Open issues/risks


Stage 1: Definition

1. Feature overview

Our current experience when a plugin is missing is pretty abysmal, and rarely works for anything else than a very small set of plugins. We want to fix the experience for the small set of plugins that have a lot of users, and stop pretending to supply an auto-detect service for the others.

This feature falls primarily in the Experience category (from the "Discover, Experience, and Connect" vision statement.)

2. Users & use cases


3. Dependencies


4. Requirements

  • Ability to detect and point to relevant locations for the major plugins
    • PFS does this
  • Mozilla needs to host permanent redirect URLs for this, so we can change quickly, should downstream providers suddenly change their URLs or similar
    • PFS basically does this.
  • bug 268936 - It should be possible to say "Don't ask me to install this plugin again"
  • We should never imply that installing a plugin is absolutely necessary for the browser to function (like we kind of do today), but rather that plugins are required for certain types of content
  • bug 678707 - We should label which plugins you'll end up downloading/installing in the location where we show the "Missing Plugin" message. Right now, you don't know until you go ahead and start the process
  • bug 264254 (essentially WONTFIX) - We want to stop using Plugin Finder Service, and instead hardcode the small list of plugins we care about to simplify the code and maintenance burden
    • We are maintaining plugin data for plugincheck anyways
