Firefox does not trust any connections/security certificates

I've just updated to the latest version of firefox and now whenever I visit a secure website, I tells me that it is an unreliable connection and need to add an exception to visit. When you view the certificate shows he cannot be verified for reasons unknown.

What is happening with all Web sites, including sites such as Google or Facebook.

I've tried a few things I found on the web, but the positions were quite old and does not solve the problem so would appreciate any help I can get

Also, it seems that the ESET AV is intercept the secure traffic. If ESET has an option to install the certificate root in Firefox, you can try that. You can also temporarily check trying to disable HTTPS scanning in ESET. The ESET support would also be useful.

  • Satellite T130 - 10G: Firefox does not read any video or flash content more

    My Firefox does not read any video or flash content more. And in watching the news of repair troubleshooting/malfunction in Firefox under graphics, he said that "Direct2D activated" and 'WebGL Renderer' have been blocked because of the version of the graphics driver.

    I downloaded a new version on the Toshiba site, but an update of the driver can not find the new version.
    I had briefly solved the problem by installing the new driver from the file but it is not recognized in Device Manager.

    Automatic update through Windows just tells me that the driver is up-to-date.
    I have the Satellite T130 - 10G.

    Would be great if someone could help.

    Thank you!

    Hmmmm... as you know Toshiba doesn't support third party software so I think that your question has nothing to do with Toshiba directly.

  • Firefox does not open a new, secure login page, on the site of my Bank

    Site Web of my Bank opens a new, secure, log in page from a link on its home page. When I click on this link to do, nothing happens. No window opens and Firefox does not all messages as to why. He used to work, but stopped in the past two months. I don't know if it something in my settings or not. I also use the Flock browser - which is based on Mozilla code and the link works in this browser. Settings in both browsers seem to be the same.

    URL of affected sites

    http://banksa.com.au

    I get the login window in Firefox.

    It uses javascript to open the window. Try hitting control + F5 - that recharges all of the scripts in case one is corrupt in the cache.

    You have additional modules that may be blocking scripts? Adblock Plus, no Script...
    If so try to disable them.

    When click on Firefox-> Add - ons, the new Add-ons Manager opens in a new tab.

All these excellent work except for the tab 'Extensions', which says that I have no extensions. However, in the lower right of the window, icons for extensions, I was using Firefox 3.6 appear as they did in this version of the browser. All my previous extensions are fully functional.

    You seem to have been using this profile with some testing of Firefox version according to the presence of many extensions.checkCompatibility. * prefs in your list of system details more.

    You may create a new profile as a test to see if your profile is the source of the problems.

    See:

    There may be extensions and plugins installed by default in a new profile, so check that in "tools > Modules > Extensions & Plugins" in case there are still problems.

    If this new profile works then you can transfer files from the old profile to the new profile (be careful not to copy corrupted files)

  • Firefox does not save the connection ID

    I would like to register my code for the sites that require a login. I never save the password, just the code.
    Don't know what combination of setting lets do this
    The parameters I tried:
    Don't forget history of navigation > 0
    And parameters customized to clear:
    Clear passwords
    Clear shape data
    It seems that when I put "remember...". "0 days then my ID disappears the next day. I do check not control it clear of passwords and Date of precise form on the assumption that these two ratingses, but that makes no difference.

    In Firefox 3.5 and later "form and search history" entries expire just like the "regular" browser history

    The pref browser.history_expire_days determines the expiration of items of history and also data form and the research of the effects.

    See http://kb.mozillazine.org/browser.history_expire_days (180) (also affects saved form data)

    Make sure that you do not remove the navigation, search and download history on Firefox to clear "form & search history".

  • Firefox does not recognize the certificates of all permitted https sites. Any ideas how to fix?

    I downloaded firefox, checked for malicious and verified software for viruses. Firefox allows to work in this environment. At some malware - corrected and now does not open any trusted site. Rpet certificate is not good. I checked several site certificates and they are good. Help?

    I guess that you install Fiddler, which is used by web developers...

    The presence of this certificate may indicate malware named backup browser.

    In Control Panel, uninstall a program, I suggest that once the list is loaded, you click on the column heading "installed on" to group infections, I mean additions by date. See if you can find BrowserSafe/browser backup or similar and remove.

  • Firefox does not connect to any site since the new update to download.

    Firefox does not connect to all websites since the installation of the last update. Google Chrome and Internet work.

    Some problems occurs when your Internet security program was set to trust to the
    a previous version of Firefox, but no longer recognizes your updated as version
    level of confidence. Now how do I solve the problem: to allow Firefox to connect to the Internet
    Once again;

    • Make sure your Internet security software is up-to-date (for example, you are using the latest version)
    • Delete Firefox to list your program of trusted or recognized programs, then add it again. For detailed instructions, see

  • Firefox does not connect to any Web site, but other browsers will.

    When I get something in the URL- google.com, localhost, http://127.0.0.1/ one bar the IP address, there is a fraction of a second flash, then the bar becomes empty and nothing has changed. It seems that Firefox is not even try to connect to the internet.

    Yesterday, everything was fine when I was running FF on Windows 7. After the upgrade to Windows Pro 8, Firefox has failed. I've updated for Windows 8.1, hoping for the best, but it's the same problem.

    I've walked by the firewall program, several times (the only race is the built-in Windows Firewall). Finally, I uninstalled Firefox, including all my settings, custom and reinstalled from scratch, twice. And even this version pure and clean Firefox does not connect to the internet.

    I am a computer web developer and would be happy to look at the log files or run a tool (Fiddler?) to see what happens at a low level, if I only knew where to look.

    john99, thanks for the links. I went through all (again), one by one. The last link kb.mozillazine.org/Standard_diagnostic showed me what helped. I've renamed "firefox.exe" to "firefox1.exe" and was able to use firefox.

    It made me suspect the firewall or malicious software. I ran a Malwarebytes full scan, zero problems detected. I have pored on the entries of windows firewall, the "Windows Firewall with advanced security" view and also the simple control panel view. The only mention of Firefox is that I continue to add and remove to allow firefox through.

    Here I knew what was going on, but for now, I can at least use firefox. How frustrating!
