Until very recently I used to be able to open multiple browsing windows in Firefox, but now I can only open one window & if I close down the session & try to reopen Firefox it doesn't open

I can restart Firefox only after rebooting my laptop.

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes). 
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]] 
 
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. 
You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions. 
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

Your MacBook Pro would be able to run Lion (which is required for iCloud). It's a $29.99 (US) upgrade in the Mac App store. Otherwise you can check your process for importing to iPhoto against this article: http://support.apple.com/kb/HT4083. A third option is to transfer you photos to your computer wirelessly using an app like PhotoSync.

MAC Mail: I have 2 accounts set up. I used to be able to add attachments to both accounts, but now I can only attach using 1 of the accounts. The other one doesn't work.

Try unmounting the volume on your iMac using Disk Utility. Then mount it again. You may need to reboot the laptop or relaunch its Finder process (using the Force Quit window) after remounting the drive on your iMac. Remember that no process may be accessing any files on the drive you plan to unmount, or the unmount will fail. Unmounting and remounting an external drive on my iMac made it become visible on my MacBook Pro after it had disappeared.

I can't seem to get my iPod touch (4th Gen) to play photo slideshows or videos through my TV. Is this a design flaw? Or is it me? My old iPod used to do it no problem, but now I can't even find any video out options in the settings.

IMovie was removed from my macbook pro after I downloaded OS X Yosemite, I had it before and have used it, but now I can only get it through the app store

iMovie was removed from my macbook pro after I downloaded OS X Yosemite, I had it before and have used it, but now I can only get it through the app store. I can't pay for it so I would really appreciate the help.

Look in your applications folder for the installer - Install OS X Yosemite. Delete it. Then go back to the App Store purchases tab and see if you can download it. You might have to re-index Spotlight.

I have an old and new mac and used transfer manager to put the old mac on the new so that i have both users on one computer but now I can only log in as the new and as guest so cant access my old computer docs on this newer mac. Help!

Hello I have just sold my old macbook and so transfered all my data to my newer macbook using transfer manager. This allowed my to login on the newer computer under either the old or new username so I could access both computers' data on my newer computer. Last night that worked but today I can only access my newer user and a guest user. Where did my old user name and all the data go after the transfer? Help please! I have to give the buyer the old computer today!
Aminah

I am not familiar with "transfer manager." Did you perhaps use the Migration Assistant? What operating system is installed on your new computer?
If you look in your hard drive, in the Users folder, do you see a folder with the name from your user on your old computer?
Best of luck.

Used to be able to import from Panasonic NV-GS120(DV), but now can't

Hi,
I have been able to import from our Panasonic NV-GS120 (DV) camera numerous times before using Imovie. However, now Imovie detects the camera, but when I go to push the "play" button to start the import process, the computer hangs. I have no idea as to why all of a sudden it doesn't want to work!
Any help would be greatly appreciated.
Thanks

Hi
Test another FW-Cable.
Test Your Camera on another Mac so that DV-in still works OK
Toogle in iMovie pref: Play-back via Camera (on<->off some times)
Other ways to import Your miniDV tape:
Use another Camera. There where tape play-back stations from SONY
but they costed about 2-4 times a normal miniDV Camera.
If Your Camera works on another Mac. Make an iMovie movie project here and move it
over to Your Mac via an external hard disk.
(HAS TO BE Mac OS Exchange formatted - USB/DOS/FAT32/Mac OS Exchange WILL NOT DO)
(Should be a FireWire one - USB/USB2 performs badly)
FireWire - Sure not using the accompany USB-Cable but bought a 4-pin to 6-pin FW one ?
Using WHAT ? :
• Mac OS - X.5.4 ?
• QuickTime version ? (This is the heart in both iMovie and FinalCut)
• iMovie 8 (7.1.?) ?
Free space on internal (start-up) hard disk ? (Others don't count)
Does Your Camera work on another Mac ?
Sorry to say it is to easy to turn the 6-pin end of the FW-cable 180 deg wrong.
This is lethal to the A/D-chip in the Camera = needs an expensive repair.
(Hard to find out - else than import/export to another Mac ceased to work
everything else is OK eg recording and playback to TV)
Delete iMovie pref file may help sometimes. I rather start a new account, log into
this and have a re-try.
from LKN 1935:
Hi Bengt W, I tried it all, but nothing worked. Your answer has been helpfull insofar as all the different trials led to the conclusion that there was something wrong with my iMovie software. I therefore threw everything away and reinstalled iMovie from the HD. After that the exportation of DV videos (there has not been any problem with HDV videos) to my Sony camcorders worked properly as it did before. Thank you. LKN 1935
from Karsten:
in addition to Bengt's excellent '9 yards of advice' ..
camera set to 'Play' , not rec/computer/etc.?
camera not on battery, but power-line?
did your Mac 'recognize' this camera before...?
a technical check:
connect camera, on, playback, fw-connected...
click on the Blue Apple, upper left of your screen ..
choose 'About../More..
under Firewire.. what do you read..?
Yours Bengt W

HT4059 I used to be able to transfer PDFs from Dropbox to iBooks but now the file appears for about 1 second and then disappears - any ideas?

