” … If you have upgraded your Firefox browser to Firefox 21, the version that got released yesterday, you may have noticed that plugins or extensions that were formerly usable in the browser were not anymore after the upgrade.

Unfortunately, North Americans looking to purchase a local smartphone packed with Mozilla’s new Firefox OS won’t see them on the market until 2014. Why? Because unlike the rest of the world, Silicon Valley sees everything through high-end devices, he said.

I ended up aborting the install and then going over to the FTP server and download the full version of the Beta installer (in this case Firefox 21 Beta 2). The stub installer is also on the Auora and Nightly channels as well. Again, if you want the full version of the installer, you should be able to find it on the Mozilla FTP sever.

• In a new tab type about:config and press enter
• If you get a warning about “Voiding you warranty”, click the I’ll be careful, I promise button
• In the filter field type: browser.download.useToolkitUI
• Double-click the entry to change the value to true

Now, you are back to the old movable window. However, there is talk that once Australias (user interface) is finally fully implemented the old Toolkit UI based downloads window may be going away.

There is another option, which I prefer to use: Download Manager Tweak add-on. This add-on will also restore the old window based download manager, plus for those who prefer to have their downloads in a tab or in the sidebar this add-on gives you that option. There are many more options as seen in the screenshots below:

The Download Manager Tweak add-on works with Firefox 3.0 to the present release version. There has been some feedback that the add-on is not working correctly in Firefox 21 Beta at press time.

Gary joined us to make a dramatic pivot — to move Mozilla from the desktop browser world into the mobile ecosystem. In 2010 we knew that we would need to change many things in order to be effective in the mobile computing environment: our technology, our expertise, our worldview, our focus. Gary’s leadership during this period has helped us build on the strong foundation to make these changes, and to bring that strength into the mobile environment. Gary has reinvigorated our focus on working with commercial partners, a trait that was central in Mozilla’s early life but less so during the Firefox desktop era.
