Cloudflare

[Waltraute]

Waterfox Classic cannot display the many sites that favour 'proving you are human' with Cloudflare. It can't seem to load the silly little tickbox and gets stuck.

To Reproduce

1. Go to '...' Any site that protects itself from visitors with Cloudflare
2. Wait

Expected behavior
To enter and browse the site

Desktop (please complete the following information):

• OS: [e.g. Windows]
  Lubuntu
• Version [e.g. 22]
  24.04.4. LTS

Additional context
Like all other users I hope that someone will be able to take on updating Waterfox Classic. I increasingly have to transfer tabs to Chromium but I still value those XUL add-ons and it remains my default browser. Fixing the Cloudflare incompatibility would make more difference than anything.

No way to even debug this properly and Cloudflare requires too many new API to pass a browser "check". I doubt anyone would fix this. If you absolutely need to access Cloudflare protected page on a legacy browser you can pass verification on your Chromium and then copy cookies and clone useragent string. That would give you a few days of peace.

It seems to be primarily a JavaScript issue, since that's the kind of errors coming up in the browser console. For example, if I try to access a fanfiction on fanfiction.net:

Unable to check <input pattern='.*.(?i)(png|jpe?g|gif|bmp).{0,10}'> because the pattern is not a valid regexp: invalid regexp group  30

I sometimes get other JavaScript errors, but I'm not exactly sure how they're triggered.

Edit: Just managed to fix it with the Polly+ add-on recommended for fixing Github here. Just needs dom.webcomponents.enabled;true selected.
