Beginning last week, Firefox will not connect to the internet.

Firefox will not access the internet at all. This began suddenly and not immediately following a change in Firefox or my computer.

Maybe you have a malware infection.

Do a malware check with some malware scanning programs. 
You need to scan with all programs because each program detects different malware. 
Make sure that you update each program to get the latest version of their databases before doing a scan.

The last week, Firefox will not load up the NEW YORK TIMES. So, I have had to use Safari to do so. If this continues, I'm going to quit using your browser, and begin using Safari all the time!

There are several other similar posts in this forum with the answers. Your post appears third in my Google search today looking for a solution so I thought I'd add the solution here as well.
It is obviously a bug in either (or both) Firefox and the NYT.
The quickest solution is to simply go to the VIEW Menu in Firefox, then the ZOOM option and choose RESET.
I use Mac and this happens in Firefox 3.6.10. It does not happen in other browsers like Safari, Chrome and Camino, and it did not occur before last week.
It has also occurred in the iOS version of Safari on iPad. Not sure how to fix it there.

After updating to Firefox 3.6.15, Firefox will not connect to the Internet, even after uninstalling and re-installing Firefox in my Windows XP environment.

After downloading the Firefox 3.6.15 update, my problems began. Firefox would not connect to the Internet. When I rebooted my PC, Firefox said that it couldn't access any Web sites. I uninstalled Firefox, then downloaded and installed Firefox 3.6.15. I still have the same problem: Firefox will not connect to the Internet. I am running Windows XP, service pack 3. I never had problems with Firefox until I installed version 3.6.15.

I have XP Pro. I tried installing 3.6.15 and could not open it. I did a system restore and 3.6.14 would no longer open. I tried again installing 3.6.15 and got a message that the previous version had not uninstalled properly. Tried uninstalling.
As a precaution I used MozBackup to save my bookmarks etc. and also saved a system restore point.
I then clicked Start, My Computer, drive C, Program Files and deleted the Firefox folder.
I installed 3.6.15 and it is now working fine with all my bookmarks and addons loaded automatically.

Firefox performed an automatic update on my machine and now my firefox will not connect to the internet

Firefox will not connect to the Internet anymore. What do I do?

''duplicate - locking - https://support.mozilla.com/en-US/questions/894256''
I was prompted to update FF. Afterwards, it wouldn't connect to the Internet. Windows Explorer still does though. I did System Restore, Uninstalled and Reinstalled FF without avail. The problem still persists! I hate Explorer and want my FF back ASAP. H E L P Pls.

Try the following solutions and whichever setting works, keep it Permanent:
1) go to Tools Menu -> Options -> Advanced -> Network -> click '''Settings...''' button infront of Connection -> select option1 -> Click OK -> OK
2) go to Tools Menu -> Options -> Advanced -> Network -> click '''Settings...''' button infront of Connection -> select option2 -> Click OK -> OK
3) go to Tools Menu -> Options -> Advanced -> Network -> click '''Settings...''' button infront of Connection -> select option3 -> Click OK -> OK

Firefox will not connect to the internet.

When I try to connect with firefox it gives me the message that firefox was unable to connect to the server that I was attemting to connect to, and then it asks me if I would like to try agian. I still have internet explorer on my computer and it connects just fine. I need to have firefox working, or I will have to go with google chrome or something different, as internet explorer is not recomended to use on most online college applications and it is finals week.

Windows 7 has a firewall which controls access to the internet on a program by program basis. It is possible that Firefox is not in the firewall's list of a approved programs.
Go to the Help feature and search on Firewall and read the information on how to allow a program internet access.
I don't use the Windows 7 firewall, I use ZoneAlarm's firewall. When I installed ZoneAlarm, I disabled the Windows 7 firewall and have never used. Thus, I can't give you detailed directions as to what you might need to do to allow Firefox to use the internet.
NOW - are you able to get to the internet with Internet Explorer, just as a test?
If not, then the problem may be elsewhere, such as your internet connection - dialup, DSL, Cable, etc.

Firefox will not connect to the internet, but I can still load Internet Explorer and use it to browse.

I alredy tried a deinstall and reinstall
Attempted to configure internet settings, not sure if I did it right.

My Macbook Pro will recognize my network but will not connect to the internet

My macbook will not connect to the internet at home. It works fine on other networks, but at home it will recognize my network name but says it will not be able to connect to the internet. This issue just sort of came up randomly. I have shut the router off (I use Verizon Vios) and reset it and that doesn't work. The little Wifi status at the top of the screen just has an exclamation point over it. I haven't changed any of the default network settings. It just stopped working. When I take it to work and use their network or free wifi available at stores etc...it connects just fine. A few weeks ago upgraded my operating system to Mavericks, but it has worked up until this morning.

Do this. Go to Apple menu / System Preferences / Network.
In the left column, click Wi-Fi. Next click Assist me, then Assistant. Follow the on screen instructions.

My laptop compaq presario will not connect to the Internet anymore after buying airport extreme. Why? It detects the network, accepts my password, but will not connect to Internet.

