I have accidentally blocked Firefox's access to the internet, how do I unblock it?

Earlier I saw a popup while I was browsing that said that Firefox was trying to access my internet, and at the time this seemed suspicious. I don't know why, but I pressed "block" which, in return, blocked my entire access of the internet through Firefox. I tried reinstalling Firefox, and I also tried to do stuff with the firewall but I didn't understand what to do. How could I allow Firefox to access the internet again?

Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

I accidentally blocked Firefox from accessing the internet. I love Firefox please help

A box popped up and said a program was trying to access the internet and I hit block instead of allow and now I can't find the area where I can unblock programs.

You can always do without the other security features and choose to enable WPA encryption....that is the safest as of now.....
Simply set everything back to default and choose WPA PSK......type in an 8 digit WPA key then remember that....when you connect other clients to your network, they would need the same key....

WRT54G3G-AT Blocks only browser access to the Internet.

We have a WRTG54G3G router with Sierra Wireless AC881 card. Latest firmware, version 2.02.2. Good, steady AT&T signal. Works consistently when the Sierra card is directly in one of the three laptops we use. But, when using the router, many times one or more (but so far never all) of the laptops will lose browser connectivity. A change between IE or Mozilla gives the same result. Strangest part is that we can access http://192.168.1.1 but not the Internet beyond. If the problem crops up, we can put the laptop on a wired connection and often get through ---BUT -- after a while, the wired connection will stop as well. No amount of rebooting of any or all components helps. When a laptop is "locked out", it still has network connectivity. For example, I can ping www.yahoo.com and get packets back. Also, NSlookup resolves www.yahoo.com. It appears as if port 80 becomes blocked. The next day, a laptop that failed the night before will usually work fine. I have reviewed every setting in the router. There are no special rules or anything odd in the way we intend to use this router.

I have considered restoring factory defaults and starting over with the configuration. I think that's what you are suggesting? If so, instinct tells me not to restore from the image I have saved to disk. Instead, don't you think the best path is to hand configure it from notes? On the other hand, I don't agree with the "losing signal" theory as other laptops can still access whilst the one is not able to function. Additionally, a laptop that is locked out from the router can function just fine if I move the AirCard from the router to the laptop that has been locked out. Of course, that precludes the other workers from functioning... Thank you for the input, I'll give it a try. Allen

Firefox cut off access to the Internet.

Firefox cut off access to the Internet.
In a first time, Firefox completely cut the connection forcing me to restart the Mac OS 10.6.4.
I restored a version of Firefox antecedent using Time Machine than a month old.
Now, the connection problem is only partial and Firefox more accesses to the Internet.
In addition, I must force the software to quit and when I try to restart Firefox, a message tells me that "A copy of Firefox is already open. A single copy of Firefox can be open to both "...?? ?
You said weird? Someone has an idea on how to solve this?
Thank you in advance for your help.

After upgrading to the latest version of firefox. I can no longer access the internet and all traces of Mozilla Firefox are gone from my computer. I have no access to the internet, my home page or my e mails. What can be done??

I have been using firefox for years. I downloaded the latest version and at the conclusion of the down load I was refussed access to the internet. Something about Proxy???? I checked my firewalls and security and they said that mozilla was allowed but everytime I attempt to gain access I am refused. I cant access the internet and I cant download another program to access the internet. I uninstalled Firefox and attempted to reinstall but after uninstalling Firefox I have no means to reinstall because there are no traces of it on my computer and I no longer have access to the internet. What do I do? I cant access my e mails, stored messages, favorites etc etc.

No. After I select "Choose" the dialog box expands to provide only three choices. This is a new bug. I have only seen it in the past week or so, but it is maddening. I have observed that, while the Mozilla Foundation focuses on trivialities like which search engine should be the default, the Firefox application becomes buggier and buggier. Most of my family has switched to Chrome, and I will be following shortly. Firefox used to be a great program. Not any more. Getting assistance with a problem has also become very difficult.

Firefox will not access the internet. I have used Firefox for years and the past week I have not been able to get on the internet??? What is the problem. My interent works as I get email and can iuse Internet Explorer to access.

Is there a way to create a password for Firefox so Firefox is denied access to the internet without this password?

Is there a way to create a password for Firefox to deny Firefox access to the internet?

There is the Profile Password extension, but it is easily bypassed by using the Firefox SafeMode.

