If you experience problems with TinyMCE editor or any other javascript functionality, or are experiencing strange display anomalies all of a sudden, be sure to check that you don't have Skype extension installed for Firefox. It is poorly produced, and apparently has no idea of where it's allowed to replace stuff and where it should keep its hands off from.

If you install the Skype plugin, those fun little green blobs are stuck everywhere, including all places where they really shouldn't go.

I don't have the screenshot handy, but not so long ago when this last happened to me, Skype was so "helpful" that when I browsed SQL databases with PHPMyAdmin, it replaced all unix timestamps in the database with "call with Skype" icons. Apparently it munches up any and all number series that resemble phone numbers, and you really don't want that to be happening in the middle of your inline javascripts...

Steer clear of Skype Firefox Plugin to keep your web applications working well.

Here's an illustration of how Skype "integrated" itself into PHPMyAdmin... If there are any Skype developers reading this: Guys, this really shouldn't be happening! Do you have any idea of the potential damage this sort of careless string replacement can cause across the internets? And people will obviously be complaining to us application developers first. Please err on the side of caution, rather than aiming for maximum ownage.

Of course it's handy if you can give a call to Mr. Unit Updater at 1246475682 in case he messed up your site. Unfortunately the country prefix for Unix isn't available in the country dropdown.