My laptop compaq presario will not connect to the Internet anymore after buying airport extreme. Why? It detects the network, accepts my password, but will not connect to Internet. I tried to repair connection, tried to reboot modem several times, I even updated my computer. Nothing. All it says is that it does not detect modem. Why?

Welcome to the support community group.
First, are you sure that your AirPort Extreme has been configured correctly and is properly connected to your modem?
Begin by telling us how you have things connected and if the Airport Extreme is replacing a previously owned router or is this an entirely new installation?
First be sure that your modem is working and properly connects you to the internet using an ethernet cable directly connected to your laptop. Once you're sure that's working, reset the AirPort to factory defaults by disconnecting it from power and pressing and holding in the small reset button on the back for 15 - 20 seconds while you reconnect it to power. Then turn everything off for 5 minutes. Connect the Airport to your modem with and ethernet cable to the Airport WAN port on the back (check the user guide to make sure you connect the cable to the correct port) then connect a second ethernet cable between the laptop and one of the LAN ports on the AirPort Extreme.
Then power up the modem first, wait 5 minutes and then power up the Airport, wait 5 minutes and finally power up your laptop.
Then run the airport configuration utility from your laptop. Since you're not using an Apple computer, be sure that all of your firewall, and virus blocking and checking software is disabled before you run the airport configuration utility. Once you run the utility, it should detect your AirPort and allow you to use the configuration wizard to set things up.
Check back if you're still having problems.

Ipad will not connect to the internet?

My iPad has been working fine for a year on my WiFi, but suddenly will not connect to the internet. Both my laptop and desktop connect just fine. I have tried rebooting, resetting and deleting the WiFi connection to reestablish it, but nothing has worked

This isn't my forte' but resetting the router often works. We have 2 Ipad 1s and over the last year and a half maybe 3x one of them wouldn't connect. If I reset the router, even without doing anything other than check the connection in settings, it would reconnect and be fine for months and months, Worth a try,

Safari will not connect to the internet

Safari will not connect to the internet on both a G5 and a MacBookPro that are routed through the same server.
All networks settings are good
DHCP is working
DNS is correct
IP is right
Gateway is right
The network can see the macs and the macs can see the network......but the macs can't see the internet.

Hi Duncan
MacFixit recently posted a report for subscribers testing 3rd party routers for Mac compatibility. 3 Routers did not do very well in the test:
From their report:
Routers:
MacSense [Fair]
Expressed support for Macs
Somewhat confusing process for installing firmware updates under Mac OS X
Manuals still show only Mac OS 9 screenshots/instruction
D-Link [Fair]
Mac-specific section on Web site with ostensibly compatible routers
Lack of Mac technical support
Firmware updates appear to apply specifically to Windows-related issues
Mac-specific "Quick Install" guides missing for most wireless router models -- even those listed in the Mac section
Some routers must be configured only with Firefox or an alternative browser -- Safari will not work
Reader comment: "I recently exchanged email with their tech support and was specifically informed that D-Link does not support Macs for any of their products and specifically does not recommend their use on Macs. Although many D-Link products will work on a Mac, as a user you are on your own. D-Link will not provide any direct or indirect support according to their tech support."
Linksys [Poor]
Technically Mac-compatible but lacking in Mac-specific documentation or setup software
No Mac technical support
Thought this info might be useful as you look into your router situation.

Hi All, My MacBook will not connect to the internet at my apartment.

Hi All, My MacBook will not connect to the internet at my apartment. I live with 5 other people and it works for all of them. It worked for me until about 3 weeks ago. My internet works fine at other places like cafes or other folks' homes. I've tried many things but am having no luck at all. If anyone has any suggestions, I would love to hear them! Thanks!

Some routers (such as my Netgear) seem to work better if you input your device's MAC address manually while on their online site. That site address should be in the manual and usually starts with something like 192.168.x.x Once on that site, input your Mac's address - a series of numbers and letters i.e. 2f.3c.45.2a.xx.xx (go to Network Preference Pane, select Airport, click on Options: at the bottom it shows "airport ID". I have all my devices listed; with that you can create a special IP address i.e.192.168.1.1, .2, .3, and so on. I've never lost connection using that method.

My ipad recognizes my home network but will not connect to the internet. When I click on AirPort/preferences at the top of the imac screen it says..."AirPort has a self-assigned ip address and may not connect to the internet".How can I change ip address?

My ipad recognizes my home network but will not connect to the internet. When I click on AirPort/preferences at the top of the imac screen it says..."AirPort has a self-assigned ip address and may not connect to the internet". If this is the root of the problem,how can I change ip address?
Ipad will connect no problem to other networks.

First thing you need I think is to get your iMac connected to the Internet.
Shut down your iMac and you iPad. Then power off your router. Wait 30 seconds and power up the router.
After the router indicates that it is connected to the Internet then start up your iMac and see if it connects. If the iMac connects to the Internet then your iPad should too.
If this power up sequence doesn't work you'll have to dig into the router setup to make sure it is working properly.

Beginning last week, Firefox will not connect to the internet.
