Not every box has it available, but some of them were paging to update to 10.9.4 this morning so I ran it on all the boxes. Also restarted FF with some additional environment variables that I should have put in place yesterday with the custom build. DYLD_INSERT_LIBRARIES=~/Desktop/FirefoxNightlyDebug.app/Contents/MacOS/libdmd.dylib LD_LIBRARY_PATH=~/Desktop/FirefoxNightlyDebug.app/Contents/MacOS/ DMD=1 ./Desktop/FirefoxNightlyDebug.app/Contents/MacOS/firefox
3 or 4 of the boxes already had the 9.4 update. The rest have been updated. At the end of the day we should have plenty of memory results to submit. Even if nothing has fallen over there will be leaked heap spread over all the ambient machines, like a sauce.
