I have firefox 20.0.1 and Java SE 7 U21 10.21.2.11 Plugin installed..I don't have any older versions of Java installed..I have checked and there are no older java consoles or plugins..
For last couple of day..for any website I open (Facebook.com, Espncricinfo.com, dx.com, even Support.mozilla.org or any mozilla troubleshoot page searched through google).. Firefox hangs..then gives me a popup error window with following message; "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." (message is followed by the path of .js script file..different filename for different site)
I disabled Java plugin from "extentions" , restarted firefox and opened facebook. I expected to open facebook properly and get a "no java installed or enable java" error at the most but instead same thing happened and got the same error message..
Even after disabling Java plugin I am getting same error on all websites... Infact other than opening google and searching I cannot use firefox for any other website.. Even this message I am posting using Opera because firefox wont let me open this page also.. Anyone has any solution?
Try starting FF in safe mode & attempting again
Also if you haven't already run a plugin check to see if all are up to date which you must do manually.
FireFox > Addons > Extensions/Plugins > Check if plugins are updated. Update accordingly.
Reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.
Clear the cache and the cookies from sites that cause problems.
"Clear the Cache":
"Remove Cookies" from sites causing problems:
Thank you guys for the replies.. I did all of the above..and still the problem persists..
I tried opening sites which i had never opened before..and same error.. infact except google..i get this error on all websites..even news.google.com gives me same error.. I am osting this reply using Opera as firefox hangs when I try to open this page and gives me same error..
Strange is I get this error even when java plugin is disabled... I am going to completely uninstall firefox and re-install it..and see what happens..
I have solved this issue..
First of all thanks everyone for suggestions...
Thing is I used to use firefox without any added extensions or add-ons..so my firefox only had plugins/add-ons/extensions installed automatically by programs.. i.e. Flash, Java SE, QuickTime and Foxit Reader plugin..
As previously stated..disabling any or all of thse plugins was not solving the issue.. So I backed up my bookmarks.. I uninstalled firefox... removed all settings and data and profiles...removed any leftover files too...
Then I re-installed firefox using "Run as Administrator" ....
And the issue is solved.... the Flash, QuickTime, Java SE and Reader plugins were automatically enabled after first use...
And I am typing this reply using Firefox only...which was not possible when I had the issue...
I don't know exactly what or why the problem was...but it is solved now..
