Hi rayemathis, which email site is the problem -- Yahoo, Gmail, Hotmail, etc.? Or Outlook Web App?

Can you think of any changes that might have triggered the problem, e.g., updating Firefox or an add-on, or installing a new add-on?

When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.

1. Clear Firefox's Cache

Firefox > Preferences > Advanced

On the Network mini-tab > Offline Storage : "Clear Now"

2. If needed, delete the site's cookies here

While viewing a page on the site, choose

Tools > Page Info > Security > "View Cookies"

Try deleting the cookies and reloading the page. Does that help?

Edit: Before deleting cookies, make sure you save any work in progress, e.g., save any message you're composing to Drafts, since you probably will have to log in again.

Thank you so much. Clearing the cache and cookies fixed the problem. I appreciate the help.
