I cannot open websites I use new every day
Since yesterday I an getting an error message on all sites" Did not connect: Potential security issue" www.google.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

First, let's figure out where the problem is With a little detective work, we can narrow down the cause of the problem.
Open a new tab and check to see if you can load another website like google.com or mozilla.org. If you can open another site, skip down to The problem only happens with certain websites. If you can't open another site, continue on to the next step. Launch another browser, like Internet Explorer, and try to open the site you were having problems with. If the site works in another browser, see The problem only happens in Firefox. If the site doesn't work in another browser, check out The problem happens in all web browsers.
