Affecting Fetch API and Service Worker Cache API added several global objects

Published: | Categories: DOM


Starting with Firefox 39, the new Fetch API has been enabled by default. This API has implemented the Headers, Request, Response interfaces as well as the fetch method, so that you can no longer use those names for your global variables. Dailymotion is known to be affected by this change, because the site had its own Request object.

Firefox 39 has also implemented and enabled the Service Worker Cache API on the Aurora and Nightly channels, so you may have to be careful with the new Cache and CacheStorage interfaces as well.
