JIT Inspector is a developer add-on for Firefox that allows you to monitor the metrics for optimization and amount quality of the executed JIT code.
In other words, JIT Inspector displays how much code has run and how well it was optimized: counts the executed individual operations, counts the operations executed entirely in JIT code and the precision of type information inferred for each operation.
JIT Inspector is cross-platform and it works on Mac OS X, Windows and Linux.
· Firefox 12.0 and later
