When I use firefox as my browser I keep getting the error message "uninstal set" Java script. This is extremely annoying and I can't get rid of it. It pops up every time i go to a different page. My OS is Windows Vista.

This has just started since I upgraded my firefox.

Other users have reported that this is caused by one of their add-ons. I suggest going to the Add-ons page and disabling everything that is not essential, and then restarting Firefox. Hopefully it's not caused by something you really rely on.
orange Firefox button ''or'' Tools menu > Add-ons
On the left side, click Extensions
Then disable as many as possible and restart Firefox.
Any luck?

    Welcome to the Apple Community.
    I have seen previous versions mentioned in a pop up message before on iCloud.com, but I'm not really sure at all how it would help, as I couldn't get it to do anything.
    The best advice I have at this time is to back up your work on your iOS device by regularly saving it to iTunes, if anything goes wrong you can then either load it into the numbers app again on the device or recover it via iTunes on your computer.
    My syncs are immediate, I never get chance to see if it works in the background, sorry.

  • I'm trying to download Firefox 4 onto Windows 7 platform. I keep getting an error message that says Java script has an error in Chrome ? Unable to complete download. Constant ahngs & freezes

    I am running on Windows 7 platform. I tired to download the latest Firefox 4 release. Each time, I get the message that "there is an error on line 20 in Java script Chrome that is preventing the download from continuing. I've run Fox in safe mode & still get the same message.

    Your More system details list shows that you use Firefox 4:
    *Mozilla/5.0 (Windows NT 6.1; rv:2.0) Gecko/20100101 Firefox/4.0
    Are you trying to (re)install Firefox 4 or do you get that error if you start Firefox?
    Do a clean (re-)install:
    * Download a fresh Firefox copy and save the file to the desktop.
    * Firefox 4.0: http://www.mozilla.com/firefox/all.html
    * Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
    * Don't remove personal data if you uninstall the current version.
    * It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
    Your bookmarks and other profile data are stored elsewhere (not in the Firefox program folder) and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.
    If that still doesn't work then create a new profile as well.
    See [[Basic Troubleshooting#Make_a_new_profile|Basic Troubleshooting: Make a new profile]]
    If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)

  • When I turned my Macbook on and signed in, it has been shutting down automatically and restarting itself immediately after opening the desktop. The error message said, I'd shut down my computer unexpectedly. How can I get it to stop shutting down on me?

    Since downloading OS X Mavericks, my computer has been shutting down midway of starting up. Please help! The problem began after downloading the software free update. Now when I start my computer, it will starts up normal but when the desktop appears, there will be an error message that I shut down my computer because of an error and if I would like to open the applications that were open before the sudden shut down I should press continue. Then when I select continue, it will open up another communication window that my computer is restarting because of an error. Then the screen will revert to shutting down and restarting again. This has been going on now all morning. Can someone hlep me on how to resolve this issue?

    Very Important, how much Free Space is on your Hard Drive first of all? Click on the Macintosh HD on the Desktop, then do a Get Info on it.
    Could be many things, we should start with this...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
    3. Click the First Aid tab.
    4. Select your Mac OS X volume.
    5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
    If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
    Do they launch OK while in Safe Mode?

    I am using Firefox ver. 3.0.19 and I have Windows 7 which came with a new computer. When I use Firefox as a browser I cannot print my emails. I get an error message: "pcfax not availabe". If I use IE I have no problem printing the emails.
    == This happened ==
    Every time Firefox opened
    == From day 1 with the new computer about two weeks ago.

    It sounds like you have the wrong printer selected.
    When you get the Print window, pick another printer from your printer dropdown. You seem to have a fax printer selected instead of a physical printer.

    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!

  • Why do I get the error message "unable to load page (HTTP 502) when I try to open Mobile Web?

    I have an LG Octane 3 basic phone.   Does everything I need, phone and text, and I never was interested in web or e-mail capabilities until I recently upgraded our plan to the "More Everything" and was able to use data and check e-mail and access the internet.   Whenever I try to open Mobile Web, I get the error message "unable to load page (HTTP 502)".    As of March 31, 2015, all of us basic phone users lose the "Mobile Email" app on our phones, and will have to access web versions of our e-mail via the web.  Which is currently unavailable and doesn't work.
    Over a week ago, did a chat session with a tech support rep, and she indicated that either she or an engineer would contact me with how to fix the problem.   Have not heard anything from anybody, and the deadline is approaching quickly.   Have no need of all the excess features of a smart phone, nor do I wish to be forced to jettison a perfectly working phone for my needs and buy something I don't want to be able to do 2 simple things.............check e-mail to see if there's something that needs to be answered right away, and to check traffic reports when I'm on the road, or find something in an area with which I'm not familiar.     Not really too much to ask, you would think....   )
    Has anyone else had this same problem, and if so, how do we fix it....???  My next move is a phone call, but those haven't always been very productive.
    If any of you have any ideas why this error keeps coming up and the web can't load, and some on how to fix it, I would really appreciate some advice.
    Thanks in advance.
    Karen

