To close the Find bar click the X at the right side of the bar .....

Thank you, I am aware of that. However, my question is still unanswered.

I must have misinterpreted your question (sorry  !).

'Thought you were looking for an easy way to close the Find bar and simply hadn't noticed the closing 'X' .....

Reading your question again and again, I get the impression that you'd rather use an add-on to close the Find bar than to simply click the closing 'X' - I simply just 'don't get it' (again : sorry  !).

I hope somebody else will come to your rescue  !

Just one question though : you say that you want the Find bar to "behave similarly to Google Chrome " - how exactly is that behavior  ?

No worries! I apologize if I came across as short. Thank you for your good wishes.

Yes, an add-on would be great if what I'm looking for isn't possible within Firefox per se.

The behavior in Google Chrome is that after I Ctrl+F for something, if I click on a link in the page, the "find bar" disappears. So if I'm in Chrome and I Ctrl+F on this exact page for anything then click on any link, the "find bar" (I put it in quotes because it isn't a bar on the bottom like in Firefox but a little box toward the top right) disappears upon clicking the link. In Firefox, the find bar persists despite clicking the link.

A less than ideal workaround I've found in Firefox is to enable "Search for text when I start typing" in the options. Doing that gives a less fully featured find bar on the bottom that will disappear upon clicking a link or some sort of clickable element in the page. This is great, but the less fully featured find bar does not have the helpful options to go to the next found word (up and down arrow), highlight all, etc.
