Jumplist

I found a way to disable custom destinations for a single app but it isn't very pretty.

1) Navigate to %userprofile%\Recent\CustomDestinations
2) Locate the .customdestinations-ms that corresponds to the app. I did this but sorting by last modified and basically guessing
3) Make sure your app (firefox) is closed and then open the file and delete all the contents
4) Mark the file read-only

This should prevent custom destinations for that particular app.

You're right Mister...an ugly alternative.

I will offer this nugget:

When my laptop DOES create a jumplist, it seems to only include .html files that I've opened from my hard drive. Otherwise, my laptop "Firefox" (pinned to the Start menu) ignores files I've browsed from the Internet.

Firefox 3.5.5 does not support custom jumplists. This means that Firefox itself is not populating the list. The list is being populated automatically by Windows through the common file dialog and SHAddToRecentDocuments API. The newer pre-release versions of Firefox do add custom jumplists and I'll assume they will have an option to turn them off before they release (I couldn't find it as of now).
