Works like a charm but update description! Rated 5 out of 5 stars
Works like an absolute charm as long as you give yourself no more than 5 minutes to learn the script, which I know most of you will find an absolute age, impatient, with your trousers round your ankles...
But, author, PLEASE update your title and description - searching for "firefox proxy" this never turns up in the results and it should. One never remembers the thoroughly unimaginative name "MM3-ProxySwitch".
Many thanks for your excellent assessment and your suggestion on a more meaningful name.
We have adapted the description on your note.
The descriptive name Proxy Switch is found in the add-ons.
