Header Tool

You can easily modify header on each HTTP call on the Mozilla Firefox. The tool is based on the same mainstream idea of modifying the header but uses a more simple text editor interface to more quickly edit, store and save for multiple and repeated test cases.

Using this tool you can easily modify the header on each HTTP call on the Mozilla Firefox. The tool is based on the same mainstream idea of modifying the header but uses a more simple text editor interface to more quickly edit, store and save for multiple and repeated test cases. For example, you can save your header in a simple txt file and reuse it by just copying crtl+C and pasting crtl+V it to the Mozilla Firefox Header Tool sidebar (F10→Menu→View→Side Bar→Header Tool). If you find an issue or you have an idea on how to improve this plugin pleaseopen a ticket, as soon as possible i'll try to fix it. If you are a developer don't hesitate to send to me the patch

Strengths : simplicity, JS substitution like base 64, quick changes can be done easy. to Support for JS substitution in ${ } statement that permits you to do, for example :

#========================================================================================
X-USERNAME    : ${b64('foo')}                      #base64 encoding"
X-NOW         : ${new Date()}                      #current date"
#========================================================================================
Authorization : Basic ${b64("username:password")}  #implement Base authentication easily
#========================================================================================
X-SUMS     : ${
                  var a = "";                      #or do complex things :P
                  for(i = 0; i<100;++i){
                       a+=i
                  }
                a;
              }
#========================================================================================

Javascript can be refreshed dynamically for each HTTP request selecting the continuous checkbox (since version 0.6.0).

#========================================================================================
x-multiline-js: ${
//split header def on multiple line
"aaaaaaa"
}
#========================================================================================
X-PATH   : ${
        encodeURIComponent(
          ""+getPathname()+getSearch()
      ) }
#========================================================================================
#this is a comment
x-header-example  : thisIsThe.Value           #this is an inline comment
x-header-example2 : an other text with spaces #this is an inline comment
x-header-example3 : text with %&£ $imbol$     #this is an inline comment
#========================================================================================

Crypto functionalities

X-MD5    : ${md5('message')}
X-SHA1   : ${sha1('message')}
X-SHA256 : ${sha256('message')}

Example

Accept-Charset:            # Remove this header
Accept-Language:fr         # Change to "fr" for every request
@.*gif                     # Work on any http://*.gif
Accept:*/*                 # Change Accept request to */*

You can also use the internal function crypto("sha1","plain text"); where the first argument can vary between:

• 'md2'
• 'md5'
• 'sha1'
• 'sha256'
• 'sha384'
• 'sha512'

Regular Expression Support

You can use the "@" character at the first char in a line in order to specify a regular expression set of header. Since this line all the headers above are activated only for the matching URI.

#========================================================================================
x-all-0 : header-value      //no @modification so is always enabled
@serverURI_1
x-all-1a : header-value     //is taken in account only for server with serverURI_1 
x-all-1b : header-value     //is taken in account only for server with serverURI_1 
@serverURI_2
x-all-2 : header-value      //is taken in account only for server with serverURI_2

x-all-0 : header-value      //no @modification so is always enabled
x-all-1 : header-value
@^https                     //the following two headers is enabled only for HTTPS
x-all-1a : header-value     
x-all-1b : header-value     
@prod                       //the following headers are enabled only for URI with "prod" inside
x-all-2 : header-value      
#========================================================================================

Move from Modify Headers

If you are already using modify headers you can simply switch to this plugin just with the following steps :

• enable all the headers inside the modify headers Enable All Button
• open a site for header visualization http://headers.online
