The fact that I am Libyan does not mean that I should make it a paradise to you guys, however, for me, it only seems that the biggest issue right now is the closure of roads every now and then. Safe? yea, I guess during my stay in Tripoli for about two years, it seems to me that if you live in the area starting from Sarraj and all the way to Tajora, you probably will have no issues. I live in Janzour, and, as some problems happen between Janzour and Wurshefana (West Tripoli), it is absolutely safe.
Good luck
