I would like to disable the default behavior of Firefox which causes links to be drag&drop elements because it prevents selecting part of the text with the mouse in order to copy it. I never drag&dropped a link on purpose, the feature just causes plain frustration for me. There doesn't seem to be a setting for this in about:preferences.
And I also already looked into about:config, but I was not able to find what I was looking for.

So is there a way to change the default behavior without browser extensions?

If you are trying to select text from within a hyperlink on a page and Firefox is trying to drag the link instead, you can override this by holding down the Alt key before beginning your selection.

Unfortunately I don't think there is a way to permanently prevent it from dragging the links (the Alt key temporarily disables clicking links, which you obviously wouldn't want to be permanent).

Note: This is for the Windows version of Firefox. For Linux, you have to hold Alt + Win before selecting. I'm not sure what you would do for Mac.


To prevent that a click into the address bar select the whole string automatically, enter about:config into the firefox location bar and search for the preference named browser.urlbar.clickSelectsAll. Double-click and change that entry to false.
