User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.7) Gecko/20050414 Firefox/1.0.3
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.7) Gecko/20050414 Firefox/1.0.3
If you put an onblur() event handler on an input box that creates an alert(),
then user the alt+tab combination to switch to another windows application, the
alert comes up when the window does not have focus. This seems to cause
problems for the browser as the alert cannot be dismissed easily, nor can the
browser window be closed.
Reproducible: Always
Steps to Reproduce:
1.Create an html page like this:
<html>
<body>
<h1>test case</h1>
<p>
<form>
<input onblur='alert("hi, mom")' >
<p>
<input onblur='alert("hi, sis")' >
</form>
</body>
</html>
2. Open page in firefox, windows XP (could not reproduce on my linux box)
3. Select one of the input boxes, enter some text
4. User alt+tab to switch to another windows application
5. Return to the firefox window and attempt to interact with window
Actual Results:
The dialogue could only be dismissed by using the escape key. Even then, I had
to alt-tab to a different application, then alt-tab back to firefox to actually
do anything on the form
Expected Results:
The dialogue should either not have been produced (no onblur on alt+tab to
switch windows) or else should have been dismissable as normal

This does not exactly act as told. I can interact with it. I only have a second
one appear. But when i dismiss the seconde one everything is ok. So this works
for me using Mozilla/5.0 (Windows; U; Windows NT 5.1; fr-FR; rv:1.7.7)
Gecko/20050414 Firefox/1.0.3

When using Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2)
Gecko/20050419 Firefox/1.0+ it gives i funny behavior then i tested again with
Mozilla/5.0 (Windows; U; Windows NT 5.1; fr-FR; rv:1.7.7)
Gecko/20050414 Firefox/1.0.3 and i get the bug. So finally i can reproduce this
: After coming back to firefox and dismissing the to prompts i cant click in
firefox unless i press escape. I get this in the two versions. Sorry for posting
to fast.

I have to ad that even if press escape sometimes it does not solve the problem
and I am forced to close.

Bug still exists in v. 1.5.0.1; slightly different behavior. Now I have to click "Ok" or hit escape *twice* to dismiss dialogue, then go to a different window and back.

But still exists in v. 3.0.6 - exactly as reported by Ben Drasin in 2006.

Marking this as Resolved > Worksforme since the issue no longer is reproducible on the latest versions of Firefox Nightly 95.0a1 (2021-10-19), beta 94.0b7 or release 93.0 on Windows 10. The message is dismissable by pressing OK or the escape button or Enter on any simple interaction.
If anyone can still reproduce the issue either re-open it or file a new one.
