Why use SwitchProxy?
If you work with more than one proxy on a regular basis, you probably know how annoying it is to keep track of them; not to mention the number of clicks it takes to switch between.
SwitchProxy is a Mozilla tool you can use to organize all your proxies. You can add, edit and remove them from a single master list. When you need to use one, just select it from the list and click apply.
for mozilla,firefox and thunderbird browsers
