A window that keeps poping up ( Java Script Application) uninstal set.

This happends everytime I use FireFox. It dosen't when I use Internet Explorer but; it's slow. I have windows XPSP3

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 > Add-ons > Extensions
''or''
Tools menu > Add-ons > Extensions
Any luck?

I am unable to do anything for the last 2 days due to a message I keep getting that says: (Java Script Applications) uninstal set. I click OK and it comes right back. I can't proceed until it is off.

As soon as I open Firefox the message box pops up. Java Script Applications uninstal set. I have to click on it about 10 times for it to close. Then I can click on one thing and it comes back. I have shutdown my computer and restarted it several times. I don't know how to get rid of this message.

This issue can be caused by an extension that isn't working properly.
Start Firefox in [[Safe Mode]] to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
* Don't make any changes on the Safe mode start window.
* https://support.mozilla.com/kb/Safe+Mode
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
* Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
In Firefox 4 you can use one of these to start in [[Safe mode]]:
* Help > Restart with Add-ons Disabled
* Hold down the Shift key while double clicking the Firefox desktop shortcut (Windows)

Goofy window that keeps poping up...

I have an Intel iMac that I just updated to Mavericks and I'm getting this window:
whenever I open the Notification Center with a message open to Google. What I have to do in order to get this window is open the Notification Center, click on the Messages button at the top of the window (which opens a new message), and then close the Notification Center and reopen it with the message still open. Entering my Google password makes no difference. It's very consistent, and quite annoying.
I have been trying everything I've seen suggested including changing my password, reinstalling OS X, and probably a few others I'm forgetting. If there's anything you folks can do to help me that would be great!

Hi Peter,
OK, I ran the program EtreCheck and here are the results:

Hello Bo.
It's possible that you are having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not caused by one (or more than one) of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] (don't forget to select ''Disable all add-ons'' when you start safe mode). If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme and [https://support.mozilla.com/en-US/kb/Troubleshooting+plugins this one] for plugins.
If you need support for one of your add-ons, you'll have to contact its author.

Why do i keep getting Java Script Application saying uninstal and every time i click on my mouse the pop up appears and its sometimes hard to get rid of it. Please help. God Bless

As soon as I log on to Firefox this pop up appears on the screen saying Java Script Application and under neath it it says uninstal and beside uninstal is a yellow triangle with a exclamation mark inside of it. Every time I click the mouse the pop up reappears over and over. It's really a nuisance and I need your help.The word uninstal is spelled like you see it, even though it's spelled wrong.Thank you and God Bless

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.

On the left side, click Extensions
Then disable as many as possible and restart Firefox.

Hello there, there is a rare window that keeps popping up every time i start Logic. I'd like to send a screenshot... anyway, it's a "tempo" window with strange layout about midi effects and so,.... is it normal? How can i improve this? Thanks.

hello there, there is a rare window that keeps popping up every time i start Logic. It's a "tempo" window with strange layout about midi effects and so,.... is it normal? How can i improve this? Thanks.

Hmm, that's some sort of MIDI Arpeggiator setup in your environment. Strange that you don't know it, this has to be custom-installed, it is not part of the standard setup.
You can do two things about it:
1.unlock your current screenset (shift-L), then close the (Bass Driver) window, then relock the screenset (shift-L). Next time you open up this project you won't see the Bass Driver, but it is still in the project.
2. You can remove the whole page: open the Environment (cmd-8), then go to the dropdown menu arrow top left of the Environment window and select the Bass Driver layer. If it is selected, dropdown again and choose Delete. Now Save your project under a different name (Save As...), so that you still keep the Bass Driver setup in the original project. If you don't need to keep it, you can simply Save.

I have a black window that keeps coming up and telling me the various tasks that I am handeling. It came after opening a power point and now I cannot make it disappear. It frames all windows and programs that I open with a black line. Help please...

Go to System Preferences - Accessibility - Voiceover - turn off Voiceover. The shortcut is command-F5, so possibly you pressed that accidentally.

