Independent proxy settings option inside Vivaldi than depending on some other or system proxy?
Why not Vivaldi develop a tab where in one can set Vivaldi's proxy settings inside it.
It remains independent of the other settings.
It will give user option to keep only this browser in one particular proxy.
Also, once one of the computers was affected by virus and its proxy inside IE was changed to some other site instead of a regular proxy. so net was not connecting. Only browser that helped was Firefox, as it allowed manually over-ridding the proxy back to original one and allowed antivirus program to be downloaded.
Kindly develop self-dependent proxy option. Its very useful.
