There is a privacy setting in firefox that causes this for me on most websites that require photo upload, not all sites, but consistently the same sites.
Ebay for instance, most reverse image searches etc.
in about:config - > privacy.resistFingerprinting
It might not be that setting specifically, but turning that setting to “false” does fix this for me.
There might be a more granular setting that does the same job but i don’t know of it.
Not that i’m recommending turning that off, that’s your call.
There are eleven settings that start with “privacy.resistFingerprinting”. The first one, which only says “privacy.resistFingerprinting” is set to False by default and I still get the colored vertical lines.

I’ve also not tried it on this site specifically.

In my setup only three of them are altered from the default values.
“privacy.resistFingerprinting” is the one i was talking about specifically, which works for me in the scenarios detailed in my response.
It’s been a while since i setup this install but i know i used the arkenfox scripts as a baseline.
I have no idea how much deviation i have for the default baseline so YMMV greatly.
I only mentioned that setting because it’s one i use to fix my specific problems and it might help as a starting point.
