Firefox cannot connect to servers after updating my computer.

I have vista. When I read comments from aid. They were for XP. I have no tools options / Advanced tab click on what I can find. I have access to internet via outlook. Also my Email has been giving me error messages. I had not used my computer in over 2 months, so I got a lot of updates not only Firefox.

One possible cause is security software (firewall) that blocks or limits Firefox or plugin-container process without informing you, possibly after the detection of changes (update) for the Firefox program.

Delete all rules for Firefox in the list of permissions in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

  • XP systems cannot connect to internet after updates applied over the weekend (10/29 - 10/31)

    Systems: Dell Optiplex 740

    Operating system: XP Pro, SP3.  Connected to the AD network.

    Antivirus: Symantec Endpoint Protection

    : Systems imaged with Symantec Solution Suite 2.5, running ghost console client, run office 2007, LotusNotes email client, Adobe Acrobat 9.0 pro, no odd/specialty software.

    The following hotfixes have been automatically downloaded and installed this weekend.  (The domain value autoinstall updated policy)

    KB2296011 KB2345886 KB2360937, KB2378111, KB2387149, KB982132, KB979687, KB981957, KB2279986, KB2360131, KB2418241

    System ran perfectly before the updates above being installed, applied.

    Symptoms:

    1 - log on to the network, sometimes connection takes hours (2-3) to load a new or existing profile.  This seems random, as some profiles allow an immediate connection.
    2 - the system does not stop.  Even if gone for 16 hours, it never completes the task.
    3. can access local systems within the network through a UNC path, but very very slow.  Can ping anywhere, ping also solves dns IP (google.com, yahoo.com, etc.).  Can't access a Web page than IE.  Curiously, install google chrome or any other browser allows web access - never through IE, however.
    4. can not view or change the connections of the network adapters.  Hangs and never completed the task.
    5 USB devices not already connected to the workstation before above patches do not load/install, even if they were previously on this system.  For example, a USB key that worked Friday does today.
    6 - when the screensaver activates, system is not sometimes recover.
    7 - safe mode with networking will run without problem.  IE works, connects to the web.  No hardware problem, no connectivity issues.

    Here is what I have tried, in all possible and combination orders:

    1. remove each patch listed above.
    2. remove each patch listed above AND any referenced patch.
    3 reinstall the SP3.
    4. remove each piece of software other than the operating system.
    5 - disable all services that do not work in safe mode with network.
    6. Remove and reinstall the NIC drivers.

    I am at a loss.  I have an image before the explosion, and it works perfectly until these patches are downloaded and installed.  After the restart, bam.  So, I can easily reproduce the problem.

    Does anyone have any ideas or clues as to what to try?

    Error message after you install an update of Windows Internet Explorer from Windows Update or from Microsoft Update: "cannot display the Web page":
    http://support.Microsoft.com/kb/942818

    If tweaking your third-party provider (i.e., Symantec Endpoint Protection) the firewall settings don't help, try the following:

    1. disable all components Symantec Endpoint AND THEN make sure that the Windows Firewall is enabled.

    NB: Now you're "working without a net": no to ANYTHING else online (e.g., navigation, reading e-mail, chat) until you have completed step #5 below.

    2 Uninstall "a security update for Windows Internet Explorer 7 (or 8) (2360131)" [or "for Windows XP security update (2360131)" If IE6] via Add/Remove Programs (make sure the box show updates at the top right) and reboot.

    3 d - c #1 above.

    4. open Internet Explorer (only) to http://windowsupdate.microsoft.com . Select CUSTOM and scan | Install all security critical updates available (e.g., KB2360131).  If an update of root certificates is listed (possibly in the category of the optional software updates on the left side of the scan results window), install it to enjoy enhanced Internet Explorer security.

    5 reboot & make sure that all in #1 above is activated again and, if necessary, disable the Windows Firewall and enable your third-party firewall.

  • Firefox cannot connect to internet after some time to be on

    Hello

    I posted this question some time ago and since I don't have any solution for work and I still have this problem, I am reposting now. My problem is simple: I start my computer and open Firefox. I browse the internet normally. No problems so far. But lets say I'm going to take a NAP or I stop just from browsing for something else on the computer without closing Firefox or whatever. After a while, I go back to browsing the Firefox (the same window with the same tabs are always open) but now no page will finish loading regardless of how long wait.

    I close Firefox and open it again. Next, I get an error popup stating that Firefox is still ongoing and I need to shut it down. When I close this pop-up window then I get another error saying it is impossible to load my profile. I got that close and reopen Firefox. Now, it loads pages normally again but only for 1 or 2 minutes, and no more after that. I repeat the process and I still get the same results until I restart my computer.

    I checked for any viruses and I have nothing at all, and there is absolutely no problem with my overall connection since no other programs have this problems only Firefox. What can I do?

    Thank you.

    IM Edit: The problem right now and I just checked but looks like some tabs to work and others do not so I don't really understand.

  • Cannot connect to iTunes after update to iOS 10

    First of all I have to say: Apple software is the same loss of time such as Windows or Microsoft. Since the update to iOS 10 I can't connect to iTunes with iPhone 6 Plus. Message: Please accept the new TERMS. Once accepted, it nothing happens. Login and download on my pc windows and itunes works fine.

    When I see the smiling faces at the entrance of the support section I want to beat in every unique face on this page. Apple wants to convey the ease of use of apple software. I do not think, therefore, huge waste of time to solve the problems with it. Another very good example is the WIFI syncing between iPhone and iTunes (PC).

    It was my last iPhone and I went back to android, byebye thx

    If your device does not appear in iTunes, try Re: itunes problem.

  • Why my iphone is required to connect to itunes after updating wireless.

    Why my iphone is required to connect to itunes after updating wireless?

    I don't have itunes and won't.

    Is there anyway around of this or take it back to the old ios?

    More than the upgrade of the air seems to have issues, whether all connect at the same time or other problems. I had to plug my phone into the computer, update itunes to the latest, published today, then ios upgrade 10.0.1 and it is fine now. You could bring to the apple store and probably use their computers, just don't tell the computer to trust the phone.

  • Cannot connect to internet after auto update under Vista.

    Original title: System shows the connection, but cannot connect

    After an automatic update in Vista in mid-August I can no longer connect to the internet.  My system tray shows that I am connected but I can't.  I'm on a DSL wireless connection with a desktop computer (one does not) and a laptop with XP that always works very well.  I re - configure the modem, uninstalled, and reinstalled the wireless card, has run an anti-virus in safemode, uninstalled the Qwest connection network and re-installed AND uninstalled the update to Vista.  I even tried the system restore to an earlier time.  Nothing.  Internet diagnosis says that it cannot solve the problem.  I have read other forums on the UN-checing proxy settings but mine have not been verified.  I re-set my settings IE8 by default.  Uninstall protection against viruses...
