It's great to be able to watch your favorite videos and other Flash content on a mobile phone, but it can affect the overall performance and interactivity of the browser, as well as network and battery consumption. We're working on an add-on that will give you complete control by letting you enable plugins, like Flash, for only the sites you choose. In the meantime, we've built an add-on that enables video on YouTube, a site that serves content well-optimized for mobile, and is, well, pretty popular. Here's how you get it installed - enjoy!
Step 1: Swipe over to the right sidebar and select Browser Tools (the gear button).
Step 2: Switch to the Add-ons Manager (the puzzle piece), and pan down to the Get Add-ons section
Step 3: Tap on the recommended add-on "YouTube Enabler", press "Add to Firefox" button, and restart Firefox when prompted. (If you don't see it there, just type "YouTube" into the Search Catalog field).
Step 4: Go to YouTube.com and play Flash videos!
But wait, there's more!
You can make your YouTube experience even better by adding a YouTube search button to Firefox.
Step 1: Go to youtube.com, tap on Firefox's site button, and tap the "Add Search" button.
Step 2: From now on, search for your favorite videos on YouTube directly from Firefox! Enter what you're looking for and tap the YouTube Video Search button.
