I suggest we go through the extension tag and disambiguate it.
- Move all browser-extension related questions to:
- google-chrome-extensions
- firefox-extensions
- safari-extensions
- et cetera
- Create internet-explorer-extensions in that process.
- Move all file extension questions to file-extension.
Anything that's left after cleanup should possibly have the tag removed, because if you're asking for extensions for X, it should be enough to just tag it X.
If there's enough agreement on that, let's go through that list and clean it up step by step.
