ACS:Resource not found or internal server error

Question

                   Hi,
I install the lastest patch on my ACS server 5.3, (5-3-0-40-9),but recently i often find an error page when I login on my server ,and also i can not get the necessary message,it happens frequently but not always.
when it  happens, i check the application status and  all processes show running. at last ,i have no idea,i restart my server and it shows normal,
when i uninstall the patch,it works fine.
can you tell me how to deal with this problem?
waiting for your replay,thank you.

It looks more like a browser compatibility issue that is known to happen with newer versions of Firefox. Unfortunately, ACS 5.x is not currently compatible with those as it wasn't tested (because those versions weren't available at the time of the ACS release) and we need to stick with the supported version until we come out with a new ACS version that supports the newer browser versions.
There is an enhancement filed as well.
