I got a pop up telling something is trying to trick Firefox into accepting a false update says to contact you?

It has happened more then a few times Its pops up and says Something is trying to trick FF into accepting a fake update.

This issue can be caused by the presence of leftover files in the Firefox program folder (defaults\pref) like a file firefox.js that overrides the update URL with a wrong link.
Do a clean reinstall and be sure to remove the Firefox program folder to remove the file(s) that cause the problem.

I'm getting an error message from Firefox that says, "Something is trying to trick Firefox into accepting an insecure update. Please contact your network provider and seek help."

I'm getting an error message from Firefox that says, "Something is trying to trick Firefox into accepting an insecure update. Please contact your network provider and seek help." Do you know what is going on here--what this problem could be? (I do have the latest Firefox version already installed. I have previously received Firefox error messages that say "Firefox Update Failed." However, I already had the latest Firefox version installed when I received those error messages.)

Apparently this occurs when Firefox has problems with security certificates. There have been a few questions about this. I will try to get advice about this.
Apparently you are using Internet Explorer 9 (From your system details). Do you have Google Updater plugin installed on Firefox ?
(That been implicated in this sort of problem by one poster, and some users with the problem do have Google Updater, but some do not)

Warning notice popping up (in FF 4.0.1) -- "Something is trying to trick Firefox into accepting an insecure update. Please contact your network provider and seek help." Is this a known issue? A manual check for updates results in 'Firefox is up to date'.

OS is Win Vista

"Something is trying to trick Firefox into accepting an insecure update. Please contact your network provider and seek help."

This message appears in regular intervals. I think it is intended to prevent Man-in-the-middle-attacks that want to foist you a rogue Firefox update.
In my company the "Microsoft Forefront Threat Management Gateway" with HTTPS inspection is used. This HTTPS inspection is done by installing a local (company-controlled) Certification Authority in the browser on the users computer and then performing a de/encryption of the SSL-stream on the proxy server.
But as Firefox not only verifies the certificate of the update server, but also the Issuer of the certificate, the update is rejected because of a possible Man-In-The-Middle-attack. In case of the "Microsoft Forefront TMG" this is an intended MITM-attack ...
Is there any possibility to change the expected certificate chain of the update server in Mozilla Firefox?

To access the preferences:
<br> Type '''about:config''' into the url bar and hit enter. Click on the ''I'll be Careful'' button. Then type '''app.update.certs.1.issuerName''' in the filter or search box. Then double-click the pref or right-click > Modify and fill in the new value. Then close Firefox to save the changes.
To add the other 2 preferences (app.update.certs.3.commonName & app.update.certs.3.issuerName) that are not there by default, right-click on one of the prefs inside the the about:config window. Then choose '''New > String'''. Then fill in your custom values in the boxes that pop up for each preference. Make sure to close Firefox to save the changes.

I think I have the latest Firefox version, but keep getting messages about updating it. 1 says something is preventing Firefox from updating securely; another says something is trying to trick Firefox into accepting an unsecure update. What's going on?

The 1st message goes on to say, "Please make sure that you have the latest version of Firefox from http://www.firefox.com." Assuming 4.0.1 is the latest version, it seems this is a bogus message and I haven't clicked on the link.
The 2nd message goes on to say something like, "if this continues [the attempt to trick Firefox into accepting an unsecure update], contact your network administrator."
I started getting the messages on all 4 of our PC's (2 desktops running Windows 7 Home Premium 64-bit, 1 running XP 32-bit, & a laptop running Vista Home Basic 64-bit) after updating to Firefox 4.0 on them. I manually updated to 4.0.1 on all thinking that would stop the messages, but it hasn't.
I loaded & ran free versions of McAfee Stinger, Malwarebytes Anti-Malware, and Super Anti-Spyware programs on all our PCs; each program found & repaired some infected files on each computer, but the messages continue on all.
Thanks for any help you can give.

I am getting an error which says something tried to trick firefox into updating

I've been getting this error for some time I have switched to manual update from time to time I download Firefox Nightly and install it again. I live in Iran since my government is known for invading its citizen privacy I was worried if it is something related to them or other sources trying to modify my firefox or it is a known issue. what should I do? continue my manual download install routine or there is a fix?

Which Firefox version do you use?
Such an error has been mentioned in the past as being caused by the presence of leftover files in the Firefox program folder.
*(32 bit Windows) C:\Program Files\Mozilla Firefox\
*(64 bit Windows) C:\Program Files (x86)\Mozilla Firefox\
You can try a clean reinstall and delete the Firefox program folder before reinstalling a fresh copy of Firefox.
Download a fresh Firefox copy and save the file to the desktop.
*Firefox 16.0.x: http://www.mozilla.org/en-US/firefox/all.html
Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
*Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you will also lose your personal data like bookmarks and passwords from profiles of other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
*It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
*http://kb.mozillazine.org/Uninstalling_Firefox
Your bookmarks and other profile data are stored in the Firefox Profile Folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.
You can also try to rename or delete the prefs.js file and possible numbered prefs-##.js files and a possible user.js file to reset all prefs to the default values.

Got a pop-up from some company that wants me to up-date firefox and change to their browser? Tylerdowner says firefox is old but the update says not

like I said b4, a pop-up says to update firefox and change my browser to theirs, this pop-up did not ID itself in any manner

Hello,
The latest version is 33.0.3. It is always safer '''not''' to trust a dialog that pops up without your interaction.
Assuming your computer isn't infected with malware, a safe way to update is to go to:
* Help (or [[Image: New Fx Menu]] > [[Image: Help-29]]) > About Firefox
Or download a new copy at:
* (stub installer) https://www.mozilla.org/en-US/firefox/new/
* (for different localizations/full installer) https://www.mozilla.org/en-US/firefox/all/
Never give your computer's control to anyone remotely, and don't contact any number unless its from the official website's Contact Us page. If you are worried that your computer has been infected with malware, any one of these forums specializing in malware removal can help you:
* Bleeping Computer - http://www.bleepingcomputer.com/forums
* Spyware Warrior Forums - http://www.spywarewarrior.com/index.php
* SWI Forums - http://www.spywareinfoforum.com/
The people who will answer your questions there will ask you to submit reports from virus/malware scans so that they can determine whether your computer is in fact infected, and the steps you need to take in order to remove the infection.
