Question

Firefox

Jun 10, 2016 9:08PM PDT

Firefox has been crashing several times a day saying a script on this page maybe busy then hangs up.
It gives a choice of Continue, debug or stop. Can't do anything from there. Have to shutdown firefox in task manager and processes.
Have all add ones turned off and have the latest version of Firefox.
At times I will click on the Firefox icon and it will say Firefox is already running. Have to do the task manager routine again.
Any suggestions would be appreciated.

Corrupt data files is my guess
Jun 10, 2016 9:54PM PDT

Step 1
Refresh firefox by clicking on help then troubleshooting information, refresh

If that does not fix it, uninstall firefox after backing up your bookmarks and important data, then do a fresh install, sometimes the updates corrupt a file somewhere and a fresh install is the only solution, other times the refresh will fix it.

Thank you.

I have removed and re-installed the program three times.
It works fine for a few hours then starts hanging up again.
I am using Windows 7 Home premium.
The thing that is very puzzling is, when there is nothing on the screen, it says it's already running. It does show that it is running when I go into task manager and processes.
Also have done system restore to the earliest date I can.

How are you protecting your PC?
Jun 11, 2016 7:51AM PDT

Here I find that unless I add a few things I might get script issues.

My choice today is W10's Defender and for the browser I add Adblock+ and Web Of Trust.

Yes, WOT is not an antivirus or such but if I was to go to a bad link I get warned and will bail out.
There are web articles about how Adblock+ has been blocking bad things.

Also, is the machine free from malware? I use Grif's advice from http://www.cnet.com/forums/discussions/how-to-remove-pup-option-603542/#post-f742c795-5881-433b-a29b-6d758efe5cd3 to know what to scan with.

Comcasts Norton 360
Jun 11, 2016 9:00AM PDT

I was starting to wonder about the Norton causing the problem.
My computer has a i7 processor with a Samsung SSD and is really fast until I get online.
My next step will be to remove Norton and see if that helps.
I had thought about upgrading to Windows 10 before the freebee runs out, but have a couple programs I use a lot and don't want to take the chance.
Thanks Bob

Norton and script issues are on the web.
Jun 11, 2016 9:05AM PDT

It's partly why I don't use their web addons.

I have Comcast too
Jun 11, 2016 9:12AM PDT

and used their free Norton offer at first than I discovered that Norton was indeed a source of my problems such as the ones that you're describing.

Couldn't load some pages, sometimes even getting booted of of the internet.
I switched to Avast than any everything was fine.

Since than, I have moved the computers to Win 10 and I'm very happy just using Windows Defender as my anti virus program .

If you decide get rid of Norton, be sure to use the Norton Removal Tool
Do not click on reinstall Norton

Not Norton.
Jun 11, 2016 3:09PM PDT

Removed Norton with the removal tool and still have the problem, just using defender.
Router is out of the mix and swapped the 6190 modem with a 6183 my neighbor had, still the same problem. Just to be sure, changed the on-board NIC to a Intel 10/100/100 card and still the problem so will be calling Comcast back.
The guy I talked today with Comcast saw a lot of errors in the last 10 days which about when the trouble started.
See what they have to say.

Answer
did you try another browser
Jun 11, 2016 3:54PM PDT

did you try another browser to see if it is a browser issue? did you try disabling addons and toolbars in firefox to see if one of them is causing the problem?

Yes, Firefox,IE 11 and Chrome.
Jun 11, 2016 6:28PM PDT

I have tried all 3 with the same results.
Had all ad-ons disabled.
After talking to a Comcast tech who actually spoke English as a 1st language and knew what he was doing, they are sure there is a problem with my connection in their hardware. He said it could be something as simple as a bad tap to a problem in their node.
Whatever it is, I know it will be looked at.
Thank you all for your input, it definitely gave me a starting point.
