Mozilla has released Firefox 34 with the new search UI, Yahoo search as default in North America, and WebRTC feature with the name Firefox Hello. Haven’t found the Hello button in the additional tools and Features drawer to drag and drop onto the toolbar to use even though you’ve performed clean install of Firefox 34-  restoring defaults in the Customize window doesn’t help -you’re not the only one, most users haven’t got this button.

Reason: Mozilla has intentionally not enabled the button for users, they’re not confident of their servers taking the load when users use this feature, that’s why they’ve set the throttling to 10%.

FirefoxHello button in version 34

“Right now (December 1st), the throttle is set to 10%. Your browser has only a one-in-ten chance of having the Hello button show up. We will increase this number as we become confident that the servers can take the load’, Mozilla’s Adam Roach  said in a bug.

But with a hack you can get it, here is how.

How to Enable/get the Hello button in Firefox 34 customize window?

1. Visit about:config

2. Change  loop.throttled preference value to ‘false’.

3. Restart the browser, Hello button now appears when you open the Customizing mode, drag and drop it onto the menu or toolbar and start making video calls with your friends.

Note: If you don’t really use that feature, there is really no meaning in enabling the hack, so remain it as it is. Use it when Mozilla makes it available to all.

Are you affected? Can you able to restore the button with the help of this post? Do you actually use Firefox Hello? Let us know in the comments.
