Firefox unable to connect after update!

I performed the Firefox upgrade to 4.0.1 today and now Firefox and IE8 won't connect to internet. Safari is able to connect as well as 2 other computers so I know the internet is working. Also IM programs work pointing to the internet working.
I tried removing Firefox and IE still wouldn't connect, I then tried to reinstall to Firefox 3.6.17 and it completed, but it won't open.

A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.
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.

Unable to connect after update

Dear all
maybe it is the same issue, but since the latest updates I am receiving this message:
Unable to connect to remote PC. Please verify Remote Desktop is enabled, the remote PC is turned on and available on the network, and then try again.
Anyone an idea how to tackle this?
Thanks!

I am getting this same error after the update. I can use RDP from a windows machine to remote in to my work PC but the RDP on the mac just gets this error

One very useful defense against War Drivers is to hide your network...
You are fooling yourself if you believe that. Even if this option is enabled, the network name is still broadcast between the base station and any connected clients. It only takes a second to discover the "hidden" network name. You would expect "War Drivers" to know this.
The SSID is broadcast in clear initially between the client and the access point when setting up the connection. Once a secure assocation is made, it is then encypted.
If a War Driver wants to park and sniff for long periods in the hopes that they will pick up the initial contact, there is not much you can do. In the meantime, setting up a closed network is still one line of defence against unauthorised access to your WiFi network.
Of course if no encryption is used, the SSID is in the clear in all packets but still needs to be sniffed to be revealed.

Unable to connect after update to 8.0.13

Hi, I've been using the previous version for some time without any issues. Since I updated to 8.0.13 I can't connect to my remote machine anymore.
I'm using Yosemite 10.10.2.
The remote machine is behind a TS gateway.
When connecting, the app shows a black screen with "Negotiating credentials..." and never leaves that screen.
With a lot of effort I was able to find and download an older version (8.0.7), which works perfectly.
Please test your updates before submitting them to the AppStore.

Hi, I am having the same problem.... I need to downgrade ASAP.
Can you help me finding an older version of Remote Despot Client for MAC?
Sure, here is a link to 8.0.7 dmg:

Unable to connect after update to ios 5

I have recently updated my ipod touch 2nd generation to ios 5. when im connecting to my home network, it finds it ok then all i get is the little spinner next to it. ive checked my iphone and this shows up as a tick and is working fine. everything else on the network is also working fine. i do get the bars showing up on the wifi connection but when i try to go on safari, mail or apps it says theres no internet connection.
ive tried all of the main points ive seen in the forums. Powering off, resets etc. but nothing changes.
any help would be greatly appreciated.

Have you powered off and then back on your router?
Does the iPod successfully connect to other networks?
When you go to network properties what IP addres, gateway and DNS server is listed?
Have you tried here:

iPhone 3GS, iOS 6

Your iPhone was "unofficially" unlocked by some means to work with a different carrier. Now that you have updated it has relocked to the original carrier. If you do not know who the original carrier was you will need to call AppleCare and give them the model and serial number of your iPhone. Then you will need to contact that carrier to see if they have a process to unlock the phone and if you qualify.

this still didn't fix iPad connectivity after updating to iOS 6.0.1 !!! intermittent wi-fi connection, even with a direct line-of-sight to the router.

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Unable to activate after updating to iOS 6

The iphone 3GS is unable to activate after updating to iOS 6 i'm connecting it to iTunes but it says there is no SIM card which there is plz help

connect phone to iTunes, click OK on any of the error boxes that come up. Then with your iphone still connected to iTunes, hold down the home button and press the lock button and count to ten, then let your finger off the lock button whilst keeping your other finger on the home button for a further 10 seconds. Your phone will then go into restore mode, a message should then pop up on iTunes asking if you want to restore and update - click yes. I followed the procedures and my phone is now running perfect with ios 6.0.

Firefox would not connect after upgrade. Did system restore (XP) and not firefox wont even start

Firefox would not connect after upgrade from verion 6 to version 7. Did system restore (XP) and now firefox wont even start

Sometimes Firefox will hang during startup or shutdown, and still be running invisibly in the background. Usually in that case, you need to "kill" it either by restarting Windows or using the Windows Task Manager. It sounds as though you are familiar with opening the Processes tab, finding firefox.exe, and using End Process.
If you use an advanced firewall or other security software that tracks which programs are permitted to use the internet, please see these articles:
* [[Fix problems connecting to websites after updating Firefox]]
* [[Configure firewalls so that Firefox can access the Internet]]
A couple of other suggestions:
(1) Can you start Firefox in its Safe Mode? Hold down the Shift key when starting Firefox. You should get a two-button dialog. Click "Start in Safe Mode" (''not'' Reset). Any difference?
(2) In case your regular software missed something that is interfering with Firefox, try the scanning and clean-up tools listed in this article: [[Troubleshoot Firefox issues caused by malware]]

Both iPod and iPad won't connect after update. iTunes says "can't allocate a resource"

I had the same problem after updating to iOS 7 today. I did follow the advice on another site, but additionally rebooted my iMac. Worked after that.
Follow these steps to reset the Lockdown folder:
Disconnect all iOS devices from your computer and quit iTunes.
From the Finder, choose Go > Go to folder.
Type the following and then press Return:
/var/db/lockdown.
The Finder window should display one or more files with long alphanumeric file names.
In the Finder, choose Edit > Select all. Then, choose File > Move to Trash. Enter an administrator password if prompted.
Note: Do not delete the Lockdown folder itself. Delete only the files contained inside the Lockdown folder.
Reconnect your iOS device and open iTunes
My Additional step: reboot the Mac. Your iPad should give the first indication that it has worked by asking you to "trust this computer" or some such. Agree. Then iTunes should have reopened with your iPad showing and syncing.
