As others have stated in reviews here, this extension does not work properly - it causes delays or completely fails in accessing sites, both problems of which disappear when you pause or turn off the extension. Before I am told to contact support, I have already done that and was advised to reinstall the extension, which I did, with no change. I was then asked why I was using the firefox extension and it was suggested I should just use the desktop VPN client - for a couple of reasons I do not want to do this. My next step will be to try an alternative VPN if Surfshark can't fix this. This is a relatively recent problem so someone has done something to mess things up - when you find them, can you please tell them to undo what they did.
