Comment 5 for bug 417729

I am currently encountering this bug, and it occurs all the time that I run Firefox (not just after several hours). I updated Karmic Beta late on October 6.

Whenever my cursor is in a text field or the URL bar, if I hold an arrow key down, the cursor will move once, then freeze while the key repeat kicks in, and then when I let go it will abruptly leap to its destination (which corresponds to how long I held down the key).

From my experimentation, I find that this doesn't happen for other keys that repeat, such as letter keys or backspace. It doesn't happen when I use arrow keys for something else, such as moving the page. It doesn't happen in other applications I've tried besides Firefox, but it *does* happen in both firefox-3.5 and firefox-3.0.
