I have around 2600 tabs. This extension seemed promising at first; it didn't cause a massive CPU spike every time I opened/closed a tab, as opposed to the last tab counting extension I tried, which would instead freeze my browser for a few seconds. HOWEVER: found out later that it was causing the startup time for my browser to go from about 30 seconds to 52 minutes. Browser would show nothing but a black screen, eating 100% of a CPU core constantly, for 52 minutes before I could do anything in it. No thanks. Might be good for less tabs (although at that point other extensions will work fine too)
