Ok guys, I don't know why you only have GLITCHES browsers. That is so strange!
I only downloaded "PORTABLE" browser. I think you did adding too much Extensions (add-ons) and it cause your browser performance slow down and eating much memory.
I only have one Add-on "Adblock Plus (Beta)1.2"
Adblock Plus (Beta) 1.2:

So, here is my picture.

-----------------------------------------------------
The reason, you are having problems:
1. Make sure to have Anti-Virus and check it's UP-TO-DATE (I'm using Avira FREE AntiVirus, so please disabled Windows Defender(if you do both at the same time, it will slow down your computer)
2. Make sure to have a good Firewall (I'm using Comodo Firewall, so I disabled built-in Windows Firewall)
3. Make sure to check your driver UP-TO-DATE (ex: graphic card, BIOS up to date, Audio, and so on).
4. Make sure to check Windows Update to complete all installed (New update on last Tuesday, April 10, 2012).
5. Make sure to check your software/programs UP-TO-DATE (Flash player, Shockwave player, and so on)
