From July 26th, 2012 to June 7th, 2016, 20% user give 5-star rating, 20% user give 3-star rating, 20% user give 2-star rating, 40% user give 1-star rating. for xkcd #37 chrome extension.
I use this semi-frequently for adding custom regex replacements, however: one of the default rules breaks google image search (fancy-apostrophe/quotes, I believe?). Also, *all* of the word-type related rules break (such as adding Oxford commas). as this is the only Oxford comma extension on chrome, that fact makes me quite sad. 3 stars because a) it breaks google image search, b) Oxford comma rule does not work.
This addon breaks google image search
This extension breaks Google Image Search.
added xkcd #1031 too! sooo funny!
I'm not a uber web developer, so I can't pinpoint the problem, but it appears (after systematically enabling/disabling all my extensions) that this addon makes it impossible for me to post status updates and comments on facebook. I even tried disabling the regex's one-by-one; no luck. I love how you're able to add your own regex's, BTW! It is a great addon in concept, and I really wanted it to work, but this problem is an addon-killer. I'll happily take this back if you can fix-it / figure out what I'm doing wrong.
