When I am playing scrabble I WANT to be able to go to Dictionary and two letter words. These are being blocked. How do I get them to stop blocking?????

AGAIN! When I am playing scrabble I want to be able to go to Dictionary and Two Letter words when I am playing the game - these are being blocked much to my aggravation! How do I stop the blocking?

Hmm, what site is this game on?
Is the Dictionary part of the same page, or a separate page/add-on in Firefox, or a completely separate program?

Log-in pages are being blocked.

All the log-in pages to my regularly visited websites are being blocked. Saved sites that have stored log-in info or sites where I have accounts that I need to sign-in to access all get the same error - "This Connection is Untrusted. You have asked Firefox to connect securely to (insert website url here), but we can't confirm that your connection is secure. Blah, blah, blah."
Anyone know what's causing this and how to fix it?? I have decent anti-virus software and I did a complete scan, came up clean.

*Check the permissions for the domain in the current tab in "Tools > Page Info > Permissions"
*Check that images are enabled: Tools > Options > Content: [X] Load images automatically
*Check the exceptions in "Tools > Options > Content: Load Images > Exceptions"
*Check the "Tools > Page Info > Media" tab for blocked images (scroll through all the images with the cursor Down key).
If an image in the list is grayed and there is a check-mark in the box "Block Images from..." then remove that mark to unblock the images from that domain.
There are also extensions (Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images.

Updates are being installed by system administrator - stuck!?

Snow Leopard Server seems stuck on this process and indeed I am now scared to reboot!
I have logged on as a diradmin and the updates are visible in the Software updates and despite my clicking install, it does not and seens hung at this process and then if I log out and attempt to apply "software Update" via the Apple menu it tells me that it cant as "Updates are being installed by the system administrator"...
Its a catch 22, closed loop of some sort!
thanks

The links in my emails are being blocked. How can I fix this problem?

The links in my emails are being blocked!

It could be that the your work router/network is blocking those sites. Some work networks do block some sites.
You can also try another browser like the Chrome browser available from the App store.

Ports are being block (not responding)

Ports are being block (not responding), port forwarding is configured on the router and firewall is turned off on the server (osx 10.8). Am I missing anything?
Server has a static IP which I forwarded to ports to
I'm setting up VPN server and need ports 500, 1701, 1723, 4500 open
Thanks

Depending on the exact set-up of the network, L2TP requires UDP ports 500, 1701 and 4500 and the IP-ESP protocol, which is IP protocol 50; ESP.
Other than ESP (which is protocol 50 and not port 50), these are UDP ports, and not TCP.
TCP 1723 is used for PPTP. Not L2TP.
It is common for L2TP passthrough to fail when more than one connection is active.
As compared with L2TP, PPTP is usually easier to get going around NAT. Though conversely, L2TP is rather more secure than PPTP.
Check your Mac OS X Server firewall settings, too. If you have some outboard network device providing a NAT gateway, try dropping the server firewall.
Use of an external firewall-gateway with an embedded VPN server is something I've variously recommended, too. (I find that VPN NAT passthrough is something best avoided, as VPNs and NAT are operating at crossed purposes. VPNs seek to keep connection end-points known, while NAT tries to hide those connection end-points. Doing the VPN processing on the Internet side of the NAT is just... well, easier.)
Also ensure that your ISP is not blocking VPN connections. While you might be on static IP, confirm the ports are open. Trust, but verify. Get yourself a UDP port scanner, and have a look.
If it's permissible within your ISP service tier (and depending on what protocols you're testing), probe the specific target ports using telnet or the openssl s_client command and (particularly for this case) the nc (netcat) tools, and see if the ports allow access. nc can run port probes on UDP, which is the key piece here given telnet and s_client target TCP and TCP SSL connections. Probably something like the nc -zu w.x.y.z udp-port command.

Incoming calls are being blocked

Some of my incoming calls are being blocked and when I try to answer them they go to voicemail. I can't seem to find a reason for this and I have not found a way to stop this from happening. Sorry I have a iPhone4 with the latest software and firmware.
Thank you

Either the tower you are connected to has no channels available, the MTSO it connects to is overloaded, or you have 3G turned off or it isn't available where you are located. While 3G supports simultaneous voice and data EDGE does not, and data takes precedence. So if you are using data at the time someone calls you the call will be diverted to voicemail.

Email messages I want to receive are being blocked as spam

Email messages I want to receive are being blocked as spam. What can I do to rectify this?

