I do not use a proxy server to connect to internet, but Firefox is automatically configured to use the loopback address.

I have a direct connection to the internet and that you do not use a proxy server. Every few weeks, Firefox will automatically reset itself to be configured to use a proxy to the loopback address (127.0.0.1). Manually change to 'No proxy' works, but I have to do so every time I open the browser or even a new tab. The only solution I can find is to create a new profile that gives me a new, clean install of FF, but then I lose all my Add-ons. This has happened several times now and it's extremely frustrating. I have scanned for malware, but have not found any problems.

Hello rjlasser, first of all please make sure that none of your extensions is the origin of the problem (some circumvention of censorship of youtube addons do also use proxies for example).

Otherwise please see How to fix the preferences that will not save for common solutions.

  • Using the loopback address to identify the IPsec peer

    I have two IOS routers and you want to use the loopback address on the remote router as address such peer recommended in documents such as "Configuration with EIGRP and IPX using GRE Tunneling IPSec."

    On the local router, I identify the remote router via its address and loopback on the remote router, I configure crypto MYMAP map interface S0/0 and BRI1/0 (with nothing configured on the other than the IP address loopback interface)

    When I establish an IPsec tunnel from the remote router, it uses the interface S0/0 as its source address.

    I tried to configure card crypto MYMAP on loopback0 instead of BRI1/0 and S0/0, but it did not work.

    How can I get the remote router to use as source address loopback address?

    Thanks in advance for any help offered.

    Try to use the "crypto-loopback address 0.

  • My PC is connected to internet, but Firefox does not connect on the web

    For the last two days, I could not connect to any web site through Firefox. I tried various 'solutions' that seemed logical, but nothing has worked.

    My understanding of my computer / in feneral is limited so excuse me if this explanation seems too long or detailed. I do not know what information might be relevant, so I will write everything down.

    First: my wifi is definitely work, because my phone connects through to this. My PC is certainly connected to the internet that I am able to send and receive mail via Outlook, and I downloaded an album via iTunes.
    Other programs are running too thin.

    I tried to restart my computer.
    I deleted my cookies etc (just in case).
    I ran my anti-virus
    I turned off my Windows Firewall
    I re-set my Firefox

    None of this has worked. My next thought is to uninstall Firefox and re - install it... except that I don't have another browser on my PC. I used to have Chrome on my PC, but it seems to have disappeared during certain windows recent update 8.

    A friend sent me an installer of Chrome, but it did not work - and in any case, I want only Chrome so I can re - download Firefox... getting Chrome is not the solution for me!

    I THINK that Firefox no longer works after that my PC installed updates on a regular basis. By that I mean that a few days earlier, when I went to close my laptop, my only options were "install update and restart" or "install update and close.

    I use Windows 8.1. I feel like the updates must have been the problem, because the moment seems to coincide. I really need to be able to access the web then please please help! Thank you

    Hello, normally these problems are caused by a security/firewall software which does not recognize and therefore blocks the new versions of firefox. If please delete all the rules of the program for firefox to your firewall and let it detect the new version of the browser again.

    Firefox 3.6.6 added a new preference for connection settings, use proxy Panel"system settings", and the default value is the point. " This new preference does not affect most users, because they probably do not have a proxy set in place in their operating system. Therefore, most users should use the setting "no proxy".
