pjpw2320,
First, welcome to the forum. B)
I am curious about what seems to be the vastly superior memory management abilities of CometBird compared to Firefox.
Now, seems like both you and me are fortunate, because when speaking about CometBird memory performance, a vast majority of users complaint of it. They used to say that CometBird eats RAM and/or CPU. That is not my case, as CB works really good for me. And for you too, according to your words.
However, I can’t affirm that CometBird is actually “superior” to Firefox. I can’t 'cause I have different add-ons in each of these 2 web browsers, and one has more installed add-ons than the other. In fact, CometBird uses a little bit more of RAM than Mozilla Firefox, in my particular case. Here you have an example — This is the RAM that CB and Firefox use when they’re just opened with no opened tab at all (in other words, the so called about:blank URL).

I repeat it: I can’t compare fairly both web browser’s memory management, since —and here’s another example— while I have 10 plugins installed for being used with Mozilla Firefox, CometBird loads 11 plugins (the same 10 that Firefox uses + BitCometAgent).
Anyway, I’m gonna give you a little cheat to make any Mozilla Firefox based application use less RAM when it’s in a passive state.
■ 1. Run Mozilla Firefox (or CometBird, of course) and at the address bar type about:config and hit Enter. You might see a warning message. If yes, just click on the I’ll be careful, I promise! button.

■ 2. You’ll see a long list of items. Access the contextual menu on any blank space (right-click if you have the mouse configured for right-handed usage) and select New > Boolean. The New boolean value dialog window will appear.

■ 3. Enter config.trim_on_minimize as preference name and click on the OK button. Then, select true as value.
You’re done! Now, open the Task Manager and open several tabs in the web browser that you did this modification. Trace its RAM usage at the Task Manager window and minimize the web browser. You’ll amaze about how it goes down so quickly! Now you’ll be able to run simultaneously both web browsers without have to worry about the RAM. :o
I am currently using FF V3.6.13.
FF V3.6.13? Unless you are using a Mozilla Firefox 3.6.13 release candidate, currently the last Mozilla Firefox stable version is 3.6.12. If no critical bug is discovered in Firefox 3.6.12 within the next few days, Mozilla Firefox 3.6.13 will be released on December 9, as originally planned.
CometBird is also the only alternative Mozilla based browser that has been able to run all my FF extensions so far, especially the Google Notebook extension.
Totally agreed. I also tried Flock (unless up to 2.6 which is still based on Mozilla Firefox —3.0 beta is based on Google Chrome—) and Wyzo. These two Mozilla Firefox based web browsers really disappointed me, as their project developments are pretty slow and not clear enough. I sent several suggestions and bug reports to both teams and they seem to don’t care at all, so I thought F**k them! and quit.
The CometBird Development Team is going in the opposite direction. I reported a bug some weeks ago and they fixed it in record time. That’s real usercare, fellas!

Best regards,
