My plugin is not working when "out-of-process plugins" ("OOPP") is enabled

Plugin is working fine with FF3.0 but it is not working with FF4.0 and above. The reason I found out is in about:config dom.ipc.enabled is set to true. This means it whitelists the plugins to run in a plugin container.
When I disabled the dom.ipc.plugins.enabled to false, I observed that plugin is working fine.
I also tested by adding a separate entry dom.ipc.plugins.enabled.plugin.so to false and changed dom.ipc.plugins.enabled back to true. still it is working fine.
This plugin is using NPAPIs.
I couldn't figure out why the plugin behavior changes when it is running as a part of FF and running as a separate process.
Thanks in advance for your help.

    The longer this thread continues, the more ancillary comments you throw in that aren't directly pertinent to your problem with your DVR software not working with Firefox 4.0. Sorry, I don't intend to continue with this discussion.
    I do agree that ''something'' needs to be done better with regards to plugins for Firefox, but I do disagree with you as to whose responsibility that ''something'' is.

  • The button on my Ipod Touch (the big one just below the screen) will not work when I press it. Nothing happens, when before it would wake my IPod out of sleep mode, and exit out of programs I was using. Now, no reactions. What should I do?

    The button on my Ipod Touch (the big one just below the screen) will not work when I press it. Nothing happens, when before it would wake my IPod out of sleep mode, and exit out of programs I was using (ex. ITunes or Safari to main screen) . Now, no reactions. When I press the button, it appears to be more indented then it was before. What should I do? Do I need to get it fixed or replaced, or is this a problem I can fix on my own? Whatever it is, I really need some advice. Thanks in advance.

    I just got the iPhone 5. It's completely synced and working.  All my contacts are loaded.  However, caller ID is not working when I receive a call or a text.  Can anyone help me out with this?

    Well, assuming all of the above, Notifications, etc., it just might be time for a visit to the Apple tore genius center for a session with the techs.  See if it is a fault in the hardware or just an iOS reinstall is the answer.
    One more thing you could try, backup so you have a record of content, then restore to factory conditions be an Erase All Contents and Settings.  Then restore from the backup you just made.  That has helped some with WiFi problems, may be it would work with your problems.
    But with that behavior of another app with problems, the geniuses looks like a less stressful thing to do.

    Lots of WIFI needs a username and password to get access. I guess you're lucky and yours is set up unsecured.
    Normal secured WiFi requires only a password to get access. The password is used to encrypt traffic between your device and the WiFi access point. If whatever you are using requires a username as well then it is not simply normal secured WiFi. It might be a subscription WiFi service like GOGO, ATT, etc., or a service with authentication, i.e., college campus, etc. To help you out we need to know what you are using and what connection dialog you are being presented with. You don't have exactly the same problem as the original poster. He is having a problem entering a password into the password dialog that iOS presents when one tries to connect to a normal secured WiFi network. Could you clarify exactly which WiFi service you are using.

  • HT1430 For some unknown reason my Apple ID password does not work when trying to down load books from the IBook or Nook Apps.  It also has stop work when trying to down load new Apps.  Any suggestions out their???

    For some unknown reason, my Apple ID Password does not work when trying to down load IBooks, Nook books, or new Apps.  Everything else seems to work.  Any suggestions out their???

    I appreciate the info and realize that the Nook App is not related to my Apple account but this too has stopped working.  My situation first started with the Nook App not down loading and then has now spread to my IBook and new app downloads.  I have checked into my ITunes account and the ID and password are correct  and at times when I am asked to submit my Apple password such as setting up this Apple Support Community the ID and password work.  My problem seems to be just with trying to use my ID and password when wanting to download new books or apps.  I can go into the IBook, Nook, and App stores and seemingly download an item but when clicking on the new book or app nothing happens and I get a message that states it can not get into the ITunes store and it wants me to either try again or cancel.  This message appears usually ten minutes after I have tried to make a purchase.  At other times when I attempt to download a book or app I lose the screen and the IPad goes into the opening screen.  Short of redoing my Apple account or deleting an app and attempting to reload the app (but this won't work because the App store won't load new apps) I don't have a clue what to do.

  • Hyperlinks to pdf files not working when project is exported out as SWF and uploaded to server

    hI all
    I'm using CS5 and i have hyperlinks to pdf files in my indesign project. However when i export to SWF, although the links work locally, they do not work when i upload all the relevant folders and files and test it from a server the links to the pdfs can not be found, the error messages indicates its looking for the files on my hard drive. I have also noticed that if i copy all the relevant folders and files and exported swf to a different directory and then launch swf from there the links do not work there either.
    Other than seperately uploading each pdf indvidually on to the server and then creating a hyperlink to it from the local indesign project i don't know what else to do.
    Any advice much appreciated.

    I have your same problem, but didn't consider uploading the PDFs and then linking to them. I'm willing to try it. Let me know if you ever found a better way, ok?
    Thanks.

    That error shows up when a phone is jailbroken or you are trying to downgrade the iOS version. Neither of which is supported by apple.

  • The touch screen is not working when I am in the Music app of my iPod Touch.  How do I get it to begin working?  It just stopped today.

    The touch screen is not working when I am in the Music app of my iPod Touch.  How do I get it to begin working?  It just stopped today.
    Does anyone know what I can do?  I am unable to switch screens, and I can not see the track that is playing.  The only was I can switch between songs is to use the controls on my headphones.

