Search widget stopped working for specific search engine

[nafarinha]

Hi,

I use FogBugz from FogCreek and until recently I was able to add this search engine along with the Desktop add-on. But for some FF versions, it is simply impossible to add my FogBugz search engine to a search widget. Fyi, I've always created a search engine using another add-on, the Add To Search Bar add-on, version 2.8, when it worked with Desktop and now, that it doesn't.

Thanks,
