I have searched the internet for the Source Code of Mozilla Firefox, but the feedback was not positive. Firefox is not on Mozilla's GitHub page. Where is the source code of Mozilla Firefox hosted?

Chosen solution

The source code for Firefox is not stored on GitHub. Instead, they use a similar tool called Mercurial. You can find more information about the Mercurial program by using this link:

https://firefox-source-docs(dot)mozilla(dot)org/contributing/vcs/mercurial(dot)html

Mozilla also has a service called Searchfox that allows you to search through specific parts of the Firefox source code.

NOTE: Due to some spam on the forums, posting links is currently restricted, so I had to substitute the dots in the link with (dot) in order for the forum to allow me to post it.
