Context
We don't need the polyfill except for async message handlers in background.
Changes proposed in this pull request
Remove polyfilled browser from content scripts and React apps to reduce bundle size, and have less JS in content scripts (as they get injected into each frame in each tab) for better performance.
Keeping it draft until we add more E2E tests.
Zip size went down ~23KB only (duplication compresses better in zip). Unzipped size went 2.09MB from to 2.03MB (60KB).
Tested manually in Chrome, Firefox and Safari.
