@Yoni: Send a message to the Firebug Working Group or submit a bug for HAR issues.

This is great news, however I found a bug(?) that makes it impossible for me to open firebug exported har in HTTPWatch. Some of the cookies use the “version” attribute, in FireBug they are exported correctly but when trying to open it with HTTPWatch is says there is a problem. According to cookies spec this is a valid attribute… the har “spec” I found did not cover this attribute.
Is there a central group where this kind of mismatches can be reported?

Steve, thanks for mentioning Show Slow – I hope it is useful for the community.

As for HAR, it’d be great if this kind of data can be posted to beacons by different monitoring tools so servers can store and report on this data.

I’ll commit that AOL Pagetest will support HAR files in both the desktop and online versions (online first) and for both export and import (and potentially remotely through JSON URLs). I have most of the work done for exporting the files (just have to add the headers) and it will work with any test, including those run over a year ago.

The Internet Archive does capture HTTP headers. They use the WARC file format.

Not everybody wants to purchase an app just to read HTTP logs. There should be a way to load .har files into Firebug. Opening the file in a text editor and pasting its content into the web-based viewer is a bit convoluted, and it renders the data just like Firebug, so why not use the Firebug pane?

Never heard of HttpWatch until now. Thanks for the info and resources; as a web programmer and avid firebug user I will definitely have to give this a try.

@Rohit: Yes, I should have mentioned Net Panel must be enabled. @Wim: That's the beautiful thing about HAR. I love HttpWatch and do so much performance analysis it's worth the cost. But if you prefer another tool, we can still share our files (eventually). I review a bunch of packet sniffers in the appendix of Even Faster Web Sites: AOL Pagetest, WebPagetest, VRTA, Fiddler, Charles, Wireshark, and IBM Page Detailer. The key is - how many of these will adopt HAR? Honza pointed out that DebugBar has already added HAR support.
