Windows ‘Bug’: Windows cannot find [website address]

This post has been updated… READ UPDATE

Today I was updating my Windows Live Mail and once again as has happened many times recently I got a popup error message from Windows:

Windows cannot find ‘<website address>’. Make sure you typed the name correctly, and then try again. To search a site for a file, click the Start button, and then click Search.

Which is always followed by Firefox opening and going to the page which Windows just said it could not find. It gets to be an aggravating situation when you put time and money into a computer, you want it to work right, and not complain when everything is working ok.

The answers were found on the MozillaZine Knowledgebase article Windows error opening Internet shortcut or local HTML file – Firefox. Basically, dump problematic Firefox extensions, update the ones you want to keep, and some work in Folder Options > File Types.

I was surprised to find some of my extensions listed on the Problematic Firefox Extensions page due to memory leakage and/or excessive CPU usage. I removed the ones I could do without and kept the ones I was willing to deal with. Now that I’ve cleaned out some of that “computer sludge” and taken the steps in the MozillaZine Knowledgebase article I no longer have those error windows popping up and my computer just feels more agile.
