During the years its severity has grown along the ever broader use of flash and other plugins. Simply put, it makes Firefox a bad product. Since key handling inside/outside plugin objects is a delicate matter, people could discuss the theoretically best solution forever - instead of changing the behaviour to something better. Here is a workaround for one of the most annoying results of the bug: Problem: When scrolling, it stops when cursor happens to be over a YouTube video. Solution: Never pass scroll events to a non-focused plugin object. Please include this enhancement in Firefox 4. Reproducible: Always Steps to Reproduce: 1. Load a Youtube video page. 2. Give the plug-in focus by clicking Play. 3. Hover the plug-in and scroll. Actual Results: No scrolling. Expected Results: Scrolling as normal.
