Keep receiving "Script Errors" on various websits

Hello everyone,

I do not know if this is the right place for this problem or not, if it is NOT then could one of the Moderators please move it.

My problem I am posting about is: I get Script Errors on various websites. It does NOT happen all the time, but when it does happen it raises all kinds of havoc with my computer!  For example just a few minutes ago I was trying to read an article on www.grit.com  after I clicked from an email I received. The webpage I was on when it began:

http://www.grit.com/community/travel/camping-equipment-zm0z15jazreg.aspx?PageId=2#ArticleContent

I was on page 2 of the article and was scrolling down to read further when I started to receive the script error message. I clicked to stop the script. I started to read further down the page again, I again received the script error message. I again clicked to stop the script! I then went to click to go to the next page and I again received the same script  error message! I again clicked to stop the script!! This time it froze my web browser! I tried to click a check mark for "Do not ask again" and clicked stop script! It froze the webpage! and my web-browser! I tried to click "debug script" and that froze my computer for a few seconds! SO I clicked: Ctrl +Alt+Delete it took about a minute to bring up the screen, I then clicked "cancel". I tried to close the web-browser but was unable to! I tried closing the web-page I was on and was unable to! I even tried to close the other Tabs that were open and was unable to! So I was forced to restart my computer! 

This has been going on for a while. It affects several websites at various times. It happens when I am on Yahoo.com fantasy sports pages, it happens when I click on news articles on my Yahoo.com home page, even happens when I click on a news article or story on MSN/Hotmail home page, click on a news article on my AOL home page, occasionally it will happen on Facebook ESPN.com fantasy sports, and other webpages.

Java is up to date, Adobe is up to date, and all of my programs are up to date!  The only thing that I can think of that might be causing this is an "add on" in Firefox that has been disabled due to vulnerability issues. that add on is: Java Deployment Toolkit 8.0.910.14 version 11.91.2.14

Here is the webpage on Firefox about the add-on:

Can anyone help me figure out why I keep getting these "Script Errors" and why they keep freezing my Web-Browser and my computer and how to fix it?

I'm fishing here, does your Firefox have NoScript and other security extensions, plugins, etc.? 

Sorry I am very late in responding to you, but for some reason I did not get a notice that someone had responded to my topic!

From what I can see in my Firefox "add-on manager" NoScript and other Security extensions, etc. are not listed, just the usual plugins. I would post a screenshot, but not sure how to post it so you can see it.

I am still getting script errors on various websites. Just wondering if it could be related to Windows No longer going to support Vista in early 2017 and some companies no longer offer support for their programs that operate on Vista! Also some programs/add-ons are no longer getting updated because of this.

Are you getting the script errors if running Firefox without add-ons (Safe Mode)?

No I did not get any script errors while in Safe mode. At least none that I noticed.  However while on Microsoft's user support forum for Outlook because I was having major problems since their new "update" because My Firefox Web Browser constantly kept freezing and giving me "script error" message; where  the URL or website/webpage address is listed!   I saw someone suggest about: open the menu tab in Firefox, then click "options", then click on "advanced", then uncheck the box: "use hardware acceleration when available", then restart Firefox. That has helped a LOT!!  So far I have only gotten a couple of script errors: one on one website and it did not return and one on another website and it did not return, when normally I would have gotten a lot more! And over the past 2 days I have gotten hundreds if not a thousand because of the New Updated Outlook email.  So hopefully that has fixed one of the causes of the script errors! Whether or not it is "THE" Fix or not, that is yet to be seen. 

I will keep a watch for any changes and see if the script errors return or get worse again.

If there aren't any script errors in Firefox safe mode, you might need to isolate the add-on causing the errors. Try disabling one add-on at the time, until you don't get the errors anymore.

I think I have an idea which one it might be:  Java Development Toolkit  8.0.1010.13  NPRuntime Script Plug-in Library for Java™ Deploy

Firefox has it "Disabled": Java Development Toolkit 8.0.1010.13 Is known to be vulnerable. Use with caution.   According to Firefox it was Blocked on July 18, 2013

But when I clicked on  "More" for more details it gives the version # 11.101.2.13  and said it was last updated on Friday, August 12, 2016

I used to have it as: "Ask to Activate"  but Yesterday/Last night changed it to: "Never Activate". Whether that has an affect or not along with unchecking the box: "use hardware acceleration when available" I will see.


The only other one I think might be a contributor to the problem is: Adobe Acrobat   Adobe PDF Plug-In for Firefox and Netscape 11.0.10

Again when I click on: "More" for more details Firefox says: "Adobe Acrobat is known to be vulnerable and should be updated."   It also gives the version # as: 11.0.10.32 and last updated on: Wednesday December 03, 2014. I have that as: "Ask to Activate"  I have tried to update it but I am unable to because I have Windows Vista and the current version of Adobe Acrobat which is Adobe Acrobat DC requires at a minimum: Windows 7.  

There were no extensions that were installed, until just recently about a few weeks ago and that is "Empty Cache Button". I installed that because I was having problems fully clearing the cache in my Firefox web browser and someone recommended that on the Firefox community help forum website.  But the Script errors started happening well before that and the Firefox web browser got WAY worse after the Outlook Email update took affect.

The only other thing I think might be a cause is with the age of my computer 9 years old, there are a lot of remnants of files left from programs that have been uninstalled, deleted, updated, etc..  Especially from Java and then uninstall old versions of it after installing the latest version/update. Could uninstalling older versions of Java/java plugin after installing the Latest updates, could that cause this type of problem, causing script errors?     Java recommends uninstalling older versions when installing the latest updates because the newest updates cover the older versions, but they also state that some websites or webpages may experience some video problems when doing so. But I have never had any problems.

Hello.

Check this link https://support.microsoft.com/en-us/kb/308260

I mainly use Firefox for my web browser and will also use Google Chrome as my secondary Web Browser and I barely ever use Internet Explorer.  Here is how I use them:

I use Google Chrome to check: my one Yahoo.com email account, a Hotmail.com  email account I have set up for my dad, and my AOL.com email account.  I use the Yahoo.com account to play some fantasy sports. And I will maybe do a couple of searches using Google search or Bing.com.

I use Firefox: To check my main Yahoo email account, my Hotmail.com email account, also to check my AOL email account, do social networking, web surfing, Search using Bing.com, etc.

I only use Internet Explorer to check my mom's Yahoo.com account and that is occasionally. Maybe once a month or once every 2 or 3 months. 

Other things I do: Clear my web-browser cache every day sometimes multiple times a day, Clear my computer cache about once a week, clear my cookies at least once a month, defrag my hard drive once a month to about every 45 days or so, scan my computer for viruses and malware at least once a week; more if something weird starts to happen or gets picked up, and I always update all of the programs that I am able to update.

"...Clear my web-browser cache every day sometimes multiple times a day,.."

Clearing once daily is probably adequate    I clear mine normally just once daily.

I went to read an article on AOL.com and I got the script error again and I clicked on "Stop the Script" and then "okay" to continue. But I got the script error again. I clicked on "Stop the Script" and clicked "Okay" again. I did this about 10 times before I got fed up and then clicked on "Do not ask again" and Clicked on "Stop the Script" and this time it Completely froze the Web Browser like it did in my one post above!!   But this time I before that I had clicked "Debug" and took a couple screen shots and was attempting to take a third when the web-browser froze up!  I figured If I showed the "debug" information screen that might lead to what it causing this to happen!

How can I include those screenshots?
