== Hello, I'm a Firefox Contributor! If you are experiencing the issue stated on the title, we need your help! == == We haven't yet discovered the true cause of this, so please DON'T ASK FOR HELP HERE! == However, we can use your help to find what is causing this and IMPROVE Firefox, if you let us give you a task that will provide us with valuable information! Before you reply to this, we need to confirm the details of this issue, DO NOT reply here if your issue doesn't match the following: * Happens every time that Firefox is opened. * Happens in Windows. Also, one of the following has to happen: * Firefox window is not responding just after opening Firefox and requires it to be killed on Task Manager OR , * Firefox window never shows up but the process "firefox.exe" is listed on Task Manager. If you have this exact issue, please reply with: * your operating system architecture (64-bit or 32-bit?) * a debugging session * your e-mail so we can follow up with you to ask you for more information. I repeat, we DON'T HAVE a solution for this, so please don't tell us you have the problem without giving us the data we ask, and don't make other unrelated questions. You might ask, how do you give us a debugging session? Instructions: *You need to install the following software, "Debugging Tools for Windows". Download it from http://www.microsoft.com/whdc/DevTools/Debugging/default.mspx (if you own a 64-bit version of Windows, follow the link on that page to the 64-bit version). Then install it, the standard settings in the installation process are fine *To begin debugging, run WinDbg from the Start menu. (Start->All Programs->Debugging Tools for Windows->WinDbg) Next, open the "File" menu and choose "Open Executable...". In the file chooser window that appears, open the firefox.exe executable in your Firefox program folder (C:\Program Files\Mozilla Firefox). *You should now see a "Command" text window with debug output at the top and an input box at the bottom. You will have to enter commands in that input box, COPY THEM as they are written, ONE BY ONE, pressing enter after each one of them (this is IMPORTANT): <br/> <code> .sympath SRV*c:\symbols*http://symbols.mozilla.org/firefox </code> <br/> <code> .symfix+ c:\symbols </code> <br/> <code> .reload /f </code> *Now wait a second, this might take a while... Copy the following commands after... <br/> <code> .logopen /t c:\firefox-debug.log </code> <br/> <code> .childdbg 1 </code> <br/> <code> .tlist </code> <br/> <code> sxn gp </code> <br/> <code> |* lm </code> *Now run Firefox by opening the Debug menu and clicking Go. Right after, Firefox should start running and the problem should happen again. As soon as you verify the problem is occurring, open the Debug menu and click Break. Then, copy these commands: <br/> <code> |* ~* kp </code> <br/> <code> |* !analyze -v -hang </code> <br/> <code> |* lm </code> *After these steps are completed, find the file c:\firefox-debug-(Today's Date).txt on your hard drive. Now, you have the data in that file, open it and copy the contents into a new pastebin URL at http://pastebin.mozilla.org/ * After creating the pastebin, be sure to save the CUSTOM url that links to your report. == Finally send us the data by replying here and indicating the URL of the pastebin, with the rest of the information we are asking above. == == Thanks for contributing with the Mozilla Development, you rock!
