[Affected versions]: - Latest Nightly 59 - beta 58.0b14 - Firefox 57.0.4 [Affected platforms]: - Ubuntu 16.04 x64 [Steps to reproduce]: 1. Launch Firefox and open an image (ex. http://www.catster.com/wp-content/uploads/2017/08/A-fluffy-cat-looking-funny-surprised-or-concerned.jpg) 2. Use Ctrl+scroll to zoom in until the image is bigger than the browser window 3. Observe the cursor's behaviour. [Expected result]: - The cursor changes into a magnifying-glass that shows the actions you can do (zoom in or zoom out) [Actual result]: - The cursor remains the same. [Regression range]: - Last good revision: 19289cc8bf6ffce3b2067fbe91aebea5a356d00815:16.87 - First bad revision: 7ac30073bcac75a1f0217a342300233a4a2d939e15:16.87 - Pushlog:https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=19289cc8bf6ffce3b2067fbe91aebea5a356d008&tochange=7ac30073bcac75a1f0217a342300233a4a2d939e I assume that the bug 1328724 is the cause of this issue.
I can't reproduce, on Ubuntu 17.10. I tested Firefox Nightly 59.0a1 (2018-01-08) and the ubuntu package of Firefox Release 57.0.4 (64-bit) -- and in both, I get Expected Results. (I do see a magnifying glass when performing the STR.) Maybe there's something Ubuntu-version-specific (note that my Ubuntu is newer than Oana's). It does sound like some others are able to reproduce, per bug 1328724 comment 7 and bug 1328724 comment 8 -- just not me.
Priority: -- → P3
Based on a user's comment on bug 1328724, it sounds like the issue here is theme-specific -- according to this user, you get expected behavior if you've got the "Adwaita" cursor theme, but broken behavior from other themes like DMZ-White (and the theme has to be chosen before you start Firefox). Incidentally, Adwaita is the theme that I am using (and indeed, I'm getting correct/expected behavior). Here's the full text of that user's analysis from bug 1328724 comment 8: > zoom-in/zoom-out cursors are no longer displayed with Linux Mint > 18.1 Cinnamon 64-bit. > > I did not change the theme after installing Linux Mint, and Themes settings > currently says that "DMZ-White" is in use in "Mouse Pointer" category. > > Observations: > > - Switch to "Adwaita" as "Mouse Pointer" theme, the zoom-in/zoom-out cursors > are then properly display on the doc/demo MDN page > - Switch back to "DMZ-White", the zoom-in/zoom-out cursors are *still* > properly displayed. > - Quit then launch Nightly, the zoom-in/zoom-out cursors are no longer > properly displayed. > - Switch to "Adwaita" as "Mouse Pointer" theme and quit then launch Nightly, > zoom-in/zoom-out are properly displayed. > > So it appears if "Adwaita" was enabled at any time at least once while > Nightly is running will fix the zoom-in/zoom-out cursor issue even if going > back to non-"Adwaita". Re-booting Nightly without "Adwaita" however and the > issue is back. > >  https://developer.mozilla.org/en-US/docs/Web/CSS/cursor?v=example
