Lately I've been browsing through hundreds of ads on a website similar to craigslist.
Due to the similarities of the ads, I have to read through almost the entire ad to decide if it's interesting or not. For the same reason, I've been reading many of the same ads many and more times even though I figured out the first time it wasn't interesting.
I want to write a note saying: "Not interesting" that will appear the next time I enter that ad. Is this possible to achieve in a simple way or would I have to create my very own add-on? (I can use whatever browser that makes this possible (except Safari)).
