There are a few unsatisfactory things about the way licensing and credit information is presented in Firefox and Thunderbird (for Thunderbird, the first being that you can’t actually view the licensing information!). The UnifiedLicensingPlan attempts to fix this. Comments welcome, here or in the wiki’s Discussion page.
Can you clarify the intent? I went to the site and looked for changes to the mozi licensing regime but found only discussion about the presentation and probulgation of the licence terms. Are any of the licences and terms changing?
None of the licenses or terms are changing.
