Firefox: Drag and drop access revoked if open the same applet in new tab

I have an uploader application that allows for drag and dropping of files from the desktop, works great. In Firefox 3, if you go to the uploader and drag files onto it it works, if you then open a new tab in the same window and navigate to the URL that contains the application you can drag and drop files into that new application window, if you go back to the previous tab however you can't drag and drop files on to that instance of the app anymore. Is this a known issue?
Thanks,
Sam

This is an applet?

Why does rightclick+t on a link open the link in a new tab, yet rightclick+t on a bookmark on the toolbar grays it out?

This happens to be more of an issue using a trackpad. Then you rightclick on a link and then hit "t" it opens the link in a new tab. when you do the same command on on a bookmark on your bookmark toolbar, it grays the bookmark out. none of the settings have been changed on it. the way to fix it, i discovered is to right click on the bookmark and hit "p" no idea why, but this solved it. I can't find any of these command online, partly i don't know how to correctly search the rightclick command, but partly, it would only probably list the commands that actually show up as stuff to click with your mouse.
I would also like to know why for two different locations that both open a link in a new tab, why the mapped shortcuts are different. for a link, it is rightclick+t, for a bookmark it is rightclick+w. I mean, make it the same commands, it makes much more sense that way.

Because the "T" in "Open Link in New Tab" is underscored in the link context menu (right-click menu)
You are on Windows 7 and by default Microsoft hid that useful information by default in all of their menus.

Toggle keys appears both under mouse and under keyboard in Ease of use / Accessibility options.
 Though I would like to activate the last option, preventing windows from being automatically arranged
would also deactivate my favorite Windows 7 added WinKey+<arrowkey> keyboard shortcuts to resize window to left/normal/right side, or to maximize/norm/minimize window.  On a dual/extended monitors this would be left/norm/right on each monitor so left/right arrow actually have six positions passing between monitors.
 Please mark "Solved" one answer that will best help others with a similar problem -- hope this was it.

When moving a file using drag and drop, as I hover over the destination folder it no longer opens, so I can't drop the file into the folder. Why?

When moving a file using drag and drop, as I hover over the destination folder it no longer opens, so I can't drop the file into the folder. Why? I have a heirarchical embedded folder structure under \Documents. Usually, as I drag the file to be moved over the various folders, they will blink twice, then expand/open to reveal contents (in Finder). Now, when the file to be moved is held (hovering) over the destination folder, it will not blink or expand, so there's no place to drop the file. If I release the mouse button, the file image disappears, showing that it is "going back to the place it came from", a.k.a. was not moved. This just started happening. I noticed it after upgrading to Mavericks. Is this a bug or could anything else be causing this?

As of today, Apple Support discovered during a remote support session with me that the same thing happens on their own system. It is isolated to "Column View"; the Icon and List views in Finder behave correctly. Issue is being escalated to engineering, and Apple will call to report status in a couple days. In all likelihood, this is a bug that will need to be addressed in a future update.

Pls Help! Drag and Drop problem, identical symbols acting differently - same code! WHY?

In the attached file, I have a series of symbols that have a drag and drop command to change colour at different sections of a bullseye, and that are also text editable (html).
However, some of the symbols get stuck and will not be moved after moving once or at all, and some get stuck once their text has been edited.
I have poured over the code and it appears to be the same for each symbol - can anyone explain as to why this is happening?
I also cannot now edit the text properly on the ipad (it is really fiddly to change between different symbols to edit their text -- is there maybe a better way to do this? A button to change between symbols to then edit their text, can you help with this too?)
THANK YOU SO MUCH!!!

ADF EBS Integration - How to open the ADF page in new tab or window

Hi,
We are building ADF custom applications and want to integrate them with EBS R12 (12.1.3) through Responsibilities and Menus.
We have achieved session sharing and launching the Custom ADF app from EBS menu. The problem is, the Custom ADF page opens in the same page.
Is there anyway to open the ADF application in new tab or window while launching from EBS Menu ?
Highly appreciate your help on this.
Thanks,

Firefox Drag and Drop Image to AI CS6 - displaces art on art board...

When dragging and dropping an image from FF 20/21 into AI CS6, it forces elements on the art board to be displaced.
The image dragged into the app will plop into the middle of the art board, and anything in the file just gets moved.
Where it gets moved to is inconsistent- but it appears to always move on a diagonal.
Probably one of the weirdest things I've ever seen AI do, in 10+ years...

It turns out that this doesn't only happen in Firefox, but the results appear (at this point) to be completely random.
It happens in some instances in Chrome, but less frequently.
Also, I have some examples where it is not happening at all in Firefox.
Can't find a common thread for the problem- it's not a browser version or AI version thing, it's not a file version thing, it's not even, seemingly, the results of the objects being dragged out of the browser.

I have 2 auxillary disk drives for my MacBokk Pro. Time Machine uses one for backup and I use the other for storage, but I am unable to create a new folder or drag and drop files or folders to the aux drive.

I am unable to create a new folder on either of my auxillary disk drives. I can access the files and folders that were there when I transferred one of the drives from a PC. Time machine uses one for backup and I want to use the other to store photos which are large files. An help would be appreciated.

Thanks for the reply. If I reformat the drive will I be able to access the files on it from the MAC. I do not share the drive with a PC. The files were originally created on a PC which I no longer use. I do want to continue to access the files put there by the PC. I would like to not have to copy them over to the MAC hard drive just to use them. The second aux drive is new and works fine because it was formatted by the MAC. I can drag and drop files there and work with just as if they were on the internal drive.

