If the method in the first post won't work for you you might consider using foxfi, pdanet+, or clockworkmod tether. You will have to pay a few bucks for the app but you won't have to mess with permissions or kill tasks on your f6. On the laptop/desktop side you just need to what Trevor said and use Fiddler with the user agent set to custom and this works for Internet Explorer, Chrome, and maybe other browsers too. I haven't been redirected to the upsell page since I started using this method. (I have never tried clockworkmod tether I've just read that it works for this. I have used both foxfi and pdanet+ for this and they both work great. Just checked the play store and clockworkmod tether is USB only. Foxfi and pdanet+ support WiFi, Bluetooth, and USB tethering.)
