Hello,

I guess this is sudden, so did you install any 3rd party plugins/software on your computer ? Download managers which scan for links, and antivirus/firewall monitoring your connection could be the reason you can't access to these specific pages.

Have a nice day,

No new software or anything....last week FireFox starting saying gmail login pages were not authentic, then when I went to click on exception it worked sometimes...then that stopping working, and I'd have to shut the computer down and after restarting it would allow me to login in to https sites....then tonight nothing works.....btw I'm a complete computer novice...just an fyi

Hello 'gain,

are you using some shared internet connection ? There may be an administrator behind it restricting on purpose access to some websites.

If not, I would advise downloading some antivirus and scanning your computer with it.

Did you notice any kind of slow-down, unwanted alerts within windows itself ?

Let me know,
