If you're sick of hitting an email link only to see your old email client open up on your desktop, Chrome has finally built in Gmail support, so links to email addresses open up right in your Gmail inbox.
To enable the new feature, just head to Gmail in Chrome. Starting today, you should see a popup at the top of the window that asks if you want to allow Gmail to open all email links. Click "Use Gmail", and you should find that any future email links you click — the ones that start with
mailto: — should open up in your Gmail inbox instead of a desktop mail client (no browser extensions or manual hacking necessary). If you're a Firefox user, you can enable this feature in Firefox's preferences. Hit the link to read more.
