• OK in Waterfox Classic 56.2.14 on Windows 10
• will not play in Waterfox Current 68.0b1 (20190908151900)

We're experiencing a problem playing this video. For assistance, please go to www.amazon.co.uk/videohelp.

Tested:

• the movie at https://www.amazon.co.uk/gp/video/detail/B00X674KKU
• not the trailer; this does not use DRM.

The version of the Widevine CDM is only marginally different (4.10.1440.18 in Current, 4.10.1440.19 in Classic):

I doubt that a UA override will be effective in this case. I tried both of these:

Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0 from Firefox 60.9.0esr (64-bit), which can play the movie

Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:68.0) Gecko/20100101 Firefox/68.0

I am aware, Widevine needs an update.

– although with Waterfox 68.0b1, this may not be the case.

– and confirming what askelam reported in Reddit, inferior 4.10.1440.18 does work as expected on (Manjaro) Linux:

• tested with the example from the opening post, https://www.amazon.co.uk/gp/video/detail/B00X674KKU

Netflix error F7121-1331 on Waterfox Current

https://redd.it/dp5vma for Waterfox _Classic_ 2019.10 observes a workaround that involves trimming the Waterfox-specific tail from the UA string and applying the override to specific sites (not universally).

Waterfox Current 2019.10 for Windows uses no such tail:

Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:68.0) Gecko/20100101 Firefox/68.0

I don't have Netflix, can't test.

Can any user of Netflix on Windows tell whether late October build 20191022131008 of Waterfox Current 2019.10 is free from error F7121-1331?

Thanks
