Review for Live HTTP Headers by anonything
Rated 2 out of 5 stars
I typically have between 30-150 tabs open at any given time. Most of the time things run smoothly, no issues with lag or stalling. Installed this addon and everything (entire system) became horridly sluggish. Memory consumption and cpu load was twice what I typically see when this addon is disabled.
