@Sdaswani: Need an engineer to do a technical analysis and provide possible options

[Sdaswani]

Sure @bbinto the research should be sprint planned, feel free to decide when to have an engineer do that.

There is still debate whether Reader View should be implemented in A-C or GV.

Here is the GV bug for Reader View:
https://bugzilla.mozilla.org/show_bug.cgi?id=1509257

Here is the A-C issue for Reader View:
mozilla-mobile/android-components#1346

Here is the R-B issue for Reader View:
mozilla-mobile/reference-browser#152

@snorp suggests that Reader View be implemented by A-C using a WebExtension to inject Readability.js as a content script.

@snorp suggests that Reader View be implemented by A-C using a WebExtension to inject Readability.js as a content script.

Note that if that is the preference then this is a large project for A-C and we would have to discuss timelines and priorities.

We will have at least a dependency on GV for providing the API for loading WebExtensions (looks like this work is happening already) and the WebExt API for having a communication channel between extension and app code.

@pocmo is there an estimate if we implemented this in AC?

[pocmo]

Not yet. But we can start breaking the linked A-C issue down based on snorp's suggestion.

As per comment, we might pull this back into a Battery saving story after MVP, however it should land for MVP as an individual feature.
