Mozilla does have a habit of rejecting code like WebDB/SQLite and PNaCl, so people are always surprised to see them reusing code, especially from Google.
I didn't know they had a history of rejecting SQLite - what are you referring to?
They have used SQLite to store bookmarks since Firefox 3: http://kb.mozillazine.org/Places.sqlite
But that doesn't mean they haven't rejected it elsewhere. Was just curious.
Edit: I see now. The WebSQL de-facto standard, which Mozilla rejected, essentially said: "use SQLite." Here's a discussion: https://plus.google.com/+KevinDangoor/posts/PHqKjkcNbLU

Those weren't rejections of code as much as they were rejections of specifications and features.
That's what open source is about: collaboration instead competition. Why compete when you can pool your resources together.
