Firefox fails to display text in Captcha box
On pages or sites which require the use of a Captcha system to prevent botnet access the captch image is not displayed in firefox.
If i log in using IE or Chrome I can see them perfectly but not in Firefox
Windows xp sp3 and firefox version 26.0

You have some extensions that might be playing a role in this. For example, if the site is using Google's ReCAPTCHA service, perhaps Google Disconnect or Ghostery could be hiding it?
To test without any influence from extensions, you could try Firefox's Safe Mode. That's a standard diagnostic tool to bypass interference by extensions (and some custom settings). More info: Diagnose Firefox issues using Troubleshoot Mode.
You can restart Firefox in Safe Mode using
Help > Restart with Add-ons Disabled
In the dialog, click "Start in Safe Mode" (not Reset)
Any difference?
Note that if you use extensions that can block content that you should always be aware that such extensions can block wanted content as they just use some generic filter rules or block all third-party content.
You may need to add exceptions (whitelist) to allow specific content.
