For some inexplicable reason they detect what browser you are using and then make the decision for you whether it’s going to work or not regardless of if the browser you are using will work.

Fortunately, as I’ve previously posted HERE there is a way to solve the problem and fool natwest into thinking you are using a compatible browser.

The new problem is that mozilla have just reclassified the beta release from firefox 3.1 to firefox 3.5. The previous fix involved deleting the beta string from the user agent in about:config leaving Firefox/3.1 or Firefox/3.5 as the user agent. The new problem is that natwest don’t acknowledge the existence of firefox 3.5.

So for the meantime follow the steps in my previous fix making sure the identifier is Firefox/3.1 as before. Least until Natwest catch up or even better remove the stupid browser detection routine

Basically Natwest (and presumably RBS) online banking has the most atrocious browser detection routine which essentially looks at your browser user agent string and if it doesn’t match the strings it’s been told work with the site it refuses to let you in. Now this is stupid because the vast majority of modern browsers work with Natwest no problems however each time a new (or a beta) version comes out Natwest assume that it wont work with online banking.

So once again it’s time for my little trick to make Natwest think it’s working. This involves the following steps

  • In the location bar type “about:config” and press enter
  • You’ll then get a warning about dragons. As Peter Jones isn’t that scary just ignore it
  • Find the preference “general.useragent.extra.firefox” and delete the b3 bit so it reads “Firefox/3.1″
  • Laugh in the face of Natwest’s stupid browser detection system
  • Log into internet banking
  • Send me all your money (just kidding)

Until today I’ve been using the IE Tab extension to make natwest open in an Internet Explorer tab within firefox however that isn’t ideal as it means having to use internet explorer which is never a good idea.

Fortunately, I’ve now solved the problem and internet banking works fine in firefox 3 beta 5. To solve simply crack open about:config in firefox. Ignore the nice warning about dragons and then find the string general.useragent.extra.firefox. Right click on that string and select modify. Then simply remove the b5 so it reads as Firefox/3.0

Firefox will now identify itself as firefox 3 and not as firefox 3b5 and internet banking will no longer complain!
