Why can't I access the internet through Firefox?

I can't access the internet through Firefox. It's worked just fine for several years, but it just randomly quit working. I've tried resetting Firefox, uninstalling an reinstalling it, and allowing Firefox through the firewall.

Did you try to remove the current rules for Firefox in the firewall to make ure to create new rules for the current Firefox release?

Why can't I access the Internet since Firefox updated?

When I went to open Firefox on may laptop I got a box that said - Firefox will start in a minute after it finishes updating (not verbatim). After it opened I can't access the Internet through it or use any of my quick links. It just keeps refreshing to the Firefox homepage.

Okay, lets start over. What is the system you are running?
Win, Mac, Linux . . . . . . Version
What Firefox?
Are other programs accessing the web?
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. For detailed instructions, see

Why can one mac access the internet and not the other?

Hi I have just installed a 2nd generation Airport Express base station. I have setup a network and I can connect to it to access the web. Here's the rub, only my Macbook Pro can connect. My Macbook Air cannot connect? A weird error message says (translated from Swedish): Airport has the selfapplied/selfselected IP adress 169.254.67.130 and will not be able to connect to the internet.
Why can one mac access the internet and not the other? Is there something simple that I can do to get more macs to be able to use my Airport Express to access the internet?
Tech details:
Airport Express 2nd generation (just purchased) model 1392
Macbook Pro running 10.8.2
MacBook Air running 10.6.8

It seems the Airbook assigns a dummy IP address so somehow it doesn't reach and receive an IP from the Express. I deleted the previous Express setting restarted the Air connected again, restarted the modem, restarted the Express nothing....
I spoke to the internet provider and the cable modem does not require any username or pw. from the modem to the cable it's one public ip, pure internet is flowing from the modem to the Express but the express doesn't seem to assign any IP address apart from the one assigned to the Macbook Pro.
Do you need a screendump of the settings on the functioning Mac or the faulty one? What settings are you interested in i.e. which tab should it shot?

Why can't I access the internet and everyone in my house can?

My laptop was getting signal since I moved into this house in the Summer. I went home to LA for a few days and when I came back one of my housemates got a new modem. Everyone else's laptop work(including 3 other mac book owners) fine but I cannot get access to the internet. What do I need to change or do? Im not so great with technology but I tried different options, she took off and on the password from the wireless internet and nothing. As well, I noticed 2 other icons at the top of my laptop next to the battery life icon..One looks rectangular and black..and the other one looks like this <.....>. Weeks have passed by and I'm just getting tired of having only access to the internet in school.
Thanks! Hope someone can help me because I need it for school.

What did not work?
Did the airport router you are trying to connect to not show up under the airport symbol in the menubar?
If it did show up, did it have any symbols by it like a padlock for instance?
In other words, exactly what did you do and exactly what did you experience?
If your Mac does not even list the router in the menubar under the icon/symbol (triangle with curved lines, supposed to appear to be radio waves radiating) then the router may have a setting set that does not allow it to be seen except to computers with MAC addresses that have been entered into it as allowable. If this is the case then your MAC address will have to be entered into the router's list. MAC stands for Media Access Control. "Mac" is the abbreviation for Macintosh.
The fact that you mention you have two new symbols in your menu bar suggests that someone has been playing with the computer and making changes that you are unaware of. If this is the case then there are many possibilities for problems.
The fact is, a Mac fresh out of the box will see any router within range and connect to it unless the router requires a password or the router has Access Control set such that it cannot be seen by a computer that does not exist in its 'OK' list. Since yours works at school, that rules out a hardware or problem or most software problems with your computer. But networking is complicated enough that you have to be quite specific when you try to tell others what you have tried and what results you got.

Why can't I access the internet via ethernet port on my Airport Express?

I have an Airport Extreme base station and two Airport Express units. The Extreme is connected by ethernet to a BT Home Hub (BT is the internet provider). The network works for all the other computers that have Airport cards BUT I want to connect a Mac Mini (no airport card) by ethernet to the Express, but no matter how I try re-jigging the settings on the base station and Express, it won't connect. Mac Mini WILL connect when wired directly to the Extreme base station, so it's not the port. Also, I have been able to stream iTunes to the Express units so they are functioning in that respect. What am I doing wrong or not doing? Do I need to set up a WDS? Is there a bridging mode? Do I need to have a relay? Surely internet via the Express is possible!

The Airport Express units are the A1088 variety. The Extreme is A1354. Originally I set up the base station to create a network and got the Expresses to 'join network'. However, since that didn't work, I dug a little deeper and investigated WDS and bridge settings. The base station wireless mode is 'Create a network'. I selected 'allow this network to be extended' and made sure that the channel used was the same as the Express units. I have set up one Express to be a WDS remote and one to be a WDS relay on the same channel of the same network with the same password. I have specified the MAC address of the base as the main and the other MAC addresses in the appropriate places for the Expresses. I have tried selecting the 802.11b/g radio mode manually as well as in automatic. Access control is off for all units. I have tried the base station connection setting on 'Off (bridge mode)' and 'share a public IP address'. Am I just missing something?

