All of the browsers that GPT supports release regularly and
update automatically. Due to this, we don't maintain a comprehensive list of
supported browser versions. Instead, we validate GPT against
the latest version of each browser, and commit to providing support for all
versions that are officially supported by the respective browser vendors.
Unsupported browsers
The GPT library makes a best-effort attempt to serve ads to
any browser that loads it. This means that GPT works on
most browsers built to modern Web standards. However, browsers not expressly
listed in the preceding section are considered unsupported.
GPT hasn't been validated against unsupported browsers, and
they may lack features GPT needs to operate. In general,
GPT doesn't try to detect unsupported browsers or alter its
behavior to support them. If you use GPT with unsupported
browsers, you may encounter unexpected behavior like the following:
