Long-term Memory

I tried to upgrade my silverlight plugin from version 3 (3.0.50106.0) to version 4 (4.0.50917.0). I downloaded the DMG, followed the wizard all the way through, restarted Firefox as requested and saw that I was still at version 3… Strangely, Safari did load and use version 4, so the install was successful. So I searched my entire system fore some remains of Silverlight 3, without success.

The only place I could find the old version mentioned, was in the pluginreg.dat file in my firefox profile. I just erased this file, and it all magically worked!

Fifefox has a very convenient auto-complete function when filling in forms and logins. Very convenient, until you somehow manage to mistype one of the fields (obviously, you never ever mistype, but some people do…). This mistake haunted me for long enough to get me motivated to solve it.

Apparently, the solution is very straightforward: just highlight the “wrong” value in the drop-down and hit Shift+delete to get rid of it.
