yahoo requests a text code to open my email every time i try to log in on this computer. (it only happens on Mozilla) I don't have a problem with Explorer. (it's a security thing from Yahoo to protect me from someone else getting in from someplace else.)

Chosen solution

This issue can be caused by corrupted cookies or cookies that are blocked.

  • Create a cookie 'allow' exception to keep such cookies, especially in case of secure websites and when cookies expire when Firefox is closed.
  • Tools > Options > Privacy > "Use custom settings for history" > Cookies: Exceptions

This can also be stored in local (DOM) storage or in a Flash cookie.

In case you are using "Clear history when Firefox closes":

  • do not clear the Cookies
  • do not clear the Site Preferences

Clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, passwords, and other website specific data.


Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window
