Status: UNCONFIRMED

(SeaMonkey :: Web Compatibility, defect)

Description

[alexa]

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0 SeaMonkey/2.49.1
Build ID: 20171016030418

Steps to reproduce:

1. Open a video from https://www.the-voice-of-germany.ch/video
2. Try to seek (by mouse click somewhere in the progress bar)




Actual results:

Video position doesn't change. Seems that the mouse click is ignored.


Expected results:

Position in video and progress bar should change to where the mouse click was.

Sometimes there is an advertisement trailer first where you never can seek, but afterwards you should be able to seek in the normal video.

Safe mode, new profile, complete reinstall of SeaMonkey didn't change anything.

After going back to Seamonkey 2.48 (by installing it over 2.49.1) it works. 
Then after installing 2.49.1 it doesn't work again.

It works on another Notebook with Windows 7 64bit.

Same problem with SoundCloud player widget. The position cannot be set and the mouseover bar is not shown.

Personally this looks like a piece of ... website. More trackers and bogus stuff than you have fingers. It works for me in 2.53 only enabling some of the js sites with NoScript. ABP active with defaults.

Works fine here too. 2.49.2 local Windows x64 build. There are no changes compared to 2.49.1 in the build which should cause problems. In only enabled soundcloud and the soundclound cdn js with NoScript 5.0.10. Maybe Mozilla changed something in Gecko but I can't find an obvious changes in the source either.

@frg: 
Have you tested in Windows 10? Because Windows 7 is not affected. 
Where can I get 2.49.2 (installer)?

I did some tests with nightlies (win32).
Doesn't work in 2.51a1 07-Mar-2017
Works in 2.52a1 12-Jun-2017 and younger incl. latest nightly 2.56a1

In FireFox it doesn't work since 52 incl. latest nightly.

I only tried 2.53 in Windows 10 Fail Creators Update in a vm just now and soundcloud works for me. The junksite too up to the point where video stopped and told me to disable my adblocker. Fat chance I will do this...

2.49.2 is currently in the planning stages. I need to look if we need other bug fixes first before we start building. You can try Bills x64 build from https://www.wg9s.com/comm-esr/ or shoot me an email. I also have a de version available.

I've tried 2.49.2 (thanks for the link), but it still doesn't work.

Is it possible to find relevant changes between 2.51a1 and 2.52a1?

It works in a Win 10 VM on the same PC (same Windows version and build). And it works in Windows Safe Mode. 
Any ideas?

Comment 10

[alexa]

I can reproduce it on the Win 10 VM! 

Simply by enabling multi-touch in Oracle VM VirtualBox:
VM Settings, System, Motherboard, Pointing Device, select "USB Multi-Touch Tablet".

On my PC it works after I updated the touch pad mouse driver to the latest generic version (19.0.19.1, 08-03-2015), directly from Synaptics (instead of Microsoft/Lenovo).

Still on the VM it doesn't work with "USB Multi-Touch Tablet". 
@FRG: can you test this?

Comment 12

[Frank-Rainer Grahl (:frg)]

I have USB completely disabled in the VMs so can't tets it easily. Also only a normal USB mouse connected. Might be some problem with multitouch support in either Gecko or SeaMonkey but there were / are also problems with it in Virtulbox. If you use this one try the latest 5.2.2 first. It has some fixes for touch support. Might be worth a try if upgrading the hardware drivers worked for the real PC.

Tried VM 5.2.2, still doesn't work with multi-touch.
