Debugging asp.net with firefox and visual studio.net - very slow compared to IE

Question

Debugging asp.net websites/web projects in visual studio.net 2005 with Firefox is loads slower than using IE.

I've read something somewhere that there is a way of fixing this but i can't for the life of me find it again.

Does anyone know what i'm on about and can point me in the right direction please?

Cheers John

edit

sorry rob i haven't explained myself very well(again). I prefer Firefox for debugging (firebug etc)

hitting F5 when debugging with IE the browser launches really quickly and clicking around my web application is almost instant and when a breakpont is hit i get to my code straight away with no delays.

hitting F5 when debugging with FireFox the browser launches really slowly (ok i have plugins that slow FF loading) but clicking around my web application is really really slow and when a breakpoint is hit it takes ages to break into code.

i swear i've read something somewhere that there is a setting in Firefox (about:config maybe?) that when changed to some magic setting sorts all this out.

Answer 1

Are you serious? One of the main reasons I stick to Firefox is because its so much nicer to develop with..

The live source update is awesome (view source > change code > rebuild > F5 in source)...

What is actually "slow".. I mean, the some browsers tend to be slower at rendering, but I dont see how it affects your debug time? As soon as the request is made, and your breakpoint is hit in the code, it stops?

Answer 2

bingo. found the article i read before.

i just changed my network.dns.ipv4OnlyDomains property in about:config to localhost. restarted firefox and now firefox performs the same as IE when debugging asp.net with visual studio (2005).

hope this helps anyone else that has the same problem.

Answer 3

"Alternative solution". Do the following in Firefox

1. about:config in the address bar
2. set network.dns.disableIPv6 to true.

Answer 4

Worked for me!

Thanks a lot!

Answer 5

For quick debugging try this..

Add Debugger.Break() into your code at an appropriate place.

Browse to the page in firefox (via localhost) if on local dev machine? and the Visual Studio Just in Time debugger should pop up.. select the currently open instance of Visual Studio and you can step into the code where every you want without having to start from the beginning or jumping to cursor.

Thanks! Works fine.

Answer 7

I have this same issue, but this solution did not work for me. Any other ideas?

Answer 8

I'm not sure if this is related or not, but I can't debug VS2005 Firefox at ALL anymore. When I Browse With and select Firefox, the screen is completely unformatted and everything appears in one column. It's like all CSS is gone, my background is gone, my swf is gone. But it works like a charm in IE7.
