The "old Firefox" folder on your desktop means that Firefox was refreshed. The profile in use at that time was moved to the desktop folder. Some things, history, bookmarks, passwords, were copied to the newly created user folder. But not things like settings, add-ons and others.

What is the current name of the profile folder?

When you reset Firefox then a new default profile is created and a time stamp in Unix epoch format is appended, so it is possible to find out when the profile has been created.

You can use this button to go to the current Firefox profile folder:

• Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
• http://kb.mozillazine.org/Profile_folder_-_Firefox

What icons do you see that images are insecure? If there is mixed passive content (e.g. images) then Firefox shows a padlock with an exclamation mark instead of the normal padlock on the location/address bar.

Corel: I hope that I did this correctly.

First of all, I must note that the ONLY website I see these warning icons is my E-MAIL. I have not seen these warnings on any other websites. The website itself does not have a warning, only individual e-mails. ALSO, the warning icon remains when you go to another message (even though it is a "safe" message). This icon remains until you do a "reload the current page".

Here is the name of the folder I found when I tried to follow the directions):

1mmn2n7g.default-1422052873522

      ***********************************************************

I see these warning icons on some of the e-mails. This only started after I installed Version 42.0. I NEVER had them previously.

I get the Green Lock with grey triangle.

I get the grey lock with the ORANGE triangle (the most prevalent warnings).

  *********************************************************

I have NEVER refreshed Firefox, however there is this file on the desk top which, as I indicated, shows the name as "Old Firefox Data".

*********************************************************

I did contact the e-mail support, and they were unable to help.

Thank you for any advice you may be able to provide which will help me out of this dilemma.

FredMcD: Thank you for your comments. I have never refreshed Firefox, which is one reason I am so baffled by the problems I'm having. I do appreciate any and all suggestions.

That profile was created at the beginning of this year: 1422052873522: Fri Jan 23, 2015 So it isn't recent. I assume that the time stamps of the files in the "Old Firefox Data" folder on the desktop confirm this.

Can you attach a screenshot that shows these warning icons?

• http://en.wikipedia.org/wiki/Screenshot
• https://support.mozilla.org/kb/how-do-i-create-screenshot-my-problem

• Use a compressed image type like PNG or JPG to save the screenshot
• Make sure that you do not exceed the maximum size of 1 MB

cor-el, I will try to attach a screen shot of the e-mail page. This one has never come up previously with an icon. I cannot send a screen shot of a message because it shows my e-mail address. Do you have a secure address where I could send that?

Pasting the screen shot into the message. Thank you so much for your help, cor-el. I will be away for part of the morning, but back later.

cor-el: My apology for overlooking the reference to the "Old Firefox Data" folder on the desktop.

"Yes", it does reflect that it was created :  ‎January ‎23, ‎2015.

Thank you once again for your help.

I see that as well on the Yahoo log in page. I'll attach a screenshot of the Web Console that shows the blocked mixed content that is some banner that comes via an open http connection.

• https://developer.mozilla.org/Tools/Web_Console

Blocked loading mixed active content "http://ads.yahoo.com/get-user-id?ver=2&n=23351&ts=1447525521&sig=059bb7059de64dee"[Learn More]

cor-el: What does this indicate, and is this a method I could utilize to correct the problem? I apologize for being so dense.  :(

I use a program called mozbackup it saves my profile and restores if I need it to

You can't do anything about this apart from actively blocking this content via an extension like Adblock Plus. The website needs to fix this on their end. Firefox can block such insecure content, so it won't be downloaded to your computer, but you will see the special mixed content padlock on the location bar.

You can contact Yahoo and ask them to ensure that secure https pages do not contain any (commercial) content coming via an insecure open http connection.

cor-el, I contacted Yahoo several times (various agents), and none of them could help. Do I have the option to uninstall Firefox, and then reinstall it again to try to resolve the problem? Also if I have a backup of my bookmarks for FF, can these be imported to the new install? It does not appear that I have any viable options to resolve the problem. Some of the messages with the warnings only have images and short text, NO commercial ads.

Thank you once again for your most valued advice.

Yahoo serves the content of the page that way and allow advertisers to include content coming via an open connection on a secure HTTPS page. Uninstalling and reinstalling Firefox or creating a new profile won't help.

Maybe point Yahoo to articles like these:

• https://developer.mozilla.org/en-US/docs/Security/MixedContent/How_to_fix_website_with_mixed_content
• https://developer.mozilla.org/en-US/docs/Security/MixedContent

• https://support.mozilla.org/kb/how-does-content-isnt-secure-affect-my-safety

This is very disappointing news, cor-el. The most frustrating part of this, is that I changed NOTHING in FF. When the Internet Explorer is used it does not show any warnings about the e-mails. It is only the e-mails that are showing the warnings in Firefox. I have seen nothing when performing ordinary browsing.

Thank you once again for sharing your vast wealth of knowledge to help with this problem.  :)

Did you check on the email page with the Web Console (Firefox menu button or Tools > Web Developer) what content is causing this warning to appear?

Firefox only blocks mixed active content like ads in an iframe, but for embedded images only shows a warning and doesn't block images. If only content for advertisements are blocked then I shouldn't worry. If images embedded in an email are blocked then this is more likely a safety feature of the email service and there is usually a button to unlock such blocked images.

cor-el, I copied what the web console shows, and here is what it says:

"This site makes use of a SHA-1 Certificate; it's recommended you use certificates with signature algorithms that use hash functions stronger than SHA-1.[Learn More] support.cdn.mozilla.net DARLA notice: 400 combo:3:16140

This message has no images at all on it. It only has a short text, and a link to Fox news. video. Can you please interpret what this means for me? I do not understand what it means?

Thank you so much for your help. I am very grateful, cor-el

cor-el: I went back to the message, and here is what the information says now:

Loading mixed (insecure) display content "http://mandrillapp.com/track/open.php?u=30011389&id=28ceac92c2ed4436864e50ec9ad81f75" on a secure page[Learn More] combo:214:0 DARLA notice: 400

Wonder why there is a difference in the messages. I appreciate your help more than words can say..... I am totally "lost".  :(

cor-el: I think I asked this previously. Would the Firefox "refresh" action be able to correct this?

In the e-mail, when a message shows the orange warning, even when I go back to the "in box", the icon still remains on the next message even though it is "secure". It does not disappear until I reload the page, and then it reflects that this message is secure. Strange that it would do that.

Hi Boudica I wrote above in one of my replies: Uninstalling and reinstalling Firefox or creating a new profile won't help.

I didn't explicitly mention a reset/refresh, but a refresh creates a new profile and tries to transfer some data to the new profile.

This is really a Yahoo problem and you could only solve this by blocking involved content via a content blocking extension like Adblock Plus of uBlock. But I don't know what content this is about and I'm not using either extension myself.

cor-el: I finally bit the bullet and installed a second browser. The problems I encountered are exactly the same as those I am experiencing in Firefox.

Thank you for reiterating information about uninstalling/reinstalling, and also referencing the reset/refresh information. I don't know if the Adblock Plus will be effective because there is NOTHING in these messages which could cause a problem. There are a very, very few which have "ad images" on them, and some which have only a "URL" (e.g. Fox News), that are showing the insecure icons.

cor-el, you are exactly CORRECT. This is definitely a YAHOO PROBLEM. I went back to the oldest message I had sent to them when I received an error message. This was prior to the time I noted the "icon warnings, so I may have to try the Adblock, or something else the Firefox may have which could possibly help.

Once again, cor-el, I do thank you very, very much for all of your most valued advice. I don't know what I would have done without your outstanding assistance!! I appreciate your help more than words can adequately express!  :)
