Put simply: it causes a massive memory leak within an hour if I work on a Symfony project, and I don't use any of the features that it provides. I've looked through all of the menus and can't seem to see an option to disable support for it.
Has anyone attempted or managed to remove this module from the IDE? I quite like NetBeans, but on the rare occasions when I need to work with a Symfony project it's causing me quite a headache.
Go to the Tools, Plugins menu, there you can deactivate or uninstall the installed plugins (PHP Symfony Framework is one of these).
