How to Fix

So it appears that there are two different fixes. One of them completely removes FireShot, and the second leaves FireShot installed. Both appear to work.

Fix #1

  1. Uninstall FireShot 0.31
  2. Restart Firefox
  3. Enter about:config in the address bar
  4. Search for any variables that contain fireshot (I think this is the one that is causing the problem: general.useragent.extra.fireshot)
  5. Right click on each one, and select reset
  6. If you want, re-install FireShot version 0.25

Fix #2

  1. Open the FireShot preferences
  2. Uncheck Add information about FireShot into user-agent string
  3. Restart Firefox

So a couple of my Firefox add-ons had updates this morning. I installed them all without even thinking about it, and my co-worker Adrian asked why I added the green background to my sIFR headings. I had no idea what he was talking about. He said he also had a Firefox add-on that was updated, FireShot.

Homepage with weird green backgrounds

I checked in Firefox on the Mac, IE, and another co-worker's Firefox on PC, and none of them had the green backgrounds. I disabled JavaScript, and the green backgrounds went away. So something is going on with my sIFR headings. Weird.

Anyone else seeing the green backgrounds? Anyone know why?
