This is a very odd and very narrow issue, but it's been driving me mad lately.
When I hold down the Backspace key to delete multiple characters, it only deletes the first character and then hangs.
However -- the kicker -- this ONLY happens in Firefox, this has ONLY happened on one site so far (Facebook), and this ONLY happens when I am replying to a post and trying to backspace in the little comment box.
Repeatedly single backspacing works fine. Facebook in IE works fine. Other similar commenting platforms (Disqus, etc.) work fine. Malwarebytes came back clean. The problem persists when I disable all addons in Firefox, and the problem also persists when I change "Page Style" to "No Style" under the View menu.
I wonder if this would be some rendering bug between Facebook and Firefox, or if it might simply be time for a new keyboard. But if it were my keyboard, shouldn't this happen in all sites and shouldn't this affect single-Backspacing as well?
Any advice or leads for this very obscure issue would be greatly appreciated. This may seem like the tiniest nitpick of a problem, but it affects me multiple times daily.
