Firefox Support Forum

Firefox keeps freeing/hanging. First you will see the errors that pop up for me. Then the troubleshooting I have done to solve this problem.

Script Error: Script: http://z-ecx.images-amazon.com/images/G/01/browser-scripts/imageBlock/imageBlock-3190704718._V1_.js:773

For troubleshooting I have tried the following: disable addon's and restart in safe mode (did not help) disable theme and restart in safe mode (did not help) reset firefox (did not help) uninstalled Firefox & removed all traces of browser from my computer (yes even the registry was removed)

I am not tech savvy but the script errors made me think of Javascript. I went to about:config and searched for Java when javascript.enabled showed up I disabled and the problem has disappeared.

I know I need this javascript enabled. I cannot do much of anything at my site with is disabled.

Does anyone have any suggestions on how to fix this script hanging problem.

Thanks for any help.

I am getting a solid red screen with screeching sound saying a web site is trying to do something to my computer and that it's a FIREFOX CRITICAL ERROR and I need to call help desk. The only way I have found to close the window is to open Task Manager and close Firefox. Sometimes after rebooting the page will go away for a period of time but it always comes back. HELP! How do I get rid of this monster? The Windows 10 Virus scanner won't clear it and neither will Malwarebytes malware scanner.

Thank you, Jake

I can't open a new window. I can't select preferences. I can't shut it down even when I try to force quit. Going to the finder and shutting down does not work. This prevents me from shutting down my computer.

Firefox has stopped working in my computer. I have uninstalled and reinstalled 3 times now, and it will not load up. Many articles online instruct me to clean cookies, etc. but I cannot do anything if the program doesn't load. It does not even show as loaded in my Windows Task Manager. Please advise.

Hello. I am experiencing constant BSOD crashes since Firefox updated to Quantum. It happends shortly after seemingly unrelated actions: opening a link, clicking video to play, or even attempting to close the app. Turning hardware acceleration off didn't solve the problem, although my PC is Sony VAIO laptop with combined Intel/Nvidia graphics which (probably) may complicate things. Resetting Firefox didn't help either. O/s is Windows 7. I also have KAV.

Firefox hangs when I open a new tab or new webpage. It's really annoying!

Everytime I do the automatic updates this shit happens. I used to go to one of the articles where it gave me instructions on how to reset my preferences, but that thread has since been modified, it now says to delete my pref.js, but that doesn't fix the issue anymore.

So i'm resorting to actually making a god damn account and asking why this shit keeps happening. I uninstalled Firefox and re-installed aswell, but it saved some of my data which I kinda need (bookmarks). That doesn't help.

I know that resetting my preferences back to default every update used to fix it, but I forget how now. Thanks...

Can someone just tell me how to fix it so I can update without having to do all this shit again.

I have only one extension and that is adblockerplus. Not likely the cause as it does this aswell without.

Occasionally, any piece of complex software will stop responding, and need to be forcibly shut down. I had such an event today when the right-click (context) menus and title-bar menus wouldn't appear. However, since upgrading to FF 57, I now see about 6 Firefox tasks and 6 firefox.exe processes in the Task Manager (Windows 10).

I like the feature of being able to restart Firefox (after killing it) and have my previous session restored, but the processes aren't really distinguishable in Task Manager, so I don't know which one to end/kill. I had to kill a few of them today before I stumbled upon the "main" process and Firefox disappeared. Can you help me to identify the main process for next time?

Every now and then (maybe once a week on average), Firefox suddenly freezes, and checking 'top' shows that the plugin-container is using 90%+ of both CPU and RAM (I have 12 GB of RAM). So I kill firefox, and when I restart, it is running as normal again.

For extensions, I only have LeechBlock (and Ubuntu Modifications). For plugins I have Flash, Java, OpenH264 Video Codec, and iTunes application detector (apparently). Flash and Java are both up-to-date.

Since the problem happens somewhat rarely, I haven't been able to reproduce it or track down any kind of cause, but I thought it merited reporting anyway; a web search didn't seem to show anyone else reporting the same problem.

For the past few months (it's October 2017) after starting the browser I can open 3 tabs tops before the browser slows down incredibly, things load slower, videos stop and start, ads don't close quickly. Eventually, 3 tabs or more tabs, the whole thing comes to a halt and freezes and I have to restart. I've cleared my history. Doesn't help. I don't know what to do. Thanks for any help.

usually happens playing videos on facebook or clicking on links to dailykos headlines. I have to turn the computer off entirely bypassing the normal shut down proceedure in order to undo the freezing. When I restart the computer it goes back to the freezing place and gets stuck again. There was a brief flash that said a webpage was causing the problem in yellow at the top of the screen; it lasted about 3 sec and then disappeared. after 3 times of trying the normal shut down after restarting my computer required a rather lengthy disc scan (3 indices) where many files were deleted and restored. I would like to continue using firefox but I am confused about why this is happening. What is my computer doing while freezing if indeed it is a webpage that is causing this to happen. I used malwarebytes anti virus and microsoft security essentials scans regularly and use good internet habits. Is this somehow related to the recent Intel invasion? So I just got a message about an installed plugin, Shockwave Flash 28.0 r0. I guess this means I should deactivate it?

