The other issue on my MBP (2007 Core2Duo running Mavericks) is, that the autotype works to fast for the browsers.
When starting the autotype the first field (usually username) is typed still correctly but the next field (Password) seems to missing some of the first characters.

I do a workaround by adding the {DELAY 150} after the {TAB} for each used entry, which is a little annoying to do this for all other entries in advance.

Is there eventually a feature to give the tab generally a delay?
(may the MBP is just simply to slow)