Firefox just started to do this if on one user account someone has firefox running another user account on the same computer can not connect to the internet through firefox while firefox is running in the first user account

Windows XP/Windows 7
2 user accounts on the computer. If each acct is logged into the computer and tries to have firefox running only one can connect to the internet at a time. Have Verizon FIOS for ISP and this just started to occur. Firefox version 8 but also happening in firefox 6.0.2. How can we run firefox in two computer accts at the same time? Thank you

I am having exactly the same problem. This worked on all versions of Firefox up until mid last week. It started failing on Wednesday, coincident with the installation of Firefox 8.0 (see attached gif showing the automatic update on that date).
To fix the problem, you have to shut down Firefox 8.0 on one account, switch to the other account and then you can run it there.
If Firefox 8.0 is running on on account, the other account will run Firefox, but when you enter an URL it waits for quite a while then reports "The connection was reset. The connection was reset while the page was loading".
We also use Thunderbird 8.0 and it does not exhibit this problem, and works at the same time as Firefox 8.0. I suspect they might share some components.
I'd be happy to supply more details if needed.
Thanks,
Ed

Why can't I access the internet from my ipad2

This problem started after the most recent update. Hotspot is on my iPhone4, carrier is Verizon. Did not have this problem before update. Do I need to restore iPad to original? What do you think?

When I try to open firefox, I get a message that says, "firefox is already running" and to close it or restart my computer when it is NOT running, so I can't get on the internet through firefox. What is wrong?

The information box pops up when I click on my desktop icon for firefox as well as if I try to access it in other ways. I have restarted my computer. I have tried removing firefox and redownloading it. No matter what I do, it still gives me a box saying it is already running, but not responding. When I pull up my taks bar, it is not running! I can't close it as the box suggests because it is not open to do it. I just keep getting a box saying it is already running no matter what I try to do, even though it is not running.

I have tried everything I could to fix this, but some things require actually being on Firefox, and since I cannot get on, I cannot click on the tabs to do it. I have even totally uninstalled firefox, and that has not fixed this. I still get the same message that firefox is running and I need to close it or restart (which I have also tried dozens of times). I have removed things like Java, and that has not helped either. If I cannot even get on line in firefox, how can I fix this. I am not crazy about using internet explorer, but right now, it is my only option. I even tried to start in safe mode, and the same message box pops up!

Every time I access the internet through Firefox I get a box with the message "Firefox could not download the search plugin ///c:/Users/Patton/AppData/Roaming/Mozilla/Firefox/Profiles/b2qcb69.default/extensions". How do I get rid of this thing? Thanks

How do I get rid of or fix this problem?

Thanks - I just deleted the ASK toolbar - don't use it anyway. It fixed the issue - thanks again.

You already said that
the answer us again
And again exactly are you doing? How are you trying to attach them? The basic answer is to use the media browser in the lower left hand corner of the attach window under Media ==> photos. ==> iPhoto

I can't access the internet with Firefox on my computer (Windows 7 PC). I have used Firefox as my browser for 1 year but 5 days ago it stopped working even though Internet Explorer worked fine. I can't solve the problem and need some help.Randy Brown

September 26, 2011
Dear Mozilla,
I am having some difficulty accessing the internet with Firefox on one of my PC computers. I normally use Mozilla Firefox as my web browser and google is my homepage and gmail is my email system. The operating system is Windows 7. For over a year this system worked perfectly but a few days ago it stopped working. When I launch Firefox now I get the message that that website (www.google.com) is unavailable. In fact, I can’t access any website and I am blocked from the internet entirely within Firefox. My internet connection is fine because Internet Explorer works fine. I can access google and any other website within that web browser. I have investigated all the security issue I can manage and found no smoking gun. I’ve tried uninstalling and reinstalling Firefox to no avail. Is Windows 7 compromising the effectiveness of Firefox? Any suggestions or other assistance you can offer would be appreciated.
Sincerely,
Randy Brown

Sounds like a bogus pop up. In any case power down your Mac, your modem, your router. Then power back up in 1 minute sequence; modem, router, Mac.

Why can't I access the updated that are pending on my phone?

Why can't I access the updated that are pending on my phone? I've turned the phone off and also closed all the apps. But still won't allow me to access the updates. Just a blank screen.

Another post is reporting that applying the 6.1 update fixes their issue. I'll have to wait until I am back on WiFi to try that.
