this ones simple:
this is for broad band connections. I didn’t try it on dial up but might work for dial up.
1.make sure your logged on as actually "Administrator". do not log on with any account that just has administrator privileges.
2. start - run - type gpedit.msc
3. expand the "local computer policy" branch
4. expand the "administrative templates" branch
5. expand the "network branch"
6. Highlight the "QoS Packet Scheduler" in left window
7. in right window double click the "limit reservable bandwidth" setting
8. on setting tab check the "enabled" item
9. where it says "Bandwidth limit %" change it to read 0
reboot if you want to but not necessary on some systems your all done. Effect is immediate on some systems. some need re-boot. I have one machine that needs to reboot first, the others didn't. Don't know why this is.

This is more of a "counter what XP does" thing. In other words, XP seems to want to reserve 20% of the bandwidth for its self. Even with QoS disabled, even when this item is disabled. So why not use it to your advantage. To demonstrate the problem with this on stand alone machines start up a big download from a server with an FTP client. Try to find a server that doesn't max out your bandwidth. In this case you want a slow to medium speed server to demonstrate this. Let it run for a couple of minutes to get stable. The start up another download from the same server with another instance of your FTP client. You will notice that the available bandwidth is now being fought over and one of the clients download will be very slow or both will slow down when they should both be using the available bandwidth. Using this "tweak" both clients will have a fair share of the bandwidth and will not fight over the bandwidth.

force your old add-ons to work in the new versions of Firefox

the cool thing about trying out a Firefox beta is you get all those neat new features before everyone else does. But the bad is that none of your add-ons work anymore.

Thanks to garysimmons on Twitter who pointed to a Lifehacker article from the awesome Gina Trapani on how to force your old add-ons to work in the beta version of Firefox.

Big warning! You're removing a safety net when you do this. Be prepared to deal with bugs, crashes, and security risks if you do this.

OK. Here's how to do it.

Go to the Firefox address bar and type about:config.

Click the button promising to be careful.

You're promising to be careful...RIGHT?

Right-click anywhere on the screen, choose new, then Boolean.

Name your new preference extensions.checkCompatibility Press OK. Then set it to false and press OK again.

Now right-click again anywhere choose New and Boolean and make the name of this one extensions.checkUpdateSecurity and set the value of that one to false.

Great! You've just instructed Firefox not to check the validity of the extension and to tell update security to go take a flying leap.

If you're sure you want to do that, restart Firefox.

Now all your add-ons should load quite nicely. At least if they don't crash the whole browser. Don't forget you turned off the capability to ensure secure updates. So do be careful.

One last tip, several people wrote to me about the Add-on called Nightly Tester Tools. It allows you to use otherwise incompatible add-ons in beta versions, although it doesn't seem to get Firefox 2 add-ons to work in Firefox 3.
