Hello,

According to the add-on page (https://addons.mozilla.org/en-US/firefox/addon/firefox-os-simulator/ ), you can go to Web Developer > Firefox OS Simulator to access its features.

• It might also be in: > Developer

I have both FIrefox OS 1.1 Simulator and Firefox Os 2.2 Simulator,I can only access Firefox Os 1.1 from there,also see this http://prntscr.com/4ycvxu

Hello,

Based on the description here:

• https://developer.mozilla.org/en-US/Firefox_OS/Using_the_App_Manager

It seems like Firefox OS 2.2 uses the about:app-manager page.

Sorry, I am not familiar with these tools, if you are still having problems please post here again and someone more familiar with them can help you.

Sorry bro,doesnt seem to work.

try pressing ctrl+shift+A keys to see the Add Ons.

This is where you can get the 2.2 simulator, keeping in mind that it is UNSTABLE. https://ftp.mozilla.org/pub/mozilla.org/labs/fxos-simulator/

Hello Bluey656,

Your user agent shows you are using Firefox 32, you might need to upgrade to version 33 to use the about:app-manager page. At the bottom of the page should have a Start Simulator button.

If you have already done all that, can you maybe post a screenshot, or give a little more description of what happens?

If you need help to create a screenshot, please see How do I create a screenshot of my problem?

Once you've done this, attach the saved screenshot file to your forum post by clicking the Browse... button below the Post a reply box. This will help us to visualize the problem.
