User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:6.0.2) Gecko/20100101 Firefox/6.0.2 Build ID: 20110902133214 Steps to reproduce: Tried to (in the most recent 3, 4, 6 and 7 versions) - move a tab - create a bookmark by dragging the address from address bar into bookmarks - anything else that involves drag and drop Actual results: FF crashed without giving out any kind of error. The crash does not occur imediately after a mouse button is pressed, but after moving the mouse. In normal operation that's about the time when the transparent image appears. Expected results: FF should not have crashed ;).

Please provide a crash id or stacktrace -> https://developer.mozilla.org/en/How_to_get_a_stacktrace_for_a_bug_report Your user agent shows 6.0 - does the issue occur with Firefox 7? Does the crash still occur if you start Firefox in Safe Mode? http://support.mozilla.com/en-US/kb/Safe+Mode How about with a new, empty profile? http://support.mozilla.com/en-US/kb/Basic%20Troubleshooting#w_8-make-a-new-profile
Priority: P2 → --
Version: unspecified → 7 Branch
Just to clearify: The crash occurs with a new empty profile. I'm using domain logons and on a different PC with the same FF and same profile, the problem does not occur. That's actually the reason why I reinstalled the one particular PC on which the crashes occur and even the reinstall did not work. The crash still occurs in Safe Mode. I've also tried to manually block some plugins in order to see if a combination of those was causing this.

@Tim: You asked whether the issue occurs with Firefox 7. As I stated in my initial comment - I've encountered it in 3, 4, 6 and 7. It's possible it's also in 5, but I have not tested 5.
Please do not set the priority flag - this is only for use by the developers.

Please do not set the priority flag - this is only for use by the developers. "Domain logins" - what technology are you using for this? roaming profiles? redirected folders? other? Please attach the contents from about:support on the problem PC as a text attachment to this report
@Tim: I am sorry about the priority flag, I did not mean to change it. It's redirected folders actually, but there's no difference between local profile and roaming profile in the matter of this issue. The submitted stacktrace was recorded using a local windows profile.

Can you go to about:crashes, click on the link for your crash and then paste the URL here?
@Brian R. Bondy: When this crash happens there is no error message (no anything ;)) outputted (about:crashes is empty). The Firefox windows just disappears. The only thing I am able to get from it is the stacktrace from WinDbg.
The automatic crash reporter does not appear? Do you have Options->Advanced->General->submit crash reports enabled?
What graphics card is that? Do transparency effects work in other programs on that PC?
I have just found out, that this crash does not occur on the FF 3.X version line. Might be that there is no transparency effect used in those versions. @aceman: Yes, the automatic crash reporter indeed does not appear, even though it is and has been already turned on in the options. I believe it is also the default behavior after a clean install. It is an NVIDIA GeForce 8600GT graphics card using the current 280.26 drivers. Could you please point me to another app that uses the same transparency method as does FF so I can test it? I can for example drag and drop icons on the desktop (they turn transparent as well when you move them) and there the transparency works as expected - the icons are transparent when moving and stop being transparent when they're not moving and nothing crashes :D.
I can only think about Thunderbird as an application that could use the same transparency method as Firefox. You can at least drag & drop tabs in it (but I do not get the transparency effect). What about dragging images from webpages in Firefox? Does it crash too? Can you disable HW acceleration in Firefox (tools -> options -> advanced ->general). about:support does not show it as enabled, but let us be sure. It also does not show your Nvidia card. Why is that? I wonder what is that RDPDD graphics driver. Can you tell us anything about it? It seems to be something with demote desktop (RDP). Are you using that?
@aceman: That TB suggestion was actually useful - when I for example create a contact in address book and try dragging that contact to another contact group - the same crash happens. It's TB 7.0. Dragging images in FF has the same effect - crash :(. The about:support page shows RDesktop because I am actually logged in via remote desktop, because when I have time to get here (bugzilla) I am at home. But I can assure you that the crash still occurs no matter how I'm logged in. And the HW acceleration is acutally on. But turning it off or back on does not make any kind of noticable difference.
I hope you restarted firefox after turning HW acceleration off. And it crashes even with it off?
@aceman: What I did was - started FF - turned the HW acc off - dragged a tab -> ff crashed - started FF - turned the HW acc on, then off again (to make sure the change was actually processed) - quit FF - started FF - dragged a tab -> ff crashed - started FF - turned the HW acc off, then on again - quit FF - started FF - dragged a tab -> ff crashed BTW: Thanks a lot for your really quick replies ;) I really appreciate them.

Is the next line wrong? > - turned the HW acc off, then on again > - quit FF > - started FF > - dragged a tab -> ff crashed Could you please test it simply: turn HW accel off, close FF normally, start FF, drag a tab?
(In reply to aceman from comment #18) Yup, that was a typo. I actually turned it on and then off ;). I just did a clean install, turned it off, restarted and it still crashes.
Do you have any plugins enabled? Those were not listen on the about:support page, try attaching about:plugins if there are any.
I do all this under -safe-mode with everything disabled. ;)
Safe mode does not disable plugins.
Still, there are no plugins. about:plugins does not list any.
Maybe you could start Firefox from the command line and see if there are any messages after the crash. I am not sure if it puts warnings there on Windows as there are on linux.
I've already done that earlier in order to find something new, but I tried it today again anyway. There's absolutely nothing outputed to std output.
Petr -> Is this still an issue with Firefox 9.0.1? Are there any entries under about:support? Have you upgraded your drivers?
(In reply to Tim (fmdeveloper) from comment #26) > Petr -> Is this still an issue with Firefox 9.0.1? Are there any entries > under about:support? Have you upgraded your drivers? Hello Tim. Thanks for the heads up. I would have never tried updating if it was not for you ;). Fortunatelly, it seems that this is no longer an issue with the latest FF 10. Thanks a lot to all of you.

Thanks a lot to all of you. > > Closing as WFM - glad the issue is now resolved for you It seems to me that now FF does some checking before it tries to utilize transparency and therefore does not crash because it now acts the same as FF 3 did - no transparency when drag&dropping :)
