How to fix firefox memory leak and slowness on the Mac
As a developer, I run Firefox all day long. Then I began to notice that Firefox would get progressively slower, to the point where it wouldn’t want to move anymore. So here is how you can diagnose and fix the problem to make Firefox faster:
1) open “Activity Monitor”
2) Notice how on mine Firefox is reaching 1GB of memory?
3) Close Firefox and whatever else you think is being a memory hog.
That’s it. It will be faster. I recommend doing this 2-3 times a day.
By the title of your post (and it’s high search rank in my google search) I was hoping you actually had a fix for Mac Firefox. But restarting often is not a solution. Besides, after just 1 hour with 3 tabs open (1 being Gmail) the memory got up past 600MB and is concerning a far amount of CPU! I don’t want to have to restart hourly.
It makes me sad that I have to use Chrome and their inferior dev tools since I just can’t put up with such a slow, bloated browser any more.
