I'm impressed about QNAP efforts trying to proof the mandatory update of OpenSSL is not required. Afraid - your proof is outdated. On one hand, the default was indeed carried forward to the Firefox 4 release version - and is again in stable Mozilla Firefox 5.0 available for some days.
No more excuses - update OpenSSL in v3.5.0!
Advice: just try the way which Moogs mentioned about.
This is not a trick, this is not feasible for normal users - beyond it's torpedizing Mozillas serious security consideratins and remediation attempts.
