The following information is based on the (CC-BY-AT) Mozilla article for the same, found here at the time of writing:
Minidumps are files created by various Windows tools which record the complete state of a program as it's running, or as it was at the moment of a crash. Basic information about crashes can easily by collected by way of e.g. the AppCrashView tool, but sometimes that's not sufficient to diagnose a problem. Sometimes a more complete form of crash data like a minidump is needed to see additional details about a crash, in which case manual capture of a minidump is desired.
This page describes how to capture these minidumps on Windows.
Capturing the dump
To capture a full minidump for an application crash, you can use a tool called windbg.
- Download the Windows Debugging Tools and install the version version that matches your Pale Moon architecture. Even if you are on a 64-bit Windows, your Pale Moon might be a 32-bit one. To double-check, you can open Help → About in the browser, and look at the "Version" entry. If it includes the string "(64-bit)", then you need the 64-bit version of the tools, otherwise use the 32-bit version.
- Run WinDbg (Start → All Programs → Debugging Tools for Windows → WinDbg), and select File → Open. Choose the Pale Moon executable, called palemoon.exe, and usually found in "C:\Program Files\Pale Moon". (When running a 32-bit version on 64-bit versions of Windows, you may find it in "C:\Program Files (x86)\Pale Moon" instead.)
- From the menu, select Debug → Go, and Pale Moon should start. If the debugger spits out some text right away and Pale Moon doesn't come up, select Debug → Go again.
- When the program is about to crash, WinDbg will spit out more data, and the prompt at the bottom will change from saying "*BUSY*" to having a number in it. At this point, you should type:
(make sure it is an existing folder you have write access to. c:\mydumps is an example -- any writable location with sufficient free space should work)
Code: Select all
.dump /ma c:\mydumps\palemoon-crash.dmp
don't forget the dot at the beginning.
Once it completes, which can take a fair while, you will have a very large file at c:\palemoon-crash.dmp that can be used to help debug your problem.
A few important notes about the dump files:
- These minidumps contain the complete contents of program memory. They are therefore very likely to contain private information, if there is any in the browser. For this reason, you may prefer to generate minidumps against a clean profile where possible.
- Dump files are (very) large. It is important that you compress these files (e.g. using zip or 7-zip) before you send them over.
Alternatively, you can upload to our FTP server directly:
