Image → Photopea reliability
• Works on restricted / protected sites (including addons.mozilla.org) where images used to fail because of CORS.
• Stronger image extraction (multiple download strategies + tab capture when needed).
• Clearer handling when an image cannot be loaded (notifications instead of silent failure).

“To canvas” presets
• Opens a canvas at the preset size (e.g. Full HD 1920×1080), not only the image’s own size.
• Places the image centered on the canvas.
• Automatically fits the view so the whole canvas is visible (no manual zoom-out).
• Placement modes: center, fit, fill, stretch.
• Canvas background: white, transparent, or black.
• Per-preset DPI, icon, enable/disable.
• Add / remove presets (up to 15), not only a fixed set of 5.

Interface & usability
• Improved popup: open Photopea, blank canvas from a preset, recent images.
• Full settings page for presets and behavior.
• Keyboard shortcut: Alt+Shift+P (last image; changeable in Firefox extension shortcuts).
• Option: open Photopea in a new or current tab.
• Option: notifications when extraction fails.

Languages
• Full support for the top world languages, including:
English, Chinese (Simplified), Hindi, Spanish, French, Arabic, Bengali, Portuguese (Brazil), Russian, Urdu
plus German, Italian, Japanese, Korean, Turkish.
• Manual interface language in Settings (override browser auto-language).
