I was looking for a keyboard shortcut to close the find bar in Firefox 49.0 on Ubuntu and arrived to this question:
How to close the search box in Firefox with a keyboard shortcut when this box is out of focus?
However, for some reason Esc won't close the Find bar even if it has the focus. It's a bit annoying when one wants to refocus on the web content.
Is there any special setting I am not aware of that's preventing me from using the normal workflow?
