Yes and no. If you are downloading something using Mozilla, link prefetching will be delayed until any background downloads complete. For example, if you load a bookmark group (which opens several tabs), any prefetch requests initiated by one of the bookmarked pages will not begin until all of the tabs finish loading. If you are using another application which uses the network, link prefetching in Mozilla may compete for bandwidth with the other application. This is a problem that we hope to address in the future by leveraging operating system services to monitor network idle time.
