Hi tony666, Firefox follows the platform convention on how you access the Preferences:

Windows: "3-bar" menu button (or Tools menu) > Options Mac: "3-bar" menu button (or Firefox menu) > Preferences Linux: "3-bar" menu button (or Edit menu) > Preferences

Or you can type or paste about:preferences in the address bar and press Enter/Return to load it.

Google Play said its cookies are blocked. What gives?

Good question. It's possibly a problem with not allowing third party cookies if Google needs to access one of its other domains to sign you in on Google Play. This article has more on cookie settings: Websites say cookies are blocked - Unblock them.

You can inspect cookies and passwords and permissions for the domain in the currently selected tab via these steps:

• click the "Site Identity Button" (Control Center 'i' button) at the left end of the location/address bar
• click the arrow to expand the security message
• click "More Information" to open "Tools -> Page Info"
• click "Permissions" to inspect and modify permissions
• click "Security" to inspect and modify cookies and passwords in a standalone window

• click "View Cookies" in "Tools -> Page Info -> Security" to inspect the cookies from the domain in the currently selected tab
• click "View Saved Passwords" in "Tools -> Page Info -> Security" to inspect the passwords from the domain in the currently selected tab

Clear the cache and remove the cookies from websites that cause problems via the "3-bar" Firefox menu button (Options/Preferences).

"Clear the cache":

• Firefox/Options/Preferences -> Advanced -> Network -> Cached Web Content: "Clear Now"

"Remove the cookies" from websites that cause problems.

• Firefox/Options/Preferences -> Privacy -> "Use custom settings for history" -> Cookies: "Show Cookies"

Thanks for all the info. Very helpful. I found everything.
