While trying to login to this blog a few days ago, I got this error message on my WordPress login page:
“ERROR: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress.”
In case you come across this issue while trying to log in or access a certain website because the cookies are blocked, then just follow these few simple steps to check or change the settings on Mozilla Firefox.
- Open Mozilla Firefox and click on the Menu button, then select Options.
- Select the Privacy tab or section.
- Under History, Look for “Firefox will” and select “Use custom settings for history“.
- To enable cookies, make sure that “Accept cookies from sites” is checked.
- If the “Accept cookies from sites” is checked and you still get the same error message, click on “Exceptions” and make sure that the website that you want to access isn’t listed there. If you find it listed, then just select the particular website and click “Remove“.
- You can also choose how long cookies will be stored:
- Keep until: they expire: Each cookie will be deleted when it reaches its expiration date, (set by the site that sent the cookie).
- Keep until: I close Firefox: Cookies stored on the computer will be removed when the user closes Firefox.
- Keep until: ask me every time: Displays an alert every time a website tries to send a cookie, and asks you whether or not you want to store it.
- When you’re done changing the settings, click OK.
In case you want to do the opposite and would like to disable cookies, then all you need to do is the opposite of the fourth step which is to make sure that the “Accept cookies from sites” is unchecked. Also, if you want to block certain websites, you can add them by clicking on “Exceptions” and manually typing in the URL or web address.
For this article/tutorial, I’m using the latest version – Firefox 36.0.4. In case you’re using an older version of Firefox: Look for the Firefox button (top left corner) then click on Options OR look for the Tools menu, click on it and select Options. The rest of the steps would be pretty much the same as the one I listed above.
Btw if you’ve noticed from the screenshots above, I have some settings configured differently such as “Accept third-party cookies” set to “From visited” and “Keep until” set to “I close Firefox”. I strongly recommend that you keep the default settings which are: “Accept third-party cookies” – “Always” and “Keep until” – “they expire“.
Hope this simple guide helps you in case you encounter any problems with cookies being blocked or figuring out how to enable/disable cookies on Mozilla Firefox.
