You Might have come across this issue on the web, usually when you click on a mailto link Firefox would try to launch the default email client on your machine, usually Outlook for Windows users, if you have configured Outlook then it’s ok but most users don’t use desktop email clients like Outlook or Thunderbird , It would be great if it opened Gmail Instead.
This can be achieved by two ways,
1.The first one involves Installing the Google Toolbar for Firefox which provides an option to make Gmail the default email client.
The Google Toolbar also adds some pretty useful features to your browser like the ability to access your Google Bookmarks, check the Importance of a particular website in Google’s view with the PageRank Info, highlighting your search terms on a webpage and auto completion of search terms in the search bar.
2. The Second option is to add Gmail as the default application in Firefox which handles mailto links.
Here’s a Visual walk through on how to make Gmail the default email client for your Firefox browser
Get Google Toolbar for Firefox and Install it and restart your browser, you should now see Google Toolbar on your browser Go to the Settings option on the toolbar and click on Options