    Try the stamdard fixes to rule out a software problem:
    - Reset. Nothing will be lost
    Reset iPod touch:  Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Restore from backup
    - Restore to factory defaults/new iPod.

    My iPhone volume is not working when I have the volume set on. It will work with the headphones but other then that nothing. What's going on with it?

    supposedly from what I have read it is a software issue. I actually am also having this problem it worked after I performed a full reset,  but now it has started again tomorrow I am going to the apple store to find out what I can do as I bought my 4s right before the 5 was released.

  • I was running KeyPassFox with Firefox 8.0.1, but the plugin does not work in the new release (9) . Is there a way to restore my previous version with all of my bookmarks intact? I do not mind if I have to restore the plugins myself.

    I was running KeyPassFox with Firefox 8.0.1, but the plugin does not work in the new release (9) . Is there a way to restore my previous version with all of my bookmarks intact? I do not mind if I have to restore the plugins myself.
    The plugin shows on the list as enabled and functioning, yet the tool does not show on the toolbar. It would appear that I need to restore the previous version of Firefox and wait until a newer release of the plugin is available before upgrading the browser.

    I copied the iTunes file from the external drive and it's in both places.  I thought all I would need is the iTunes program (which I downloaded to new computer) and my iTunes library file.  There must be something else that's missing.  My iTunes library looks the same on the new computer as it does when I open it on the external drive.  If I click on an iTunes library song from my new computer, it will only play if I have the external drive plugged in.
    My back-up drive is a mess.  I have multiple copies of music, video, photo, and document files and I don't know how that happened. ={  Obviously, I don't know how to back up stuff properly and there are back-up files extending over a 6- to 8-year period.  I think all I did was just drag and drop the main folders from the back-up drive to the same main folders on the C: drive.  Also (and I'm kind of fuzzy on this) Windows used to automatically save music files in a folder within my document files (which makes no sense to me).  As my Jewish friends would say, "Oy Vey!" 

  • Why my i pod is not working with out charger

    hey, my i pod is not working with out the charger plugged into it?!

    What do you mean? Please be more precised so I may help you father. If it is plugged in, but won't open. You must wait at least 5 minutes before using it again. Ipod need a certain amount of power for it to start. Or even when its plugged in but wont charge, make sure it is connected very well to the computer or the power outlet to the Ipod. Lastly, if you are charging at another place, for example in your friend's house. The voltage power may be different from where you mostly charge it from. But if it isn't plugged. Maybe it need to be charged?
    Hope this helps.

  • Help! Javascript not working when object moved from one page to another!

    Hello all:
    I am new to Adobe Livecycle Designer (version 8.0). I have created a 3 page interactive pdf form with numerous objects (text fields, radio buttons, drop-down boxes, etc.), that our business wants to begin using soon.
    I am having difficulty with some of my Javascript not working with a few of my objects on page 2 of the form. Specifically, there is a drop-down box for "Country" on page 2 of my form. When the user selects, for example, "United States" from the list, I have Javascript that is supposed to change the "Currency" drop-down box rawValue to "US Dollars" accordingly (upon the change event).
    I think my Javascript syntax is proper, but I am not certain. Here is my simple Javascript associated with the "Country" drop-down box (Note: rawValue 80 = "United States" and rawValue 105 = "US Dollars"):
    form1.Page1.cmbContactInfoCountry::change: - (JavaScript, client) -
    if (this.rawValue == 80) {     
         cmbCurrency.rawValue = 105;
    This seems pretty straight forward and it WORKS when my "Country" drop-down box is moved to page 1 of the form, but it WILL NOT WORK when I move the "Country" drop-down box back to page 2 of the form (which is where it belongs).
    Does anyone have any suggestions or solutions? I have spent probably 6-8 hours racking my brain trying to figure out why it works when on one page, but it does not work when move to a different page. I am guessing that I may have corrupted something OR that I am not fully addressing the proper name of the object?
    Please help!
    Frustrated and helpless near Chicago!

    Hi Jono:
    Thank you for your quick reply.I was able to obtain the full name of the cmbCurrency object using the method you taught me. That is brilliant! Great short-cut tool.
    Unfortunately, I am still having issues with getting Javasript for the cmbCountry object to work with the cmbCurrency object. I haved pasted my new Javascript below.
    JavaScript for cmbCountry object:
    //UNITED STATES
    if (this.rawValue == 1) {
              xfa.resolveNode("form1.#subform[1].cmbCurrency").rawValue = 1;
    else
    //CANADA
    if (this.rawValue == 2) {
              xfa.resolveNode("form1.#subform[1].cmbCurrency").rawValue = 2;
    I have checked the "Specify Item Values" checkbox of the cmbCurrency drop-down object and Value 1 = "US Dollars" and Value 2 = "Canadian Dollars".
    When I select "Canada" from the cmbCountry drop-down object, the rawValue of the cmbCurrency drop-down object is changed to "US Dollars" (when it is clearly defined as "Canadian Dollars"). When I select "United States" from the cmbCountry drop-down object, the rawValue of the cmbCurrency drop-down object stays blank for uknown reasons. Very strange.
    Since I am not able to further explain in detail on what I am experiencing, I have posted a link to my file below (I just signed up for an account at ShareFile). I would forever be indebted to you if you can help me figure this out!
