Adblock slowdowns SeaMonkey

[IZh]

Hi.

I have SeaMonkey v 2.24 and ABP v2.5.1.

After some time of browsing pages, SeaMonkey becomes more slow.
Particularly, opening a new window took about 1 second link, etc.
Even opening add-ons manager is slow.

But if i disable/enable ABP, all begins to run fast (for some time).

Is it possible to find where SeaMonkey spends lots of time?

Other installed add-ons are:
- ChatZilla 0.9.90.1
- DOM Inspector 2.0.15pre
- FB2 Reader 0.24
- Ghostery 5.1.2
- JavaScript Deobfuscator 1.6.4
- NoScript 2.6.8.18rc1
- Organize Status Bar 0.6.5
- Session Manager 0.8.1.0
- Speed Dial 0.9.6.16
And plug-ins:
- Shockwave Flash 12.0.0.70
- Silverlight Plug-in 5.1.30214.0
- VLC Web Plugin 2.1.0.0

After using browser for some time, it seems to eat 100% CPU (one core).
There are dozen of active threads. The most active is the main thread. I have captured several random stack traces from sysinternals' procmon:
