Status: RESOLVED DUPLICATE of bug 541182

(Core :: DOM: CSS Object Model, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.2) Gecko/20100115 Firefox/3.6

<span style="cursor: url(http://www.SOMEWHERE.org/Figure.gif), help;">42</span>
loads Figure.gif (as seen from the log file from the server), but does not *change* the mouse cursor when it is over the "42". In Firefox version 3.5.7 this still worked.

Reproducible: Always

Steps to Reproduce:
1. Have a website where a custom cursor is defined (e.g. <span style="cursor: url(http://www.SOMEWHERE.org/Figure.gif), help;">42</span> )
2. Point your mouse cursor over the appropriate area.

Actual Results:  
Nothing happens.

Expected Results:  
The cursur should change to Figure.gif (or whatever is given on that page).

Downloaded and installed Firefox "clean", so this should not be a problem of some extension/plug-in/preference etc. (if the system does not force some of those).

Ah, somewhere.org was just an example, did not chekc whether the site existed before posting the bug. Me bad, sorry!

http://kizzume.com is another good example of this--the custom cursor shows fine on 3.5 and earlier, as well as IE and Safari, but not on Firefox 3.6 for Windows.

I had a discussion about it in the Mozilla support forum:

https://support.mozilla.com/en-US/forum/1/583199

It appears to be limited to the Windows build of it.

Um.... how long does it take to confirm something like this?  This was reported at the beginning of the month, it's almost the 16th now.

Attachment: Testcase

Confirming the testcase fails to display the custom cursors on Windows XP with Gecko/20100115 Firefox/3.6 and Windows 7 with Gecko/20100217 Minefield/3.7a2pre

I have to ask... did anyone actually do a search for dups before sending to NEW status here?  ;)

Comment 7

I guess it's a good thing this was duped as I managed to stuff up the custom cursor on link hover in the testcase :)

Yes, I did, but obviously I did not use the right search terms to find bug 541182.

i'm not sure if this is your problem, too, but in my case at least the same kind of thing happened: the same nice cursor working perfectly with firefox 3.5 suddenly didn't appear in 3.6 on windows
the solution: it turned out that 3.6 simply doesn't except cursors greater than 32x32 px...on the mozilla pages (https://developer.mozilla.org/en/Using_URL_values_for_the_cursor_property) it says you shouldn't use cursors greater than this because it's the maximum size of the systems pointersystem in windows...for me skaling down the 45x45 image to 32x32 did the trick

anyway i've got no idea why this had to be, considering that the mozilla-guy seemed to get it working on older versions anyway...and i have to say that even the microsoft-guys did it smarter by skaling down greater icons to 32x32 automaticly instead of letting the users and webdevelopers suddenly stand in the rain..

hope that helps ;)
