Status: RESOLVED DUPLICATE of bug 273456

(Firefox :: General, defect)

Ok...First time bug report but I know it is a bug cause it happens in both Linux
and Windows.

I use a web page for work (on a VPN so I can't share it with you).  The page
triggers a plugin response with this code though:  <EMBED
SRC="/status/thresholdexceeded.wav" HIDDEN=TRUE AUTOSTART=TRUE> and the page
reloads every two minutes.

So have that open in a tab and open a new tab.  Now on the new tab start filling
out a form (like webmail etc).  Whenever the first tab reloads and triggers the
wav file to play the sound the form you are working on will stop responding to
your input.  You need to click anywhere on the form (except in the field you are
working on) and then back into the field you are working on to keep typing.

It basically steals the focus without stealing the focus.

I hope this can help resolve the problem as its really annoying.  Other than
that Firefox RULES!!! :)

Reproducible: Always
Steps to Reproduce:
1. Open a tab with a page that auto reloads and plays a wav file on reload.
2. Open another tab with a form on it and start filling out the form.
3. Wait for the first page to reload and play the sound.
4. See if you can still type in field on tab B without having to refocus the field.

Actual Results:  
The field is not responsive until you click out of it and click back in.

Expected Results:  
Let me keep typing like nothing had changed.  

I have no themes installed but I do have the Tabbrowser Extension
(http://piro.sakura.ne.jp/xul/_tabextensions.html.en) installed.

I believe I am using QuickTime as the plugin responsible for playing the sound.
 It would be the latest version from Apple.

I don't have anything that meets the requirements to test this out and see if it
works or not, but Tabbrowser Extensions has been known to cause multiple
problems, which happens to be why it is not listed on UMO or on
ExtensionsMirror.  TBE could be your problem.  To be honest, I had though that
embed tags didn't even work in Firefox.

I have setup a demo page that reloads every 30 seconds and plays a sound so
anyone can test it out (excuse the lame code, did it up fast):

Tristor:  I believe I tried it with no tab extensions and got the same result.

For clarification:  Open the demo page in Tab A, then open hotmail or something
like it in Tab B.  Now type anything into the subject line in Tab B but don't
leave the field (IE pretend to get distracted by the phone while typing the
subject).  Wait for Tab A to reload and play the sound at least once, now try to
finish typing your subject line in Tab B.

Most annoying.
