specific A tag text, or increase the size of a DIV tag, but that's not the purpose of AdBlock, and so it doesn't have that has a feature.
My question is: How can I modify components in websites in the same way that AdBlock lets me block them?
While writing the question, another one appeared in Similar Questions with that answer suggesting Quickscript:

However I tried it, and it doesn't seems to work with Safari 10.1, which is my version.
