Can't Run Javascript on FF 3.6.17 OSX10.6.7

[vienna01]

SOLVED SEE LAST POST

Firefox 3.6.17
OSX 10.6.7
Safari javascript OK
Firefox on Windows 7 OK
When I click on any button that executes a javascript nothing happens on ANY page.

Firefox Preferences Content "Enable Javascript" is CHECKED.
I tested JAVA on this page OK
http://www.java.com/en/download/testjava.jsp
I have latest javascript plug in for Firefox

The web site maintainers say they DO NOT HAVE THIS PROBLEM WITH OTHER MAC + FF 3.6 USERS.
Don;t know what to try next.???

Java and JavaScript have nothing to do with each other. Java is a programming language developed by Sun Microsystems and is now owned by Oracle. The scripting language JavaScript shipped first as LiveScript as part of Netscape Navigator 2.0. It was standardized by the ECMA as ECMAScript. When Java appeared to be "the next big thing," LiveScript's name was changed to JavaScript.

I would ask you to repeat your request, but clarify it. Leave out references to Java and to Windows. Also leave out references to computers that don't have a problem because most computers on Earth have no problem at all with JavaScript.

Just to add on to MisterMe's info - running a Java test page tells you absolutely nothing about javascript on your system, as java and javascript are not related to each other, except by name.

Does javascript work in FireFox if you try a different user account on your Mac?

I just logged on as Guest and FF 3.6.17 was OK with Javascript.
This is first time I ever used another account.
Looks like I have to create another instantiation of Firefox and slowly add in the plug-ins etc. & test for javascript each time.
Is there away that I can build another install of Firefox without overwriting the current one? If not I think I know how to backup everything in FF.

Do you have any suggestion for my next steps other than build a FF from scratch?

Thanks ever so much. I now have a way to debug the problem.

No need to do that (I wouldn't know how to tell you to do that anyway...)
Logging in to another user essentially does that - as Firefox builds its profile. You would notice that you didn't have any bookmarks or other addons that you might have created or installed in your main user.
If you log in to your main user, then (before trying Firefox) open your Home folder, then your Library. Open Application Support, then the FireFox folder. Open the Profiles folder, then the strangely named folder that you find there. Now, you will see a long list of items that are part of your FireFox profile. For most folks, the important item is the 'bookmarks.html' file, and you can trash everything else, I expect. Then, most of that will be created fresh the next time you launch FireFox. Likely will also fix your javascript errors.
By the way, the 'Guest' account is not really what I would consider "another account". It's for one time use (for a guest), and logging out of guest deletes any files and settings that the 'guest' uses.
If you have added any addons or extensions to FireFox, you would then need to add them again, most likely.

That sounds like a plan. I think that will remove all my plugins and addons. As I said, I will then have to slowly add them back & test. Let you know how it goes.

First I disabled each add on and tested. Did not fix problem.
I then saved all my firefox bookmarks in the profiles AND on my desktop using the FF backup tool for bookmarks.
I deleted the profiles [ones with mixed numbers & letters] BUT I left in the Bookmarks section.
I restarted Firefox
At that point I did not have bookmarks or addons I was surprised that no markmarks were there even though I left in that profile section.
BUT I did have ALL the plugins from before. Surprised they were there
I tested-OK
I restored bookmarks & tested-OK Restoring over wrote the saved bookmarks onto the profile.
I added each previous add-on & tested each -OK Restarted FF after every few add-ons.
I was unable to add 2 previous add-ons because they were invalid for 3.6.17 on MAC. They were Colorful tabs & IE TAB2. Wonder how they were installed before?
I also could not find the addon "Keychain Service Integration" on the Firefox addon site. This seemed to be very useful.

Javascript now works on the test site [the real site where I discovered the problem]


BIG BIG THANKS