I have a 5th gen iPod Touch. I have made playlists in iTunes. I need to get them to the iPod. When I had a Classic, it was automatic. You could drag and drop using iTunes music to the playlist in iTunes and it would automatically sync to the Classic.

I have a 5th gen iPoc Touch. In the past, with the Classic, I could drag and drop from my iTunes music to a Classic playlist through iTunes. Now, the playlist I create in iTunes doesn't show on the Touch. I have maybe 29 GB of music on my Touch. I have already created playlists in iTunes that have substantial amounts of songs in each. How can I get those playlists on the Touch without doing a total sync that wipes the iPod? Is there a way to do it?
As well, I am noticing here that my 5th gen iPod doesn't show as a registered device. How do I register it?

For how to sync see:

I no longer have iTunes library.xml on my PC but I have all of my songs. How do I download them to my iPhone - it won't allow me to drag and drop though my PC recognizes the device.

My PC has all of my iTunes and it recognizes my iPhone 4 device but I cannot drag and drop the songs. How do I copy the songs to my new iPhone without having to re-purchase everything? Unfortunately, It appears I no longer have iTunes Music Library.xml on my PC.

My husband and I are using the same iTunes account on all mac & pc computers, but the libraries are different on each machine. We always manually manage our music (no auto sync). iTunes is up to date on the PCs. My husband uses our joint iTunes account on his pc, but once again, has a different collection in his library from those on the other machines. He can't load any music from his PC to his iphone 4. I can load music from my mac library to my iphone 4s, but cannot load from my pc library to my iphone 4s. How can I switch my main library that it syncs with from the mac to the pc?
Thanks

There is absolutely NO way to drag and drop newly purchased music from the Purchased list on the phone into my iTunes library? I'm finding it hard to believe that something so simple cannot be done!

I like to make MP3 CD's when I have people over, or when my friends have people over so I can just pop them into the CD player and let them play all night without having to worry about changing the CD or anything. Well, Apple's music is in AAC format, so I have to convert the songs to MP3 files using the converter in iTunes. So I'll convert them to MP3's and just delete the AAC file so I don't have doubles. The problem is, the next time I plug the phone into my laptop to transfer new purchases, iTunes thinks that the songs I converted aren't there anymore because the phone has them as AAC files, and iTunes has them as MP3 files, so it doubles the music again...EVERY time!! It's very frustrating! So this is why instead of clicking Transfer Purchases, I would like to be able to just drag and drop the songs I want from the Purchased list on the phone into my iTunes library. I hope I explained this right...lol. Unfortunately, it doesn't seem like I'm able to do that. I'm hoping maybe somebody here can help me out and give me some pointers on what to do about this. Thanks!!

That stinks! I can actually do that at my house...I just plug my iPhone right into the wire that's plugged into my receiver in my living room...but some of my friends aren't "technology savvy"...lol...so they just have DVD players and I'll put the CD in there because it will read an MP3 disc. What's funny, is I have the phone set to "Manually Manage Music", and when I plugged it into the laptop just now, the one song I downloaded last night on the phone, transferred over to the iTunesl library. That NEVER happens. And it only transferred the one song...it didn't double the other songs like it ususally does. I swear, iTunes does what it wants, when it wants sometimes...lol. Thank you for your quick response.

How do you drag and drop/move multiple emails from the inbox or mail archive folder to a file folder in your finder?

I would like to archive hundreds of my emails that currently exist in my apple mail email filing system by moving them into file folders in the finder. I can do this easily with a single email but it wont let me do it with multiple emails or a complete folder. Is there any way of do this easily?

Thanks very much for this. However, I understand how dragging and dropping files normally works. It just seems the it wont work when you do it with emails when you are transfering them into a normal finder system folder. If you highlight one file and drag it to a finder folder it works, but when you drag multiple, it just wont let you do it.
Is there any work around for this? Thank you once again for your time.

The other option besides the drag_n_drop support

Drag and drop, it won't release the file.

Upon booting up my 15"MBP with osx Lion, when I drag and drop a file, it won't release the file. This happens across files, other programs, etc. The only fix is to put the computer to "sleep", then when it turns back on drag and drop works fine.
Is there a fix for this issue? It happens on every boot up.

To clarify, it's not just Air DIsplay but any third-party video driver. When any of these is installed (not even necessarily active) on a MBP5,1, MBP5,2, or MBP5,3, you'll have this issue. The workaround is detailed here: Air Display on Lion with NVIDIA 9400/9600

This might sound like a strange question but in the past I was able to select a group of files in a window and drag that group to the desktop where they would stack upon one another creating a neat stack of all the files in one place. Now when I do this they drag onto the desktop and remain spread out all over the place. It's not terribly difficult to deal with except if I'm dragging say, 30 photos onto the deskop. Before they appeared stacked upon one another and I could simply drag one off the stack one by one. I am however experincing harsh symptoms of OCD because I can't figure out why. My co-worker's Mac is the same as mine (both running 10.8.2) and his files stack just fine.
I've done a fresh install after having no luck and it's till doing it.
This is really bumming me out. Any suggestions are very welcome. I've even booted into safe mode and it still won't stack drag and dropped files onto the desktop.
Thanks for any advice,
-Jason

Relaunch Finder and restart Mac OS X. See if this helps.

Firefox: Drag and drop access revoked if open the same applet in new tab
