I trashed my mimetypes.rdf file to reset download actions, and now Firefox won't open because profile missing, please advise

Up until recently, when I would download a pdf file, it would automatically open, and recently, for some reason, it stopped opening automatically and just downloaded to my desktop where I wanted it. I found instructions on Mozilla if files downloaded but not displayed, that included displaying my profile folder and then deleting it. I trashed it (different from deleting?) and now if I try to open Firefox, I get the message that Firefox can't open/load because profile is missing. Please advise how I can get the profile folder back in.
thanks

Create a new profile as a test to check if your current profile is causing the problems.
See "Creating a profile":
*https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
*http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.

I followed your help directions on "Corrupt extension files" under "Unable to install add-ons", foolishly deleting the files you told me to. Now firefox won't open. I tried reinstalling firefox but it still won't open. Now what do I do?

I was trying to install the SEOQuake add on. After clicking install Firefox would hang up saying the script had timed out and asking if I want to stop it or continue. Didn't matter which option I chose nothing would happen. The only way to stop it was to close Firefox and restart. Tried restarting the computer. Still wouldn't install. Tried installing the Outwit add on and got the same error leading me to conclude it was a problem with Firefox, not the add on. I found this help page <http://support.mozilla.com/en-US/kb/Unable+to+install+add-ons?s=addons+won't+install&as=s> and did everything it told me to. Finally at the end I got to "Corrupt extension files". I foolishly deleted the files you told me to and now Firefox won't even start! I tried reinstalling Firefox and it still won't start. Tried restarting the computer. I have no idea how to get back to where I was let alone install the add ons I wanted to install. Please help. At this point I'd just be happy to be able to get Firefox working.

Accidentally dragged Excel to Trash and now it won't open.

I dragged Excel from Office 2008 to the Trash file. I then dragged it out and now it won't open. I have tried reloading the software but am stymied there as well by a message that the version I now have is newer than the version on my disc. Help.

Margaret make sure you backup your system using Time Machine and/or a bootable clone. After doing so then uninstall MS Office. You will find a uninstall routine in the MS Office folder located in Applications. After uninstalling MS Office then re-install using the original DVD.
BTW, going forward there is a forum specifically for Office for Mac hosted by Microsoft, click on Office for Mac Product Forums. I would recommend bookmarking the site.

ITunes 11 previously imported a video file, which I loaded on to my iPod Nano, but I removed the file from the iTunes library and now it won't (re-)import the same video. Any thoughts on why not?

iTunes 11 previously imported a video file, which I loaded on to my iPod Nano, but I removed the file from the iTunes library and now it won't (re-)import the same video.
I'm using 2 PCs, each with video files (.MP4) on their respective hard drives, and also one external drive with other video files on that I move between the two devices.
iTunes on one PC will (sometimes!) let me add video content from the external hard drive, which is clearly iTunes-compatible, because I can then copy it over to my iPod Nano. On the other PC, I couldn't load that same video from the external hard drive. But if I copied that same video on to the PC's internal hard drive first, then iTunes would let me import it. That was yesterday - now iTunes is refusing to load any files from the internal or external hard drive(s).
Any thoughts or suggestions, please?

So I tried copying the files from the external hard drive to a USB drive. I could import the video files from the USB drive!
So then I tried importing the same files on to my PC's internal hard drive again. I could import the video files from the internal hard drive!
So then I tried to import the very same files that failed to load on the very same PC previously. I could now import them!
I still can't import from the external hard drive directly, though.
I really don't think I like the process of importing things into iTunes very much... any suggestions on what's causing any of this behaviour would be very interesting.

I've stuck with Entourage way too long. Now I don't dare install the Mavericks OS because all my Entourage files will go away. And my iMac won't open Mac Mail (probably because I've never opened it in the 5 - 6 years I've owned the Mac.) Any suggestions?

If you are wondering why you are not getting any responses, it is because you have vented a complaint without any details that make any sense or give anyone something to work on.
If you want help, I suggest actually detailing what has happened, with versions of software etc. Anything that would let us assist.
As a start I am guessing that you have not really got the hang of "How it all works". Firstly download the Pages09_UserGuide.pdf from under the Help menu. Read that and view the Video Tutorials in the same place. A good addition would be the iWork 09 Missing manual book and something to help you learn how to use your Mac.
If there are specific tasks you need help with:

If prefs are the same as Settings on a MAC, OK, it would have been more
clear to me if you had said Settings since I didn't see anything related to
prefs. On a PC, I know what you mean, On a MAC, wasn't sure.

i just reseted my ipod & now it won't let me download any apps. Why?

