How can I find the which extensions (plugins, not) are currently installed by using JavaScript?

I created a JavaScript module that allows to detect if a Firefox extension is installed in the client browser.

I can check if a Firefox plugin is installed by querying navigator.plugins object, but I can't understand how to extensions.

You can not check for extensions that are installed.

Plugins can be detected through navigator.plugins you posted, but you can not detect the extensions for reasons of confidentiality and security.

It's the past, it was possible to check the images added by an extension, but that access has been blocked.

  • How can I find the images that have a resolution below 1920 * 1200 using search in Windows 8?

    I'm trying to find images in a folder to have a resolution of 1920 * 1080, but can only find how to search specific sizes - what is useful, but not what I need.

    Any help is appreciated.

    No longer think that it is-just try logic.  :-)

    Search for width and height.

    Example - if I had a folder (with subfolders even) I wanted to find all moroccoin who had a lower width to (but not equal to) 1920 (which is what you say, to halfway anyway) then I'm looking for:

    Width:<>

    If I wanted all the images to a width smaller than 1920 and height less than 1080, so I'm looking for:

    Width:<1920><>

    (... which is what said you you wanted.)

    Of course, who does not account turned images where width is now 1080 and the height is now of 1920.  ;-)

    If I wanted that all the images that are less than or equal to a measure...

    Width:<=1920><>

    Etc and so on...

    All of this assumes that images have been properly encoded with metadata, indexed, etc..

    It can also take some time to process...

    Works for Windows XP I think.

    What you might see in a results pane:

    This image is Windows 7, because that is maybe I was sitting in front of in time.  Should be very similar/same to search for files (FILE SEARCH is the key it) in point 8.1 of Windows...

    Note that I added the width and height to the columns for easy sorting - heck, that could solve your problem here.  Go to the root directory (all subdirectories has included in this one you can photos on) and research of *. * and with the width and height columns add, once the search results show all the ions of files files - click one of the column headers to sort (say by width) and you will find a list of images in all of the folders located under him you started with a width of all together, etc.

    But - you seemed to want to put the width & height together, then...

    Dimensions:<>

    However, in my tests, it is less reliable than the width and height - as I am less than or equal to 1920 and height, it was whatever he felt like.

    May arise through this:

    2 type the following in the address bar of the browser. If you use a Linksys router type in "192.168.1.1" and if

    3. If everything is is well past that should open a page which says that Linksys or Belkin.

    always be the factory settings and then enter "admin" for the username and "password" for the password. If you are using a

  • How can I find out which catalog a missing image belongs to?

    How can I find out which catalog a missing image belongs to?

    Beat a dead horse... Whenever I need "missing images", in LR4.2, I can't access it, even if I'm looking to the right of the location that they presntly occupy thye picture was ALREADY in a CATALOG OTHER.

    HOW frustrating it is... going on 8 months now. But I need pictures and I guess I could just go back and 10,000 images that are missing in my collections to reprocess but I tried a lot of solutions offered in the months that are just not practical.

    So now, I want to approach this thing from the other direction...

    If Let's say a single image is already associated with another catalog which houses this collection, (and the collection is important because there changes), I want to go instead of this catalogue.

    How can I do this?

    Any ideas?

    Now, I see the video. AFAICT the message, it's not telling you that the image concerned is also imported into another catalog. You say that you already have an image version different within this current catalog, which already makes reference to the same physical file, you're trying to re - adjust the offline image to.

    This duplicate version is (I'm 90% sure) the result of a re - import at some point after you have transferred the data in the new computer. The proof will be if the two folder/drive locations appear in the records of LR.

    Say there is an [X] image that becomes an orphan, because the location of its source [A] file is no longer available.

    As has been explained, the right solution is to update the location information - it is easier to do in the record IMO, or a whole folder, instead of an image - tree so that the image [X] beyond knows to use the location [B] instead of [A] location. Incidentally, this means [A] record disappears from the list of files to LR and folder [B] appears here.

    However the situation is badly knotted up so instead to the foregoing, the [B] file is imported as fresh images, creating a new and separate image [are] pointing to the same file moved this image [X] used to use in the old location (for example).

    [X] is still in all of your Collections already made and has all its changes etc., but (with no now accessible at A location source file) cannot be used.  [There] was all or part x edits, will not be in one of your Collections, but works otherwise - because she doesn't have a working reference to the image file to location B.

    If you now try to redirect Web image [X] notebook file B, Lightroom rightly complains: ' you already have image [is] referring to this file!

    So if you delete these (I guess, superfluous) additional imports of LR - the backup catalog first and do NOT choose Remove them the disc! -LR will no longer have any reason to block you re - treating your images established and thus put online.

    I wonder if referring to pictures only through Collections (as in the video), one would tend to miss what's going on with these physical folder locations? It may be useful (even if you do not pay much attention to the location of the files, otherwise as LR allows rightly) - to select "Go to folder in the library" against a given image, for repairs in such cases.

    Best regards, PR
