HI, have you checked the Scarlett 2i4 Support out to see what they have ? https://support.focusrite.com/hc/en-gb

Running a Alpha maybe the cause of this and it will be a new version before find a fix for it. Also : If you have a bug, file a bug report. https://bugzilla.mozilla.org/ Bug Writing Guidelines : https://developer.mozilla.org/en-US/docs/Mozilla/QA/Bug_writing_guidelines

So see if something works out of these .

Hi, I already tried installing the latest drivers from Focusrite, althout I highly doubt it had something to do with them, as the problem didn't happen with any other application.

For some reason the problem is now fixed, I didn't update a thing since my original post, yet it magically disappeared. It was quite severe before, but now it's completely gone.

I guess writing here solved my problem in some way! Maybe win10 updated something during standby without me noticing...

Great. Glad fixed itself. Let us know if you need help.

Unfortunately it just came back, and then it kind of went away after just playing a video on another app... It still happens, but far less frequently, like 1 or 2 frame skips every minute. I don't know what to think... It still only happens on firefox.

Hello,

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

You will need to restart Firefox for this to take effect so save all work first (e.g., mail you are composing, online documents you're editing, etc.,) and then perform these steps:

In Firefox 54 and below:

1. Click the menu button and select Options (Windows) or Preferences (Mac, Linux).
2. Select the Advanced panel and the General tab.
3. Uncheck Use hardware acceleration when available.
4. Close Firefox completely and then restart Firefox to see if the problem persists.

In Firefox 55 and above:

1. Click the menu button and select Options (Windows) or Preferences (Mac, Linux).
2. Select the General panel.
3. Under Performance, uncheck Use recommended performance settings. Additional settings will be displayed.

   

4. Uncheck Use hardware acceleration when available.
5. Close Firefox completely and then restart Firefox to see if the problem persists.

Did this fix your problems? Please report back to us!

If the problem is resolved, you should check for updates for your graphics driver by following the steps mentioned in these Knowledge base articles:

• Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

• Upgrade your graphics drivers to use hardware acceleration and WebGL

Thank you.

Hi, I had already tried this and other solutions. I'll try it again later today, thanks.

Unfortunately disabling hardware acceletarion didn't fix the problem.

I have noticed that the frame skips are more heavy on long videos.

What is your ISP speeds and link to the video that is doing the problem.

Every video on any website and quality has this problem. Even audio-only streams have it, like SoundCloud.

It's 30Mbps download speed.

I found the problem.

My webcam was malfunctioning, Windows continuously detected it plugging-in and out. I plugged it out and videos played normally.
