* Remove references to preferences.open_links_in_private and preferences.private_search_suggestions in tests. These metrics have been expired and may be removed.
* Add ignores for performance metrics that have expired.
* Remove tabs_tray.cfr.dismiss and tabs_tray.cfr.go_to_settings telemetry probes.
* Remove metrics controller from signature and remove in tests
For details on the root cause, see the commit. We replaced the similar
proguard rules because:
- the key line was returning false instead of true
- the other line had the same outcome as the written code. I believe it
was a micro-optimization. Since perf seems fine without it, let's
remove it
I benchmarked this change on COLD MAIN first frame. We see an
improvement of 89ms:
- before: 1346ms
- after: 1257ms
(cherry picked from commit f74e63ceae)
Theoretically, this should marginally decrease the duration of our unit
test suite. In my testing, for 1 iteration each (i.e. noise is very
possible), the duration changed from 9m 32s to 8m 21s – a 71s
improvement.

To identify tests that were running with robolectric that didn't need to
be, I removed the @RunWith(FenixRobo... from all relevant files:
sed -i '' "/@RunWith(FenixRobolectric/d" app/src/test/**/*.kt
I ran the tests and discovered which ones failed from the Classes tab of
the index.html test result file. Something like:
tests = document.querySelectorAll('table')[3].querySelectorAll('tr');
failureElements = tests.querySelectorAll('.failures');
// TODO: extract the test names
Then I copied these results to a text file and compared them to all the
files that had robolectric test runners to figure out which ones still
pass:
comm -1 -2 failures.txt changed_files.txt > robolectric_not_needed.txt
And undid the changes to the failing files:
for i in $(cat robolectric_not_needed.txt); do git checkout $i; done
Then I removed the import statements on those files:
for i in $(cut changed_files.txt); do sed -i '' "/import.*RunWith/d" $i; done
for i in $(cat changed_files.txt); do sed -i '' "/import.*RobolectricTestRunner/d" $i; done
runner
