Firefox going slow?

I have always been the culprit of keeping more than 10 tabs open in my Firefox. So, 200MB+ memory usage and slow behavior of firefox is something that I can simply not avoid. And Firefox memory management still has lots of scope improvement (Though it has improved tremendously from previous versions).
But 300MB+ memory usage? And 50% CPU usage?? And even filling a simple form got too slow.
Then I remembered reading quite a long while ago (Firefox 1.0 days) that some of the firefox extensions can be problematic and cause memory issues with firefox. I did install quite a few extensions so I decided to take a look.
Here is the Mozilla Page which list all the problematic extensions. In my case, it was Cooliris that was causing trouble. I disabled it, and my firefox is up working again.

Is your Outlook slow?

I use MS Outlook 2003 to read my company emails. Recently, it had started taking a long time in starting up. It also became sluggish and even opening an email would take a long time.
Some friends suggested that the my OST has grown too large. At 600MB, it certainly is big but isn't outlook supposed to handle upto 2 GB sizes easily.

Some googling got me to this post and introduced me to SCANPST, which is an Inbox repair tool installed by default with Microsoft Office but not available in any of its menus.

I just ran SCANPST from C:\Program Files\Common Files\System\MSMAPI\1033 ... It found and repaired some 1700 problems with the OST file!!!
Now my outlook is as snappy and responsive as before.
