My firefox browser will not connect (to any site)/ problem loading page

It used to work just fine and suddenly crashed. I tried creating a new profile, but it would not load the profile manager either. I have also tried uninstalling and reinstalling it to no avail.

Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do not click the Reset button on the Safe mode start window or otherwise make changes.
*https://support.mozilla.org/kb/Safe+Mode
You can use one of these to start Firefox in <u>Safe mode</u>:
*On Windows, hold down the Shift key while starting Firefox with a double-click on the Firefox desktop shortcut
*On Mac, hold down the Options key while starting Firefox
*Help > Restart with Add-ons Disabled
If it does work in Firefox Safe-mode then disable all extensions (Tools > Add-ons > Extensions) and then try to find which is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

  • When I open Firefox, The tab keeps quickly flicking between "Connecting" and "New Tab". The browser will not connect to any site.

    This occurred straight after visiting the isohunt site. I had a message saying "Firefox is preventing
    IsoHunt from installing a program, will you allow?" (or words to that effect). I gave permission then the problem started.
    I have used Firefox on my iMac for a long time without any problem. I'm running OS X 10.7.5
    Hope you can help

  • Firefox will not connect to any site since downloading new upgrade.

    Firefox will not connect to any websites since installing the latest upgrade. Google Chrome and Internet do work.

    Some problems occurs when your Internet security program was set to trust the
    previous version of Firefox, but no longer recognizes your updated version as
    trusted. Now how to fix the problem: To allow Firefox to connect to the Internet
    again;
    * Make sure your Internet security software is up-to-date (i.e. you are running the latest version)
    * Remove Firefox from your program's list of trusted or recognized programs, then add it back. For detailed instructions, see

  • Firefox will not connect to any website but other browsers can

    I installed firefox on my new advent laptop running windows 7 but it will not connect to any websites. I can connect using chrome or ie no problem but i always preferred firefox as a browser, i have tried changing settings and turning off my firewall but still having no luck

    Okay, here is my answer to this problem. At least it fixed my problem and firefox now works fine.
    Prior to this problem I was running zonealarm (free firewall) everything worked fine until I removed zonealarm free and installed Comodo free firewall. That is when the trouble started. firefox failed and IE kept working. I tried everything posted here nothing worked for me.
    I resorted to "REGEDIT" and removed everything in my registry that regedit would allow that had the name of "zonealarm" on it. Didn't even have to reboot my system, firefox worked first thing. Everything else is fine also.
    [note: this is not a slam against Lavasoft's ZoneAlarm firewall. It is just that UNINSTALL programs do not always do a thorough job of removing parts of programs in your systems and registry cleaner programs do not pick them up either.]
    USE CARE, "REGEDIT" IS A POWERFUL AND DANGEROUS TOOL TO USE ESPECIALLY IF YOU ARE NOT A SOMEWHAT ADVANCED USER. USE CARE WITH "REGEDIT!"
    Good luck.

  • I've been working on our church website and suddenly, my computer will not connect to the site. I keep getting a message saying that the the connection to the server was reset while the page was loading. Does anyone have any ideas of how I can fix this?

    I've been working on our church website and all of a sudden this week, my computer will not connect to the site. I keep getting a message saying that the the connection to the server was reset while the page was loading. Does anyone have any ideas of how I can fix this?

    The "The connection was reset" error message can be caused by a bug fix for the BEAST (Browser Exploit Against SSL/TLS) attack that the server doesn't handle.

    you have definitely tried the correct steps, all you would need to do now is a back up & restore to factory settings. If after that the issue remains then you would most likely need a replacement unit.

  • My browser will not connect to the internet

    my safari browser will not connect to the internet

    Are you on your home internet or a hotspot?
    If you're at home, try to power cycle the router. Unplug the router, count to ten, plug it back and let it boot up and try again.
    If you're on a hotspot, most of them have a 'terms and conditions' page that you have to agree to to actually join the internet. And the page doesn't always some up on its own and you have to trick it. Try to open your safari then go to some new address - usually someplace common like google or yahoo and see if that triggers the auto load of the terms page.
    If you have another browser, you can give that a try. I've noticed with iOS8 that the script to make the terms pages come up don't always run right, but if I use another browser I have on my iPad it will load right with those.
