If I don't have the necessary plugin, an embed with width and height defined 
doesn't get a "click here to get the plugin" box when the height is less than 

I don't know what happens if I do have the plugin installed, andI haven't 
compared Mozilla to other browsers here, so this bug may be invalid.

Note that some space is reserved for the plugin in the second testcase, we just 
don't get a box.  I can't tell whether the empty space is clickable.

It is clickable. I think this behaviour (good or bad) is no different from 4.x. 
We have nothing to do with small space devoted to the plugin. Theoretically, it 
can be 1 by 1 or even 0 by 0. The good thing though is that the pop up saying 
that you need a plugin shows up automatically without clicking when the given 
mime type has never been seen yet. To test this you may open the registry key 
HKEY_CURRENT_USER\Software\Netscape\Netscape Navigator\Default Plugin and remove 
the appropriate mime type from the list.

Marking invalid. If you have other considerations please feel free to reopen it.

I'm not seeing a popup on either testcase using ns4x or mozilla.  Am I supposed 
to?  I'm also not getting anything when I click the box or the blank area.

Yes, you are, when you click the box or blank area in the second test case. It 
should be either JavaScript or native dialog box depending on whether you have 
JavaScript enabled. I see them on my 4.x installation. Make sure you have 
npnul32.dll installed in the plugins folder.

I don't see them on either browser, and I've tried with JS both on and off.

Do you see Netscape Default Plug-in when you do about:plugins?

ns4.75: yes, at the bottom there is a "Netscape Default Plug-in" entry.
mozilla: nothing happens when i press enter in the location bar.

(i'm confused about what the expected results for various things are in each 
browser.  is this supposed to work with mozilla as well?  am i supposed to see 
a pop-up in just ns4x or both browsers?)

The URL (link on ns4x's about:plugins) loads 
for Mozilla but not ns4.75.  Weird.

Ignore my previous comment.  I have set to and I was 
too lazy to make my test web server give me an identifiable error page.

Bug 48483 might be related... one commenter on that bug was having trouble with 
the default plugin on Windows as well.

The problem of nothing happening (no pop-ups, nothing happening when I click on 
the box) keeps going away and coming back as I play with the feature.  I 
haven't quite figured what makes it go away and what makes it come back.  
Adding type="video/quicktime" (bug 44692) to the testcase with the box might 
have something to do with making the problem go away temporarily, but I can't 
figure out what makes it come back.  I'll file a new bug for this soon; in the 
meantime, please don't verify this as invalid.

If I delete the registry entry, the box becomes "click here after installing 
the plugin" instead of "click here to get the plugin" for the testcase that 
shows the box, and both testcases give me pop-ups.  But if I hit reload, the 
popup doesn't come back.  This is wacky becuase "cancel" should not be 
synonymous with "go away forever", and should get a separate bug.

Restarting Mozilla also has something to do with making the problem go away and 
come back.

Comment 15

I can't reproduce the problem with "cancel" being permanent, so it's probably 
just another unintended, intermittent part of this bug or related bug and not a 
misdesigned feature.

I am kinda lost here. Could you please state exactly what the problem is i.e.: 
what is the observed behaviour and how it is different from what is expected and 
what are exact steps to reproduce it? I keep trying it myself and don't see 
anything contradictory, so this is either different factors which I don't have 
or just simple misunderstanding. If you have resources could you also try this 
on NT?

Shrirang, looks like this is strictly Win98 specific, if you can devote a cycle 
at this time could please confirm and reopen if necessary?

Comment 18

And will be great if you can compare Mozilla and 4.x in this respect.

Comment 19

sure, I will try this with a new build and comment.Thx

I have tried this. My results are:
I see no different behaviour between mozilla and 4.72 on windows wit hregards to 
both testcases. The frst one does show up the puzzle icon while the second one 
does not. If I remove the reg entry for the mime type (movie/quicktime) then I 
see the dialog pop up automatically.Also, the blank area in the second testcase 
is clickable. The plugin download dialog not popping up on seamonkey might be 
another bug, bug 44692. I am marking this verified since the original problem 
reported is invalid. David, pls open any new bugs for other problems tha toyu 
have mentioned in this bug report. Thanks !

Thanks, Shrirang. Just one question to make myself relaxed: did you try it on 

Comment 22

18 years ago
Yes, Andrei, I verified this on windows NT and Win 98 (build 20000920m18). All 
seem to have the same behaviour (4.x, seamonkey on NT and 98)

This still doesn't work for me on ns 4.75 or mozilla...

When playing with this bug, I have the following on my desktop:
- Shortcut to a Mozilla build with -console
- Shortcut to installed Netscape 4.75
- Second attachment, saved
- Modified version of second attachment with type="video/quicktime"

I also have regedit open so I can kill the video/quicktime = none entry when it 

When Mozilla doesn't bring up the popup, it doesn't do anything to the 
registry.  When it does, a key of video/quicktime = "(none)" shows up.

When the popup comes up, I see "Document
bin/plugins/get_plugin.cgi?mimetype=video/quicktime loaded successfully" in the 
console window.

I can't find a predictable pattern of when the popup comes up and when it 
doesn't, but it's not simply random -- there seem to be streaks of working and 
not working.  It comes up more often with the version of the testcase that has 
the mimetype defined, but still not always.  Restarting Mozilla often makes it 
jump from working to not working, but not aways.

I think the height=35 testcase behaves similiarly.  Netscape 4.75 also doesn't 
bring up the popup much of the time.

I'm mostly testing with Mozilla build 2000091808 because newer builds are 
crashing on exit, but I have noticed the popup not appearing on a newer build.

Created attachment 73300 [details]
A MIDI file used to create a non-404 embed src

On 2002030604, I see no box for either test case, but when I right-click in
the space where I expect the box to be, I get nothing.
Reason: The plug-in data now gives 404 because the original movie has

I'm working on a new test case that includes this MIDI file.
Loading a MIDI file from a Bugzilla attachment should be less likely
to link-rot than loading from some free web host, correct?

Created attachment 73306 [details]
New test case linking to attachment 73300 [details]

This test case uses the MIDI file from attachment 73300 [details].
It includes six EMBED elements, with heights 16, 32, 34, 35, 64, and 128
It obsoletes the first two attachments, which use "attachment 404 [details]".
Make sure to turn off QuickTime and Crescendo when trying it out to make sure
the default plug-in is called.

When I click in the area where the box *would* be, it puts up the proper
dialog for the first click (and then ignores all subsequent clicks).
See bug 115396 for left-click vs. right-click behavior.

Recent nightly builds still misbehave as originally described.
I suggest reopening.
