Doesn't work at all. Can't connect through any available server. Works fine in Chrome though.

Upd: After 8 months still there.
All the time "Proxy connection error" in Firefox add-on.
On the same computer works normally in Chrome as wel as on phones and tablets in the same network.

Couldn't even install, Chatted with support for 20 minutes. Met with negative aggression re-asking the same questions and transferring me to another agent because his "shift was over" to go through everything again. Awful support.
I asked for a refund. Don't waste your time or $$$,

Very good, I'm working a long time with Surfshark

It works great in all OS Windows Android and Linux.

It is not working. If you login on firefox with your mozila account the extension stop to work, very strange bug.
