Qwen does not load if DDG Privacy Essentials extension is turned on in Firefox

[lucasalbuquerque57]

Description

In Firefox, when you load up the main page of the Qwen (LLM), https://chat.qwenlm.ai/ while DDG Privacy Essentials is On, it loads infinitely, and can only be fixed after turning it off

Steps to Reproduce

1. Use Firefox 134.0.2 (64-bit) on Windows 11 24H2
2. Check if DDG Privacy Essentials extension is On (version 2025.1.15)
3. Load the https://chat.qwenlm.ai/ page, it will load forever

Expected behavior:
Qwen page should load

Actual behavior:
Qwen page loads infinetely

Versions

• Extension: 2025.1.15
• Browser: 134.0.2 (64-bit)
• OS: Windows 11 24H2

Additional Information

This issue did not change after clearing cache, reloading the page, using containers, or disabling other extensions. I disabled every single one, and the Qwen page worked perfectly, but then after suspecting of the DDG extension, I turned it on, while having all others off, and the Qwen page stopped loading.

Experiencing the same now.
Qwen moved to new domain: https://chat.qwen.ai/

@lucasalbuquerque57 Any solution or workarounds?

@yashasnadigsyn not yet, I'm just letting the extension disabled. If this was an intended thing by the Qwen team, it would also happen with addyio and simplelogin, but it doesn't. I'm completely in the dark
