Mobilizer’s Responsive Web Design Chrome Extension

Dan Engel Commentary, Mobile Testing, Technical Brief

With one click, see how your website performs on actual mobile devices

Gotta design it, code it, QA it. Gotta diagnose bugs and obliterate them. Gotta make sure your website is delivering flawless performance on mobile, and you don’t have time to waste!

You Can’t Get No Satisfaction watching the clock tick away:

  • Pulling up mobile testing tools and waiting for them to load
  • Testing each mobile device individually, instead of all at once and comparing results
  • Cooling your heels as slow tests eat up the minutes

Yes, mobile marketing teams and web developers are committed to agile development. You don’t have time to fritter away on frustrating delays that might lead to your Nineteenth Nervous Breakdown. That’s why Mobilizer has released its mobile testing tool as a Chrome Extension.*

A One-Click Solution

Install the Mobilizer responsive web design Chrome Extension in your Chrome browser. Then, whenever you need to test your website across 14+ leading mobile devices, click the Mobilizer icon in your Chrome navigator bar and the testing automatically begins.

Mick Jagger famously proclaimed, “You can’t always get what you want,” but with its responsive web design Chrome Extension, Mobilizer delivers test results right to your browser in a mere 35 second, so you get “what you need.” Quickly compare the side-by-side screenshots to easily identify mobile UX issues that could cost you big.

For example, just spend 5 seconds looking at rollingstones.com. Sure looks awesome on the iPhone 5c, but on the 6s and 6, their call to action buttons overlap their main header. (See full test results here.)
