User Agent: Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.89 Safari/537.36 Steps to reproduce: Open a Webm. Close the page. Try to rename the file (x20) "File is in use" Firefox finally releases memory and let's you rename the file. Actual results: Unable to move webm to new folder or rename webm for an extended period of time, because it's "still in use" in Firefox. As long as 20-30 seconds after closing. Expected results: Firefox releases the memory in a timely manner, allowing me to rename or move the webm without an annoyingly long wait.
Did you test with the other browsers?
Closing in Chrome allows me to immediately rename the webm. That goes around my immediate problem - however that doesn't fix the problem with how FF handles the closing of webm.
