1380239 - Ctrl+mousewheel frequently stops working

Status: RESOLVED WORKSFORME

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Katelyn Gadd (:kael)]

Periodically, ctrl+mousewheel to zoom stops working in Firefox. I see it multiple times a day, and when it happens it is typically limited to only some pages - if I switch tabs zooming there sometimes works. It may be a per-content-process thing? I've only been seeing it for a couple weeks, I think.

For example if I visit http://images.anandtech.com/doci/11544/intelomnipathxeonv5_678x452.png directly (like by clicking a hyperlink on twitter), so far every time I've tried that, ctrl+mousewheel does nothing. If I switch back to my Twitter tab I can zoom there. If I leave the image tab active and switch to another native app (LINE for example) and then come back to the tab, ctrl+mousewheel works again. Once I've "fixed" it that seems to stick for a while but then it breaks again.

Not sure how to reliably reproduce this other than that I'm seeing it a lot and it drives me crazy :)

Just to be clear, this is a mouse wheel and not a trackpad, right?

Stone, do you have any ideas here?

Mousewheel, yeah. Bluetooth mouse (not that I think it should matter, it's still a regular pointer-and-wheel mouse)

Hi Kael,

Sorry for the late reply. Is this problem still reproducible recently? I used the nightly build (2017-08-27) on Windows10 but can't reproduce it.

I have not seen this recently. I will update the bug if I see it again.
