Vpn Chrome Proxy
Mohammed Faerber
Changing proxy settings has never been so convenient. Think SwitchyOmega as a modern version of the "Proxy Settings" dialog, designed to be simpler, quicker and more powerful, specially optimized for Chrome.No more digging through the advanced section in Chrome settings. No repeated filling and clearing the proxy config dialog of your operating system. Just tell SwitchyOmega about all your proxies, and enjoy switching with one click on the popup menu. You can also teach Auto Switch to use the right proxy for the right website automatically.This extension replaces SwitchySharp, SwitchyPlus and Proxy Switchy. If you are using SwitchySharp, installing this extension will automatically migrate all profiles and settings for you. As a fallback, you can also export a backup file manually in SwitchySharp and then import the file in SwitchyOmega.NOTE: Please report issues by RIGHT-clicking the extension icon and select the "Report Issue" in the context menu so that I can locate and fix the issue more quickly.Alternative download link (Github): is absolutely free and open source. It does not insert ads into any website. It contains absolutely no malware. It just does proxy configuration, and aims to be perfect tool of that.Disclaimer: SwitchyOmega does not come with any proxy server, VPNs or anything like that. Thus, SwitchyOmega will not magically unblock websites or protect your privacy, unless you instruct it to use a proxy server which does. You should only use trusted proxy servers, because SwitchyOmega can not protect you from bad proxies that inject ads, track you or record your password. And if you don't have a proxy server, you probably won't need SwitchyOmega. Sounds reasonable, right?Privacy Policy: 2.x version features:* HTTP/HTTPS proxy authentication (username & password) is now supported.* More flexible proxy configurations: Fixed servers, multiple SwitchProfile and rule lists.* Reviewing and modifying proxy settings for resources that fail to load.* New types of condition for switching and improvements to the existing condition types.* Optimized performance for both PAC script generating and switching.* Improved user experience in options page and dropdown menu.* Many Bug fixes and improvements. More testing.== Translations ==You can help improve the translation of SwitchyOmega or translate it into your language on Weblate: _source=widgetCONFLICTS: SwitchyOmega will conflict with other extensions trying to control the proxy settings. Such conflicts are caused by the design of the Chrome browser and thus cannot be avoided. When SwitchyOmega has a higher priority, it can be configured to voluntarily give back the control by selecting the [System Proxy] item in the popup menu. Otherwise, you will see a red badge on the SwitchyOmega icon indicating insufficient priority. Re-installing SwitchyOmega should raise its priority, providing a possible workaround.
I am working on Mac and have identical Proxy settings for the System and Firefox browser. However, I am able to see my Firefox traffic in Chrales but I don't see my Chrome and Safari traffic (which use System Proxy Settings). What do I need to do? How can I check the debug this?
Desktop applications that set system-wide proxy don't work really well with VPN. I struggled with Charles & Fiddler because I was under a VPN network and almost all the time I couldn't use any of the apps while on my company VPN So I googled for Web Proxy chrome extension and found Requestly.
In the first case, HTTP, HTTPS and FTP traffic is proxied through the specified proxy server. Othertraffic is sent directly. In the latter case the behavior is slightly more subtle: If a proxy serveris configured for the HTTP, HTTPS or FTP protocol, the respective traffic is proxied through thespecified server. If no such proxy server is specified or traffic uses a different protocol thanHTTP, HTTPS or FTP, the fallbackProxy is used. If no fallbackProxy is specified, traffic is sentdirectly without a proxy server.
A proxy server is configured in a proxy.ProxyServer object. The connection to the proxy server(defined by the host attribute) uses the protocol defined in the scheme attribute. If noscheme is specified, the proxy connection defaults to http.
Match URLs that are IP address literals. Conceptually this is the similar to the first case, butwith special cases to handle IP literal canonicalization. For example, matching on "[0:0:0::1]"is the same as matching on "[::1]" because the IPv6 canonicalization is done internally.
The literal string matches simple hostnames. A simple hostname is one that contains nodots and is not an IP literal. For instance example and localhost are simple hostnames,whereas example.com, example., and [::1] are not.
