because you are editing javascript files FF and many other browsers will cache them - this is pretty much a default browser behaviour, the same way browsers cache images and CSS. For some reason web browsers seem to like to hang on to javascript files more than other file types though. Its not a bug in FCKEditor or ASP.NET related.
Can't say i've ever tried "kicking FF in the head and pulling the rug out from under it "...
The easiest way is to clear your cache in FF - Tools > Clear Private Data > (Cache Checkbox). Or use something like the Web developer extension for FF, which has loads of cache options.
