Security, Video lock up fix.

K-Meleon is getting kind of old these days, but, that's not bad.
Just needs a tuneup as the Internet seems to be changing & leaving
K-Meleon behind.

It took me 11 times to find the bug in my version of KMdb to stop
Youtube vids from locking up everything.
Note Turn:
setpref(BOOL,"javascript.options.jit.content",false);
setpref(BOOL,"javascript.options.jit.chrome",false);
setpref(BOOL,"network.prefetch-next",false);
setpref(BOOL,"security.enable_java",false);
Also it helps to keep an tab open.

"javascript.options.jit" is also an security issue.

The main part is the settings in about:config
You can put in the settings your self or download the KMFILES.
The info is here:

For the main part it is settings like:
setpref(INT,"network.websocket.max-message-size",2000000);
setpref(INT,"offline-apps.quota.max",2000);
This does not make a lot of room for an virus, it helps.

There are others like.
setpref(BOOL,"layout.css.visited_links_enabled",false);
You can test it here:

Or if there might be a memory leak. Turn off your memory!
setpref(INT,"browser.cache.memory.capacity",0);
And turn on, or off your disk cache.

Anyway you see it, K-Meleon is coming back!
Have fun!!

edit: dramatically improve performance only for 1.54.

1.6 is enough fast already.