Ever since I downloaded FF's v6, everytime I go to YouTube and open a video, I get an error message that says: "[Java Script Application] Error: Div is null" How do I fix this problem?

If I go to YouTube, no matter what video I click on to watch, the error message "[Java Script Application] Error: Div is null" pops up. It started happening right after I updated to FF v6. I also have installed the latest version of Java. I submitted this question a few weeks ago, but never received a reply.
Thanks for any help you can provide to fix this.

hello, can you try to replicate this behaviour when you launch firefox in safe mode once? if not, maybe an addon is interfering here...

Java script application appearing everytime i open a new tab

Hi,
Everytime I open a new tab on my computer, a message pops up with Java script application in a box with a yellow triangle with an exclamation mark symbol. I have to click ok twice before I can continue using the internet.
Can you please tell me how to fix this, I think this happened after I upgraded my mozilla website.

hello annap2677, you have quite a few malicious addons present. please try these steps:
# [[Reset Firefox – easily fix most problems|reset firefox]] (this will keep your bookmarks and passwords)
# afterwards go to ''firefox > addons > extensions'' and in case there are still extensions listed there, disable them.
# finally run a full scan of your system with different security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] and [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner] to make sure that adware isn't present in other places of your system as well.

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

Whenever i open gmail it appears which says-"java script application,Error: Illegal operation on WrappedNative prototype ",how this will resolve,anyhow.object

Question
whenever i open gmail it appears which says-"java script application,Error: Illegal operation on WrappedNative prototype ",how this will resolve,anyhow ?

This is usually caused by an extension that is using a name for a variable or function that has become a reserved variable name and thus can't be used anymore. 
You will have to check if there is an update is available for your Firefox 29.0a2 Aurora version.
If it works in Safe Mode and in normal mode with all extensions (Firefox/Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit)

I'm all of a sudden getting a ( Java Script Application "download error" message) when trying to use Ant Video Downloader. What could cause this?

When an FLV is playing and I want to download it. I click on the Ant download button. A little window appears reading ( Java Script Application "download error" message)

This works for me on YouTube.
Cancel the download and then immediately right click and choose retry.

Just updated firefox, every time I open it I get a message about a java script application

The message says
[Java Script Application]
can't create mcaffee plug-in object. TypeError: Components.classes[cid] is undefined

That indicates that you are using an add-on that is not compatible with Firefox 4. For details of how to troubleshoot this to find out what one is causing the problem see https://support.mozilla.com/kb/Troubleshooting+extensions+and+themes
For chloe_am it indicates the version of McAfee add-on is not compatible.

I can't get firefox to launch I'm getting a java script application - bbyln is nt defined

I can't get firefox to launch. I'm getting an error report:
java script application - bbyln is not defined

[ I've solve ] Well, I was too upset from the errors of babylon, sometimes it didn't allowed me to browse internet and oftentimes it ruined my new(default) tab opening parameters, so finally after damn research i figured it out how to get rid from these errors.; these files (software /errors) weren't visible anywhere e.g. control panel, system32 etc. i got em from C:\......, then i deleted em and got a complete calm. so here you go and remove both things;
C:\Program Files\Mozilla Firefox\searchplugins (bbyln.dll).
C:\Program Files\Mozilla Firefox\extensions (bbyln folder)
after to remove (babylon) relevant files restart your Mozilla firefox. WAIT. WAIT. don't forget to complement me...just say loudly....Well done dude, You're Genius ....O_o....!!!!
Sure, it'd be helpful because its not me its my experience talking to you.

i am using vista sp1, recently while opening Firefox or any link within it a dialogue box appear " [java script application] An error occured throwing an exception" . however both cancelling or accepting opens the link or firefox but its nagging plz help
== This happened ==
Every time Firefox opened
== few days ago

The code is not working because you made a mistake somewhere, duh! So figure out what (hint: firefox javascript console, it's your friend) and fix it!
And next time when you post code: use the [ code ] tags to pretty format your code, as it is now it's unreadable.
