Ability to use Firefox as a swiss knife of programs

[mozillian]

Hey, i believe Firefox already has the ability to replace most programs out there on anybodies computer  such as html and pdf viewers, i believe that every program should be replacable by firefox and that the program should be written in such a way; like an image viewer (currently it's hard to view like albums etc. as you have to manually change between images) and firefox doesn't automatically pop-up in the "open with" section of computers to do much of the actions it can.

The small bowie knife offers the classic Bowie silhouette—clip point, crossguard, and pronounced belly—in a more portable and discreet size, usually with a blade between 4 and 6 inches. This version is ideal for everyday carry in rural settings, fitting comfortably on a belt without impeding movement. Despite its smaller stature, the small bowie knife retains the chopping and slicing efficiency of its larger cousins, making it a favorite among trappers and backpackers. Many small bowie knives feature leather sheaths with secondary pockets for a sharpening stone.
