IMDB Pirate

Click on the plugin in the plugins list (you can pin it to toolbar with the cog wheel to make it easier to access), type the name of the show/movie you want to watch, then press search or hit enter. Doing so will take you to an IMDB search list, where you can click on the option you were looking for. When you're on the IMDB page for the search result you chose, click the plugin again and not click "Switch to Vidsrc", this will redirect you to a stream of the content. On this page, if the content is a series, there will be a list option on the top left that will let you sort through different episodes and seasons. On any stream, at the top of the page you will see a server icon, you can switch between (usually) 3 different sources for the content. If the first stream isn't the best quality or is the wrong video, try the other streams. In some cases you may have to refresh after choosing.
