If you are using older version of Firefox, I will strongly recommend you to install an updated version. It is more secured and also it is much better. If you are using Firefox 11.0.2, it's a very older version. The most recent version can be found here: Firefox.com

Sorry

Then please check this article, it covers the reason you are seeing that: https://support.mozilla.org/en-US/kb/secure-connection-failed-error-message Also at the bottom of the article shows how to bypass the message, if you truly believe the sote is safe. Cause mostly an invalid certificate can be an indication of a web page that will defraud you or steal your identity.

That was the first thing I tried - No dice.

I went to the firefox page - and hit the button 'refresh' There was no warning prior - only after I hit it did it say it would remove all my addons and preferences. Now i'm in it deep - now almost no website works - Not even this one - I had to go to Chrome to use this very website - and I can't access Onedrive. So now the browser is completely useless and I still can't do my university research.

In fact - I am getting the message - connection is not secure on almost every website now. even Adobe Flash page - prior to the firefox 'refresh' it only occurred on the one page.

  • Firstly if you have already refreshed Firefox, you can roll back to your previous settings. Those old stuff will be in a nwe folder on your desktop.
  • Now for your problem, are you using any proxy on Firefox? You can check it by typing or pasting about:preferences on your address bar. Then go to Advance>Network and click on the settings. Check if you have Manual proxy connection. If you are using manual proxy then you may have some problem with that.
  • If there is no manual proxy, then type about:config.
    • You may get a warning, just press I'll be careful.
    • You'll find a search bar at the top. Type and search for security.ssl.enable_ocsp_stapling
    • Right click and choose Toggle

I hope you'll find your solution.

well, I panicked and did an uninstall and then installed the browser. I see the folder you mention = but no way to use the stuff.... It is just a bunch of folders....

But I also followed your other instructions - So effect whatsoever- Should it say 'true' or 'false' ?

almost websites can be opened or display correctly -

The default value will be True. You have to make it False. It is a bypass process. And check this article for recovering old profile: https://support.mozilla.org/en-US/kb/recovering-important-data-from-an-old-profile

Thanks for trying to help -

No Dice.

The browser doesn't work now. I can't even open this page there - it is in the format of blue links and words - not normal website and can't open most other sites at all.

NO idea what to do.

Can you attach a screenshot?

  • 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

Did you check the connection settings in the new profile?


You can check the log in the Web Console for error messages and the Network Monitor (Firefox/Tools > Web Developer) to see if content fails to load or is possibly blocked.

Use Ctrl+F5 or Ctrl+Shift+R to reload the page and bypass the cache to generate a fresh log.


If you can't inspect the certificate via Advanced (I Understand the Risks) then try this:

Open the "Add Security Exception" window by pasting this chrome URL in the Firefox location/address bar and check the certificate:

  • chrome://pippki/content/exceptionDialog.xul

In the location field of this window type or paste the URL of the website with the https:// protocol prefix (https://xxx.xxx).

  • retrieve the certificate via the "Get certificate" button
  • click the "View..." button to inspect the certificate in the Certificate Viewer

You can inspect details like the issuer and the certificate chain in the Details tab of the Certificate Viewer. Check who is the issuer of the certificate. If necessary then please attach a screenshot that shows the Certificate Viewer.

This is a time to be calm. Do you still have the Old Firefox Data folder on your desktop from the Refresh? Please keep that in case we need to restore things from it. Don't use the Windows "system restore" feature since that has been known to remove that folder.

Originally, you were getting the code "ssl_error_bad_mac_read" which is fairly unusual. But now you probably are getting a different code, maybe the much more common "sec_error_unknown_issuer". Could you check some error pages, click the Advanced button, and let us know what code(s) you're getting?

For future reference if relevant: How to troubleshoot security error codes on secure websites.

You can use the contents of the Old Firefox Data folder to "roll back" the Refresh, but it does involve several steps. This takes 5 minutes, but that may be faster than recovering individual files and loading those into your new profile manually.

Check inside the "Old Firefox Data" folder that Refresh adds to your desktop for a folder with a semi-randomized name. If there's only one, that probably has your old settings and add-ons. If there's more than one, you'll want to work with the one that was updated most recently.

Once you have identified the profile folder you want to restore, here is my suggested "old profile resurrection procedure":

Overview

These are the steps described in more detail below:

  1. Create a new Firefox profile
  2. Remove everything from that new profile folder
  3. Copy in everything from the old profile folder

Create a new Firefox profile (Windows)

Exit Firefox completely, and then start up in the Profile Manager by pasting the following into the Windows search box, or the Run dialog, and pressing Enter:

firefox.exe -P

Note: Any time you want to switch profiles, exit Firefox and return to this dialog.

Click the Create Profile button, assign a name like OldSettings, and skip the option to change the folder location. Then select that new profile in the dialog and start Firefox.

Open the New Profile folder in Windows Explorer

Firefox in the new profile should look like a factory fresh installation. Open the Troubleshooting Information page using either:

  • "3-bar" menu button > "?" button > Troubleshooting Information
  • Help menu > Troubleshooting Information
  • type or paste about:support in the address bar and press Enter

In the first table, click the "Show Folder" button. Firefox will launch your brand new profile folder in Windows Explorer.

Leaving that folder open, switch back to Firefox, and Exit using either:

  • "3-bar" menu button > "power" button
  • (menu bar) File > Exit

When Firefox closes, the profile folder should be front and center, or you can activate it using the Task bar.

Copy Old Data in Place of New

In that new profile folder you just popped open -- NOT the one on your desktop -- select all the contents (you can use Ctrl+a) and delete (you can press the Delete key on the keyboard).

Leaving that window open, open or switch over to your Old Firefox Data folder. Drill down into your old profile folder. At this level you should see a folder named bookmarkbackups among other things.

Select everything (Ctrl+a) and Copy (either right-click > Copy or Ctrl+c).

Switch to the empty new profile folder in other window and Paste (either right-click > Paste or Ctrl+v). This may take a minute since some of the files are large.

Start Firefox

Firefox should start up in that "new" profile with the resurrected old profile data. Success?
