Firefox doesn't load any page after a while.

I'm having problem with firefox while surfing after a while. For example at first 15 minutes , there is no problem , after a while firefox doesnt load any page , i have to close it and reopen it again to make it work. While firefox is not loading , i can use other browsers as normal. It just doesn't load any page at all but the program itself responds so I can close it with X button.What could be the problem , I'm using latest firefox.

The default of the pref network.http.max-connections has been increased from 30 to 256 in Firefox 6+ versions.
Try to decrease the value of the pref <b>network.http.max-connections</b> from 256 to 30 as used in Firefox 3 versions.

Photoshop CC doesn't load any pictures

Hi,
my Photoshop CC (up to date) doesn't load any pictures I want to open.
I tried any way to open a file but it did absolutely not work.
Please help me
Thanks a lot

The default Photoshop installation does include a LOT of presets in the application directory (in a folder named "Presets").
If that folder is missing, you may need to restore it from backup, or reinstall Photoshop.

ITunes doesn't open any more

My iTunes doesn't open any more all of a sudden, though Task Manager has listed it in "Processes". Quicktime and everything else works, though.
I've tried de-installing and re-installing serveral times.. Even older Versions (iTunes 10.5) won't work.
Can you tell me what to do?
Fyi: I'm using Windows 7 and iTunes version 10.7.
Thank you!

AirportExpress - AirTunes doesn't work any more after wifi router change

AirTunes doesn't work any more since I have changed my wifi router.
I have fully reseted the AirportExpress station. I can see the AEX station in the drop down menu of iTunes but it can't connect.
When I use Airfoil, all works fine.
I have tried to trash to Airport preference file but this was unsuccessful as well
Any idea to correct this ?

Try the following steps and let me know if this works for you.
Press the wireless button on your printer, go to print reports, and select configuration.
After you have that, we will need to access the printers Embedded Web Server (EWS). You can do so by entering the printers IP address (from the network configuration page) into your browsers address bar and pressing enter.
Once there, press the "Network" tab at the top of the page. From there you will want to click the "IPv4" button, located on the lef-hand side of the page. It will be there for WIreless and Wired, so make sure to click the one for you however you are connected. If you do not see "IPv4", you should see "Networking", press that and then press "Network Address(IP)".
Next, you will want to click the small round button next to "Manual IP Address" and then fill in the boxes for IP Address, Subnet Mask, and Default Gateway, using the information found on the network configuration page.
For the Primary or Preffered DNS Server, you will want to enter 8.8.8.8.
For the Secondary or Alternate DNS Server, you will want to enter 8.8.4.4.
Click apply and when the message pops up saying that the changes have been applied, press "OK".
Press the power button on your printer, wait for it to fully power off and then press it again to power it back on.
After doing this, go ahead and try to enable ePrint again.

Mini displayport doesn't work any more

My Mini Displayport doesn't work any more with VGA, DVi, just with the Apple Cinema Display. It started one week ago, I've tried many different monitors, but it seems to be that it only works with the Apple Cinema Display, Thunderbolt Ethernet Adapter is also accepted but nothing else. PRAM, SMC, booting from an Harddisk with Mavericks (I'm on 10.10.2), Safe Mode, nothing works. I have a Macbook Air, 11 " from Mid 2013, no warranty any more. Today I was at Bense, a german reseller (thank you guys for your effort), they did the same tests and some more, but also found nothing. Is there anyone with the same problems and a solution for it?
Cheers

Does it work on the other command key? I typically use the one to the left of the space bar, and at one point of time, it stopped working. but then i started to use the command key to the right of the keyboard which worked. but, then i started using the one that wasn't working, and just clicking slowly rather than quickly, and now it seems to work again. Don't know why . . . but that is what happened for me.

Safari 5.0.2 doesn't save any more google search results in the history.

Hello together,
Safari doesn't save any more google search results in the history.
Steps to reproduce:
1.) go to google.com
2.) search for "APPLE"
3.) open the history
Result: the search for "APPLE" is not saved - only the Google mainpage.
This has something to do with the new search string in the Location bar. Safari does not save URL with /#.
For example:
the new string is http://www.google.de/#hl=...
the old one is: http://www.google.de/search?hl=....
The change must something to do with the new Google-Search-Feature. When I deactivate it, then google works with the old string and I found the searches in the history.
The second negative effect is, when you type "apple" into the location bar (after a search), the autocomplete shows the search result, but when you hit enter, you are redirected to the Google-Mainpage.
Very annoying
Can somebody confirm.
Thanks

The program is totally useless. What the h%+l is wrong with adobe? At least I can still use Photoshop CC. Anyone got a fix for this?

Aperture 3.0.3 - MobileMe doesn't work any more

F*!
I have installed new Aperture update and since then I'm only having problems. First I had to repair my library. Fortunately worked.
But the sync of my MobileMe galleries doesn't work any more. I try to start the sync manually but it doesn't work. I double click on the sync icon but nothing happens. New galleries do not sync, too.
Aperture is really annoying. Every some weeks more trouble. Slow, not syncing, what will be next?
Did you have the problems with MobileMe and Aperture? Any idea what to do?
Thanks ...

Actually lost some photos in my galleries after the update. I held down the Option and Command keys while starting APerture and repaired the library permissions and then resynced the galleries. One gallery was stubborn, I had to remove a photo from this gallery and then drag it back into the gallery. This allowed everything to update.

In iTunes, how do I switch to an Ipod nano from and old ipod that doesn't work any more

in iTunes on your computer, how do I switch to an Ipod nano from and old ipod that doesn't work any more? It has all the folders and songs I had on my old ipod, but does not recognize my ipod nano and cannot sync with it?

Hi bob12345S,
If your iPod nano does not appear in iTunes when connected to your computer, you may want to troubleshoot using the steps on this page -

Thanks for using Apple Support Communities.
