Nice Rated 5 out of 5 stars

Really nice, deserves to be a featured add-on, MOST IMPORTANTLY this add-on WORKS according to live http headers, btw have you ever considered that this amazing add-on can stop google tracking* your search results!?!
While this add-on does not always work(sometimes on the same page xD) but it is doing much better than I would have expected so I present the author Diego with my thanks

edit: why is there a # on the links?
edit2: so odd, I noticed with live http headers that this add-on works with google ONLY when fireglove is enabled, so odd because another add-on that performed a similar function failed with fireglove enabled.

This review is for a previous version of the add-on (2.1.1-signed.1-signed). 

Yeah, tracking protection was the main reason as to why this add-on was created :-)

The hashtag is added because AdSense adds a counter to links, stating the number of times you moved the mouse over links. Thus, it ensures the link is clickable in case such counter is added after it has been cleared by this add-on, otherwise it'd cause a 404 error.

Regarding that weird conflict on Google... try version 2.2.1 and let me know if something changed. Keep in mind Google works differently depending if you are logged or no.
