I got confused about the secure site not being secure. Either it uses HTTPS addresses -- and therefore the content is encrypted when send/received from/by Firefox -- or it uses HTTP addresses that offer no security against sniffing. I can't see how it could be both at the same time, but maybe I'm just not understanding what's happening.

Are you getting the full page error "Your connection is not secure"? These are the most relevant articles for that error:

• What do the security warning codes mean?
• How to troubleshoot security error codes on secure websites

Or is Firefox is blocking part of the site because it's has "mixed active content"? See this article for more information on how to make an exception, assuming you trust the blocked content: Mixed content blocking in Firefox.

Or is it something else?

According to juno.com, because my webmail passes through and is controlled by their secure https server and cannot be accessed through any other way than by passing through said secure website and is not available any other way than by signing into their secure website, it is secure.

I am having an ever increasing problem seeing my e-mails, to include postings from facebook that goes to my e-mail and even worse, I cannot delete e-mail that is nothing but an add even when I don't want to open the e-mail. On the other hand, I cannot delete an add from Sees.com without first going into the e-mail.

Okay, I'm going to start with these specific issues because I don't understand the security problem:

So first, you get notification emails from Facebook and you cannot see their contents, or cannot see their full contents. Is that correct? Is there any error message or other explanation from Firefox about the problem? Do you notice a pattern of what is missing, for example, photo missing, video missing, etc.?

Second, you want to delete email from your inbox without having to open the message, but you can't do it. How is it supposed to work? For example, click or tap a checkbox and then use a Delete button or Delete menu item? Where is the process breaking down?

If you haven't already, I suggest "the usual":

If a site is generally known to work in Firefox, these are general suggestions to try when it stops working:

Cache and Cookies: 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

See: How to clear the Firefox cache

If you have a large hard drive, this might take a few minutes. If you do not see the number going down on the page, you can reload it using Ctrl+r to check progress.

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

• right-click (on Mac Ctrl+click) a blank area of the page and choose View Page Info > Security > "View Cookies"
• (menu bar) Tools > Page Info > Security > "View Cookies"
• click the padlock or "i" icon in the address bar, then the ">" button, then More Information, and finally the "View Cookies" button

In the dialog that opens, the current site should be pre-filled in the search box at the top of the dialog so you can remove that site's cookies individually.

Then try reloading the page. Does that help?

Testing in Firefox's Safe Mode: In Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, and some other advanced features to help you assess whether these are causing the problem.

If Firefox is not running: Hold down the Shift key when starting Firefox.

If Firefox is running: You can restart Firefox in Safe Mode using either:

• "3-bar" menu button > "?" button > Restart with Add-ons Disabled
• Help menu > Restart with Add-ons Disabled

and OK the restart.

Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).
