Fiddler does not capture web request from Firefox

Question

I am new to Fiddler. On my PC, Fiddler can capture a web request sent from IE, but not Firefox. Are there any settings I should look at?

I include All Processes and Capturing, but it still does NOT commit the request from Firefox.

Answer 1

You can also connect a FiddlerHook to Firefox, which allows you to handle how traffic will be routed through Fiddler

Answer 2

I had the same problem. To do this, I just change the Firefox settings to Use system settings of proxy . I hope this is enough for Fiddler to work properly.

UPDATE

As @Ed Birm explained, you can find it here:

Options > Advanced > Network tab> Settings in the connection> Select Use system proxy settings > OK

Or enter the URL about:preferences#advanced , and then find Network tab> Settings in Connection> and select Use system proxy settings and OK .

Answer 3

You can use Fiddler as HTTP PROXY. Then configure the Firefox network settings to use the proxy server and connection parameters, use the default port Fiddler: 8888.

Take a look at this document.

Answer 4

For the latest versions of Fiddler, manually installing FiddlerHook is no longer required. However, you still need to configure the proxy server and certificate for Fiddler in Firefox. This blog post explains these steps .

Answer 5

I had a similar problem ... read the Teleriks blog Configuring Firefox for Fiddler

For me, the solution was to install FireFox to use "Use system proxy settings"
