I get an error "unable to load XPCOM. I know that I can reinstall Firefox but how to save my favorites?

I get an error "unable to load XPCOM. I know that I can reinstall Firefox, but when I went to do that he erased all my favorites that I did a system restore. How to backup my bookmarks?

Do a clean reinstall and delete the program folder before Firefox to (re) install a new copy of the current version of Firefox.

If possible to uninstall your current version of Firefox to clean the Windows registry and settings in the security software.

  • Do NOT remove the "personal data" when you uninstall your current version of Firefox, because this will remove all profile folders and you lose personal data such as bookmarks and passwords including data profiles created by other versions of Firefox.

Delete the program folder Firefox before installing newly downloaded copy of the Firefox installer.

  • (32-bit Windows) "C:\Program Files\Mozilla Firefox\"
  • (Windows 64 bit) "C:\Program Files (x 86) \Mozilla.

Your bookmarks and other personal data are stored in the Firefox profile folder and will not be affected by a uninstall and (re) install, but do NOT delete personal data when you uninstall Firefox which removes all Firefox profile folders and you lose your data.

If you keep problems also create a new profile.

  • Get message unable to load XPCOM trying to start applications

    Original title: unable to load XPCOM

    I get the message "Unable to load XPCOM" on several applications and they launch.  Couldn't find anything on this site to help on this.  Anyone know the fix?

    Hello

    Thanks to join Microsoft Community where you will find all the required information on the Windows operating systems!

    You get message unable to load XPCOM trying to run some applications.

    XPCOM is Mozilla-related.

    To work with the issue, I suggest to uninstall Mozilla Firefox and check if the problem persists.

    To uninstall a program:

    a. press the Windows key + W

    b. now, select applications if it is not selected

    Hit and c. Type appwiz.cpl enter and uninstall the program from the list.

    If the issue is not persistent, then to work with the issue, I suggest you to post a query in the Mozilla support forum.

  • Error "Unable to load image" with iphone app of Lightroom

    I just downloaded the app and when I click on for my camera to import photos from my new collection "iPhone", I get an error "unable to load image". Someone else has had this problem and know how to fix? I could get a single photo to finally take as if by magic, but other 835 photos give this error when I try and select them. Thanks for your help!

    Hi Ryan,

    I have a few questions to understand the question.

    This happens to all your property or only some?

    Does it occur only on a single device (if you have several), what device you are on by knowing this?

    Have you managed to import all of your camera.

    You take the images of a specific album? If so, can you tell us a little of the assets inside the album?

    It helps to look at this image from the Photos app and a new attempt to import?

    Thank you

  • I can't reinstall firefox, I get the error 'Could not load profile' and not a solution I found works. / Appdata/roaming/mozilla folder is not accessible.

    I'm on Win7 64 bit. Initially, I uninstalled because a program has changed my page of the new tab to something unwanted and I literally had no way to change this back. Now, every time I reinstall, I get the error "cannot load the profile, it may be missing or unreachable", and I can't create a new profile. Whenever I try to any method of opening the profile editor, I get the error 'Could not load profile' then too. I can't access the folder in/appdata/roaming/mozilla at all. It is said it is accessable and access is denied, and tries to remove it tells me I have not permission (even if I'm the admin). No other difficulty I saw worked. Can someone help, please?

    I have done a virus scan, cleaned up one piece of adware, rebooted, and it worked all of a sudden. I don't know what exactly caused to start working, but he did, so I consider this issue closed.

  • Windows 8 mail, Gmail error unable to connect. Make sure that the information you entered is correct

    I tried to set up a Gmail on windows mail 8 for some time. It worked before but then I had to re - install the app and I can't seem to log in now. The only difference between now and when it worked is that I had turned on google + once I had it working the first time, but now I have that turned off.

    I always get this error: unable to connect. Make sure that the information you entered is correct.

    Please always post the URL of your feed, not its content. I'm assuming that your workflow is the one mentioned in the tag "atom: link".

    http://psychicreform.com/mosports/mosports.XML

    Feed validators are complaining that this line contains a prefix of "independent". I think it's probably because in the second line, "rss.xlmns" it does not mention "atom", only "itunes" - the URL in this line indicates the feed reader RSS how to interpret the tags for this application. Without link for 'atom', the tag is meaningless to readers, and it is marked as an XML error, which is enough to cause the feed unreadable. There is no need to have this line (Atom is a very old RSS reader which I doubt anyone uses now) and you'd better remove that line altogether, either that or somehow insert the URL of the atom, which seems to be "xmlns:atom ="http://www.w3.org/2005/Atom"" so that the second line would read as follows: "

  • I get the error message "security log is full, only an administrator can log in to solve the problem."

    On a windows machine XP after putting in place the machine administrator and when trying to connect as a user, I get the error message "security log is full, only an administrator can log in to solve the problem." I know how to solve this problem by going to the event viewer, by selecting the security log and by setting the journal to "ignore the events as needed", but I would like to create a script that will do this automatically for me.

    so far my research revealed that the value of the registry key [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Security] "MaxSize" controls this setting and changing the value default DWORD_VALUE to 0 x 01000000 to 0 x 00000000, change is possible. Well, when I did it in regedit, nothing has changed in the security log properties, the default setting of 'remove older items after 7 days' remained the same.

    Can someone tell me what registry key, I need to change in order to make this change? Keep in mind im trying to include this in a script.
