other applications will not start under firefox

Since FF10 was installed on my Win7 64 bit system, none of the applications that used to be able to launch firefox can do. 2 include sylpheed (who is preparing to launch the default browser) and rssowl (set in the same way).

Why?

Are you sure that Firefox is always set as default browser?

https://support.Mozilla.org/en-us/KB/how%20To%20make%20firefox%20The%20default%20browser

If it looks good, try IE by default and then reset Firefox as a default. Sometimes Windows will need a foot to know who's in charge.

  • URL clicked in other programs will not load in Firefox

    Only in the last weeks of 1-3 (?) or so, I find that I can not click on links in other programs and have load URL in Firefox, which is my default browser. They always used to load perfectly and move me to the new tab in FF, but now they do not have.

    At first I tried to disable some recent FF modules one at a time to see if one of them could have been the problem, but that does not resolve, even though I may have missed one. Yet, I can't imagine how an independent add-on could cause URLs do not load from other programs. I tried to load the URL by clicking on it in Thunderbird, WordPad, MailWasher Pro and free agency, but each of them either just trembled at the screen for a moment and then stopped, or gave me a message such as 'WordPad could not open the URL' or ' there was a problem sending a command to the program "(free agency). However, when I copy and paste these URLS even in FF and press ENTER, these sites load perfectly.

    I may be wrong in the present, but it seems that something has changed in the FF that now prevents the links clicked in other programs from loading. My only other thought at the moment, it's that this peut eventually began all the time I upgraded from FF 10.0.2 to FF 11.0.1, but I have no evidence to support this theory.

    It's really an annoying problem and embarrassing, so any help to solve it will be much appreciated!

    Thank you
    Al

    The problem is solved now, as a result of assistance that I'm on WindowsSecrets forum. Once I realized that the problem occurred only with PCM and Thunderbird, but with other programs as well (I tried WordPad and free agency, which didn't even load the URL in Firefox), I posted the question on other forums, trying to see if others knew something about this issue. I got the answer of a member of the forum on this page:

       http://windowssecrets.com/forums/showthread.php/145441-URLs-clicked-in-other-programs-won-t-load-in-Firefox?p=847784#post847784
    

    In case you are not a member it or may not load this page, here is her suggestion:

       With FF closed type %APPDATA%\Mozilla\Firefox\Profiles\ in the start menu search box, click the item that appears and delete localstore.rdf FF will replace it on starting.
    

    I did this and all four programs that had previous problems loading of the URL, including MWC, now load them perfectly. The only (small) problem with this solution was localstore.rdf apparently saves all information about things like the Firefox toolbars and their customization, so all that was lost when I deleted the file, but I re-adapted quite quickly and everything is fine. Any thoughts about what localstore.rdf does, why this problem happened, or how to do to prevent it happening again will be appreciated.

    I hope this info helps. Thanks again for your help.

    Hello Roberto,

    Please try to run the software as administrator, right click on the Photoshop program in the start menu, click on properties and you will be that Photoshop has an option with a run as administrator check box. Click on the check box, and then restart the software.

    If that doesn't work then turn on the hidden admin and try to run it, please see the steps to enable and disable http://www.howtogeek.com/howto/windows-vista/enable-the-hidden-administrator-account-on-wi ndows-vista /

  • Critical error in QML, module 'bb.data' is not installed, the application will not start

    Hello

    I'm trying to do something similar to the example here:

    https://developer.BlackBerry.com/Cascades/reference/bb__data__xmldataaccess.html

    I learned to expect problems with the QML preview, but this error occurs when you try to launch the application on my device of DevAlpha!  The exact errors are:

    Critical: bb::cascades::QmlDocument: error when loading QML from:   QUrl( "file:///apps/com.example.rim/native/assets//main.qml" )
    Critical:   --- errors:  (file:///apps/com.example.rim/native/assets//main.qml:3:1: module "bb.data" is not installed
        import bb.data 1.0
        ^)
    Critical: bb::cascades::QmlDocument:createRootObject document is not loaded or has errors, can't create root
    

    Note that I added the lbbdata - for the LIBS in my .pro file, so there should be no reason why the app cannont find bb.data!  Has anyone else seen this problem or found a solution?  It is essentially blocking any progress on my app!

    Thank you

    Nick

    try to including this line in your hand:

    BB::data:ataSource::registerQmlTypes();

    the notes say that this has been deprecated in version gold but it doesn't seem to be the case... I created a new project using the sdk of gold and had the same problem you did if I used a data source class above the fixed line!

  • The FireFox 42.0.1 application does not start.

    The FireFox 42.0.1 application does not start. I can uninstall and reload FireFox 37.0.2 and that worked, but now when I load 37.0.1 it installs really 42.0.1 that no longer works.
    I had to use IE 10 to contact Mozilla.
    Year annual should be ashamed of this...
    Can you tell me why Mozilla FireFox 42.0.1 installs but won't work?
    In addition, why FireFox 42.0.1 install when I try to install 37.0.2?

    It is possible that your firewall or other security software blocks or limit Firefox or plugin-container process without informing you, possibly after the detection of changes (update) for the Firefox program.

    Delete all rules for Firefox and the plugin-container in the permissions list in the firewall and allow your firewall to ask permission to get access full and unrestricted, again to install for Firefox and the plugin-container and the update process.
