Is there a way to export the network data to say a pcap, from the Firefox Developer Tools Network tab? I haven't seen an option, but this would be really useful in sending issues to others.

I have some performance issue in an web app developped on a secured enterprised network. Internet connection is not available.
And since some version of Firefox, the performance tool send me to something like "https://profiler.firefox.com/from-browser" that, of course, is not accessible.
How can I analyse performance issue with no internet connection ? (Offline tool or an anlternative to firefox performance tool ?)
I need tools to test page load speeds for websites which are hosted locally on a LAN, and which are not accessible via WAN connections. In the past I was using Firefox with YSlow and Page Speed which helped me a lot, but since the latest Firefox version (in my case 39.0) YSlow is buggy and Page Speed disappeared from Firebug.
Any new tools which can be installed to do these performance tests?
I'd suggest Yslow from the command line if you're finding the plug in buggy. I'd also suggest Google Chrome Developer tools as an alternative to Firebug.
Try using firebug
plugin for Firefox , see the Net tab.
or
inspect element (Ctrl+shift+i for windows) , the Network tab on Google Chrome
I'm making a windows app for a client using Chrome in kiosk mode. They'd like to burn the project to CD. While this works fine with chrome portable on a read access device it doesn't with a read only device. A warning pops up asking to temporarily copy it to the local drive to run from there. Clicking yes allows the program to work but i'd like to suppress this as they won't want to see it every time. Is there a way for me suppress the warning or cache to the cd before it's burned?
I need to use chrome, not another portable browser. I could be being naive and they're may be a better option than using Portable apps chrome download.
I asked the same question on the Portable apps website and got this response. It worked great although take note of the distribution license.
Add a text file called GoogleChromePortable.ini in your GoogleChromePortable folder that says
[GoogleChromePortable]
RunLocally=true
this will make it copy the profile to the temp folder on the computer and run from there whether it's in read only place or not.
also notice Johns reminder in Pyromaniac's thread (http://portableapps.com/node/37168#comment-207403) - giving someone, especially a "customer" a copy of Google Chrome, Portable or otherwise, is illegal, don't do it.

I've investigated the license agreement and found this
21.2 Subject to the Terms, and in addition to the license grant in Section 9, Google grants you a non-exclusive, non-transferable license to reproduce, distribute, install, and use Google Chrome solely on machines intended for use by your employees, officers, representatives, and agents in connection with your business entity, and provided that their use of Google Chrome will be subject to the Terms.
So legal as long as it's kept internal. Works great if anyone ever stumbles on this question. Chrome makes an awesome portabl app.
To get around user policies you can try a pretty software does what you want.

This uses chrome engine and creates kiosk like portable engine for your given URL or local files. It makes pages looking like windows application. Hope helps.
Note: I'm not the author :)
Here's a link to where I got something that worked for me.
In the Support section, there is a performance note that advices copying GoogleChromePortable.ini from the GoogleChromePortable\Other\Source directory to the GoogleChromePortable directory and editing it to set RunLocally=true in order to increase performance, well this sorts out the warning that pops up.
However take note of the privacy implications of doing this as also stated in the same section.
Hope this helps someone.
You could try Chromium (portable) which also includes chromedriver from chromium snapshots page. Pick one with the biggest number (scroll down):

Fiddler lets me intercept http requests and respond with files from from my local machine. I am looking for a tool that does exactly that, on mac.
I tested charles but its "rewrite tool" does not allow that. I tried also httpscoop which allows only looking at requests, and wireshark where I could not even find the gui (probably due to my noobness on mac)
As far as I understand it, Charles' Map feature offers what you're looking for.
If you have a Windows PC or VM on your Mac, you can use Fiddler to capture the Mac's traffic. Also worth noting is that I'm at Telerik now and one of our goals is to support more platforms with Fiddler. An alpha version of Fiddler for the Mono framework is now available.
you can try a free chrome extension: Trumpet
Features:
Wildcard pattern
RegEx pattern
Category
File drag
Try Tamper, it's based on mitmproxy and it allows you to see all requests made by the current tab, modify them and serve the modified version next time you refresh.
How can I use IE8 Developer Tools to inspect network traffic?
Specifics:
I need to test if files have loaded or if they have loaded slow. In Firefox/Firebug I can do this by using the NET tab.
Restrictions:
I cannot install additional software, so answers in Examine http response headers in IE8 are of no use to me. :( I am debugging issues on restricted computer systems and do not have admin rights.
Rumors?
I have read that there is no way, at all, to inspect network traffic using IE8 Developer Tools, is this true?
Thanks.
In http://blogs.msdn.com/b/ie/archive/2010/04/22/ie9-developer-tools-network-tab.aspx it says:
The developer tools include some new capabilities and improvements
over the tools in IE8:
A new tab for inspecting network traffic.
So this is impossible in IE8 (without installing additional software, that is).
That's that.
