This is also the case for me, and may be a result of the new Total Cookie Protection. I'm not sure.

This is what I've been getting for the past ~3 weeks. Not sure if it's the same case. I am on Waterfox(up-to-date).

Why are you effectively banning Firefox users from websites? Where is net neutrality?

[Dave247]

I've completely forgot I had this installed, and only took notice of how whenever I would get checks, it would always say DEMO in the top right. So I'm not even sure that when it is "working", that it even does anything at all any more?

Same issue here on Firefox 128.11.0esr.

Same issue nearly a year later in 2025 on version 141.0.3.

There's been no update to the extensions for either browser for 1 year and 5 months.

I may have spoke a bit too soon but I do have this somewhat functional via installing an extension from locally built, unsigned file, which is restricted to the likes of Firefox developer edition

For transparency, I'm using the following versions:

• OS: Linux (6.15.8)

• Attesters configuration from extension options: refer to attached screenshot

• Browser: Firefox developer edition 143.0b7

• Silk version: 4.0.2 built from git hash 6e643c5, refer to attached screenshot

Attached below is the built ZIP using pnpm,
firefox.zip

I do want to emphasise here that you cannot use this on regular Firefox, as Mozilla did mandate signed add-ons and files with xpi file extension.

How I went about compiling this:

• pnpm version: 10.4.0
• pnpm install --no-frozen-lockfile
• pnpm approve-builds (and chose the first option; "esbuild")
• pnpm build:firefox
• pnpm run bundle:firefox

I also got some ideas after reading the package.json, notably the lines that contains the word firefox when it comes to building.

For those who chooses to run this unofficial build, and still face issues, try running it with fewer or without any Firefox add-ons installed. I experimented this with running it inside a new private window, after already granting this add-on the ability to run inside private window, visited a site that I know will prompt me to prove that I am human, and it was successful.
