* Cleanup beforeunload handler after transaction is resolved
The notification window was updated to reject transactions upon close
in #6340. A handler that rejects the transaction was added to
`window.onbeforeunload`, and it was cleared in `actions.js` if it was
confirmed or rejected.
However, the `onbeforeunload` handler remained uncleared if the
transaction was resolved in another window. This results in the
transaction being rejected when the notification window closes, even
long after the transaction is submitted and confirmed. This has been
the cause of many problems with the Firefox e2e tests.
Instead the `onbeforeunload` handler is cleared in the
`componentWillUnmount` lifecycle function, alongside where it's set in
the first place. This ensures that it's correctly unset regardless
of how the transaction was resolved, and it better matches user
expectations.
* Fix indentation and remove redundant export
The `run-all.sh` Bash script now uses consistent indentation, and is
consistent about only re-exporting the Ganache arguments when they
change.
* Ensure transactions are completed before checking balance
Various intermittent e2e test failures appear to be caused by React
re-rendering the transaction list during the test, as the transaction
goes from pending to confirmed. To avoid this race condition, the
transaction is now explicitly looked for in the confirmed transaction
list in each of the tests using this pattern.
* Enable all e2e tests on Firefox
The remaining tests that were disabled on Firefox now work correctly.
Only a few timing adjustments were needed.
* Update Firefox used in CI
Firefox v70 is now used on CI instead of v68. This necessitated
rewriting the function where the extension ID was obtained because the
Firefox extensions page was redesigned.
Two important notes:
1. The time it takes to download is negligble compared to e2e test runs
2. Since we cannot use environment variables in CircleCI cache keys we
can't cache the download correctly and have it update when we switch
firefox versions—this isn't the end of the world because of point 1
