[Feature Request] @FF Addon : Integrate (or build and redirect to) an online difftools for instant code comparison with previous version

[T1nFu]

sure crxviewer is extremely useful before installing a new addon (I'm using it on FF only).
But most of my usage stems from when I'm about to update any given addon. This is where crxviewer should shine most in my opinion. For any given addon/extension installed from AMO, and updated through are browser, being able to see the actual code change from previous version against the one we're being pushed an update from, would be an immense lever and overall responsible addons usage/"hygiene"..

There are many such online difftool available that accept zip file already..
I can't see of any better way to review the safety of any addon's update we're being pushed at. Doing so manually could be allevieated a lot with such a feature integrated to crxviewer.

This would be a useful feature. As a reviewer on AMO, I already have access to a (simple) built-in diff tool. For anything more complicated I download the zip/xpi files and perform a local diff.
