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

Tools > Options > Advanced > Network > Offline Storage (Cache): "Clear Now"

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

right-click the page, choose View Page Info > Security > "View Cookies"

Does that help?

Tried everything you suggested, no change, I get the blog but not any access to sign in. Very odd, but it does work fine in IE. Another one of those annoying things, actually I also had problems with Youtube on Firefox, and can only access that from IE also.

frustrating little things.

Can you attach a screenshot?

Use a compressed image type like PNG or JPG to save the screenshot and make sure that you do not exceed the maximum file size (1 MB).

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

• Don't make any changes on the Safe mode start window.
