I notice for GVE and Fenix we use 'about:blank' for the default page, for fennec the default page on app startup is 'about:home'. If after browsertime starts the fennec app, and during the 'post-startup-delay', I manually navigate to 'about:blank' then the orange screen does appear right before navigation to the test page (i.e. www.amazon.com) begins. However even so, after the test finishes there are no videos found in the browsertime results and I see the same error:

DEBUG: [browsertime.video] Using window recording directory: undefined

I check on the device's sdcard and there are no video recordings there (they are expected to be in /sdcard/browsertime-firefox-windowrecording

Hey :barret, is the windowUtils.setCompositionRecording API supported in fennec (more specifically fennec 68.5a1)? Looks like the API is being called via browsertime/webdriver, and I don't see any error messages returned - however no video recordings are created.

[Barret Rennie [:barret] (they/them)]

It should be. I see all the relevant bits except the WebRenderCompositionRecorder on the esr68 branch, but we shouldn't be using WebRender on Fennec.

I'm pretty sure that this error is fixed now. We can reopen it if need be.
