AFTER MAKING OPERA DEFAULT BROWSER FIREFIX CAN'T ACCESS INTERNET

I have used Firefox for my browser for several years but decided to try Opera. After making Opera my default browser Firefox cannot seem to establish a network connection. Is Opera responsible? Is it not possible to use two different browsers?

hi NeilCoy, this shouldn't be related to opera. normally such issues are caused by a firewall/security software which doesn't recognize & therefore blocks new firefox versions and there has just been an update during the last few days. please try to remove all program rules for firefox from your firewall and let it detect the new version of the browser again.

    Why don't you talk to apple and find out if backup exists? That conversation with apple will stop your guessing.

  • I'm stucked on APPLE evolution bar when I restarted my Mac after upgrade to Yosemite. I Can't access on my computer.

    I'm stucked on APPLE evolution bar when I restarted my Mac after upgrade to Yosemite. I Can't access on my computer.

    Good Question.
    I downloaded Yosemite a while ago, but didn¹t install it because it would
    knock out several applications such as Solitaire till Dawn But finally
    when some apps wouldn¹t work with my current version of Safari I thought I
    would upgrade Safari but they wouldn¹t work with the OS I was using so
    suddenly I had no Safari and was worse off than before. So I bit the bullet
    and upgraded to Yosemite with the earlier version I already had. Not pleased
    when iPhoto didn¹t work, and it also coincided with an national email outage
    here in Australia by the major carrier so no email either.
    Experience has taught me that it gets sorted out in the end but in the
    meantime...
    And the lesson is [

    Force close the App Store app and reset the iPad. No data will be lost when you reset the device.
    In order to close apps, you have to drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.
    Next, reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

  • New Ipod Touch 5g can't access Internet in home network (using Linksys E4200 router). But, OK with other Wifi.

    Just bought new Ipod Touch 5g. I found out it can't access Internet in home network. not really cannot access, but very slow to open any web page, App Store failed to access, etc. But, OK with other Wifi (office & starbucks). Others existing iOS devices (Iphone4 & Ipad2) have no problem like this. I'm using Linksys E4200 router at home. anyone has any idea why?

    Try:
    - Reset the iPod. Nothing will be lost
    Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Power off and then back on the router
    - Reset network settings: Settings>GeneralReset>Reset Network Settings

    - Restore from backup
    - Restore to factory settings/new iPod.

  • IPhone 5s can connect to wireless WIFI router but can not access internet.

    iPhone 5s can connect to wireless WIFI router but can not access internet at work. The admin says the router lets my iPhone connect to LAN, but the iPhone does not have server IP to access the internet. I entered the server IP and port number in the HTTP PROXY fields but I still can not access the web. Any ideas?
    TIA
    Rich

    You IT person should be able to sort this out.  But, they seems to be too busy or disinterested to do this.  Suggest you provide the it person with an iPhone to get interested.
    Any could be lots of things.
    The best you can do is to get access to the admin setup for networking on a pc?  The internet settings are all the same.  Only what names the manufactures change from OS to OS. Check and compare parameters.
    Phone works to internet at home, I assume?

    Reply: I spent about an hour last night doing all the things that you suggested including moving the lan cable from my desktop to my laptop which worked fine. When I hoover over the connection it says;  Network3                                                                                        Internet Access   no error messages.When I unplug the cable at the router a red x covers that connection icon.Plug it back in red x goes away.It is seeing the router, just does not appear to be providing selected web page info.Computer thinks it is working fine.

  • I installed a new airport express and made it part of my existing home network...  now the PCs can't access internet through the airport extreme or the cisco access points

    Everything works perfect with Macs, iPhone, iPads but I have 2 pcs that now can't access internet. The PCs connect to the airport and my other access points but no internet- The PCs sent an error of DNS

    Yes, as we already said, it will do all of this if you have a good wireless signal reaching the bedroom.
    Remember that an extender or repeater or whatever you want to call it can only extend the quality of signal that it receives.
    The Ethernet signal that the Express delivers will only be as good as the quality of the wireless connection between the AirPort Extreme and AirPort Express.
    If you have doubts, make sure that you understand the store's return policy before you buy.

  • When making firefox default browser, some print commands in Microsoft programs/games no longer work. example: printing a NAVLOG in Flight Simulator FSX. i have been able to reproduce this error at will. win7 IE9

    basically this is it. In FSX when creating a flightplan there is a print button where you can print (on the PC default printer) the flight plan. (NAVLOG) When Firefox current version is the default browser, this print button simply does not work. Making IE9 (32 bit) the default browser, this print button works again. No doubt this will occur in other applications also but I have only encountered this in FSX sofar.
    I run win7 64 bit but use the 32 bit browser. All patches are up to date. to be clear, this isnt limited to FSX. It affects all Microsoft programs that call the print command in win7. Clearly FF isnt fit for purpose if I cant make it reliably the default browser. anyone else come across this ?

    Sorry if this comes to late, I just now came across this thread.  I have rtorrent and rutorrent sunning successfully on my x64 Arch Linux install.
    Try putting the "SCGIMount /RPC2 127.0.0.1:5000" line in your httpd.conf file right after the LoadModule lines (it's line 124 for me).
    I seem to recall it not working when I put it at the end of the file.
    Best of Luck!

  • Automatic update from microsoft explorer has compromised firefox browser and stopped it from working. How do I get rid of MS update. Already restored to an earlier time, did not work. Firefox is my default browser. Can you help?

    Firefox cannot get to the web because the MS update conflicts with my default browser FF. I tried a system restore point before the explorer 9 update, but it didn't clear the MS update troubleshooter with the FF logo and I can not get to my browser directly.

    I can't help you with that software in particular but I suggest you to try Xpadder, I also have the microsoft xbox 360 gamepad and it works as far as I know

  • Safari locks up when making it default browser

    If I try to make Safari my default browser by going through the setting in Safari it always locks up Safari. I'm then forced to do a force quit on Safari to relaunch it. Anybody have any idea why this would happen? Firefox has gotten strange on me lately, so I want to make Safari my default one until I can figure out what's up with Firefox.

    Hi Barry,
    Sorry for the delay in saying thanks for the help. I ended up rebuilding the launch services database that cured that problem and another one I had. I do really appreciate your help.
    Many thanks again,
    Mike

  • Can't access internet since I set Firefox as my default, I could before. Set firefox as exception to firewall, even tried disabling firewall totally. Still can't get service on my other computer.

    I was able to access firefox before I set it as my default browser.Have called my internet company but they were not able to help. I can access email just fine so I know my connection is fine. I have tried deleting history, cookies, etc. I have tried unplugging modem and restarting.

    When going to a website the picture was small - tried changing the Zoom size , tried Zoom Reset - the text did change size but the layout distorts - found under View - Zoom - Zoom Text Only was checked --- Removed this check mark and the website returned to normal size and Zoom worked normally again. I am 99.9999% sure I did NOT check this myself and there is no one else on the computer to cause it. Maybe this will help.
