Article summary

Firefox displayed a pop-up ad for Mozilla VPN over an unrelated page, interrupting the browsing session and disabling the rest of the Firefox UI until closed. This incident was reported by multiple users on Mozilla support communities and Reddit. The ad was part of an experiment that was quickly rolled back after user complaints. The issue was resolved, but it raised concerns about Mozilla's advertising practices.

What commenters say

• Mozilla's decision to display ads in Firefox is unacceptable and erodes trust in the browser.
• The company should not have an advertising channel in the browser and instead offer opt-in newsletters or paid versions.
• Some users find ads in the 'what's new' tab or other designated areas to be less problematic than overlay ads on unrelated sites.
• Forks of Firefox, such as LibreWolf, offer privacy enhancements and can avoid such issues.
• Mozilla has a history of similar incidents, such as the Mr. Robot debacle, and has not learned from its mistakes.
• Advanced privacy settings can sometimes break websites, but this is preferable to ignoring user preferences.
• Mozilla's experiments and advertising practices are seen as a betrayal of the browser's original principles and values.
