That CAPTCHA is generated via an asp link: https://secure.coca-cola.com.sg/img/captcha.asp

See Fix problems that cause images to not show

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

  • Don't make any changes on the Safe mode start window.

See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

You can also try to "Reset all user preferences to Firefox defaults" on the Safe mode start window.

Hi cor-el, thanks cor-el I tried to follow your steps, but until now it doesnt work. Maybe I should have a look into the add-ons although I think there should be some standard add-ons that should always be in the package coming with FF.

BTW: I reverted back to ver. 3.5.3 because I could not get my hindic character sets going and changes in about:config in higher FF versions, I tried until ver. 3.5.12, didnt have any effect. I could probably have deleted all entries there without doing anything.
