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)

I got this message:" Software Update Update failed Something is trying to trick Firefox into accepting an insecure update. Please contact your network provider and seek help." What on earth is this about? I am not computer savy.

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.

OS is Win Vista
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.<br />
Do a clean reinstall and be sure to remove the Firefox program folder.<br />

My Macbook Pro will not print anything from any program. I've reinstalled the drivers. I get an error message in Word that says, "Word could not communicate with printer." Any ideas?
Be sure to try restarting, if you have not done so since this problem occurred. You should also power off the printer while you do the restart...
If that does not help, you can try resetting the printing system. Open System Preferences Print & Scan (or Print & Fax) pane. In the sidebar with list of printers, right (control) click anywhere. Select Reset printing system. You will have to add back your printers after you do this. -
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.

I tried to install an itunes update yesterday on my Dell Laptop. I kept getting an error message. Now I cannot access itunes and it says I need to reinstall itunes. Will I lose all of my music?
Installing, and uninstalling, applications never touches or removes the data.
Clean out and uninstall all the apple programs and software thru Programs and manually.
Might want to use Revo and CCleaner
I always use manual standalone installers (and keep a couple backup versions)
itunes 10.5 may affect iTunes media playlists, not sure, depends on what you have.
A search of these forums will show some threads.
I'd clean up vista, you need SP2 or later, and specific error message?
I wonder as you arenot the first with a dell if maybe the OS or included software.
Security programs like Norton and older versions of Kaspersky have been implicated.
Also settings in IE that affect pop-ups and plug-ins. -

When I try to access Apple Support or discussions, I get the following error message:
Attention, Internet Explorer 6 User
Announcement: Jive has discontinued support for Internet Explorer 6.
In order to provide the best platform for continued innovation, Jive no longer supports Internet Explorer 6.
Jive will not function with this version of Internet Explorer. Please consider upgrading to Internet Explorer 7, 8, or 9, or trying another browser such as Firefox, Safari, or Google Chrome.
(Please remember to honor your company's IT policies before installing new software!)
I'm not using IE6 — I'm on an Intel Mac Pro!! What is going on?hello, the useragent of your browser is correctly identifying it as firefox 31. you'll probably have to approach apple's support to find out if they have a bug on their side or are displaying this message to all its users...

When I finished backing up my iphone 5 to my hp pavilion laptop I got an error message R6034. Itunes shut down and I have not been able to reinstall it. The error message says an application has made an attempt to load the C runtime library incorrectly. My computer is more than 5 years old and I have never had this problem before. I tried unsuccessfully to reinstall itunes. Any ideas?

There are folks that send me emails all the time. Sometimes they come in and most times they don't They are always telling me that they sent me an email and I have not received it. When I tell them to send it NOW as I am sitting at the computer, then the email comes in for the first time. This has been happening since I downloaded Thunderbird. Please tell me why this happens as it if a bit frustrating, especially when they don't know I have not received their email and the information is very important that I get the email and the information they are sending me.
Thank you for your assistance.
barbi saundersThunderbird downloads email messages that make it into your Inbox on your providers server. Are these missing messages actually in the Inbox and are not downloaded or do they not make it to the Inbox on the server.
If the later, ask your provider where your mail is going.
It might not hurt to log into your account on the server and check for a spam folder. You might be surprised to see what is in there. -
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.

1 - I have run Disk Warrior.
2 - I have repaired permissions.
3 - I have deleted all plist that are either Cannon or Adobe.

Every time I sign into my Macbook, I get an error message from Automator; "The data couldn't be read because it has been corrupted.". I have never created an Automator workflow. How do I find out what Automator is trying to run and stop it?
Maybe it's set as a login item:
- System Preferences: Users and Groups:
- Highlight your user account in the left pane/list
- Click "Login" tab at the top.
See if you have an Automater action on the list
- Note, you can select it, then right-click, and can then select "Reveal in Finder". That way you might have an idea what installed it.
