Every time a development team creates a new website, or rolls out updates to an existing site, they have to ask:

  1. Will a website work perfectly across all browser versions, especially older ones? How frequently does browser compatibility testing need to be done to ensure flawless UX?
  2. If a website or web-app has been developed for the current version of any browser, exactly how many of the older versions does it need to be compatible with? How does one test a website on older browser versions?

This article will focus on and discuss the second question in detail.

If a website is compatible with the current version of Firefox that’s great news. But it would be unreasonable to assume that all users will have updated their browsers at once. It is entirely possible, especially for older users to be more comfortable on an older browser version.

In this case, not ensuring that the website is compatible with older versions might lead to a significant loss in traffic, revenue and credibility.

So how does one test on older browser versions of Firefox?

Simple. Use BrowserStack’s Firefox testing option.

BrowserStack’s real device cloud lets you test on multiple versions of real Firefox browser. Just sign up for free, log in, select the required Firefox version and start testing your website. All browsers on BrowserStack’s cloud are installed on real desktop and mobile devices. Therefore, all tests would be run in real user conditions, with 100% accurate results, every time.
