I have deleted the macromedia folder in user/library/preferences and the safari plist file , in order to clean and lighten safari .
I don't know if I did right and I would like some opinions on this matter please.
I can always recover the old macromedia folder with Time Machine but I don't believe there is a reason to do so.
Safari is rebuilding those folders with new content.
I would like to delete the Local Storage folder in the user/library/preferences folder , and let safari recreate it but I didn't considered it necessary.
Still I am thinking of doing it.
Any considerations ?
You know that with the reset option from the safari menu there is no way to clean old and unused records of the user/library/preferences/macromedia/flash player folder .
Now I see what you meant by Macromedia... Macromedia was bought out by Adobe.
You can delete Flash cookies. http://machacks.tv/2009/01/27/flushapp-flash-cookie-removal-tool-for-os-x/
Yes, you can delete the contents of the Local Storage folder.
For Safari maintenance, just emptying the cache daily can help.
