My “go to” desktop browser for doing web development is the Chrome browser. It’s got lots of cool plugins, and doesn’t crash as often as Firefox does (for me, at least).
However, it has one annoying problem for people like me who do responsive web development: It won’t resize down to 320 pixels wide, the width of an iPhone. With my Chrome browser on Windows, the minimum width is over 400px. On Mac, the minimum is 400px. This makes it a pain to quickly check mobile layouts during development. You can’t make the Chrome browser window thin enough!
Firefox, on the other hand, will get as thin as I need it to! But, It’s inconvenient to have to use two different browsers during development.
This works on Chrome for Mac and Windows. During development, I launch this once, and refresh it using the F5 key.
