XPCOM

Use the JavaScript API instead of nsIDownloadManager as the back-end for the panel. nsIDownloadManager has now been replaced for Downloads.jsm. An announcement and discussion about this particular topic can be found here.
Remove Components.lookupMethod. This function is no longer necessary to use.
Don’t call into nsIAccessibleProviders. nsIAccessibleProvider was removed, so you should not reference it from your XBL bindings anymore.
Remove nsIHistoryEntry and replace it with nsISHEntry.
Remove memory uni-reporters. This changes the interfaces and implementations around nsIMemoryReporter.
Tabs are duplicated after going back to Firefox for Android. This changes nsISessionStore on Firefox for Android.
Refactor nsStrictTransportSecurityService. nsIStrictTransportSecurityService is now nsISiteSecurityService.
Mark nsIContentPrefService as deprecated in favor of nsIContentPrefService2.

Binary

Binary compatibility broken for maintenance releases due to strict version-script.
This is actually a fix that improves compatibility for binary add-ons. A
recent change made it more difficult for binary add-ons to stay
compatible because they needed to be rebuilt for minor version updates.
Make nsGenericHTMLElement implement nsIDOMHTMLElement. This is an internal refactoring that only affects binary add-ons.

DOM

document.getAnonymous* should not be available to web content. Whitelisted remote XUL should continue to work.
Hide XULElement from content.
Add deprecation warnings for mozGetAsFile. This canvas function is now deprecated, in favor of toBlob().
Remove support for chrome access to history[n]. This removes a few chrome-only, Firefox-only properties of the window.history object. history.current, history.next and history.previous were also dropped.

New!
