my arrow keys and other cursor controls no longer work after two firefox updates. I have rebooted, same problem.
Before the updates, when I clicked on a field to fill, I could down arrow and the previous entry would display. Then I could select it and hit <enter> and proceed. Now <PageUp> <PageDown> <Home> <End> and none of the arrow keys work. I have done a cold boot, and still have the problem.

You may have switched on caret browsing.
You can press press F7 (on Mac: fn + F7) to toggle caret browsing on/off.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
