Version 1.3 — release notes:

Fixed: The fullscreen effect was bleeding into other open tabs when switching between them, since Firefox's fullscreen applies to the whole window, not a single tab. The extension now detaches the TradingView tab into its own dedicated window the moment it loads, and only fullscreens that isolated window — your other tabs and windows are never touched.

Fixed: Floating restore button was still hard to see — switched from a translucent dark button to a solid amber circle with a border, so it stands out clearly against TradingView's dark theme instead of blending in.

Version 1.1 — for AMO's "release notes" field:

Fixed: switching between tabs no longer resizes/reflows other open tabs — the toolbar now only hides or restores when the TradingView tab itself opens, navigates away, or closes.
Fixed: floating restore button was too transparent to see — increased its default opacity for better visibility.
