Sidebar Appears in a Browser I Don’t Use

Problem

You only want SupaSidebar to attach to one browser - say Vivaldi - but it also auto-shows and attaches when you switch to a secondary browser like Arc. This is especially disruptive in browsers with their own native sidebar (Arc, Dia), where you end up with two sidebars stacked on top of each other.

Cause

By default, SupaSidebar auto-shows and attaches for every supported browser the moment that browser becomes frontmost. There is no “primary browser” mode - the supported way to scope SupaSidebar to a single browser is to tell it which browsers to ignore.

Revoking Automation permission in System Settings is not a reliable fix - SupaSidebar can still detect the frontmost app and react to it, so the sidebar may still appear.

Solution - Block the unwanted browser

1. Open SupaSidebar Preferences -> Tabs & History
2. Scroll to Privacy Blocklist
3. Click Add to Blocklist -> Block Browser
4. Select the browser you want SupaSidebar to ignore (e.g. Arc)

After blocking, when that browser is frontmost SupaSidebar will not:

• auto-show the sidebar
• attach to or resize the browser’s windows
• intercept Cmd Ctrl T, Smart Save (Cmd Ctrl S), or Smart Copy (Cmd Ctrl C) in that browser
• list its tabs in Live Tabs or its history in Recent Items

The sidebar still works normally everywhere else. Blocking is per-browser, and you can block more than one.

What this is not

• Not a permission revocation. Leave Automation access ON for the browser in System Settings - the in-app blocklist is the correct off-switch.
• Not an app-wide disable. The menubar icon, global shortcuts (Cmd Shift Space etc.), and manual sidebar access keep working in the blocked browser if you trigger them yourself.
• Not reversible only by reinstall. To re-enable SupaSidebar for that browser, just remove the entry from the Privacy Blocklist.
