Not too exciting. I use some shell aliases, “cvsdiff” is “cvs diff” with my regular options, “cvsdiffb” is “cvs diff” with the “brief” option so I get a list of files that changed and not the changes themselves. “ffdebug” is “gdb” with “NO_EM_RESTART=1″ at the beginning, which stops Firefox from doing extension manager restarts when I want to debug it.
