response lag is annoying
I like to keep a bunch of FF windows open ... 18 at the moment ... each window has 4 -10 tabs open. But this causes a lag or latency. The window and tab that I am currently using often freezes for 5 or 10 seconds while I am typing or clicking. It will even freeze while I am scrolling down a page, then I have to wait until it focuses on me again.
Other programs running on my machine (under XP-Pro) at the same time do not have this lag.
I believe it is a FF problem because when I look in task manager, it is FF that is hogging the processor cycles.... even when I am not using any part of FF.
Can I find out if some particular tab is causing this? How? Is there some way of monitoring FF like task manager monitors Windows?

Sorry, there is no tool to monitor and discover which particular Firefox tab is hogging CPU cycles. Unlike IE, all Firefox windows run in the same process, and unlike Chrome, all tabs run in the same process. Mozilla is working on changes for future versions of Firefox to run separate processes. Currently, the only thing that runs in a separate process is certain plugins (OOPP = Out-of-process-plugins in Firefox 3.6.4+ versions).
You might try increasing the time interval for Session Restore backups.

Default is 10 seconds - I changed it to 50 seconds on WinXP / Firefox 3.6.x, and that solved a periodic "hanging" when I was typing in a textarea.
You could try disabling that Zone Alarm Spy Blocker plugin and the related Toolbar extension - ( http://kb.mozillazine.org/Problematic_extensions ) - and see if that lessens the problem.
Beyond that, you could try the basic extension troubleshooting to see what else might be contributing to that problem.
