Does Google Chrome have a FoxyProxy equivalent?
Solution 1:
Proxy Switchy! is pretty similar. Annoyingly, on Linux, it requires a Gnome or KDE environment.
Don't confuse it with Proxy Switchy!中文汉化版 (I haven't looked into it at all). Another option for Chinese speakers in Switch Proxy.
Solution 2:
According to FoxyProxy's website, they do indeed have a version for Google Chrome. You can find the extension on the Google Chrome webstore.
