Here's what you do:
- In the address bar, type: about:debug and hit return
- This might look like it hasn't done anything, but head to the
settings menu and you'll find new options there.
- You're looking for a new menu called UAString. Open up UAString
and select Desktop.
- Return to your browser and head back to that pesky page.
That's all there is to it. Your browser will be seen as a
desktop browser when you visit sites.
It isn't foolproof though. Occasionally you'll still run into a
mobile site, but generally speaking they will no longer be a
problem. Some elements of full sites might not work too, so be
warned.
You can turn the UAString (user agent string) back, by simply
opening up the menu again and switching. Leave all the other
settings alone, and if you want to hide those extra options, then
type about:debug again to turn them off.
It's worth noting that if you're lucky enough to have Ice Cream
Sandwich, you don't need to do this, as there is a "view desktop
version" in the settings menu.
If you don't fancy fiddling with settings, you could also try a
different browser, like Dolphin Browser HD, which also comes with the
option in the settings.