Windows 10 and Firefox were running well on my (old) windows 10 Compaq pc. After uninstalling eset nod32 and installing Sophos it ceases to really start up. In task manager I see Firefox somewhere down below, but it does not complete the startup so I do not see the browser opening. Killing the Firefox instance, reinstalling and restarting it without any add-ons (they were https everywhere, bluehell firewall, CSfire, Click&clean , Privacy Badger) does not do the trick  :-(

Can you help (other than unistalling sophos...) ?

Cheers, Wim

If I hit a link in Facebook and it is a YouTube video, Firefox goes unresponsive and I have to open the task manager and close Firefox. This happens even if it opens in a new window. I can't even open YouTube on its own without having this happen, can you tell me why? I do have three links that I have bookmarked that are YouTube videos and they play fine, but nothing else.

The search bar on Amazon.com has stopped suggesting items or autocompleting what it thinks I want to search for. I don't know how this happened but I want it to work again. It was very helpful for searching on Amazon.com. It is only not working for Amazon. This autocomplete option still works on Google and Yahoo, just not Amazon. How do I make it work again?

So I have been using Firefox to watch various videos on my PC for a while, and never had any issues. Earlier in the week I ran into an issue with the picture on the videos I will be watching freezing at a certain point. Usually when this occurs, the sound will continue to run, but the picture on the screen will just stay frozen. And to clarify, it is just the picture in the video that freezes, no issues with Firefox freezing. Also, it is important to note that at times the sound will hop to the end of the video (while the video continues the play at the point it was at), and I have even seen the picture freeze with the sound hopping to the end of the video.

To clarify, when the video picture freezes, there is no way (that I have found at least) to move beyond that point in the video. In essence, the video is useless after this issue pops up: something such as buffering does not solve the issue.

I noticed this issue only after my PC upgraded to Firefox 37.0.1. While I am not 100% certain the issues started after the upgrade, I am fairly certain, as I ran a video in chrome and it worked without any hitches. That led me to believe it is a Firefox issue, hence why I am asking it here. I prefer Firefox to chrome, so I hope someone can help me out in resolving this issue so I can stick with Firefox.

Any remedies?

Thanks in advance for all the help :)

Can I provide any more info to spark some answers? Let me know if I left any gaps that make resolving the issue challenging.

I am using OS El Capitan 10.11.1 and a mac book pro mid 2014. Force Quit does not work. There is the little black dot under the icon showing that FF is open, but if I click it nothing happens. I am literally stuck. I ma o computer whizz kid, so any suggestions/help gratefully received. Thanks

Firefox within the last month has started freezing every time on a Windows 7 laptop every time I try one of the above actions. I have tried "refresh Firefox", safe mode, uninstall/reinstall, nothing seems to help. Can't open prefs so I have not been able to turn off hardware acceleration. However, I was able to set up Firefox Sync which let me get my bookmarks to another PC and it looks like make setting changes on that PC affects this copy of FF so I <think> I've also tried turning off hardware acceleration. Nothing works. Especially frustrating that the options freeze. Firefox has worked for years on the affected laptop, is there anything I can do except give up and switch to another browser?

At first, the same night I decided to update--things were fine but after using the browser hours later a second time: some flash scripts would simply not respond and freeze the tab the content is on or like in my question, constantly stutter. The problem for flash videos only seem to occur when I scroll onto links or when moving up/down a page. I encountered similar problem with FF7--like that time, I installed/uninstalled the flash player and even resetted firefox but to no avail--the problem persisted. It is also present while in safe mode. P.s. such problem is seemingly not present in other browsers which brought me to ask this question for assistance.

hi about 2 days ago ff stopped working. i type an address into the usual window like i've done a million times, hit enter, and nothing happens. i click on a bookmark, the url shows up in the address window, but nothing happens. there are maybe 3 bookmarks that still work, and all the rest are duds. auto-complete still works, but firefox refuses to take to the address. i get a lot of "flash crashes" (thanks, adobe) so i recently updated flash, and that started the problem. this is why i distrust updates. (for the record, i keep current with firefox updates, even though it is still bloatware that uses 2 GB just to run 3 windows. anyway, any help you could offer would be most... helpful! (not sure why my exclamation points are printing as open-brackets, but hey, whatever, that's the internet) thanks, tim
