When I try to start Firefox a user control box opens. I have lost the link to Windows 7 because I made a mistake and clicked on compatability. Can you help?

Problem started yesterday. A message kept flashing on screen stating that a script was running in the background which might affect programs running. Clicking yes to close the program did not work as the message kept flashing up. Clicking no did not work either, so I logged off. I then found there was a problem with MacAfee, which I cured. This stopped the message from reappearing. However, since then I have not been able to access Firefox, which is definitely my preferred browser. However I do not want to instal Firefox again if I can avoid this as I don't want to lose my bookmarks.

Please reinstall firefox with option to retain user data. Firefox files may have been corrupted due to that unresponsive scripts.
Please remove unnecessary addons to keep ur fox fast.

After installing a new version of Firefox, I get the error message "The procedure entry point JS_GetOperationLimit could not be located in the dynamic link library js3250.dll" when I try to start firefox. Elsewhere in the forum a complete reinstall is suggested; however, I can't do that because of my company's IT policies. Is there any way to solve this problem WITHOUT a complete reinstall? Thank you!

If you can't reinstall Firefox yourself then you need to contact your IT department and ask them to check the Firefox installation.
It is possible that some files got broken with the latest update.

Hi,

Go to settings for google shortcuts, follow link to homepage and upload latest version, it has not yet been approved by Firefox, but works and solves the bug.
Hope this helps.

When I try to start Firefox, I get a message that it is already running but not responding and I can't run another Firefox at the same time. I uninstalled and reinstalled. No change. Tried various other suggestions. Help!!

When I try to start Firefox, I get a message that it is already running, but not responding and that I should close it before trying to run another Firefox. But I cannot find a way to close Firefox program that is not running as far as I can see. I tried uninstalling and reinstalling Firefox, but that did not work. I've tried various other things, but no luck. I thought programs should stop when the computer is turned off, but that didn't work either.

How are you opening the Profile Manager?

Sounds that Firefox is still or already running.

Not using any mouse pad, I have a very smooth desktop. But I just tried to use a sheet of A4 printing paper, but no result, the problem persisted.
Someone on this forum suggested, that USB3 may interfere with the magic mouse.
I have 2 LaCie HDD's about 70 cm away from the mouse, I use them on Thunderbolt. But in operation or not - the result is the same, the mouse plays up! Just now I was clicking the desktop and the mouse created a new folder!!
Thanks for the advice, Bee

This issue can be caused by the McAfee Site Advisor extension

Just had this same problem. Based on other suggestions I found on the web, went to C:\Program Files\Mozilla Firefox and deleted all files that ended with upgrade and/or delete. Then I was able to uninstall Firefox and then reinstalled. Hope this helps!

After upgrading to version 11.0.4.4 I get a "Itunes has stopped working" message when I try to start a movie on my PC. I have updated Quick time and previous version of Itunes worked great.

One thing is for sure, and that is if the only page i visit is the Google homepage (not logged in) or this site (mozilla forum), the problem does not occur, ever. I can't make it happen.
If i visit yahoo.com (not logged in) (or ighome.com, logged in), as examples, it happens every time.

When i try to add music from itunes to my ipod, Itune tells me the music on my ipod came from a differnt libray and wants to erase my whole ipod. i just loaded my ipod two days ago. i don't want to replace everything every time i want to add two to songs. My MacBook Pro is the only autherized computer.

To prevent a sync when plugging in the iPod/iPhone - hold down the 'option' and the 'command' keys when plugging in the iPod/iPhone - key the keys down until the iPod/iPhone is listed under the Devices list in iTunes - this will prevent a sync from taking place and you will be able to change your settings.

When I select my iPod touch in iTunes the buttons are inactive when I try to sort by name, artist etc. Also about half of the links under 'file' etc are not active.

Further to my question, when I plug in and select my iPad 2 I don't have the same problem. I have restored the settings on my iPod Touch and updated both iTunes and iPod Touch software and restarted my iPod touch. Nothing has made any difference.

Hello there, Gemss.
The following Knowledge Base article offers up some great recommendations for the issue you're describing:
iTunes repeatedly prompts to authorize computer to play iTunes Store purchases
http://support.apple.com/kb/TS1389
Although all of the scenarios may be applicable, many folks find that the following section helps resolve their issue most often:
Authorize using the correct account name
The items you're trying to play might have been purchased using a different iTunes Store account. To determine which account was used to purchase an item, follow these steps:
Select a purchased song in your library and choose File > Get Info.
Click the Summary tab. Note the Account Name that appears in the list. This is the account name (Apple ID) you'll need to use when authorizing your computer to play this purchase.
Note: The account name that appears is the one you used when purchasing the item and does not change if the account name (Apple ID) changes.
If you've authorized the Apple ID that is shown in the Summary tab, you can check the purchase history for that Apple ID from Store > View My Account. If your purchase history does not reflect the purchase of the items in your iTunes library, consider any other Apple ID you may have created, and authorize the computer for your additional Apple ID.
If you forgot the password to one of your accounts, you can recover it using Apple's password-recovery website.
Thanks for reaching out to Apple Support Communities.
Cheers,
Pedro.

Don't know if there is an option make the download window stay up, but you can bring it back with Ctrl+J then right-click on the download to open the folder it was downloaded to.
