Firefox is my default browser, and Google.co.uk is my home page - every time I startup Firefox the url redirects to https://www.google.co.uk/?gws_rd=ssl and I get the SEC_ERROR_BAD_SIGNATURE problem. The message seems to happen on other https:// urls within Firefox but the same pages are easily accessed when using Chrome browser. I am using Bullguard internet security. Thanks in advance. Dave S
