title: custom firefox profile in selenium causes addons to be incompatible
body: <p>Now this is tricky. I am trying to do WAP testing using firefox and selenium. For that I've created a custom profile and installed a plugin called modify headers. When I launch the profile manually, the addon works fine. But, when I use it with Selenium RC, then, Firefox disables the plugin, saying that it is incompatible with Firefox 3.6.6. This is ridiculous.If I open the same firefox profile manually, the plugin works fine. Also, when I update plugin (in the profile launched by ff),I installs a compatibility patch and works fine after restarting FF. But, when I close firefox and launch the same profile from selenium, it again gives the same problem. Please help, a lot of my test cases are based on WAP. You can also suggest alternatives to this plugin.</p>
  
  <p>Thanks and Regards<br/>
