**[Affected versions]:** - Firefox Beta 143.0b5 - Build ID: 20250827090822 - Firefox Nightly 144.0a1 - Build ID: 20250828092344 **[Affected Platforms]:** - Windows 10 x64 **[Prerequisites]:** - Have a Firefox en-US locale installed. - Have a Firefox profile older than 7 days. - Have FxA enabled, but you are not signed in to sync. - Have no enterprise policies. - Have the `app.update.channel` pref set to `release` in the "about:config" page. - Have the [user.js](https://drive.google.com/file/d/1s8Zu8y70ut851CIrXN-mIJigygM5Ym7D/view?usp=drive_link) file saved to your PC. **[Steps to reproduce]:** 1. Open the browser using the profile from the prerequisites. 2. Navigate to the "about:preferences" page and search for the "network" term. 3. Click the "Settings" button from the "Network Settings" section and set up a manual proxy configuration. 4. Navigate to the profile folder and paste the [user.js](https://drive.google.com/file/d/1s8Zu8y70ut851CIrXN-mIJigygM5Ym7D/view?usp=drive_link) file from the prerequisites. 5. Restart the browser. 6. Navigate to the "about:studies" page and observe the active experiments. **[Expected result]:** - The "Firefox VPN for Windows 10 Users - Alpha" is not displayed in the list. **[Actual result]:** - The "Firefox VPN for Windows 10 Users - Alpha" is displayed in the list and marked as active. **[Notes]:** - It seems that if a manual proxy is set, the value of the `network.proxy.type` pref is set to `1`, and according to the information I've found is set to `2` only if the proxy was set using a Proxy Auto-Config file. - Attached a screen recording of the issue.
