Great tool, simple and versatile.

I've used it for years. Cute little thing. Clean, and simple to use. The developer's english ain't too good, but I can put up with that! :)

I like proxyswitch. It's simple and easy to manage. But I wonder why this extension suddenly requires rights to "Access your data for all websites". Can you explain that? Browser plugins can create serious security issues and be a target for people trying to snoop on lots of users...

YEs it is great to have it working again as a webextensions addon, I hope we could get some of the old functionality even if we have to do some workaround or manual text editing (like the testURL setting, and shortcuts ).

Забиваю в конфигуратор одним из пунктов
[ProstoVPN.org
url=https://antizapret.prostovpn.org/proxy.pac
]
При сохранении или проверке получаю выделение серым и зачеркивание названия пункта и ключевое слово "url". Соответственно, этот пункт не появляется и не может быть выбранным в выпадающем списке. Firefox 59.0a1 x64.

Работает, всё отлично! Спасибо!

It's simple! It doesnt query me "access to all pages' data" as other proxy-switchers. It works with socks :)

If the proxy status is off, it should turn to "on" automatically when a proxy is selected . Instead of turn the status to on manually , so convenient, reduce two mouse click. But just keep the "off" state(use the broswer's setting)-- when not using the proxy.

Excelente, until last week.
Same commentaries than other users. I copy it from other:
---
I love this extension for years for its simple and convenient usage at all aspects (GUI, configure syntax, etc), comparing to other similar extensions. However, for the beta version 2017.461 which is migrating to WebExtension technology, is not as convenient as before (the one using XUL).
1. In before if I want to switch off or switch on the proxy, simply clicking the extension button once is enough. Now it requires two clicks - click once to drop down the menu, then click once to select the menu entry of switch on/off.
2. In before, there was a down side triangle which will drop down the candidate proxies for selection once clicked. If I select one pre-defined proxy, the proxy is selected **and switched on automatically**. Now in beta version, selecting proxy and switching on/off are separated operations. I need one more click if switching from proxy-off mode to with-one-proxy mode.
3. the icon/button in the toolbar is not as bright as before when proxy is switched on, that is confusing of whether the proxy is on or off.
In one word, I prefer the old way to interact with MM3 Proxy Switch. I am not sure if current behavior is due to the WebExtension technology. However, if possible, I wan to see my favorite extension can have the same way of interacting with end user as before, which is more convenient, I think.

Very useful and convenient tool, but it doesn't support the modern firefox feature -- multi-process usage to effectively distribute the load.

if a gui for input proxy setting would be perfect.

Comparing with the well-known competior it wins for me.
It has no artificial limitations for local IPs/domain names, which are especially useful for SeaMonkey (no proxy for mail servers).

The config is the quickest and easiest, all in one window.
IMO monospaced font will do better.

It lacks proxy select based on URLs, but this feature is insecure so I don't use it.

I'd preferred more flashy icon in order to see more easily if it enabled, but it can be modded by user.

I've been using this addon for many years and the plain-text configuration is simpler by far than that of any dialog-driven proxy addons. However I now need glob-based url matching and am at a crossroads.

Works perfect and uses copyable plain text configuration instead of stupid dialogs. Thx!

love it .. work perfect with FF 18.
Thank you

Works very well in Firefox 17 and lower, but is completely broken in Firefox 18; not any automated switching method works any longer, so the last entry is always selected. This could be because proxy handling was changed in Firefox 18.

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".

its steal your proxys and post them somewhere!!!!

It´s not bad but I think it is too complicated to configure it.
Also I didn´t get it to work right.
So for now only 3 /5 Stars.
Edit:
I got it working now,some other proxy add-ons negated its effect...
Anyway I like how easy it is to change the settings and also that you can change the homepage.
Tested on Win7 / FF15 Beta 5
5/5 Stars

It can't save config on Ubuntu 11.10's Firefox, so it can't work.

Use it to switch between work LAN proxy and 3G connection (no proxy).
Works brilliantly, great time-saver.

Nice tools. Has some quirks, but generally nice.
Version 2011 cannot load config file. Go to author site an use version 2011.100 to solve this problem. (http://www.proxy-offline-browser.com/ProxySwitch/)