Can anyone help? I want to transfer PDF files from Dropbox to iBooks but when I do, the file appears for about 1 second then disappears. I used to Beatle to do this with no problems, but now it doesn't work. Help!

I had the same problem. After numerous attemps to Restore from Itunes, I decided to use the "Setup as New Ipad" option. It went through a few question on new setups. Afterwards all my apps, data, photo's were still intact. Which shows that the Restore from Itunes worked. There must be a small bug that prevents the Ipad to open after "Restore from Itunes" . Hope it will help you.

I used to be able to print to my printer from iPad but now I cant

1. Turn the router, iPad and printer off.
2. Turn on the router and then wait 30 seconds to let it complete its start-up process.
3. Turn on printer and then wait 30 seconds to let it complete its start-up process.

My iPod won't charge on a wall charger, only on the computer. I used the same cord for both though. I used to be able to charge it with a wall charger, but now suddenly I can't. I've even used other wall pieces. Nothing seems to work.

My iPod will no longer charge with a wall charger, only the computer. I know it's not becuase of the wall piece or my cord, since I also use the same cord for computer charging, and the wall piece seems to work with others devices. It worked a couple of weeks ago, then suddenly quit. I think it may be something to do with the inside of my iPod where the charger goes. I find it really inconvient to always have to use the computer to charge my iPod. I believe I have a three year warrenty on my iPod, but I wouldn't think it would cover this problem. Is there anything I can do to fix it?

Not Charge
- See:
iPod touch: Hardware troubleshooting
iPhone and iPod touch: Charging the battery
- Try another cable.
- Try another charging source
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
- Make an appointment at the Genius Bar of an Apple store. Bring the wall charger
Apple Retail Store - Genius Bar
If you have a three-year warrany it is not from Apple. The standare Apple warrantyis 1 year and y can purchas an extended warranty that give y a total of two years. You can check your Apple warranty coverage hee:

I was able to print wirelessly from my 4S phone but now I can't. Where on my phone can I check its printing cababilities?

I can print sometimes from the HP 1100 printer but then I can't. The printer is printing the macbook documents wirelessly so it must be my phone. I can't find any information on my phone about its connectivity to printers.

Can be a bit convoluted as the phone doesn't actually have any drivers in the tradtional sense.
What it does is locates WiFi printers on the same network and connects over an adhoc connection.
The pint job is sent as an e-mail over the Wifi connection and the printer converts that e-mail PDF and sends that as a local print.
The point of break down is usually the Wifi connection and it may be necessary to reboot the printer to gain a stable link.
Also make sure your phone is actually connected to the Wifi network and not just the mobile network !
There are other print solutions you might want to try however these need a Mac/PC host machine.
On the Mac Pintopia adds the ability to print via the host to just about any USB connected printer and is imo more stable than airprint.the host must be running for this to work.
You can also try an app called We Print server that works on PC and Mac hosts and allows printing via the 3G network as well as local Wifi. Its very useful.
Finally you can make some adjustments and view the print job on the iOS device by starting a print then double clicking on the home button in the task bar you will see a new icon called Print Center where you can make minor adjustments and even cancel the job if you want,

I used to be able to have two ways to secondary click in 10.6. Now I can only pick one in System Preferences/Trackpad.

Is there any way I can have secondary click activated by two fingered tap on trackpad AND by clicking the bottom right of the trackpad?
I have a Macbook, Late 2008

They've consolidated the options as you see. You can still two fingered tap and click but you need to use two fingers to click. You can do this anywhere on the trackpad.

I used to have icons for my two printers in my dock. Now there are only question marks. How do I get the icons back?

How do I get my printer icons back on my dock? I went to System Preferences and tried to drag the pix of the printer to the dock. Would not work. No icon in Applications to use.

I just tried something. I printed a page from my printer; printer icon showed up in dock. I quickly right clicked on the icon and selected Options/Keep in Dock. Now my icons are back.