    Since the chat session got no reply, I contacted Verizon by phone and a very nice level 2 tech created a trouble ticket and sent it up the food chain.  Got a call back, maybe 2 days later, and had a nice, although very long session with a higher level tech.  They had determined that the browser for the LG Octane is an old one and no longer supported by Verizon.    We tried everything we could to download the Opera browser, but since I was totally unable to get Mobile Web to work, couldn't do it.   The only other possible "fix" was to totally reset the phone to factory specs and try it again.   That would mean a lot of work on my part to move anything I didn't want to disappear off the phone, and find a place to forward texts that had to be saved.   Caught our tenants lying about why the rent was late (again), and need that for when I put them back on a lease....  
    Long story short is that unless we try this total reset, which isn't a sure fix, either, anyone who isn't able to access the Mobile Web with the LG Octane will have to change their plan to avoid paying for data that you can't access using any method. 
    I ran a test with an app that I knew was no longer valid.....that was sending photos to PixPlace.   Got the exact same error message as when trying to access Mobile Web to get the web version of my e-mail.   That just verified that the 502 error is, at least in the LG Octane, for an app that no longer works.   After today, we'll get the same thing when we try to access Mobile E-Mail.
    Have to admit, it's a real ****-off, but this shouldn't surprise me, since Verizon won't repair older copper phone lines if you are in an area where FIOS is offered. 
    I am going to immediately change my husband's and my cell phone plan to one without data, and see what I can find that will still give unlimited calls and text.  The way my luck runs, they won't offer one for a decent price.  The other half has some very long-winded friends and he was always running over minutes, and some months are very text-heavy and I'd go over my limit.   Absolutely HATE touch screens, and am not looking forward to having to get a new phone.

  • I get the following error message whenever I try to access email from Dice JobAlert. I don't receive the error for any other email I receive and I also don't get the error message when I access the email using Internet Explorer.

    This is the error message I received: A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete. Script: http://sz0150.wc.mail.comcast.net/zimbra/js/Startup1_2_all.js.zgz?v=110527090709:822

    Their browser detection script is out of date. The warning seems to come from this file: http://virus.info/api/load/file/js , specifically, the badBrowser() function.
    It's checking for "Firefox/1", which it finds as part of "Firefox/10".

    iTunes is updated and works fine and I am able to log onto my account. When I go to purchase a song, I get the error message "Your Apple ID has been disabled". I've tried different methods: changing passwords, making a new account with another email address, and emailing itunes tech support. I am curious as to how many others have been experiencing the same issue. When I googled the error, it seemed like it was happening extremely often with many people.
    We all love their products, but they always come with a lot of issues and horrible customer support.
    My apple Id is [email protected]

    My Iphone 4 is telling me the same thing and I believe I figured out what the problem is.  I had some fraudulent charges on my itunes account, so I call my bank and disputed the charges.  Right after I did that, I started getting the message "Your apple ID has been disabled."  I just realized today that the charges are not fraudulent, they are "in app purchases."  One of my daughters downloaded the game Top Girl which is FREE, but in the game Top Girl you use money in the game to purchase things.  It just so happens that the money you use to purchase things is real money MY Money!!!.  My daughter thought she was using play money in the game and had no idea she was using real money.  She spent $106.00 buying stuff.  Now I have to call the bank and tell them to release the hold and pay Itunes.  I'm hoping this solves the problem.  Here is the link to learn how to disable "in app purchase" on your iphone or ipad.

    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!
    == This happened ==

    == I installed a new version ==
    == User Agent ==

    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.

  • I get the error message in QuickTime "operation stopped the operation is not supported for this media" most times when I try and export an .AVI file as something else (.m4v). I have not touched the file in any way (no trimming, clipping or other editing)

    I get the error message in QuickTime "operation stopped the operation is not supported for this media" most times when I try and export an .AVI file as something else (e.g. .m4v). I have not touched the file in any way (no trimming, clipping or other editing), all I want QuickTime to do is export the file in a compressed format. Bizzarely, if I shutdown and open QuickTime many times I can occasionally export a clip as another format (maybe one in 10 times). I have seen that other users have had a similar problem after clipping files in QuickTime but this seems to be a slightly different bug in that all I do is open the file and then try and export the file as is - either way, this is a very annoying bug

    @Z_B-B, thank you for taking the time to respond to my cry for help. However, the link you supplied does not address the problem: I am not trying to export from Final Cut Pro to QuickTime, I am trying to export from QuickTime to the rest of the world (like people's iPhones and Ipads) in .m4v format (so I am not emailing my freinds such huge files).
    If I were to spend hundreds of Dollars on a copy of Final Pro I could export directly from there and not have to bother with QuickTime, but I do not take enough video clips to justify the cost. I must say that I never had any of these problems before I decided to switch from Snow Leopard to Mountai Lion.

    Possibly the drive is full
    Possibly the permissions are not set to WRITE permission
    Possibly there has been a "user mistake" and you think you are copying to a drive you have been using for over a year but something has accidentally changed and you're copying to a different location
