Please fix your update page! Rated 4 out of 5 stars

I believe in Foxyproxy but that update page needs to be fixed. Even the part about clicking on how to get rid of it goes nowhere. You are better than that.

This review is for a previous version of the add-on (3.0.1). 

how to prevent display of update page

The links goes to the FAQ. It is explained there:

How can I prevent display of the release notes after upgrading?
You can disable the display of the release notes after upgrading FoxyProxy by doing the following:
Enter about:config into the address bar
Type extensions.foxyproxy.last-version into the filter
Double-click the item
When prompted to "Enter string value", enter 999 or any other very high number.
You will never see the release notes page again after upgrading. To undo this, perform all of the above steps but enter 0 for the last step.

Very Good! Rated 5 out of 5 stars

I really don't need proxies every day but I tried several and I believe in this one the most and put it in my "Apollo! Pack" collection and for those situations when you need extra privacy this is probably the best one.
