You seeing me as aggressive just because I'm right about Firefox being a web browser is nothing I can do anything about and something you have to work with.

Me and Mozilla will keep trucking and call Mozilla Firefox a Web Browser.... Or as Wikipedia says:

Mozilla Firefox, or simply Firefox, is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation.

And you keep calling Firefox your banana or whatever. It's ok. I promise to continue to not being aggressive about it.

Banana or not, a document viewer / editor that handle a subset of two standards is not a very versatile document viewer / editor.

So back to my original point: Since Mozilla doesn't have a very stable business model it seems dangerous to focus on other things than making their web browser the best at browsing the web.

Ps. It took us over 20 years to get rid of the cluster f***s Internet Explorer and Flash was and it seems we should have learned the lesson by now. Going down the same route as before, starting to support standards that rely on patents owned by a third party (Adobe in this case) is definitively not a death sentence in any way, but history has shown us that it's a slippery slope that has many different paths and endings.
