Description
The issue is related to insufficient warning about potentially dangerous actions when downloading certain file types. Specifically, the executable file warning was not presented when downloading files with .msix, .msixbundle, .appx, and .appxbundle extensions, which can run commands on a user's computer. This issue only affects Windows operating systems, with other operating systems being unaffected.
Recommendations
For Firefox versions prior to 119, update to version 119 or later to resolve the issue.
For Firefox ESR versions prior to 115.4, update to version 115.4 or later to resolve the issue.
For Thunderbird versions prior to 115.4.1, update to version 115.4.1 or later to resolve the issue.
As a temporary workaround, consider avoiding the download of .msix, .msixbundle, .appx, and .appxbundle files until the issue is resolved.
