Web Visum

This service is often used by blind people who unfortunately are suffering the most from all the captchas being use on websites.

1. You have to start FireFox.

2. Make sure you allow unsigned addons to be installed by following the next steps:

  • In the address bar, type about:config and press Enter/Return. The about:config “This might void your warranty!” warning page may appear. Click I'll be careful, I promise!I accept the risk! to continue to the about:config page.
  • set “xpinstall.signatures.required” to “false”

3. install an AddOn from there Website (direct link to addon).

You should create an account there as well to redirect the unsolved captchas and other queries to that service as well.

Once enabled and you surf with FireFox, you will be able to see the captchas in Captcha Breaker trying to solve it.

Captcha Breaker

Set it up as on the screenshot below:

In short all you have to do is checking the service to simulate Web Visum.
