Slow Start-UP, slow tab switching. HELP!

**First of all, i am aware that this topic has been posted before, i just want to know if anyone can give me a personalized solution....please..

Hello! I am truly impressed of your webpage. It actually made me buy a USB pendrive! I'm currently using a lot of portable apps like:

* megairc
* eMule
* Portable Wackget
* Portable Gaim
* Portble Firefox
* HFS
* ...and 18 other apps+Damn Small Linux

Of these apps, my firefox launches the slowest (about 3 minutes). I think it may be because of my extensions which are:

* SearchPlugins Hack
* TabMix Plus
* IE Tab
* Mouse Gestures
* Flashgot
* Ajax Yahoo! Mail
* Gmail Space
* Adblock
* Yahoo! fast picture loading tool
* Yahoo! Mail Notifier
* Adblock Filterset. G Updater
* Fasterfox

BTW, I have Tab Mix Plus' session manager enabled.
Is there any way i can make it launch faster (preferably without installing any extension)?

Also I'm using a Kingston Data Traveler 2.0 512MB and HDtach's Benchmarck test says it's average read speed is 9 MB/s. I've got a P4 2.26 GHz and 512 MB RAM DDR PC3200
Don't know what's wrong! (well, maybe tab mix plus...)

Thanks! Keep on going, the site is really the greatest!
