^F does not open search (and other broken keys)

[Thom]

Since latest firefox upgrade, ^F (ctrl+F) no longer opens search. Instead, it scrolls to next tab. The edit meny still shows that ^F should search as one would expect.

In text boxes ^F however does work correctly, and advances one characters (unlike ^N, which seems to have been completely stolen, see https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1660380)

As I'm writing this, it also appears that shift+arrows no longer select text in text boxes, only move the cursor, so something is horribly wrong with the keybindings.
