In addition to our brief update on extensions in Firefox 83, this post contains information about changes to the Firefox release calendar and a feature preview for Firefox 84.<\/p>\n

Thanks to a contribution from Richa Sharma, the error message logged when a tabs.sendMessage<\/code> is passed an invalid tabID<\/code> is now much easier to understand<\/a>. It had regressed to a generic message due to a previous refactoring.<\/p>\n

End of Year Release Calendar<\/h3>\n

The end of 2020 is approaching (yay?), and as usual people will be taking time off and will be less available. To account for this, the Firefox Release Calendar<\/a> has been updated to extend the Firefox 85 release cycle by 2 weeks. We will release Firefox 84 on 15 December and Firefox 85 on 26 January. The regular 4-week release cadence should resume after that.<\/p>\n

Coming soon in Firefox 84: Manage Optional Permissions in Add-ons Manager<\/h3>\n

Starting with Firefox 84, currently available on the Nightly pre-release channel, users will be able to manage optional permissions of installed extensions from the Firefox Add-ons Manager (about:addons).<\/p>\n

\"Optional<\/p>\n

We recommend that extensions using optional permissions listen for the browser.permissions.onAdded<\/code><\/a> and browser.permissions.onRemoved<\/code><\/a> API events. This ensures the extension is aware of the user granting or revoking optional permissions.<\/p>\n","protected":false},"excerpt":{"rendered":"
