When browser closes, many "plugin-container.exe" processes are started

u2t4c6s8n

When Firefox start, there's only one "plugin-container.exe" process. Instead at closing, many plugin-container.exe appear gradually taking up memory. So closing is quite slow. Is it normal?

That may be caused by using Delete browsing, search and download history on Firefox to clear the cookies. Firefox 4 tries to clear the Flash cookies (LSO) as well and starts the plugin-container processes to accomplish that.

I am using Firefox 4.0.1 (win32, en-US) on Windows XP Professional SP3 (i386, ENU). I am able to solve this problem by renaming the "XUL.mfl" and "startupCache.4.little" files (after closing Firefox first of course). Search for the files in your system (C) drive, making sure to search for hidden files and folders, then rename the files to different names. After renaming the files, try relaunching Firefox and using the "Clear Recent History" function (with "Cookies" selected) for a few times, and hopefully the problem should be solved.
