Browser Support & Web Development Policies
TDA is committed to making our website easily accessible and consistent across supported browsers and platforms. Because it is not always possible or practical for us to fully test and validate our website using every available operating system and browser combination, we have implemented these policies to ensure support for the majority of our users.
Moving forward, all current and future applications will be developed in accordance to these policies. However, we also have several legacy applications that were developed before these policies were established, and they are not fully compliant with these policies.
We are currently working towards bringing these applications into full compliance, and in the mean time, they will indicate which configurations are supported and/or any known compatibility issues.
In addition to developing applications and websites in-house, TDA sometimes contracts with third-party vendors to provide web-based applications; these applications may or may not be fully compliant with these policies. We are also working towards bringing these applications into full compliance.
To maximize our ability to successfully support our constituents' needs, and to enable our engineering teams to make use of new capabilities available in modern, up-to-date browsers, we made the decision to support only modern browsers, which also provide improved security and performance.
TDA also uses statistical data from web visitors and registered users, rather than generic industry data, to identify the browsers used by our target audience. We regularly review this data to determine which browsers to support. Our current policy covers over 95% of our users.
We support the latest version of Google Chrome (which automatically updates whenever it detects that a new version of the browser is available). We support the current and previous major releases of Firefox, Internet Explorer, and Safari on a rolling basis. Each time a new version is released, we begin supporting that version and stop supporting the third most recent version.
