How to solve firefox crashing and continuous "unresponsive script" messages?

I've had this issue for a couple days now. When in firefox and having multiple tabs open, the tab that I am on will freeze and an "unresponsive script" message will come up. When I only have one tab open, the browser will shut down completely without any message. I have already tried disabling all of my plugins, allowing the script to run longer, restarting firefox, and even uninstalling and reinstalling firefox. None of these seem to work for me. Does this mean I have a virus? Are there any other things I can try or should I have this looked at?

Try this for your mac computer:
Please do the following to give us crash IDs that will help us understand more about the crash.
#'''(OS X 10.6 or previous)''' Click the '''Finder''' icon in the dock. Your home folder will be selected. In the right side of the window, click the Library folder to open it. Then open the "Application Support" folder, the "Firefox" folder, the "Crash Reports" folder and finally the "submitted" folder.<br>'''(OS X 10.7 or above)''' Click the '''Finder''' icon in the dock. On the menu bar, click the '''Go''' menu, hold down the '''option''' or '''alt''' key and select '''Library'''. A window will open containing your Library folder. Then open the "Application Support" folder, the "Firefox" folder, the "Crash Reports" folder and finally the "submitted" folder.
#Open the 5 most recent files with a text editor and copy the IDs.
#Paste each ID with '''bp-''' into the reply window on the forums.
Thanks in advance!

Every time I start up FireFox I get an "Unresponsive Script" message, is there any way to fix this as it's slowing down everything

Here's the message I get:
"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: file:///Applications/Firefox.app/Contents/MacOS/components/nsBrowserContentHandler.js:291"
I've tried deleting firefox and re-downloading and installing it but it's no help.

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).
* Don't make any changes on the Safe mode start window.
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.
* 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")

Flash Builder 4.5 with Firefox - crashes and no performance data. How to fix?

I am an experienced Flex developer, but new to the Flash Builder 4.5 Profiler. I'm using Firefox 5.0 and Shockwave Flash 10.2.153.1. Windows XP.
I have several problems:
1) in the profile view during a run, the buttons are dimmed and therefore I cannot "Capture Performance Profile".
2) almost every time I run, the Flash Player in Firefox crashes (And now worse, using that same profile, Firefox crashes randomly, but quickly on ANY web pages. I smell a re-install of Firefox coming.)
3) there is the option to configure for the Standalone Flash Player and a browser. How do I say WHICH one to use for a given profile run?
If I configure the browser to be IE, Firefox runs anyway.
Any ideas? Suggestions? Thanks for the time.

I have solved the crash by reinstalling the latest Flash Player.
The configuration issue is not as important.
The solution was simple. In the "Profile" view, select the "[Running]" instance. This enables the important buttons, like "Capture".
This causes a "Performance Profile" line to appear, linked to the running instance. Double click to view the info.
Thanks for listening.

Firefox crashed and after restarting, tabs i had open were gone and weren't in the history either. It didn't give me the option of restoring, how do i get them back?

Sorry , you probably can not get them back.
You may have bookmarked them, or have them as part of the History previously stored and still searchable, but unfortunately otherwise you are unlikely to get them back. Firefox does to a certain extent back up bookmarks automatically but not the history.
If you get problems with crashes see [[firefox crashes]]

After mozilla firefox crashed and a restart, the Firefox Developer Edition opend - how to open the normal firefox browser ?

after mozilla firefox crashed and a restart, the Firefox Developer Edition opend - how to open the normal firefox browser ?

See if this works for you.
Open up Tools > Options -> General and toggle the first preference - '''Allow Firefox Developer Edition and Firefox to run at the same time''' - to get back to your previous Aurora Profile. It will tell you to restart Firefox.
If there's a check-mark in the box for that pref it shows the Aurora Profile, if you remove that check-mark it shows the Developer Edition Profile.

I use Firefox frequently and continuously I receive a message "unresponsive script"

I continuously receive "unresponsive script" message when I try to open an new page. My system seems to be rather ponderous.
== This happened ==
Every time Firefox opened

Do you have that problem when running in the Firefox SafeMode?

# Question
Firefox crashes and when attempting to launch after the crash it won't launch; throwing an error msg that " js.3250 can't be found" - but same file is in Mozilla directory.
I must then download new 3.6.8 and lose all tabs and history.

I have a similar problem. Recently my FF8 has been crashing a lot. It regularly locks up an entire core of my PC and often just shuts down. It has just done it a moment ago and when it started back up it did the whole "this is embarrassing" thing and asked me if I wanted to reload my tabs. I deselected the one that I was trying to view as I suspected that it may have been the cause (unlikely; it was node4.co.uk) but anyway, let's skip it just in case. Click on the button to restore and up pops my homepage only. So all of my other tabs, which I was using for work incidentally, are gone.
This is not the first time this has happened on FF8. It happened a lot recently on FF6 I think it was (so hard to keep track now, Mozilla) and I switched to Chrome as a result, but it turns out that it crashes even more than FF6 did. FF7 was a vast improvement but FF8 is so unstable/unpredictable for me at the moment that I think I'd rather use IE9 than this. It's driving me mental, clearly! I wish I could kill the process manually and have it retry restoring tabs. Hey, there's an idea Mozilla; give us a menu item that allows us to restore the session to how it started to try again or at the very least get a list of the pages we were looking at. They don't show up in Recently Closed Windows and the Restore Previous Session is greyed out too. Gah! Help!

