Why are certain features deemed uncompatible when upon forced installation...they work?
All revisions since 3.0 do not load foxkeh theme,foxkeh everywhere,lolifox,etc.because they are deemed incompatible. When a forced installation is done using nightly tester tools, lo and behold! they work just fine!! So what makes these add-ons incompatible? Who determines this, using what criteria?

It is down to the author of the add-on to indicate what versions of Firefox the add-on is compatible with. It is quite common for the author to stop working on an add-on, it may still work in later versions of Firefox but it is never updated to show that it will work.
I would not try making themes work with later versions of Firefox, themes have to be updated to work with later versions.
