Lightbeam is currently implemented using jetpack and needs to be rewritten using web extension so that it can work in Firefox 57+. While we could in theory salvage some of the existing UI code, it has significant performance problems (see https://github.com/mozilla/lightbeam/issues?q=is%3Aissue+is%3Aopen+label%3APerformance and bug 1188507) and therefore would benefit from a fresh start. The scope of this bug is to build an MVP which includes the most important features of Lightbeam while leaving out the problematic ones. Included: - graph view linking pages to all of the third-parties resources they load - displaying the total number of third-parties found - internationalization (https://github.com/mozilla/lightbeam/issues/74) - tracking protection toggle - filter out Private Browsing loads (https://github.com/mozilla/lightbeam/issues/662) Not in the MVP: - list view - favicons (https://github.com/mozilla/lightbeam/issues?q=favicon+label%3Afavicons) - origin details sidebar - coloring edges to show the presence of cookies

BTW, I'm not sure which component this should be in, but being on Bugzilla seems much better than GitHub since we will likely want to depend on new Web Extension APIs at some point (though maybe beyond the MVP).

Luke has said he will spend an hour looking at this to provide a rough estimate of the amount of effort needed to do this rewrite.

A consolidated outline of functionality that would be needed, that doesn't exist in the webext APIs, would be great so we can consider those needs.

:francois - do we want to visualize only the 3rd-party trackers that would have been blocked by TP, or all 3rd-party trackers? :mixedpuppy - at minimum, we will likely need a new property on webRequest details objects. Something like: tracker boolean. True if the domain of the request is on the Disconnect blocklist. False if the domain of the request is NOT on the Disconnect blocklist.

Lightbeam only displays third-party loads, it doesn't attempt to infer tracking or not. So for the MVP (which is about not losing the existing Lightbeam functionality), we can completely ignore TP and the Disconnect list. > :mixedpuppy - at minimum, we will likely need a new property on webRequest > details objects. Something like: > > tracker > boolean. True if the domain of the request is on the Disconnect blocklist. > False if the domain of the request is NOT on the Disconnect blocklist. It would be nice to have this for MVP+1, but we don't need it for the MVP. One thing we do need for the MVP however is for privacy.trackingprotection.enabled to be added to the newly-landed Privacy API. That's needed by the TP toggle that's currently in the top-right corner of the Lightbeam UI.

Adding Bug 1342265 as a "See Also" as Francois mentioned it's not MVP, it would however make the extension smaller and not require shipping it's own lists.

Hi Francois, Are you actively working on the WebExtensions version? If yes, can we assign the bug to you and do you have an expected release date?

:shell we are working on this as part of Outreachy, work is about to begin next week on this. No expected date as of yet. Please pester me or pauljt if you have questions. Work will happen here: https://github.com/pauljt/lightbeam-we/issues

Adding tag so this bug appears on https://arewewebextensionsyet.com/

Hi Jonathan, Following up to see if there is an ETA for the migration of Lightbeam to a webextension completing. Beta 57 has gone out, and with it Firefox is running only webextensions.

Pushed! Bugs: https://github.com/mozilla/lightbeam-we/issues Support: https://discourse.mozilla.org/latest?tags=lightbeam Thanks for asking :shell, I had not forgotten. We ironed out the last minute issues today. Let's wait for the dust to settle before getting the featured extension badge back on.
