Hey, I am started to get really annoyed by those stupid sites that have random words in paragraphs linked to advertisements and wondered if there are any Firefox addons or something that would detect and block them?
You mean the SEO tags in the left/right sidebar on some blogs (SEO tags: keywords that link to other pages of the same site, it's for SEO purpose) Or people who spam your site? they inject their tags in posts.
I guess you mean the directory sites and listed sites. Many sites are automatically create contents for their sites, since those are not contents write by human, they are not readable/understandable. They are random keywords and they not in order.
No what I mean is this: http://www.techsupportforum.com/graveyard/archives/109596-advertising.html If you look through those posts you will see random words hyperlinked and when you hover over them you get a popup window. I find it really annoying when you don't mean to hover there and you gotta click it away to read the text on the page behind it.
