I ran firefox.exe with memtrace.dll, using the following command:
drrun -debug -root e:/DynamoRIO-Windows-3.2.0-3 -ops "-stack_size
1024K -max_bb_instrs 512 -max_trace_bbs 512" -client e:/DynamoRIO-
Windows-3.2.0-3/samples/bin/bin/memtrace.dll 0 "" "c:/Program Files/
Mozilla Firefox/firefox"
But I got a "instr_encode error: no encoding found". What should I do?

Run with "-loglevel 1" and find the line at the end of the logfile that shows the instruction it couldn't encode (should say "ERROR: Could not find encoding for: ...").  Then open an Issue (via http://code.google.com/p/dynamorio/issues/list) and paste the info in (including the cmdline you already sent).
