Firefox does not connect to internet

Message arrives... "proxy server refused connection" How can I change this?

Is what happens when you're on mobile data? Connected to WiFi? You are using a firewall or other security software on your Android device?

  • Firefox is not connect to internet unless the reboot

    So, recently, I had a problem with Firefox does not connect to internet unless I quit and reopen the app.
    It happens like this:
    -J' open Firefox and it works;
    -I lose the internet connection (for example, I turn off my wifi, or my laptop goes to sleep);
    -J' I reconnect to the internet.
    -Open Firefox browser will not connect to what it is and continues to load when I click a link
    -J' I need exit Firefox and restart it before starting work again.

    It doesn't go to my other browsers (Safari, Chrome), once I have reconnect to the internet open browser will just continue to work without needing to be restarted.

    Is not a big deal, but it's a bit annoying and I would like to know if there is anything I can do about it.

  • Firefox does not connect to any site since the new update to download.

    Firefox does not connect to all websites since the installation of the last update. Google Chrome and Internet work.

    Some problems occurs when your Internet security program was set to trust to the
    a previous version of Firefox, but no longer recognizes your updated as version
    level of confidence. Now how do I solve the problem: to allow Firefox to connect to the Internet
    Once again;

    • Make sure your Internet security software is up-to-date (for example, you are using the latest version)
    • Delete Firefox to list your program of trusted or recognized programs, then add it again. For detailed instructions, see

  • Firefox does not connect to any Web site, but other browsers will.

    When I get something in the URL- google.com, localhost, http://127.0.0.1/ one bar the IP address, there is a fraction of a second flash, then the bar becomes empty and nothing has changed. It seems that Firefox is not even try to connect to the internet.

    Yesterday, everything was fine when I was running FF on Windows 7. After the upgrade to Windows Pro 8, Firefox has failed. I've updated for Windows 8.1, hoping for the best, but it's the same problem.

    I've walked by the firewall program, several times (the only race is the built-in Windows Firewall). Finally, I uninstalled Firefox, including all my settings, custom and reinstalled from scratch, twice. And even this version pure and clean Firefox does not connect to the internet.

    I am a computer web developer and would be happy to look at the log files or run a tool (Fiddler?) to see what happens at a low level, if I only knew where to look.

    john99, thanks for the links. I went through all (again), one by one. The last link kb.mozillazine.org/Standard_diagnostic showed me what helped. I've renamed "firefox.exe" to "firefox1.exe" and was able to use firefox.

    It made me suspect the firewall or malicious software. I ran a Malwarebytes full scan, zero problems detected. I have pored on the entries of windows firewall, the "Windows Firewall with advanced security" view and also the simple control panel view. The only mention of Firefox is that I continue to add and remove to allow firefox through.

    Here I knew what was going on, but for now, I can at least use firefox. How frustrating!

    We cannot verify that Windows Update is causing the problem, I suggest to install the Windows updates one by one and make sure that Windows Update is causing the problem.

    Update: I indeed found firewall was the issue (the first time with updates of Firefox). I tried uninstalling and reinstalling, but that no longer works.
    Then I opened the application window of Norton Security (looking for information of firewall). I don't actually change or click on what to Norton. I decided to try to install again. This time, when I hit "Run" instead of "Save", the small window Norton popped up saying downloading is safe. Then he installed and opens very well.

    It may be a quirk of Norton? Or by choosing run rather than save (and running after registration)?

  • iPhone connects to the wifi but does not connect to internet

    I have an iPhone running iOS 9.3.2 6s (last updated).

    The phone connects to the wifi network, but even if it's to show the signal strength is good, the phone does not charge any internet content (weather, FaceBook, email, etc.).  If I disconnect WiFi and use the data, it works very well.  We have no problem connecting to the computer or a smart TV network wifi and internet connection.

    This also happens with my daughter 5s iPhone and iPad for my son.

    Sometimes it will work fine on wifi, then a little while later I can't get anything to load. And it can be like right now when I'm at home alone is not as if there's a big load on our wifi.

    We have high-speed internet by cable (25 MB/s download speed) and a router Lynksys EA3500.  Encryption is set to WPA (not WEP).

    I tried to go into my phone settings and reset the network.  Always problems.

