User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.10) Gecko/20100914 Firefox/3.6.10 ( .NET CLR 3.5.30729; .NET4.0E) Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.10) Gecko/20100914 Firefox/3.6.10 ( .NET CLR 3.5.30729; .NET4.0E) For some reason, when the Windows speech recognition is enabled and 'listening', if the Firefox process is selected as the focus point in Windows, CPU usage jumps to 80%-100% when the page moves (e.g. scroll up and down). Nothing has to be spoken, just scrolling the page makes it happen. The same does not occur with other applications. Reproducible: Always Steps to Reproduce: 1. Start speech recognition 2. Say "Start Listening" or press On button. Windows shows Listening. 3. Start Firefox 4. Scroll up/down. Even typing appears to sometimes cause the problem. Actual Results: CPU is super high and FFis super sluggish. Expected Results: Normal operation. No high CPU.
