HELP! SAFARI AND FIREFOX BROWSER ERRORS

Question

Hello,
Im looking for some help with my Mac Book Pro. For the last two weeks Ive been having serious issues with browser errors. I currently use Firefox and Safari. Certain links do not work properly or not at all. I just click and nothing happens. Here is a sample of what is at the bottom of firefox when i click the link : javascript:WebForm_DoPostBackWithOptions(new%20Web Form_PostBackOptions("ctl00$ctlPagePlaceHolder$Add ToWatchList2",%20"",%20true,%20"",%20"",%20false,% 20true))
Also, The browsers randomly run like crap. I just went to my sharebuilder account and the web page says this:
This page contains the following errors:
error on line 15 at column 66: EntityRef: expecting ';'
Below is a rendering of the page up to the first error.
If I use my other MAC Computer no problems at all. Only this one. I just dont get it.
Another thing. Ive been running repair disk permissions and everyday its correcting what appears to be the same errors?
I just updated to Safari 5 and now have more Issues. Some pages dont even Load.
I have Net Barrier 5 and been running it for about a year. Its like all of sudden everything just starting malfunctioning.
Anyone have any Ideas?

HI and Welcome to Apple Discussions.....
At least part of the problem, especially since the issue is effecting both browsers, is Net Barrier.
You are already running an operating system that protects your Mac against virus and malware, read here: Snow Leopard Has You Covered
You might want to consider uninstalling NetBarrier software.
Another thing. Ive been running repair disk permissions and everyday its correcting what appears to be the same errors?
Those aren't errors, they are "messages"... if run Disk Utility to repair disk permissions, if you see, "Repair Permissions Complete", that's it. Nothing more to do.
Go here for trouble shooting 3rd party plugins or input managers which might be causing problems if they are outdated. Safari: Add-ons may cause Safari to unexpectedly quit or have performance issues
Try emptying the Safari cache from the Safari Menu Bar. Safari/Empty Cache. You can also try Resetting Safari from the same menu.
Web pages include a small icon or 'favicon' which is visible in the address bar and next to bookmarks. These icons take up disk space and slow Safari down. It is possible to erase the icons from your computer and start fresh. *To delete Safari's icon using the Finder, open your user folder, navigate to ~/Library/Safari/ and move this file "webpageIcons.db to the Trash.*
For Firefox from the Tools menu, select Clear Recent History... .
From the Time range to clear: drop-down menu, select the desired range; to clear your entire cache, select Everything. Click the down arrow next to "Details" to choose what history elements to clear. Click Clear Now.
