Do a few of your favourite sites refuse to properly load in your favourite browser? Whether you're in love with Firefox or Chrome it seems like you'll always run into a few pages that refuse to render properly or you want to use an extension on. Switch is a simple menu bar app for Macs that lets you automatically open any tab in another browser with one click.
Switch doesn't do anything a quick copy and paste doesn't, but it does make things a bit easier. Simply set a default browser in the preferences menu and when you need to send an open tab to Firefox, Chrome, or Safari, left-click the Switch logo and it automatically opens it. You can also right-click and choose a browser if you prefer.
Switch comes in surprisingly handy when you're swapping between browsers because of rendering or extension issues. It's a free download from the developers site linked below.
