I've found a curious behavior with a similar test page and steps: 1. Install build (so that Accessible Handler Used is TRUE) 2. Launch NVDA (and update to 2022.4) 3. Launch Firefox (with a new profile, CTW is off in beta and release). 4. Load https://en.wikipedia.org/wiki/World_War_I and scroll the page to observe when it becomes responsive. Exected: The browser does not freeze and it does not show performance issues. NVDA reads the page. Actual: The browser freezes for as long as a minute and then, it also shows performance issues for a few seconds. The curious part is that Beta MSIX build shows a longer freeze and UI stutter until it behaves as expected: - Beta v110.0b8 MSIX: a ~1-minute freeze and ~30-second UI stutter while scrolling the page. (Performance Profile: https://share.firefox.dev/3DyRTE9 ) - Beta v110.0b8 exe install: a ~15-second freeze and ~20-second UI stutter while scrolling the page. (Performance Profile: https://share.firefox.dev/3WTptM8 ) Jamie, should I log a new bug with this?
