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

EDITs

one main cause is now understood it is non standard firefox installs suffering from this look downthread at /questions/815130?page=2#answer-189408 

If you have seen this error you can help firefox developers track down the cause please now see my reply /questions/816780#answer-180759 <-- clickable link ->( if blue)-->


I would treat that with caution. It could well be a message designed to trick you into using an insecure site, next you could find other false security alerts, malware downloads or money demands. At present many users are seeing a genuine firefox generated error message


Unless your installation is already compromised the safest way to upgrade is to use the options from within the Firefox Menus. In Firefox 4 there is still the option to check for updates from

  • Firefox Button -> Help -> About Firefox (Check for Updates)

I think in the near future Firefox will; at least by default; be going over to silent updates, and you will then not need to worry about whether you do have to most uptodate version. Your System information is showing you use Firefox 4.0. There is an update for that out, the standard release is now 4.0.1

Firefox 4.0 - Windows XP 32

This happen from the Help / About menu, nothing to do with an external threat. Apparently it should be an auto-update problem of Firefox, but seem poorly documented. I had to update manually from 4.0 to 4.0.1 by dowloading the new version from Mozzilla. However, my new version now starts checking all add-ons upon start and drive me to the new update page each time I'm starting Firefox

@Chriz

As far as I am aware Firefox 4 should not take you to the add-ons manager each time you start and Firerfox 4 should not be checking compatibility of add-ons on each startup.

Your problem may be slightly different to the original post in this thread, so it may be worth starting your own thread. Are you running separate versions of Firefox but only using a single profile, that may cause similar problems.

I personally do not recognise the message in the thread title. I still consider it should be treated with suspicion. Documentation regarding the autoupdate see

A user with Google Updater (from Google Pack) and Firefox 4 installed gets this error. Google Updater is supposed to be keeping Firefox up to date.

Hi Adisharoon,
Do you have this problem yourself, and do you have Google Updater installed?
( I note Original Poster foxandmoose does not have Google Update listed as an installed plugin )

There are now 94 users reporting this problem in this thread alone. (There are 2 other related threads I am aware of)

It may help is some of you start another thread, you can always link to this one, and try to include additional information such as

  1. what site/s is this happening on
  2. what is apparently generating the message
    ( a screenshot may help )
  3. can you reproduce the result
    • if so how ?
  4. is this blocking your upgrade from say Firefox 4.0 to 4.0.1
  5. have you tried in Troubleshoot Firefox issues using Safe Mode do you still get the problem
  6. please give a full list of all installed plugins

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

This is not an error message I have personally encountered, and I did initially think it may have been generated by thirdparty software.

It appears from what someone else has written that this error may occur if a certificate is not as expected. I surmise this may happen if you get updates from somewhere other than the official site. (OR as part of a blatent malware problem ) The info is not on an ordinary discussion forum, and unnecessary comments there could be considered spam so I will repeat the information almost in its entirety here instead of providing a link:


The

Firefox update mechanism requires that the certificate used by the web site that provides the update information be the certificate that Mozilla has purchased and this prevents certain types of attacks. If there are 5 failures in a row the notification is displayed. Some proxy software spoofs the certificate used to connect to secure web sites which is likely what is going on here.

Please open the error console (tools -> error console), click clear, open Help -> About, and copy / paste any entries displayed in the error console. Thanks


I myself would add that if you do look at the error console information it may be wise to clear all the entries before trying the update option. It would probably also be worth trying in Troubleshoot Firefox issues using Safe Mode - but do not make changes, click continue - and with no other tabs open other than a blank page.

Hi trevishubby,

Thanks for the comment, if this re-occurs and you get further information I hope you will post back again. If we can find out more about when this occurs someone may be able to find the cause.

To find the cause we will first of all need to be able to recreate the problem reliably, to give someone a case to investigate.
