Vivaldi is a Chromium-based browser whose cookies use the standard Chromium encryption scheme, but under its own key-store entry: the "Vivaldi Safe Storage" Keychain account on macOS, and the "com.vivaldi.Vivaldi" xdg-desktop-portal application id on Linux (KWallet/portal key storage). Add a self-contained browser/vivaldi package mirroring the Edge finder: per-OS profile roots (~/Library/Application Support/Vivaldi on macOS, ~/.config/vivaldi[-snapshot] on Linux, %LocalAppData%\Vivaldi\User Data on Windows/WSL) and a finder that sets the portal application id so the Linux KWallet/portal key lookup resolves. Registered in browser/all. Verified end-to-end on macOS: decrypts real github.com cookies from a live Vivaldi profile.

Add Vivaldi browser support
Vivaldi is a mainstream Chromium-based browser that kooky doesn't currently detect. This adds a self-contained
browser/vivaldipackage and registers it inbrowser/all.Why it's more than a Brave clone
Vivaldi encrypts cookies with the standard Chromium scheme, but stores the encryption key under its own entry:
Vivaldi Safe StorageKeychain account. Derived automatically fromBrowserStr = "vivaldi", so no extra config is needed there.com.vivaldi.Vivaldi. This repo'sinternal/chrome/chrome_linux.goalready has a KWallet fallback branch commented "used by Vivaldi, newer Chromium" that readsportalAppIDValue(); the finder now callsSetPortalAppID("com.vivaldi.Vivaldi")so that path resolves.Profile roots
~/Library/Application Support/Vivaldi~/.config/vivaldiand~/.config/vivaldi-snapshot(+ Windows roots under WSL)%LocalAppData%\Vivaldi\User DataThe finder mirrors the Edge finder's structure (per-OS root files in-package + a finder that customizes the store), so it stays consistent with the existing Chromium-derivative pattern.
Verification
go build ./...,go vet ./...,go test ./...pass.browser/vivaldifor darwin, linux, windows, android, ios, js/wasm, aix, freebsd.go run ./cmd/kooky -b vivaldi -d github.comdecrypts real cookies from a live Vivaldi profile (correctlogged_in/user_sessionvalues).I don't have a Linux/Windows machine to verify those key stores at runtime — the paths and the portal id follow Vivaldi's documented locations and this repo's existing Linux key-storage code, but a maintainer with those platforms confirming would be welcome.
Closes #115
