When I open Add-ons, from the Tools menu, I get an unresponsive script error: file:///C:/Program%20Files/Mozilla%20Firefox/components/nsExtensionManager.js:623.

When I try to click on Add-ons, from the Tools menu, I get this error message of an unresponsive script: file:///C:/Program%20Files/Mozilla%20Firefox/components/nsExtensionManager.js:623. This is to say the least about the unresponsive script errors at other times. However, at all times, it won't go away - even by clicking on the 'stop script' option; even with checking the 'don't ask again' option. I've cleared the cookies and history as best I could, but it appears that there is some sort of conflict. How can I resolve this? Kevin: [email protected] Thank you.

This is typically caused by a problem with the Personas Plus 1.6 add-on and it conflicting with the Google toolbar.
Try disabling the Personas Plus add-on. To do this open the add-ons manager by selecting the Tools menu, then Add-ons. In the list of installed extensions click on Personas Plus, then click on either disable or uninstall.
If you can not access the add-ons manager, follow the instructions in the [[safe mode]] article to start Firefox in safe mode. You should then be able to disable or uninstall Personas Plus. You can find more information on this procedure in the [[Troubleshooting extensions and themes]] article.

  • I get a box that says a script is not working. The name of the script is file:///C: /Program%20files/Mozilla%20Firefox/components/nsBlocklistService.js:648 This is getting worse and more frequent. What can I do?

    This box pops up more and more frequently, and sometimes completely ties up my computer.
    If I knew any more to tell you, I could probably fix it myself!

    In Firefox Options / Privacy be sure "Remember download history" is checked. To see all of the options on that panel, "Firefox will" must be set to "Use custom settings for history".

    Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
    '''Note:''' You might want to print these steps or view them in another browser.
    #Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
    #After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
    #Delete the Firefox installation folder, which is located in one of these locations, by default:
    #*'''Windows:'''
    #**C:\Program Files\Mozilla Firefox
    #**C:\Program Files (x86)\Mozilla Firefox
    #*'''Mac:''' Delete Firefox from the Applications folder.
    #*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
    #Now, go ahead and reinstall Firefox:
    ##Double-click the downloaded installation file and go through the steps of the installation wizard.
    ##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
    Please report back to see if this helped you!

  • Ater installing Personas 1.6, Add-ons in the Tools drop-down box is unresponsive

    I have the Brand Thunder custom browser installed and after installing Personas 1.6 I noticed that instead of showing 1 Large boom it shows 2 small booms. In an effort to sort the problem I thought I would try removing the add-on, however clicking on Add-ons causes nothing to happen.
    In the background I have no script running and this keep appearing:
    Script: file:///C:/Program%20Files/Mozilla%20Firefox/components/nsExtensionManager.js:623
    Pressing continue causes Firefox to hang and pressing stop script doesn't work as it just comes back again.

    After manually deleting the personas folder from my profile everything is now fine, I'm not sure which add-on was the cause of the problem but I'll stick with my Looking For Group theme.

  • Why is the word count different when I use word count from the tools menu to the number at the bottom of my mac word document

    Why is the word count different when I use word count from the tools menu to the number at the bottom of my mac word document

    This forum is for Apple's defunct office suite 'AppleWorks' - since the word count is not in the places you mention I assume you are talking about Microsoft Word? Though it's just possible someone in this forum might also use Word and know the answer, you would stand a higher chance of getting an answer in Microsoft's own forums. You could also try asking in the forum applicable to your operating system - Lion, Mavericks or whatever - on the reasonably chance of finding someone familiar with Word.

  • I'm running Firefox 3.6.10 on Windows 7. For several days now I cannot access the "Add-ons" in the Tools menu. Any help would be much appreciated. Thanks, Charles

    Every time I try to access Add-ons, Firefox freezes and I get an "unresponsive script" warning that states, "A script on this page may be busy, or it may have stopped responding . . ." The script in question is nsExtensionManager.js:623. I reinstalled Firefox, but that didn't help.
    Thanks, Charles

    This issue can be caused by the Personas 1.6.0 extension. If you have it then update to Personas 1.6.1

  • I keep getting script errors regardless of the FF version I'm running. This time it's on 3.6 and the error is Script: file:///C:/Program%20Files/Mozilla%20Firefox/modules/utils.js:1027

    I had to downgrade from ver. 4.0 back to 3.6 for my job. This version is the only on compatible with their add-ons and it gives me script errors at least twice a day. The only add-ons I'm running are for work and others who do this job don't have this problem. Using 4.0 I did experience it less often but it wasn't completely cured.

    This is typically caused by a problem with the Personas Plus 1.6 add-on and it conflicting with the Google toolbar.
    Try disabling the Personas Plus add-on. To do this open the add-ons manager by selecting the Tools menu, then Add-ons. In the list of installed extensions click on Personas Plus, then click on either disable or uninstall.
    If you can not access the add-ons manager, follow the instructions in the [[safe mode]] article to start Firefox in safe mode. You should then be able to disable or uninstall Personas Plus.

  • When I try to search from the address bar I get: jar:file:///C:/Program%20Files/Mozilla%20Firefox/omni.jar!/chrome/en-US/locale/browser-region/region.propertieswhatthehell What can I do to solve this problem?

    I don't know when this started but I can't seem to remedy it. I've updated several times but have not uninstall/reinstalled FF. I'd like to do that only if I have to because I'd like to keep my saved info if possible. I'm not computer illiterate but I'm not a tech either so I need fairly basic instructions if it's at all possible.