"Warning: Unresponsive script" message and Firefox v16+

I recently upgraded to v16, and then v17. In both cases I repeatedly received the dreaded "Warning: Unresponsive script" message, so frequently that the browser became unusable.
https://support.mozilla.org/en-US/kb/warning-unresponsive-script
I reverted to v15 and now I NEVER get the "Warning: Unresponsive script" message anymore
Just so you know...

'''Try the Firefox Safe Mode''' to see how it works there. The Safe Mode is a troubleshooting mode, which disables most add-ons.''
''(If you're not using it, switch to the Default theme.)''
* You can open the Firefox 4.0+ Safe Mode by holding the '''Shift''' key when you use the Firefox desktop or Start menu shortcut.
* Or use the Help menu item and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
''Don't select anything right now, just use "'Start in Safe Mode"''
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shift key) to open it again.''
'''''If it is good in the Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one.
Please follow the [[Troubleshooting extensions and themes]] article for that.
''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''

Every time I place a bid on Ebay my firefox crashes and must be restarted.

Every time I place a bid on Ebay my firefox crashes and must be restarted. This is the only time this happens. It seems to be ok until I actually confirm the bid and within a second or two firefox crashes.

This is most likely caused by '''The Browser Highlighter''' add-on. Uninstall or disable this add-on from Tools -> Add-ons -> Extensions. You could also try finding an update for this extension.
See [[Uninstalling Extensions]] and https://support.mozilla.com/en-US/questions/682558
If that does not solve the problem:
Go to the address '''about:crashes''' and tell us your latest crash IDs. We can then look at the data specific to your crash and have a better idea of what is causing the problem.

Firefox crashes and all website pages loose their formatting and pictures, and links are broken

I’m currently running Firefox 18.0.1 on a 13” 2011 MacBook Pro 2.7 GHz Intel Core i7 with 8GB or RAM that is running OS X 10.8.2 Mountain Lion. I have been living with this problem for over a year and this same computer has had this problem while running OS X 10.7 and I think even 10.6. The problem also existed with earlier versions of Firefox including versions 17, 16, and possibly 15, it’s been so long I can’t remember.
The problem is that Firefox crashes (or something within Firefox crashes) and the screen “goes white” and by that I mean all the graphics and layout of a page like YouTube disappears and even though the links are there, none of them work. The page is just made up of text and broken links. Reloading the page does nothing so I have to close Firefox and restart it. (No reboot) On relaunch everything is back to normal and may last a few minutes, or it may crash again right away. Generally if I launch Firefox and use it and then go use some other programs, when I come back to Firefox it will then crash. Is this a Java problem? Is this a javascript problem? I really don’t know what it is but it has persisted through several operating systems and different versions of Firefox running on different operating systems. I’m stumped and can’t find anyone who’s ever seen this problem. Any help or clues would be greatly appreciated.
I should add that this problem is present on ALL webpages, not just one or a few. Safari works fine on the same machine and visiting the same websites. I have screen caps of the crashed pages but I don't know how to post them here.

Please type about:crashes in the URL bar and provide us with the latest crash ids. Please do not make a screenshot but instead copy and paste. Thanks!

Firefox came up with the unresponsive script message and now if frozen?

Firefox came up with the unresponsive script message. I clicked 'stop script' but now Firefox has frozen and is not responding to anything I do. I cannot click on anything. It will not let me close it down, uninstall it or shut down my computer.

Upgraded to FF 33 and installed English dictionary. Now FF is hanging frequently in www.morningstar.com and I believe elsewhere with the following:
Warning: Unresponsive Script
Script: chrome://browser/content/browser.js.17006
I do NOT understand the "chrome" reference.
This is quite annoying. I upgraded to FF 33 in order to try to get back spell checking in Morningstar posts which I lost back at FF 24, as I recall, but it did NOT solve the problem. Now I have this mess.

Since upgrading to 3.6.3, I have 3 problems: frequent crashes, frequent "unresponsive script" messages, and frequent pop-ups, even with pop-up blocker turned on.

Crashes are pretty random - can't link them to any particular site or action. The unresponsive script messages mostly come from e-mail sites (yahoo, gmail). Pop-ups are frequent and annoying, and may be causing some of the crashes.
== This happened ==
Every time Firefox opened
== I upgraded to version 3.6.3

I have the same problem and it's really frustating - although my main browser is Google Chrome, I use Firefox for all the RSS feeds that I subscribe to and sites that only have Firefox plug-ins. Will Mozilla FIrefox get this fixed with a newer version soon?

When firefox crashes and reopens it offers to restore pages hours/days old.

When firefox crashes and is reopened, it usually brings up the pages that were open during the crash, but many times when firefox crashes, it will offer to restore pages that I did look at but that are hours/days old.
e.g.
I will be on youtube, facebook, my school website, and pandora. Firefox crashes. I reopen. Firefox offers to restore google search, my email, and wordpress, which I had looked at the night before.

Most likely you have Office 2004 which are PPC-only applications and will not work in Lion. Upgrade to Office 2011. Other alternatives are:
Apple's iWork suite (Pages, Numbers, and Keynote.)
Open Office (Office 2007-like suite compatible with OS X.)
NeoOffice (similar to Open Office.)
LibreOffice (a new direction for the Open Office suite.)
