urss is a Mozilla / Firefox extension that provides a side-scrolling ticker of your RSS feed(s). Sounds nifty, and it was exactly what I was looking for at the time I first installed it. However, after I tired of it (and discovered Sage) I looked for a way to uninstall. Oh boy.
urss doesn’t have an “uninstall feature,” that being listed as something that’s in development. That’s cool, because Firefox has an extension manager; no problem, right? Wrong. urss installs itself in ~/.mozilla/firefox/[profile name]/chrome/urss where it has no need to be. After thoroughly munging my existing profile trying to be rid of this thing and get Firefox to start properly, I finally started over with a new profile.
All this is well and good, it’s a version 0.x product and all. Except that there are no bugs filed against it. Hm. I went to try and file a bug. Interesting, there’s no bug tracker for this obviously broken extension! Stay away from urss unless you’re interested in testing and fixing it yourself. You have been warned.
