A handy tool Rated 4 out of 5 stars
Even though it doesn't really excell in anything in particular, it does work of several other extensions at once (there are several restarters, memory indicators etc.), and it nicely integrates them into a combined action. Overall it's quite useful, but I believe one feature requires some attention, and it's one which has a potential to be the most useful - the "Minimize memory..." one. While having automatic memory use minimization is practically the Holy Grail with Firefox, I've discovered a problem with this implementation. Namely, I've had strangely high Firefox CPU usage on occassions, and I think that feature is the culprit. I've started monitoring GC and CC activity with the MemChaser extension, and noticed that both Collectors are constantly activated in intervals less than a second long. Investigating this, I've noticed the MR's icon is red, and I presumed it might something to do with its Memory minimize functions (which I wasn't sure what actually does until then). When I raised the MR's threshold to a higher value, the CPU use decreased and the Collectors intervals rose to several seconds or several tens of seconds. So I guess the Memory minimize works too zealously in the attempt to free memory that it has the adverse effect on CPU usage, and I recommend you relax it a bit. I'd give you a lesser rating for this, but since the tool is quite useful, and the threshold is adjustable (it seems that even this way an ideal one can be found, where the memory is always freed successfully so it can stop) and Memory minimize can be turned off anyway. If you fix the Memory minimize not to be so aggressive that FF starts using 100% of CPU (core) as it does now, you'd deserve a 5-star rating.This review is for a previous version of the add-on (1.11.1-signed.1-signed).
