Firefox: Can't drag URLs to Links bar

Try running firefox in safe mode and see if it works then? Just to avoid confusion, I mean the safe mode version of firefox, not running firefox in windows safe mode.

It should be in your Start Menu under Mozilla Firefox.

Then it might be one of your add ons causing a problem. Disable whatever add ons you have one by one and try and find out which one it might be causing the problem.

Change your folder option to view hidden folder and go to your user name and go to AppDatta/Roaming/Mozilla and rename the folder to Mozilla (2) and start up Firefox and see if you can now drag your URL's to the links bar, if that works it must be a setting or addon that has caused your problem and you will need to delete the new Mozilla folsder and rename the old one again and find out what setting it was that stopped you.

The solution for re-enabling drag and drop in Firefox was quite simple: Ensure the "Run this program as an Administrator" check-box is unticked in the windows Firefox shortcut compatibility settings.

If you were like me, you may have previously enabled that compatibility setting to resolve issues with other Firefox addons, unknowingly disabling drag-n-drop from the desktop to firefox. With recent addon updates, I found that running in administrator mode was no longer needed.

Hope this helps a few of you with this frustrating problem.

Unfortunately, as this thread is over 6 years old, many things have changed since then, as far as how Firefox works.
And it's probably unlikely that the OP or others are closely following it by now.

Thanks for your helpful input, though!
