Firefox - Detected script lockup.
Misplacing a bulleted / numbered list can cause a script lockup. Tested on both
Firefox 22 and Chrome 28
Steps to reproduce:
- Navigate to [[Lauda Air Flight 004]] and open it with the visual editor.
- Click the "Lauda Air Flight 004" infobox and make sure it remains selected.
- Click the "Bulleted List" button. A list bullet is added to the article.
- Click right after the bullet that was just inserted. Now click the "Bulleted
list" button again.
Normally this would remove the bullet again. Instead of that both Firefox and
Chrome seem to lock up. Firefox will lock up entirely (All open tabs will
freeze) and eventually an unresponsive script error will be displayed.
Cancelling the script allows you to regain browser control. On Chrome the
lockup seems isolated to the tab where we edit Wikipedia, but it only offers
the option to close the tab after a while (Losing all changes)
In practice one would never want to add a bulleted list this way, but actually
"crashing" makes it severe enough to report i would assume.
