This extension is getting bypassed by some websites

[youngunix]

This extension doesn't seem to be effective against a certain websites such as "open-vsx.org. The only way to get this website to recognize the custom useragent is via the Developer Tools on Chrome. This is definitely not a solution nor a workaround that needs to be adopted since it only works on the tab you set it for (as apposed to all the open tabs) and for that session only.

Hey young man!

How can I see what user-agent https://open-vsx.org/ detects?

Unless I'm misunderstanding - it looks like youngunix is right, using firefox's Network tab and loading the site, there's the odd request header that is showing:
Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:131.0) Gecko/20100101 Firefox/131.0

Whilst my agent is set to, and on the majority of requests states it is:
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/124.0.0.0 Safari/537.36 OPR/110.0.0.0 (Edition Yx 05)

The request which sends the wrong header that i saw (there are more):

GET

I saw a second one:
GET https://openvsxorg.blob.core.windows.net/resources/stateful/runme/darwin-arm64/3.9.0/icon.gif

I came across this issue as my Youtube doesn't work with this enabled - and I could see some requests with my actual user agent being sent.

Blacklist mode: cloudflare.com
Disable spoofing: gitlab.com/users/sign_in

Everything else is as default except I have it set to show debug in console, but it doesn't seem to do that.
I'm not sure if any of that's helpful or if it's expected or what.
