Web Browser Compatibility

Currently, we develop our web applications to work in conjunction with the World Wide Web Consortium (W3C) Specifications, Using HTML5, CSS3, ECMAScript 6.

As these standards evolve and new versions are released (such as the upcoming CSS4) browsers vendors will release updates to support the new features but do not create backward compatibility with previous iterations as they expect users to stay up to date. 

Internet Browsers

Because of this we only test our developments on the latest versions of web browsers because we cannot guarantee backward compatibility. 

 As of February 2020, the market share statistics are:

February 82.0 % 2 % 8.7 % 3.4 % 1.2 % 0.7 %

When we release our developments, we will guarantee support for the Latest version of:


Google Chrome (Current 80) (5th Feb 2020)

Mozilla Firefox (Current 74) (10th Mar 2020)

Microsoft Edge (Current 80) (7th Feb 2020)

Important Note

Microsoft recently abandoned Edge and rebuilt a new browser from the ground up using the Chrome source engine and gave it the same name of Microsoft Edge.

Microsoft Edge

If you still see the old logo you are not up to date. This update should download as part of Windows update but if it does not it can be manually acquired here:



Google Chrome for Android (Current 80) (5th Feb 2020) 
Mozilla Firefox for Android (Current 68) (3rd Sep 2019)
IOS Safari (Current 13.3) (28th Jan 2020)

It is very likely that the web applications will still work on many previous iterations of each browser but inevitably, they will become unsupported as time passes.

As such we strongly recommend that each company notifies and encourages their clients to update to the latest version.

Moving forward any further updates we do are very unlikely to still be compatible with IE as it is no longer updated by Microsoft.
