To fix user agent compatibility issues you can run K-Meleon in Firefox Compatability mode. If you are receiving 'upgrade your browser messages' or getting the mobile version of a web page, this is likely the issue. This can create a problem if the web developer only targeted the most common browsers and you are using an uncommon browser like K-Meleon. Depending on the site, this is usually a simple layout for mobile phones or an error page advising you to upgrade your browser. If a web page is designed to check for a user agent, it may include a fallback page. Web developers will sometimes create different versions of a page to be delivered for different user agents. The user agent string includes information about your device. Click it to bring up the selection menu, and choose the one you want.Web browsers identify themselves to web pages with a user agent. Just click the sliders icon in the upper left (settings) and then down a little ways you should find an option called User Agents. Once installed, you don't even need to restart Firefox. It should be the first one that comes up. Now click on the puzzle piece in the top right (plug-ins and extensions), then click the Get Add-ons input field and type in 'phony'. Click on the gear/cog at the bottom right to open up settings. Once downloaded and installed, open Firefox and swipe to the left to bring the right side-bar into view.

Once there, click the search icon (magnifying glass) and search for 'firefox'.

Go into your Applications menu and find Play Shop (used to be called Android Market). The first thing you want to do is download Firefox from the Google Play Shop. I use Firefox with the desktop user agent spoof, which allows me to browse sites as if I were on a desktop PC. The Phony plug-in interfaces directly with Firefox's settings panel, and gives a convenient drop-down list for user agents (so you don't have to know the actual user agent string). This allows you to make websites think you're browsing on a desktop computer, iPhone, or something else. You can spoof the user agent on your Android phone fairly easily, using Firefox and the Phony plug-in.
