User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:51.0) Gecko/20100101 Firefox/51.0 Build ID: 20161114004005 Steps to reproduce: Reproducible in FF 51 through 53. 1) Open any image / video. Sample image: http://i.imgur.com/Z0LU4lT.png. 2) Zoom in or out on the image so as to be at a zoom =/= 100%. 3) Now click on the image. Actual results: A) With the zoom percentage / + / - combo button (the one that looks like this - http://i.imgur.com/836AAdo.png) placed in the hamburger menu: the actual zoom of the image is reset but the indicator in the awesomebar isn't. However, the indicator in the hamburger menu has been correctly reset. Gif showing the bug: http://i.imgur.com/26wmoHd.gif (click marks the point at which the zoom is abruptly reset, STR 3). B) With the zoom percentage / + / - combo button placed in the nav-bar: the actual zoom of the image is reset but now even this combo button display an incorrect zoom level. Gif showing the bug: http://i.imgur.com/JEX4Oj5.gif (again, click marks the point at which the zoom is abruptly reset, STR 3). Expected results: Either the zoom level of the images / videos shouldn't be reset upon clicking, or the zoom indicators, whether the one in the awesomebar or the combo one, should show 100% zoom even upon clicking on the image / video.

I expect this is a frontend bug, made more noticeable because of the URL bar zoom indicator.
Component: Layout: View Rendering → General
Product: Core → Firefox
The basic problem here is that the code added in bug 565718, i.e., https://hg.mozilla.org/mozilla-central/rev/ef0801fdc7ab , doesn't interact with the image document code in https://searchfox.org/mozilla-central/source/dom/html/ImageDocument.cpp . I guess it seems a little bit odd to me that the notifications that it's hooked up to are global notifications for certain browser-triggered actions (which will update the zoom in every tab at once!) rather than notifications for changes to the relevant tab, from the code that controls the zoom for that tab. I think it would be preferable to observe the zoom more directly (and less globally), so moving this to the Firefox component rather than the image document component (neither of which is Layout: View Rendering).

The indicator also needs updating for tab switches, or when new pages load in the same tab that then are subject to a different zoom level because of site-specific zoom.

tracking 53+ for this bug since we should show the zoom level correctly.
Track 51+ as the zoom level is not shown correctly.
jaws, can you suggest someone who might work on this? Asking since you were the reviewer for the patch from bug 56718. Thanks.
Too late for 51, marking this fix-optional for 52/53 since we haven't yet found someone to work on this regression.

I tried that but it's not getting hit in the debugger. The event will be in the content process, presumably? So the listener would need to be, too.

So, this patch *should* work, but win.ZoomManager.zoom doesn't always return the expected value. In fact, with this patch it never returns 100 unless I step the debugger through here, allowing enough time for the viewZoomOverlay.js's getZoomForBrowser -> remote-browser.xml's fullZoom to update. This seems very similar to bug 1310758. Gijs, do you have any ideas of what we can do to work around this? Preferably something quick-and-dirty because I don't have the time to spend working on a rewrite ;)

AIUI you should be able to pass it up from there and remove the synthetic document guard and use only that notification to update the zoom indicators for loads (as long as you cache per tab and update after tab switches). Of course, I could be wrong. :-)

Of > course, I could be wrong. :-) Yeah, I agree that this is the better route to go for updating zoom values, but I don't have the time right now to rewrite our code and deal with potential regressions. The patch I'm attaching uses your feedback but only fixes this specific bug.
Comment on attachment 8838195 [details] Bug 1318830 - Listen for the FullZoomChange event on synthetic documents to trigger updating the zoom-control in the location bar. https://reviewboard.mozilla.org/r/113160/#review114666 ::: browser/modules/URLBarZoom.jsm:45 (Diff revision 2) > if (zoomFactor != 100) { > // Check if zoom button is visible and update label if it is > if (zoomResetButton.hidden) { > zoomResetButton.hidden = false; > } > // Only allow pulse animation for zoom changes, not tab switching Seems this comment should move to inside the observe function. Also, can we ensure somehow that the value is actually changing here? If it doesn't, and we get called, we should ideally not update. That's a bug that looks like it existed before, though (e.g. if you navigate from a page with 120% zoom to another page with 120% zoom) so no big deal if that's hard to do (followup for that and the other stuff we discussed, though).

I couldn't find a way to get this to occur so I didn't add code for it. I tried having two websites open both zoomed to 120% and then using the same tab to navigate from one to the other. There wasn't any animation. I did the same test with image documents.

Jared, this doesn't look to have helped on Nightly. Or maybe it was broken by other changes in this area? On Nightly, I don't see any URL bar zoom indicator anymore when changing the zoom level using accel-mousewheel or the keyboard shortcuts.

This is working for me on Nightly 55.0a1 (2017-03-08) (64-bit) on Windows 10. I just confirmed by testing with https://msujaws.files.wordpress.com/2014/05/floating-head.png?w=75. accel-mousewheel and keyboard shortcuts get the zoom indicator to appear, and clicking on the image resets the zoom level to 100%. It sounds like RyanVM figured out why you weren't seeing it.

Oh, yeah, so the additional confusing thing was that we don't show the in-URL-bar thing if you customize the control to the toolbar, and I'd forgotten that subtlety... Sorry for the confusion!

Okay, I can add a note to bug 1345375 about this not working if the zoom controls have been moved to the location bar. We need to update CustomizableWidgets.jsm too to listen for this.

We should wait for bug 1345375 but it just landed on autoland a couple hours ago. If we can wait another day or two then it will have gotten to Nightly and we can verify that bug through manual QA. At which point we can begin the uplift process.

[Tracking Requested - why for this release]: Moving from + to ?, I would prefer that we *not* uplift this to 53beta since we're only two weeks away from merge date and the issue is not so severe (only the UI doesn't update but the image zoom does change).
Is this worth taking on ESR52 or should we let it ride the 54 train?