    It's really frustrating because you eventually switch to our mobile data and use it instead of our data ' wifi '.  And then to go on our data on our phone plan

    Here's a tip for the user on the problems of Wi - Fi. Suggest from the top and bottom. Maybe one of them will help you.

    (1) perform a forced reboot: hold the Home and Sleep/Wake buttons simultaneously for about 15-20 seconds, until the Apple logo appears. Leave the device to reboot.

    (2) resetting the network settings: settings > general > reset > reset network settings. Join the network again.

    (3) reboot router/Modem: unplug power for 2 minutes and reconnect. Update the Firmware on the router (support Web site of the manufacturer for a new FW check). Also try different bands (2.4 GHz and 5 GHz) and different bandwidths (recommended for 2.4 to 20 MHz bandwidth).

    (4) change of Google DNS: settings > Wi - Fi > click the network, delete all the numbers under DNS and enter 8.8.8.8 or otherwise 8.8.4.4

    (5) disable the prioritization of device on the router if this feature is available. Also turn off all apps to VPN and retest the Wi - Fi.

    (6) determine if other wireless network devices work well (other iOS devices, Mac, PC).

    (7) try the device on another network, i.e., neighbors, the public coffee house, etc.

    (8) backup and restore the device using iTunes (ask for more details if you wish).

    (9) go to the Apple Store for the evaluation of the material.

  • HP Pavilion dv7 - 3188cl: HP Pavilion does not connect to Internet (resolved)

    I recently got a HP Pavillion Entertainment, model number dv7 - 3188cl, for me to use for a class at the school by my uncle. Before the recovery, everything worked perfectly well. My uncle asked me to reset the computer, so we used the recovery disks that wiped the hard drive successfully but then refuses to reinstall the operating system. Instead of getting another set of recovery disks that I've used a Windows 7 install disc to reinstall the OS and he did so successfully with one flaw, the laptop does not connect to the internet.

    I tried to connect via ethernet and it does not find my WiFi network. I suspect his lack a driver and checked for drivers on the HP site but he said that there is none. Any advice would be greatly appreciated, and if there is no driver for this I would be grateful if you could tell me where to download from.

    Thanks in advance.

    Update: after some search Intel had the good driver needed.

  • Satellite L350 - does not connect to internet

    Hiya all

    Had the laptop about 3 months now and still connected fine to my wireless internet. But recently he has stopped to connect to wireless internet.
    I can't find my wifi connection, but it does not connect to it. My parents have the same laptop, purchased at the same time and can use it on the same wifi with no problems.
    My sister has also no problems to connect to my wifi on his cell phone, neither does my Xbox 360 or my iPod Touch.
    I can connect my laptop directly via ethernet to the router, but it's not ideal for me, and also I couldn't find automatic updates to download.

    Can someone help me with this please?

    Thank you very much!
    Ethan

    Good luck!

  • iPhone and iPad does not connect to internet

    Hello

    Since yesterday, I was unable to connect to internet via wifi on my iPad and iPhone.  They show the power of the full signal and says I'm connected, but won't load Web pages or refresh applications.  When I disable wifi on my phone everything works fine on the LTE, but I don't want to use my data.

    I think it must be something with the update iOS because:

    -J' completely rebooted our router and modem and it worked on my iPad for about 30 seconds (what makes a Web page) before it stopped working again.

    -My boyfriend did not the last update on the iPad or iPhone, and both connect on our wifi at home, while my iPad or iPhone will connect to the internet.

    -My iPhone also does not connect to the wifi in my work, even though I know it works as I am online on my computer work via wifi.

    I noticed something strange on my iPhone and iPad when I went to check the settings wifi yesterday - the VPN configuration is flashing/refreshing without touching me, even if I don't have everything set up VPN connections.  When I actually click on VPN, an error is displayed.  There may be something wrong with the VPN on the new update which blocks the wifi signal?


    I really appreciate your help!

    If you are able to connect your iPad and iPhone to your wireless router agreement but the iPad and iPhone will not connect to internet, it is unlikely to have anything to do with the version of iOS.

    Try this:

    Restart your router (unplug unit, wait ten seconds and then reconnect it).

    Wait for the router shows all lights normal and connected.

    Now, reboot your iPad or iPhone
