User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:90.0) Gecko/20100101 Firefox/90.0
Steps to reproduce:
- Put the "Library" button on the toolbar
- Go to about:newtab
- Click the Library button
- Click "Bookmarks" or "History"
- Click the back arrow
Actual results:
After clicking the back arrow and returning to the top level menu, none of the other options are clickable. Additionally the rest of the browser seems to be non-responsive. This does not seem to happen in normal tabs.
Dragging the window around my desktop seems to unfreeze the browser.
Expected results:
Clicking back into the top level menu should not freeze the browser, and the other options should be selectable.
It actually does happen in other tabs that are not about:newtab.

Unfortunately I cannot reproduce myself, though 1705085 looks related. Can you collect a profile of the hang with the Firefox profiler? https://profiler.firefox.com/

This is almost certainly bug 1701451.