Spam is related to email / webmail. If that is your problem ...
Firefox doesn't do email, it's strictly a web browser.
If you are using Firefox to access your mail, you are using "web-mail". You need to seek support from your service provider or a forum for that service.
If your problem is with Mozilla Thunderbird, let us know and we can move this thread to the Thunderbird queue. This question currently is in the Firefox queue for answers.

Messages to Verizon recipients are being blocked

Messages to Verizon recipients are being blocked by the anti-spam system. I submitted whitelist requests several times, but just get automated messages in return saying the IP is dynamically assigned. It's not. No spam is going out from the system, and SPF, PTR records are correct. We are not on any of the blacklists (checked with all known RBLs) and have a very good reputation on senderbase.org.
Can someone please help and assign an agent to help us in this matter?
We have many nonprofit organizations and several doctors who can't reach their visitors.
I personally have a Verizon account and all my emails to Verizon are getting blocked when I sent them out using our mail server.
The mail server in question is: {edited for privacy}
Blocked IP address: {edited for privacy}
Any help appreciated.
Solved!

My call from Skype to landline phones are being blocked

I live overseas and the easiest way to make calls to the US is by using Skype. Recently, however, my Skype calls are being blocked as unsolicited calls by landlines. Of course, the instructions given by the recorded message, do not work (*82 followed by the number). How can I start getting my calls to go through to those who block unsolicited calls? -M

I am facing the same problem...When dialing from Windows PC, there is not even a ringing tone. But from Android phones, it gives rining tone only for me and the receiving side actually doesn't receive call itself. I am living in Dubai..Please suggest a soultion for us.

Google and all of its related services are not showing as a secure and pictures are being blocked.

I was forced to add manual exception to even use Google search AND Google email but pictures are still being blocked in Google search. The first 12 pictures will show but the rest only reflect a broken square in the top left corner of where the image preview should be. When I click on the blanks- it shows the picture but I can't work efficiently that way. How do I remove the block on images until the issue can be corrected in another update?
Google Chrome was doing the same thing (blocking images from trusted MAJOR sites like Facebook and Twitter but considering its own material secure). Chrome did not allow a user to control if the images could show and I switched to Firefox as a result. Please fix this. Thanks!

All I had to do was update my clock time and it fixed the issue. My clock was showing December 6, 2014 as the date. Sorry. You can consider this resolved, Thank you!

My calls are being blocked from calling our office.

I haven't been able to make calls to any of our office (various locations) phone numbers using my AT&T cell phone for the last 3 days. My phone works fine otherwise - I can call everywhere else. Why are the calls being blocked? The office uses Integra Telecom. Apparently NO AT&T cell phone calls are going through. There is no problem with any other carriers, just AT&T.

Hello @susankip
I’m sorry you’re not able to dial out to your office.
It sounds like there is definitely a routing or dialing pattern issue going on.
To better assist with this, please contact us as soon as possible.
You are welcome to use our live chat option as well.
Thank you,

I updated my account and now emails with photo attachments are being blocked

On Sunday I received something from y'all asking me to update and I did.
Now when I go to, say, Google, there is a little green icon besidethe word saying that y'all have checked it and it is safe.
More critical. my friend has tried to send photos to me every day since Sunday and they keep getting kicked back. Her inbox has been bombarded with messages that says I didn't ask for anything from her and that I am not accepting her email

Please restart the computer and try again.

Email images via Comcast are being blocked yet under "Contents" all images are allowed. How to correct?

Email images via Comcast are not being loaded. Comcast says its not them, that its Firefox. Under Tools Contents All Images Loading is checked. What Firefox setting(s) do I need to do to get my email images to load. They used to until a couple of weeks ago.

All I had to do was update my clock time and it fixed the issue. My clock was showing December 6, 2014 as the date. Sorry. You can consider this resolved, Thank you!

Suddenly I am unable to send emails, which are being blocked due to "suspicious activity." Yahoo help notes it is probably my ISP that is preventing my emails from being sent. How can I unblock this?

On Friday afternoon, I attempted to reply to emails in my Yahoo Inbox, but I received a pop-up message preventing me from sending the emails. It said that my emails cannot be sent due to suspected "suspicious activity" on my email account and cannot send it in order to protect me and those I am attempting to send the messages to. I looked up Yahoo Help and the online suggestion was that my ISP might be blocking the email and I might have to change my ISP address. My antivirus software carrier's server went down briefly a couple of weeks ago and I could not upload the updates until they were up and running again. I had some suspicious emails generated from my account during that time, without my knowledge. I changed my password immediately and updated my Email Protection through my antivirus software program. But now I can't send emails. Any suggestions? Thank you!