Another thing you can do is to set your Homepage to a website that you have a password logon saved for and use the Master Password feature. It won't completely stop someone else from using the internet but it will slow them down or make it appear they need a password for access.

i cant login anywhere as all my passwords are saved in firefox, i cant even access teh firefox preference to get my password, it's so sad

You likley have a corrupted Firefox preference or other support file in your User/Library folder.
Programs load these files from the user account to adjust to user specifications, instead of having multiple copies of the same program on the machine.
So when you reinstalled Firefox, it reinstalled the progrma only and the user support files remained from before.
To prove this point, use System Preferences to create another Admin account and log into it, Firefox should run like a charm.
To remove the Firefox support files from the problem user account your going to need to locate these files and delete them one at a time and try FF again and again.
The first one you shoull try is your FF .plist file located in your User/Library folder.
Clicm on the Finder and use the Go > Go to Folder and paste this
~/Library/Preferences
and press Go.
Now scroll down until you see the Firefox or Mozilla .plist file and Trash it, quit and restart Firefox, it will recreate the preference file with default settings you will have to reset it.
Next run through the list of fixes #1-13 here before proceeding.
https://discussions.apple.com/docs/DOC-3353
If you need help deleting other FF files, download the free Easy Find from MacUpdate.com and search for anything "Mozilla" or "Firefox" in your User account only and take your chances you hopefully won't delete your password file in the process.
You should have site passwords written down someplace and locked up tightin case you need them, a computer isn't totally safe and reliable.

I Have Accidentally Put My System Folder In The Trash...

Hello,
One day i was cleaning up my harddrive when i think i may have accidentally dragged my system folder to the trash can. At which point i shut down the computer. Now i went to restart the computer and a panic screen pops up and i cannot load into my os. i already tried force loading the start up cd and that don't work. i heard there is a fix for this i can't find it though. is there a way to fix this? Im ok with losing my data I would actually prefer to lose it.
Help Much Appreciated,
Hunt The Mac!
(Ibook G4 (10.4.11) PPC)
Just To Let You Aware I Have Other Computers If That Helps

What other computers do you have? If you have another Mac with FireWire, you could try starting up in FireWire Target Disk Mode with the iBook G4 as the target disk. This will mount the iBook's hard drive on the other Mac and you should be able to access the iBook's hard disk from the other Mac and drag the System Folder out of the Trash and back to where it belongs.

After a recent comcast / xfinity update I have been unable to even connect to the internet using firefox. I can using internet explorer.

After a recent comcast / xfinity update I have been unable to even connect to the internet using firefox. I can using internet explorer.

Take each of the following steps that you haven't already tried, until the problem is resolved.
Step 1
Restart the router. Many problems are solved that way.
Step 2
Change the name of the wireless network, if applicable, to eliminate any characters other than letters and digits. You do that on your router via its web page, if it's not an Apple device, or via AirPort Utility, if it is an Apple device.
Step 3
Run the Network Diagnostics assistant.
Step 4
Back up all data.
Launch the Keychain Access application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
Enter the name of your wireless network in the search box. You should have one or more "AirPort network password" items with that name. Make a note of the name and password, then delete all the items. Quit Keychain Access. Turn Wi-Fi off and then back on. Reconnect to the network.
Step 5
You may need to change other settings on the router. See the guidelines linked below:
Recommended settings for Wi-Fi routers and access points
Potential sources of interference
Step 6
Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
Step 7
Reset the System Management Controller (SMC).

Can Firefox ask for a password to allow access to the internet?

I need to control access to the internet in this workplace and require a password for access. Does Firefox have any way of doing that?

No it doesn't.

How to connect my Macbook with an ipad mini in order to have an access to the internet on my iPad?

Dear fellows, I am having a trouble in how to connect my mac with an iPad mini in order to have an access to the internet.

If you are attempting to share your iPad mini's cellular data connection with the MacBook, please check out the following Apple Support article for additional details on how to do so.

HT4410 I have just installed Windows 7 64-bit full version Home Premium using Bootcamp and cannot get access to the internet. I installed on a Macbook Air Mid 2012 with Mountain Lion. Are there some drivers that are missing from the Windows 7

Dear Apple. I have just installed Windows 7 64-bit full version Home Premium using Bootcamp and cannot get access to the internet. I installed on a Macbook Air Mid 2012 with Mountain Lion. Are there some drivers that are missing from the Windows 7 bootcamp install download from Apple

It is a Total Misconception that the Support files are installed when you are installing Windows, even if the USB drive that holds them is inserted in the system when doing the Windows install.
You must always Run the Setup.exe files from the support files or run the drivers individually once Windows has finished installing and booted to the desktop.
Also you really need to run the Boot Camp Control Panel Applet and check for updates as not all the newest drivers for full function of all the hardware is included with the original support download. That download is basically a generic version to get the system working and without doing the updates not everything will work properly.

I have frequent blocking on my imac with the little sphere spinning

I have frequent blocking on my Imac with the little spere spinning and some how as I've installed Mackeeper eveything seems to be allright so I don't understand what's going on Please can you help me

Mackeeper is a horrible preoduct. Get rid of it immediately. It's hard to troubleshoot anything else with MacKeeper in the way.

Can you also clarify what version of the Mac OS you have? "10.0.0" as shown in your profile will not run on a 2008 iMac. Doing "About this Mac" from your Apple menu will show your actual version, as in this example:
The OS version is indicated by the upper red arrow I added.
