I am running Firefox v28. When I open firefox, I get the toolbar and I can even open preferences window but that all! No browser windows (or even help pages).

I use a Macbook pro 13" version 10.9.1. I have tried the obvious fixes ie turning pc off and on. Chrome and Safari run fine so no network issues. I followed the advice to turn Proxy setting off but this made no difference. Really dont know what to do so help appreciated. (the links below - to install the 'trouble shooting' or the 'educated guess' about my system does not open.

Hello Lozzer62,
Thanks for contacting Mozilla Support. The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. <br>
'''Note''': ''This will cause you to lose any Extensions and some Preferences.''
*Open websites will not be saved in Firefox versions lower than 25.
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
Did this fix your problems? Please report back to us!
Cheers,
Patrick

When trying to open iphoto I get the error message "You can't open the application iPhoto because it may be damaged or incomplete." How do I fix this and get my photo's back?

When trying to open iphoto I get the error message "You can't open the application iPhoto because it may be damaged or incomplete." How do I fix this and get my photo's back?

To re-install iPhoto
1. Put the iPhoto.app in the trash (Drag it from your Applications Folder to the trash)
2a: On 10.5: Go to HD/Library/Receipts and remove any pkg file there with iPhoto in the name.
2b: On 10.6: Those receipts may be found as follows: In the Finder use the Go menu and select Go To Folder. In the resulting window type
/var/db/receipts/
2c: on 10.7 they're at
/private/var/db/receipts
A Finder Window will open at that location and you can remove the iPhoto pkg files.
3. Re-install.
If you purchased an iLife Disk, then iPhoto is on it.
If iPhoto was installed on your Mac when you go it then it’s on the System Restore disks that came with your Mac. Insert the first one and opt to ‘Install Bundled Applications Only.
If you purchased it on the App Store you can find it in your Purchases List.

I recently downloaded a program ScanFont 5, When I try to open the installer I get the following message: "You can't open the application "(null)" because it may be damaged or incomplete. Is there any way I can get the installer to open anyway?

I recently downloaded a program ScanFont 5, When I try to open the installer I get the following message: "You can't open the application "(null)" because it may be damaged or incomplete. Is there any way I can get the installer to open anyway?

The message means just what it says. Remove the damaged copy and try downloading it again.
Edit: Looking at FontLab's page, there's two issues going on.
1) It's a PowerPC app and will not run on any version of OS X newer than Snow Leopard, 10.6.x.
2) The "workaround" they offer is to purchase the Windows version and then run it in the the open source Wine, Windows emulator.

I keep getting the error message: " You can't open the application "%@" because it may be damage or incomplete" when I try to install a software that I purchased.

I have a typing software that I bought a while ago. I had installed it on an old pc but I just bought a macbook and I'd like to install it onto the new macbook, as I no longer use the old pc. When I open the installer, I get the error message: " You can't open the application "%@" because it may be damage or incomplete"
Does anybody know if this is fixable or if I need to just buy a new disk?
Thanks!!!

I copy pasted this from the developers website for the minimum requirements of your device: Macintosh® OS X 10.4 – 10.5, PowerPC G4, G5 or Intel Core Duo processor, 800 MHz processor or higher, 256 MB RAM, CD/DVD-ROM drive, 300 MB free hard disk space, Video card with 32 MB of video RAM, 1024 x 768 24-bit color display, Speakers, keyboard & mouse.
Does a macbook pro meet these requirements?

When I try to open downloads a new tab appears at the top of the screen and I can't open it.

I am currently unable to access any of the downloads I have. I just see a new tab at the top and I can't open it.

Can you attach a screenshot?

On my ipad mini, when I delete an email from the inbox (and it goes into Trash), it immediately deletes that email from the server (ATT/Yahoo). I've called support for both ATT and Apple and can't find a way to have the emails remain on the server.

My husband and I share an email address and if he misses a day checking email on his notebook, he doesn't receive the items that I have sent to Trash on my iPad Mini.
Appreciate suggestions.
[The curious thing is, if I "move" the deleted emails from Trash on my iPad Mini into the Inbox, I can go to my notebook, open my online email and they are back in my ATT/Yahoo Inbox.]

I have a pdf that will only open in Adobe Reader. I need to print it but when I try, I keep getting the message "Before you can preform .....you must install a printer." I have several printers networked to this machine. They all have up to date drivers. I've tried changed the default printer. I must print this document and am getting very frustrated. I am on a Windows 7 PC.

I installed a new hard drive and trying to reinstall FCP2 and on the install disc i get the following message - "You can't open the application FC Studio.mpkg because power PC applications are no longer supported"

Because you are running lion.. FCS 6 is a Power PC app and Lion doesn't support Power PC anymore.. So you can't install it.. Three options..
1. Revert back to Snow Leopard.
2. Purchase FCP X...
if you can't stand FCP X
3. Call apple directly, 1800-MYAPPLE and ask to purachse FCS 3 for $999... (its FCP 7)
I just got FCS 3 today through apple phone sales..

First, quit "Dropbox" and see whether there's an improvement.
Finder crashes are often caused by "Google Drive." If it's installed, I suggest you first check for an update. If that doesn't solve the problem, remove it according to the developer's instructions. You may need to start the computer in safe mode to do so. Back up all data before making any changes.
If you use Google Drive and don't want to remove it, then try deselecting the option in its preferences to "show status icons." According to reports, that may be enough to stop the crashing.
Similar cloud-data clients such as "Dolly Drive," "iDrive," "Open Drive," "Transporter Desktop," and others can cause the same problem.

Why is firefox sliding to the right and I can not open the window?

I have a status bar at the bottom...no problem. The problem is that when I open Firefox I see the icon for several windows opened over lapping and I can not get one of them to maximize for me. They, very quickly, slide to the right and off the screen. I ramdomly slide my mouse, somewhere off the screen and can drag a very vague window back, but it will not stay and slides to the right again. This does not happen with IE.

If still problem try the remaining items of:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
