Jenkins "You must use POST method to trigger builds" Issue

If you are using jenkins and if you ever see any error like this

"You must use POST method to trigger builds. (From scripts you may instead pass a per-project authentication token, or authenticate with your API token.) "

Then it will solve by two ways

1)- you can refer below link
 https://issues.jenkins-ci.org/browse/JENKINS-19368

but it didn't worked for me then I will choose the second way

I don't know how javascript got disabled in my browser after enabling everything seems ok for me.

To enable javascript in firefox

a)-type about:config
b)-Click on I'll be carefull, I promise
c)-search for javaScript:enable and set value to true

Hope this helps someone,
