A report by Mozilla, titled "Over The Edge 2.0," reveals that Microsoft is using various tactics to promote its Edge browser, including misleading banners on Bing and pre-pinning Edge on the Windows taskbar. The report indicates that Microsoft hinders users' ability to download or set alternative browsers as default. It also notes that Microsoft's AI tool, Copilot, fails to recognize the default browser when opening links, and data-sharing settings are preselected to ON in regions like the US and India. Despite these efforts, Edge's market share has declined from 13 percent in June 2025 to just over 10 percent, while Mozilla's Firefox has increased from 5.84 percent to 6.44 percent. The Browser Choice Alliance and other browser developers have criticized Microsoft's practices, calling for fair competition.
