In case you haven't already... 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) Bypass Firefox's Cache

Use Ctrl+Shift+r to reload the page fresh from the server.

Alternately, you also can clear Firefox's cache completely using:

orange Firefox button (or Tools menu) > Options > Advanced

On the Network mini-tab > Cached Web Content : "Clear Now"

If you have a large hard drive, this might take a few minutes.

(2) Remove the site's cookies (save any pending work first). While viewing a page on the site, try either:

• right-click and choose View Page Info > Security > "View Cookies"
• Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"

In the dialog that opens, you can remove the site's cookies individually.

Then try reloading the page. Does that help?

And of course, you know I have to say... Firefox 18 is not secure; Mozilla discloses security flaws after each new release. Is something holding you back from upgrading to Firefox 28? Please let us know so we can suggest solutions or workarounds.

Also, if you were recently upgraded to a newer version of Yahoo mail...

After removing your Yahoo cookies, do not use an old URL to load your mail, instead, go to one of these Yahoo pages and click on login or mail from there:

• Yahoo home page: https://www.yahoo.com/
• My Yahoo page: https://my.yahoo.com/
• General mail redirect: https://mail.yahoo.com/
• AT&T users: http://att.yahoo.com/
• Other country sites (not on .com): the main Yahoo page for your country

Then you can update your bookmark/home page to the new mail address as needed.

Thanks jscher2000, installing the latest version of Firefox completely solved the problem.

Thanks,
