181203 - Keyboard focus can be lost on certain sites

Status: RESOLVED DUPLICATE of bug 183103

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Seb Tomasini]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3a) Gecko/20021120
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3a) Gecko/20021120

My mozilla is configured to start with a blank page. Keyboard focus defaults to
the URL bar. Entering in certain sites (see steps to reproduce) and hitting
return results in a keyboard focus that is lost, cursor keys do nothing, and Tab
/ Shift-Tab to try and restore focus do not help. Note this behaviour only
occurs with certain pages, and I suspect this has to do with Java applets which
are running on them, hogging and not releasing the keyboard focus (just my guess).

Reproducible: Always

Steps to Reproduce:
1. Fire up mozilla with blank startup page
2. type "news.bbc.co.uk" followed by return
3. keyboard focus is lost when the site appears, requiring a mouse click to
restore keyboard functionality

I have found this behaviour to happen spuriously within Mozilla; sometimes navigating a link will suddenly render the keyboard unusable. Tab/Shift-Tab only help some of the time. I'll attempt to get some more concrete behaviours up here soon.

I am seeing the problem now. No Mozilla keystrokes work at all.
This looks to me like it's because of the Java applet taking the keystrokes.
However, it's not a problem in IE.

This must be a DUP of either bug 120921, bug 160192 or bug 183103.
In fact, some of those look like DUPS as well.

In fact, bug 183103 mentions the BBC site specifically, so I'll mark it a DUP of
that.
