I'm sure some people find this feature useful -- any time you hit an alphabetic key, it opens the Find field and puts the focus in there. This changes your position on the webpage, which can be extremely frustrating if the webpage is long. It's not quite the same problem as in http://support.mozilla.org/en-US/questions/1137893; that entry describes similar behaviour when focus is in a text box, which I interpretted as a data entry field. If I'm wrong, then perhaps it does describe the same problem, and I apologize for the double post. In any case, I'm spending more time finding my way back to my place in a webpage than I am spending to mentally parse the content itself In fact, it's become almost impossible to do the latter because of the fragmented focus. Hopefully, there is a way to disable this feature? I'm using FF 49.0.1 on Windows 7.
