Firefox preferences for debugging and debugging methods

1. which preferences could be changed in a not-debug Firefox build to
improve debugging? Currently I know only

2. Do those preferences slow down Firefox? If not, why don't you
enable them by default for nightly builds?

3. Is there same smart methods and/or programs to debug Firefox? For
now I know only WinDbg and --console parameter.

I also have javascript.options.strict set to true, but it's not nearly
as important a preference as the one you mentioned for testing.
I also have layout.css.report_errors set to false, just because it's
flooding the error console too much.

I don't think so. That might be a good idea.
I see you filed for it.

I use VC Express, I like it more than WinDBg for debugging things.
I also use it to build Mozilla: might give you some ideas.

I use the dom inspector a lot to find why something displays badly or
to make minimized testcases.

The javascript debugger might be a useful tool to you, although I
never have understood how to make use of it.
I sometimes use LiveHTTPHeaders if I want to know which headers are
being sent/received.
I guess Firebug might be useful too (although I never use it).

How to debug Debug Why/When sessions expiring
Hi, I have a web application which has been migrated to .net 3.5. the user sessions are expiring at random (so it seems) without any rhyme or reason. We have the forms and session timeouts to 99999 and still no luck. Is there a way to debug this problem? It almost has the same symptoms as when you change the code in the app_code folder but in this case nothing has changed. Any ideas on how to go about it is greatly appreciated.  Ideally changing framework 2.0 to 3.5 shaould not cause any problem, because, base of 3.5 is 2.0 only, so nothing is changed just additional functionali...

Debugging in Firefox
Hi, I am developing an web application that has some SVG content in it. When I debug in IE, the application works fine with Adobe SVG viewer installed in IE and I can see my SVG content in the browser. Firefox has built-in SVG support but if I run the same application in Firefox, a dialog box "Open with" pops up to open up the SVG document and I can no more do anything in the browser. I tried opening just the SVG file (with still the http://localhost:.. as the path) in firefox and it still doesn't work. But If i open the SVG document with its original file location i...

debug.dump and debug.trace
Woah hold your horses.  Where did debug.dump and debug.trace go?  No compile time checking, poor debugger support and now I have to create my own debug.trace?  I hope this comes back in the next release or javascript will drive me completely insane.  I know I know it's not difficult to write one but that's not the point, if there is an assert why shouldn't there be a trace and a dump?  They worked so great. Sorry for my circular thinking.  I just can't believe my eyes that these are gone.  Regards,Alex Osipov Debug functionality will ...

Debugging with FireFox
Hi everybody,I am wondering how you're usually debug the application? I'm having problems debugging it with the FireFox (my default browser). For some reason, when I run a page with GridView and press Update button (which, BTW, is supposed to be a picture and works correctly in IE or in the live version of the app), nothing happens. The Update button remains Update, but there are no errors, nothing. It works correctly in IE or in the live version, it just doesn't work in Debug mode for some reason. Do you have ideas what may be wrong? Thanks in advance.   ...

is there a way to debug server controls?two wrongs don't make a right... but three lefts do! Certainly. You need to start with a debugger. I use Visual There is also the DbgClr.exe app described in the .net documentation. I will give an overview of VS.NET: 1. You must have access to the source code and project files of any server control. 2. Add the server control project to your web application solution. 3. Update the reference from the web app to use the server control project instead of the server control's assembly. 4. You can setup breakpoints in the server ...

How can I determine what is causing the server to go into debug mode? By debug mode I take it to mean the server abends? Try loading the server in loadstages.
