I can't use my add-ons. When I try to click on it, it says you must be logged in?

I recently downloaded firefox. I downloaded a few add-ons and dragged them to my toolbar. However, when I try to use them, I get the message that I must be logged in. I have no idea what I am supposed to log in to?

These sorts of msi-related troubles have gotten more complicated to deal with ever since Microsoft pulled the Windows Installer CleanUp utility from their Download Center on June 25. First we have to find a copy of the utility.
Let's try Googling. (Best not to use Bing, I think.) Look for a working download site for at least version 3.0 of the Windows Installer CleanUp utility. After downloading the utility installer file (msicuu2.exe), scan the file for malware, just in case. (I use the free version of Malwarebytes AntiMalware to do single-file scans for that.)
If the file is clean, to install the utility, doubleclick the msicuu2.exe file you've downloaded.
Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove".
Quit out of CleanUp, restart the PC and try installing iTunes again. Does the install go through properly this time?
(If you do find a clean download site for the correct version of CleanUp, please don't tell me where it is. Without wishing to sound paranoid (although I grant it does sound paranoid), there is a non-zero chance that posting links to download locations for the utility here at Discussions leads to that download location being shut down.)

Is there any way to create a time machine backup to an external hard drive with content already on it? I have a hard drive that i have used for pictures but when i try to run a backup it says i need to start from a blank drive. Can i get around it?

It would be much better if you had separate drives for the pictures and Time Machine backups.....but, if you want to use the same drive for both purposes, temporarily move the folder with the pictures to another location for safe storage.
Run the Time Machine backup on the hard drive and verify that everything is working correctly. Time Machine will format the disk for you in Mac OS Extended (Journaled) as part of the backup process.
Then move the folder with the pictures back to the hard drive with the Time Machine backups.
When you have tested to make sure that everything is working again, then and only then should you delete the folder with pictures from the temporary storage area.
Again....it would be much better to keep Time Machine backups on a drive just for that purpose, and other data on another drive for that purpose. This is clearly one of those times when the fact that you can do something does not mean to imply that you should do it.

Have you attempted to reset the SMC? That would be the first step. Hold the left control, option, shift key and the power button for about 5 seconds and release. Then try to reboot. Might as well reset the PRAM as well. Hold command, option, P, R on start up until the machine restarts. If that doesnt' have any affect we'll have to dig deeper into a potential hardware failure.
If this method doesn't work, check the webcam that will tell the problem is on the iSight & WiFi cable. If your webcam is ok, then it'll be the WiFi card problem. Hope it can help ;-)

I had the same issue with my apple tv 3rd generation. I rented Sinister and selected the "rent and watch now" option. Half way through the movie I accidentally pressed the menu button. When I looked for the rented movie on my apple tv I could not find it. Not even above the movie pannel where "purchased" and "top movies" comes up on the main menu. the apple tv suggests to go to settings>downloads but I don't have that option. I did go to settings> itunes store> check rentals but that didnt work either. It took too long to even check. Thank you because this SOLUTION worked great.
SOLUTION: How to reset apple tv 3 3rd generation to view rented movies:on the apple tv remote: press and hold "menu" to go to the main menu. Select SETTINGS> GENERAL >RESET >RESET ALL SETTINGS. After the apple tv resets, input all your information again and your rented movies should be visible when you cruise above the "movies" section. THANK YOU!!
Apple needs to solve this issue because honestly it took me 3 hours and a half to watch a movie that only lasted 2 BECAUSE I wast trying to solve the issue, reseting and all. blahh.

When I try to update Firefox it repeatedly says Firefox must be closed to proceed with install. I even get the same message when I try to uninstall the existing version of firefox. How do I close Firefox???

When I try to update Firefox it repeatedly says Firefox must be closed to proceed with install even tho Firefox is closed. I get the same message when I try to uninstall the existing version of Firefox. How do I close Firefox??? The same thing happens when I try to update other programs. When a program is off what else do I have to do to turn it off??

If you get an error message that you do not have sufficient permissions or have other problems with updating to update then easiest is to download the full version and trash the currently installed version to do a clean install of the new version.
Download a new copy of the Firefox program and save the DMG file to the desktop
* Firefox 4.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Firefox 3.6.x: http://www.mozilla.com/en-US/firefox/all-older.html
* Trash the current Firefox application to do a clean (re-)install
* Install the new version that you have downloaded
Your profile data is stored elsewhere in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder], so you won't lose your bookmarks and other personal data.

HT201272 all of music downloads in my library show a exclamation point prior to the check box, when i try to click the song, it says unable to locate even though all the preferences are saying it's there. where is my music? please help

I was trying to sync my ipod and for whatever reason my iTunes wasn't recognizing my ipod anymore and asked if I wanted to erase it and basically start over. So I said yes, thinking it would then put my music library back on my ipod, but instead now it shows all my music but it won't play or sync. When I try to play any song, it says it can't be located and asks if I would like to locate it, but I still can't find it! I've had to go into the iTunes store and redownload songs and that works. But I would really like to just locate my library wherever it is in my computer. Help!