Hi
I'm having the same problem on my iPads, iPods and iPhones. All use the same apple I'd for the App Store.
Has been like this for a few days. Happening with updates, new apps and if I delete and try to re-download.

I tunes wont open because of missing files how do i fix this?, i tunes wont open because of missing files how do i fix this?

every time i try to go onto itunes it says itunes cannot run because some of its required files are missing please reinstall itunes. and it wont let me do that either please help thank you

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.

Keeps saying damaged library. i have uninstalled and installed, deleted files and sent files to recycle. nothing works and now itunes won't even open.

i have repeatedly received the message that the itunes library is not valid and is damaged. i have uninstalled itunes between 6-8 times, sent files to recycled and still get the message. now, it won't even open....

Have you tried the procedure here?
How to recreate your iTunes Library
If not, that might do the job for you.

HT202159 I downloaded Dragon Express and now it won't open. It says it is INSTALLED but it won't open when clicked. Tried to trash it and start over but won't let me trash because it says it is open. But it isn't! Called mac help and they can't help e

I downloaded Dragon Express and think that it did not completely complete the download. However, it says that it has been installed and my account has been charged 50.00. However, when I click on the icon, it will not open. I have tried everything from restarting, trashing the app, but it continues to tell me that I cna't trash the app because it is open. I called apple support and they worked with me for about 30 minutes until they finally told me that the call had to end regardless of the fact that after all of their efforts, the problem was not resolved. He gave me a link to get a refund and said it was easy to navigate however, it led me nowhere. So now I am stuck with a worthless app, that does not work and a 50.00 bill to pay because I can't get support or link support to get a refund and even if I could get a refund I still have the Dragon express on my computer that does not work!!! HELP! I don't know how the app can be open when even support could not figure it out! When I restart, the finder window opens where it never did before.

Well first of all this is a public forum, so keep that in mind. The users here generally can not look up your case numbers.
If AppleCare didn't work out for you, I believe your next step is
iTunes Store Support
http://www.apple.com/emea/support/itunes/contact.html
Unfortunately, their case indexing is on a different database, and they will not be able to look up your case number either. However, their support is free, and despite it may take a few bounces of emails back and forth, there is a decent chance they may be able to get a solution.
Or... you can still try to shoot the **** with us here, which is Ok as well. But you'll have to keep in mind we can't look up your case numbers.
By the way, the link for a refund, I think is for the same link I just gave you, so on second though, mabye it's best to just go there.

Help! Reset the password and now master account at log in is missing??????

I really need you help on this. Today I was helping my younger cousin with his macbook. He lost his password so I put in the disk that came with it and held down C and went to Utilities/reset password and reset the main account password. I might have reset the Home Permissions and ACLs. I reboot the computer and in the login screen only show the other that was made and not the main account. So the master account is mission how do back so I can log in it. Can anyone help?
Mike

is the other account admin? if yes, log in as the other user and run the following terminal command
sudo rm /var/db/dslocal/nodes/Default/users/short-user-name.plist
Instead of short-user-name put in the above the short name of your main user which is now missing. It's the same as the name of that user's home directory in /Users folder which should still be there.
You'll have to enter the admin password which you won't see as you type it. that's normal.
Please make sure you copy the command EXACTLY as given. it's very important. we don't want to delete the wrong thing here. this will delete the directory services record for the missing user.
Restart, log in as the other user again and try creating an account with the short user name of your main missing user in system preferences->accounts. it will say that a home directory by that name already exists and ask if you want to use it. say "yes".
this should bring the account back.
if the only currently existing account on the computer is not admin then boot from the install DVd and using the password reset utility activate root (=System administrator). then log in as root and perform the same steps as above.

I tried to open too many files in preview and now it won't open at all.

how do I change the settings so that it doesn't keep trying to reopen these same files?

I have tried to force close/quit but every time I try to get back into the "preview" application, it tries to reopen the same files. It may actually be a setting with all of my applications as they all open the file I was last working on. Is there a way to change that?

Please see solution in http://kb.mozillazine.org/Problematic_extensions
for "McAfee Site Advisor".
(Windows): For best results you should uninstall '''McAfee Site Advisor''' from Control Panel > add/change programs (Programs and Features). Reboot the system. Then Reinstall from http://www.siteadvisor.com/ and reboot the system. When installing refuse other suggested (crapware) applications.
