Socks5 Proxy Support

loomes

Hmm im a new Vivaldi User (stable Version). Im coming from Firefox. And i also use alot of Socks5 Proxys.
And this works great in Vivaldi with SwitchyOmega (also Foxyproxy but the development stopped for Chrome Browsers and the existing version is very old). Strange that this wont work for you?

What OS are you using?

I'm on Windows 10 64-bit and I get this error when I try to visit any site:
ERR_SOCKS_CONNECTION_FAILED

I use the Backup/Restore options in SwitchyOmega. If I import those same settings into Firefox, it works fine. Again - both are running Windows 10 64-bit.

Yes im also on Win10 64bit. I connected to my Socks5 Proxys with plink.exe (over ssh) so i have them on 127.0.0.1 with different ports.
This added to SwitchyOmega works 100%.

Edit:
Tested with another Socks5 in my Network (3proxy over stunnel on a Debian Machine), this works also.

That is a major difference in our setups then. I imagine you can skip the SOCKS5 authentication in the browser since you have an SSH tunnel connection open. As you can see, the authentication fails in my example. At any rate, you're working around limitations in the environment. If that works for you, that's great. I feel the browser should be independent in this respect.

I don't know if Linux or MacOS work with respect to SOCKS5. It may work. For me, if it fails in one scenario, it fails on all. I use my browser for testing purposes at work as well as personal use cases and don't want to maintain different browsers, different configs, nor different hacks . I find one setup that works and apply it to everything I do. The more hacks and steps I have leave more layers of diagnosis/troubleshooting/triage when it fails, and I have to mimic the more common real world scenarios in my testing.

OK, you use Socks5 with Authentication. Yes thats different from my Scenario.

@UncaughtException does the following trick work?
It's a year old so I don't know, if it's still true today as I don't use it myself...

Chrome, Internet Explorer, Edge only support SOCKS4.

Firefox supports 4, 4a and 5, but not with auth (although I understand there was a patch submitted).

If you want to use a web browser via SOCKS with auth, you could use something like Proxifier to divert the browser connections, or the AutoText SOCKS client (which supports GSSAPI authentication).

I was not familiar with Proxifier but I did some brief research. Here's two problems with Proxifier:

You must pay for it after the 30 day free trial
I did not see a Linux offering mentioned (Windows and MacOS are supported)

At this point though, I am going to stand firm that Vivaldi needs to natively support SOCKS5. It's obviously your call if that's going to happen or not, but as I mentioned above, I'm looking for minimal hacks to get it working (ideally none) as I use my browser for work and personal purposes and it's much easier for me to install it and use it on multiple platforms. You could really get the upper hand on other Chromium based browsers by doing this.

Being able to access SOCKS5 just within my browser (ie not needing to mess with the OS-level configuration) would be great. Right now I have to use firefox for this.

@LonM For me, https://github.com/henices/Chrome-proxy-helper works surprisingly well. But maybe I miss a use case.

@jumpsq Thanks for that link. I'll check it out.

So, how can I use my SOCKS5 proxy login credentials?

--proxy-server="socks5://myproxy:8080" 
--host-resolver-rules="MAP * ~NOTFOUND , EXCLUDE myproxy"

@jumpsq Sadly it don't work.
