Page gets stuck on "Proceeding..."

[Car0lina5]

When the extension is active I can't get past any Cloudfare captcha, not even the website "https://captcha.website/". If I disable the extension, the captcha works normally.

1. Using the Floorp browser, click on the extension
2. Click on get more passes
3. Try to complete the captcha

Expected behavior
The page will get stuck on "Proceeding..."

System (please complete the following information):

• OS: Windows 11
• Cloudflare tokens or hCaptcha tokens? Cloudfare
• Browser: Floorp Browser
• Browser Version: v10.13.0
• Privacy Pass Version: 3.0.5

Additional context
In other forks of Firefox the extension works normally, but for some reason in Floorp it doesn't work. This browser is getting a little popular and I would like to start using it. I don't know if anyone will be able to help me, but it doesn't hurt to try. Thanks anyway.

Hi @Car0lina5,

Thanks for openning an issue.

We would need more details to better investigate.
Could you provide an HAR file, recording your session when accessing captcha.website, and attempting to complete it?

To do so:

1. Open the developer console. see
2. Click on the Network tab
3. Now, go to https://captcha.website
4. Once you reach the state you mention in your first ticket, being stuck at "Proceeding", export the HAR by clicking on the cog icon of the network tab.

Hello, I don't understand much about this but I hope I collected it correctly.

Having the same problem, the POST request gets blocked by the firefox extension.

I am also reproducing the POST request being blocked by the Privacy Pass extension (version: 3.0.5; installed from AMO; ID: {48748554-4c01-49e8-94af-79662bf34d50}) in Firefox (version: 118.0a1 (2023-08-07); update channel: nightly; build ID: 20230807215239; OS: Windows_NT 10.0 22621).

cURL syntax of the blocked POST request

curl 'https://captcha.website/' -X POST \

Also replicating this behavior in Firefox Developer Edition.

OS: MacOS 13.5
Browser: Firefox Developer Edition 117.0b5 (64-bit)
Extension Version: 3.0.5 (Installed from Firefox Addons Store

I went ahead and pulled up the extension debugger and it appears the root cause is the request being made by the extension is getting a 403 in response from Cloudflare. I've attached the HAR for the request made by the extension.

pp_request.har.txt

Not sure if someone just changed something on the back end right before I submitted this (I was typing this response so no changes were made on the browser when it happend) but I was somehow issued 60 tokens while not even looking at the "Just a moment" tab.

Will definitely be keeping an eye on it to see if it is actually working.

This bug with the page being stuck in "Proceeding" does not seem to happen with Firefox 119.0.1.
Major fix to the extension is being tracked in #400.
