Make Mobile Firefox Always Runs in Desktop Mode

If you are using Firefox browser on your Android device, you will notice that there is a setting where you can check to “Request Desktop Site”. By default, mobile Firefox comes with a mobile user agent and most websites tend to serve a mobile site upon detecting this user agent, regardless you are using your mobile phone or a 10-inch tablet. When browsing on a tablet, you will have a better experience browsing with the desktop mode than the mobile version of the site. There are two ways that you can get mobile Firefox to run “Desktop mode” by default.

Desktop by Default is a small addon for the mobile Firefox (works only on Android) that checks the “Request Desktop Site” option whenever a new tab is opened. This will ensure that all the websites are rendered in desktop mode.

If you are not a fan of addon, another way is to set a string to override the user agent of mobile Firefox. One thing to note is that it will render the “Request Desktop Site” option useless.

1. Open a new tab in mobile Firefox and type in the address bar “about:config“.

2. Click the “Add a New Setting” link. Select “String” when it shows a popup.

3. Enter the string “general.useragent.override” for the name.

4. Next, go to UserAgentString and search for the desktop user agent that you want to use. In this case, I will use “Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:25.0) Gecko/20100101 Firefox/25.0“. Enter it as the value for the new “about:config” field created above. Click Ok.

That’s it. Restart your Firefox browser and it should render websites in desktop mode now.

  1. Great article, and very handy tweak.

    Is this your only article on Firefox for Android? Or do you have more articles covering Firefox for Android?

    If not, I’d love to see and read more articles Firefox mobile for Android, as well as a tag for it and for future articles.

    • We don’t cover Firefox for Android much, but we will surely do so if there
      is demand for it. There is a split market for the Android browser, so it is
      very hard for us to focus on all of them.

  2. Is there any download manager for Fire fox for Andriod? If any one know please leave a reply.
