This removes Fretboard. The goal is to reduce cold startup costs associated with loading the experiments on the main thread. We currently have two experiments frameworks in use and should only require one.
Cache the list of installed browsers. Calling `Browsers.all`
the application directly redundantly recalculates the list.
Accessing the list of installed browsers through this cache
will reduce that overhead.
* For #4977 - Support opening Fennec pinned website shortcuts in Fenix
Fennec's pinned website shortcuts are set to open the BrowserApp activity.
So we need a new activity alias to actually catch such Intents. Otherwise they
would open "org.mozilla.firefox/.App" without any way to inform that this is
the result of the user clicking on a pinned shortcut.
For actually checking if the newly received Intent is of a Fennec pinned
shortcut we introduce a new FennecBookmarkShortcutsIntentProcessor which will
prepare the Intent to open the shortcut's URL in a new tab.
* For #4977 - Don't keep IntentReceiverActivity on the back stack
For successive Fennec pinned shortcuts to create a new IntentReceiverActivity
and be processed as normal we need to not keep this as our task root.
* For #4977 - Test the FennecBookmarkShortcutsIntentProcessor
* For #7352: integrate highlightable browser menu changes
* For 7352: invalidate menu when reader mode availability changes
* For 7352: removed highlight from reader mode appearance per UX
* For #5334: added private custom tab processor
* For #5334 - Fixes up IntentReceiverActivity for handling intents
* For 5334: update styling for private custom tabbs
* For 5334: update tests to account for new processors
Note that two are still failing. These appear to be true failures, and will be corrected in a later commit.
* For 5334: fixes bug introduced by changes to IntentReceiverActivity
RCA: intent className and extra were previously set based on which processors matched, not which successfully processed. This patch reintroduces that behavior.
* For 5334: add tests for custom tabs processing
* For #5694 & #6054: Adds preference screen for toolbar
* For #5694: Adds changing toolbar position functionality
* No issue: Updates telemetry links to actually work lol 😬
* For #6054: Adds toolbar position to core ping
