Browser Support Policy October 2019

Last Update: October 28, 2019

The following applies as a core set of browser support guidelines for our web site products. These guidelines can be altered for specific project needs as the team and client sees fit. Any alterations will increase, or decrease, the scope and time of a project.

tbk will endeavour to support modern, popular browsers back dated to a maximum of 2 years from the date the project begins, with certain exceptions as listed below.

As a general guideline, tbk provides physical testing in the browsers and versions listed below. However, not all tests are performed on physical devices. Those devices, which we test virtually (via a simulator) are noted below where applicable.

Based on the document’s last edited date, the following browsers and versions are supported as core browsers for all tbk’s website products. These browsers account for 90% of the browser market share, both desktop and mobile statistics combined.
