On my wife's Macbook Air, I'm trying to find a way to get mailto: links to direct to Gmail in Safari rather than the stupid Mail app. It looks like there was an easy way to do that previously using an extension, but Apple isn't allowing third-party extensions any more.
Has anyone figured out a way to make this still happen?
Kinda rough but found a way to do it within Safari itself, like won't handle email links from other apps, and just goes to a compose page (doesn't open a new window...probably not too hard for someone that actually knows JS).
Used the javascript linked here:

In Safari, turn on the Develop menu in Preferences->Advanced, then Show Extension Builder from the menu. Use the plus button in the bottom left corner to add a new extension, then in the Finder, put that javascript file into the extension folder you just made. Back to the extension builder window, set website access level to all and include secure pages, and under injected content->start scripts, select the javascript file.
Then hit the Run button in the upper right...not sure if you have to do it every time you launch Safari though (course I rarely close it to begin with).
I wouldn't be surprised if there's a cleaner way to do it in Chrome with an extension there, in which case you might try that and just use it as a separate Gmail app. There's some apps on the App Store that might work too but haven't tried them.
