> Shouldn't this just be email serving domains? That was my initial idea, but then I realized that it can work in more places than I ever would have guessed. And I/we wouldn't have discovered them if it were only whitelist-enabled. You can see dozens of the sites here, and there are surely many more: https://github.com/adam-p/markdown-here/wiki/Compatibility https://github.com/adam-p/markdown-here/wiki/Compatibility > Also it'd be great if the Chrome webstore could offer some verification I agree, in principle. Unfortunately, it wouldn't match. At some point Mozilla decided to start rejecting updates because there was unreachable -- Chrome-only -- code in the extension. So I had to start using a preprocessor during builds to strip out platform-specific stuff. (AMO's reviews have driven me nuts over the years.) The build is reproducible, though. I also provide instructions for running the extension directly from source. Chrome makes it easy (Firefox doesn't). https://github.com/adam-p/markdown-here#manualdevelopment https://github.com/adam-p/markdown-here#manualdevelopment (I just realized that I need to update the Firefox instructions/link for WebExtensions. Which is even more painful than XUL was to use from source.)