I'm in the same boat...so far no one has helped here

5.0 shows installed on ff help. Programs and features shows only 3.6.8. When I try to download 5.0 computer says it must restart to finish installation of another ff. Restart has no effect. Looks like I am stuck on 3.6.8. Please help.

This computer will not update to 5.0. I have tried to download and install 5.0 for many weeks. My OTHER computer updated fine. When I try to install 5.0 it say to restart to finish installation of another firefox. Restart does not change anything.
I click on ff help, about ff and it says 5.0 is installed. I look on programs and features and only ff 3.6.8 is listed. I have tried clean ups, update java, plugins and stuff like that with no change to this issue.

I guess no one cares.

Newest version of firefox downloaded, i need an older version so that my adobe acrobat X pro 10.0 and Norton can be used as add ons. Which one please?

I need a different version of firefox to work with my adobe and norton. can someone please help me. I have tried the 32, 30, 29 and 22, they all say the add ons for those 2 plus one more add on i have say not compatible. I need firefox for work. Any info on how to make any of those work or which to try to work would be greatly appreciated. Thanks in advance.

Norton updates frequently, so that should not be a big problem. If you run LiveUpdate several times, you likely can get a compatible toolbar. http://community.norton.com/blogs/product-update-announcements/firefox-32-support-norton-toolbar
The Adobe "Create PDF" extension is a more complicated issue. If you are stuck with version 1.2 (perhaps the last update available with Acrobat X?), this thread might be relevant: [https://support.mozilla.org/questions/999499 Firefox 29 broke Adobe Acrobat - Create PDF 1.2]. However, for security reasons, it would be better to try to figure out how to get it to work with Firefox 32.

I'm using movie 11 and when i try to share with idvd it says user parameter error

i'm using imovie 11 when i go to share with idvd it says user parameter error

Share to iDVD only works if your original footage was AVCHD (or anything that gets converted to Apple Intermediate Codec, like HDV) or DV.
If your original footage was h.264 or something like that, you should SHARE to the Media Browser and bring the movie into iDVD through the Media Browser there.

My iPhone 5s was just updated recently to 7.1.1. Now my calendar information got deleted and I can't add any events to my calendar. The button in the top right corner should be orange but it's grey and it won't let me add events when I try to click onit

I'm trying to add events to my calendar after they got deleted and it won't let me because the + is grey when it should be orange. Does anyone know what to do?

You are on Windows 2000, you do not have a "Firefox" button, and should consider yourself to be fortunate in that you still have menus and don't have to do anything to get the menus back instead of the "Firefox" button. (The same applies to Windows XP users).
Use the "File" menu to get to Import. You are not on Windows 7 or Vista, and don't have to put up with the nonsense added for Aero.
If you want the "Firefox" button you can get it with View -> toolbars -> (uncheck) Menu Bar. The menu bar and the "Firefox" button were supposed to be mutually exclusive (which is impossible in some cases without being incompatible).
Once you are using the "Firefox" button ...
Use the "Alt" key to view the menu bar (temporarily) containing File, Edit, View, History, Bookmarks, Tools, and Help. On Windows 7 and Vista, the menu bar was hidden by default in Firefox 4 and above. These menu items are more or less available under the "Firefox" button which has the most used of the built-in Firefox menu items available in a different format.
To get back to having menus again. "Firefox" button -> Options (second column) -> (check) Menu Bar
You can make '''Firefox 7.0.1''' look like Firefox 3.6.*, see numbered '''items 1-10''' in the following topic [http://dmcritchie.mvps.org/firefox/firefox-problems.htm#fx4interface Fix Firefox 4.0 toolbar user interface, problems (Make Firefox 4.0 thru 8.0, look like 3.6)]. ''Whether or not you make changes, you should be aware of what has changed and what you have to do to use changed or missing features.''

My iPod is locked and says connect to iTunes when I try to connect it a message says you have to type in the passcode to connect

My sister's iPod is locked up and we need it unlocked now!

You need to place the iPod in recovery mode and then connect the iPod to its syncing computer and restore from backup. For recovery mode see:

On i-pad, when try to enable itunes match, it says, "you are not currently subscribed to iTunes Match. Use iTunes on your computer to subscribe." I am subscribed though! Then it says no my request and item not available in the U.S. store. WWJD?

On i-pad, when I try to enable itunes match, it says, "you are not currently subscribed to iTunes Match. Use iTunes on your computer to subscribe." I am subscribed though! Then it says no to my request and, "item not available in the U.S. store." My Mac will not use update iTunes to any later version than the one I have because my os is also out of date, but when I try to update that i cant, so what do I have to do? Please don't tell me I have to buy a new Mac to be up to date.

On the iOS device you must be logged into the store with the exact same Apple ID you used to originally purchase the service. Go to Setting > iTunes & App Stores and if necessary sign out/in and then enable iTM.

I can't use my add-ons. When I try to click on it, it says you must be logged in?
