WebExtensions pageaction support ended?

Hi everyone,

We use in our Turn Off the Lights Chrome extension the pageaction to shows our gray lamp button to the users. Recently Google Chrome stop the support of ‘pageaction’ (icon in the omnibox / URL box). Now is all the extensions in the toolbar.

Will Mozilla Firefox follow also this rule to stop the ‘pageaction’ icon in the URL bar for the ‘WebExtensions’?

Thanks,
Stefan
