Features to document

1. Removal of AppCache

Related Gecko bugs

1. • Disable appcache in release — nice to finally get rid of this! We mainly just need to update BCD, and think about if there is anything else we want to remove.

For folks helping with Firefox-related documentation features — make sure above AC have been done, but also:

• Set bugs to dev-doc-complete
• Add entry to Firefox release notes if feature is enabled in release
• Add entry to Firefox experimental features page if feature is not yet enabled in release
