Canary uses Google's updater which won't work unless it's installed. Firefox's updater works just fine portably, so you can update your copy of Firefox Portable Nightly without having to re-run the portable installer to download a fresh copy. While Firefox Portable makes a great test bed for testing your site or extension with upcoming Firefox, Canary packaged portably would be a poor choice for each due to the aforementioned barely working notes. And the portable version of Chrome barely works portably with about 5 different big caveats listed on its page due to the portable-hostile coding decisions. The Chrome team would never accept a patch based on a reported bug in an unofficial portable package.

Mozilla, on the other hand, makes patches specifically to ensure portable use continues working well. It has multiple coding choices that make it openly hostile towards portable use. Unlike Firefox, Google's Chrome is not optimized for portable use.