The following code sets a SOCKS 5 proxy for HTTP connections to all servers but foobar.com and usesdirect connections for all other protocols. The settings apply to regular and incognito windows, asincognito windows inherit settings from regular windows. See also the Types APIdocumentation.

Most UI surfaces in Chrome (including command lines and policy) expect URI formatted proxy server identifiers. However outside of Chrome, proxy servers are generally identified less precisely by just an address -- the proxy scheme is assumed based on context.
Manual proxy settings - proxy resolution is defined using a declarative set of rules. These rules are expressed as a mapping from URL scheme to proxy server identifier(s), and a list of proxy bypass rules for when to go DIRECT instead of using the mapped proxy.
Communication to HTTP proxy servers is insecure, meaning proxied requests are sent in the clear. When proxying requests through an HTTP proxy, the TLS exchange is forwarded through the proxy using the CONNECT method, so end-to-end encryption is not broken. However when establishing the tunnel, the hostname of the target URL is sent to the proxy server in the clear.
Because the connection to the proxy server is secure, requests sent through the proxy are not sent in the clear as with an HTTP proxy. Similarly, since CONNECT requests are sent over a protected channel, the hostnames for proxied URLs is also not revealed.
HTTPS proxies using HTTP/2 can offer better performance in Chrome than a regular HTTP proxy due to higher connection limits (HTTP/1.1 proxies in Chrome are limited to 32 simultaneous connections across all domains).
SOCKSv4 is a simple transport layer proxy that wraps a TCP socket. Its use is transparent to the rest of the protocol stack; after an initial handshake when connecting the TCP socket (to the proxy), the rest of the loading stack is unchanged.
When using a SOCKSv4 proxy, name resolution for target hosts is always done client side, and moreover must resolve to an IPv4 address (SOCKSv4 encodes target address as 4 octets, so IPv6 targets are not possible).
In Chrome when a proxy's scheme is set to SOCKSv5, name resolution is always done proxy side (even though the protocol allows for client side as well). In Firefox client side vs proxy side name resolution can be configured with network.proxy.socks_remote_dns; Chrome has no equivalent option and will always use proxy side resolution.
A QUIC proxy uses QUIC (UDP) as the underlying transport, but otherwise behaves as an HTTP proxy. It has similar properties to an HTTPS proxy, in that the connection to the proxy server is secure, and connection limits are less restrictive.
With the above configuration, if the proxy server was unreachable all requests would fail with ERR_PROXY_CONNECTION_FAILED. To address this we could add a fallback to DIRECT by launching using --proxy-server=" :8080,direct://" (note the comma separated list). This command line means:
Most platforms' manual proxy settings allow specifying a cleartext username/password for proxy sign in. Chrome does not implement this, and will not use any credentials embedded in the proxy settings.
Matches URLs that are IP address literals, and optional scheme and port restrictions. This is a special case of hostname matching that takes into account IP literal canonicalization. For example the rules [0:0:0::1] and [::1] are equivalent (both represent the same IPv6 address).
The rule name comes from WinInet, and can easily be confused with the concept of localhost. However the two concepts are completely orthogonal. In practice one wouldn't add rules to bypass localhost, as it is already done implicitly.
Say we have have configured a proxy for all requests, but added a bypass rule for 192.168.0.0.1/16. If we now navigate to (which resolves to 192.168.1.5 in our setup) will the browser connect directly (bypass proxy) because we have indicated a bypass rule that includes this IP?
The bypass rule in this case is not applicable, since the browser never actually does a name resolution for foo. Proxy resolution happens before name resolution, and depending on what proxy scheme is subsequently chosen, client side name resolution may never be performed.
This concept of implicit proxy bypass rules is consistent with the platform-level proxy support on Windows and macOS (albeit with some differences due to their implementation quirks - see compatibility notes in net::ProxyBypassRules::MatchesImplicitRules)
Why apply implicit proxy bypass rules in the first place? Certainly there are considerations around ergonomics and user expectation, but the bigger problem is security. Since the web platform treats localhost as a secure origin, the ability to proxy it grants extra powers. This is especially problematic when proxy settings are externally controllable, as when using PAC scripts.
If you want traffic to localhost to be sent through a proxy despite the security concerns, it can be done by adding the special proxy bypass rule . This has the effect of subtracting the implicit rules.
