These bugs all seem related: bug 84027, bug 83109, bug 83919, and bug 83626.

Steps to reproduce (copied from from bug 84088) 1. Open a new browserwindow 2. Notice that the urlbar has focus 3. Try one of the floowing operations * Use home/end/left/right * Try to paste using either ctrl-v, contextmenu or menu 4. Click somewhere in the webpage to make the urlbar loose focus 5. Click in the urlbar to give it focus 6. Try any of the operations in 3. In step 3 nothing works. You can move the cursor using the mouse but paste and keyboard navigation is broken. In step 6 everything works fine. This is actually a problem with all textboxes. Try for example to bring up the properties on a bookmark and note that the name field dosn't work until you refocus it.

Changing OS to all based on dupes.

This works for me now. This bug gathered five dups during its first few days, and was then silent for a month, so I'm guessing the problem was fixed. If anyone still sees this problem, please reopen.
