Attachment: screen.jpg

User Agent: Mozilla/5.0 (Windows NT 5.1; rv:5.0.1) Gecko/20100101 Firefox/5.0.1
Build ID: 20110707182747

Steps to reproduce:

1) Open www.quartz-tools.com
2) Press the About button at the menu
3) Press the "Go back one page" button at Firefox or the mouse button to go back

And two:

1) Open www.quartz-tools.com
2) Press any of the video tutorials at right column
3) Press the "Go back one page" button at Firefox or the mouse button to go back
4) Move the mouse wheel while the page is loading


Actual results:

In the first case the menu doesn't work anymore. An icon hand appears in all the flash content. If a window is superimposed, the content is unblocked.

According to the problem two, the second swf object doesn't load, it appears a white frame. This is harder to reproduce, but when it happens is like in the attached image.


Expected results:

Displayed correctly.

[Matthias Versen [:Matti]]

Can you reproduce that without addons (safemode) ?

Comment 2

[Ed]

Yes, disabling all plug-ins less Flash and addons it still there. It should happen also in Linux.

I can confirm this on the latest nightly. Verified on Win XP, Win 7, Mac OS X 10.6  and Ubuntu 11.04. Firefox freezes after pressing the back button.

Setting resolution to NEW.

STR2 is not clear for me.

> 4) Move the mouse wheel while the page is loading
The page appears without loading activities after I click Go Back button.
'while the page is loading' is not clear.

Thanks a ton Alice, as usual!

Steven, see comment #7.

Comment 10

Trying to reproduce it better, I discover that happens simply pushing the middle wheel button, the one that locks the screen for scroll. But the frequency is very low, almost never and this time I have tried dozens of times. Passing some time it was impossible until reboot. The connection that I use is 1Mb, maybe it's a relevant factor or perhaps is only in this machine.

Attachment: Possible fix

Here's a possible fix for this bug.  And here's a tryserver build made from it:
http://ftp.mozilla.org/pub/mozilla.org/firefox/try-builds/[e-mail]-155c1c6a3928/try-win32/firefox-9.0a1.en-US.win32.installer.exe

Those who can reproduce this bug, please try my tryserver build.  If it fixes the bug, then my patch for bug 627649 did trigger it.  (Though my patch may just have uncovered some unrelated problem, which is the true cause of this bug.)

If this bug still happens with my tryserver build, then my patch for bug 627649 is (probably) completely unrelated.

Comment 12

[Ed]

The first one doesn't appear anymore here, but the second remains. Please see the attached video, the sequence is there.

I cannot find any problem in the video.

[Ed]

Did you solve it?

Comment 16

[Benjamin Smedberg]

Resolving old bugs which are likely not relevant any more, since NPAPI plugins are deprecated.
