I recently found Locationbar² Firefox extension somehow, and thought it is nice to have it emphasis the domain name of the URL you are in.
Only today, when I wanted to tell some friends about “Family Guy” for which I recently fell after reading a post in some Hebrew blog I don’t usually read, and wanted to link to the Hebrew Wikipedia entry about Family Guy, I noticed that Locationbar² makes the Hebrew Wikipedia URL readable, and not containing long list of escaped character. I verified that indeed, its second feature, after “emphasizing the domain name” is “[d]ecodes URLs for better readability” with a sample from Ukraine Wikipedia.
Very cool.
Update: I just found out this can also be handy when you have Google searches with special characters, where it is hard to see the search phrase from the URL without Locationbar².
