It’s frustrating, but the browser needs to be launched with the global proxy because it doesn’t always inherit the system settings.
One thing you could try is using a browser profile with pre-configured proxy settings. For example, in Firefox, you can create a new profile and set the proxy settings there. Then, just launch that profile whenever you need the proxy.
Another option is to use a VPN that has a “always-on” feature, so it automatically applies the proxy settings system-wide. Surfshark and CyberGhost are good options for this.
