165546 - Possibly dangerous behavior with error reporting

Status: VERIFIED INVALID

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

Description

[bruce sherwood]

I was using my wheel mouse to scroll through a page. Pressing the wheel
(instead of rolling it) causes me to jump up or down in my URL bar history list
and go to what ever site I stop on.

This is not the problem. (i don't care about that feature.)

The probelm is I got a very bizzar dialog box containing content from the web
page I had been reading as well as the actual dialogs error at the bottom (page
not found).

I have a screen shot of it I can mail someone who wants to see this.

Pressing the wheel triggers a paste into the content area, which we treat as a
request to go to the url currently in the clipboard.  If the thing in the
clipboard is not a url, you get the dialog box you see (the text is treated as a
url and of course not found).

This is the same behavior as Netscape 4 on Unix had; you can disable it via:

user_pref("middlemouse.contentLoadURL", false);
