From The Rumbling Edge:

"I’ve noticed that when there is high I/O activity, viewabout.js sometimes 
throws up a slow JavaScript dialog on startup. Recently, I’ve also noticed 
that the performance of Firefox 4 Beta / RC seems to slowdown significantly 
over time as one uses large numbers of tabs (e.g. more than 80) and one would 
have to restart Firefox. Or disable ViewAbout and the issue seems to go away.

I’ve also experienced lags when opening new windows through JavaScript links 
with the extension."

summary:     Fix a perf issue where ViewAbout will cause performance 
regressions in Firefox 4 beta and RC. Thanks go out to harry for his tip.

A 2.0.1 hotfix was also released to try and resolve this.
