Fix: убрать blob: из CSP для Chrome - #26
Merged

Conversation
Chrome Manifest V3 prohibits 'blob:' in script-src CSP directive for extension pages, causing the extension to fail loading with: "Insecure CSP value blob: in directive script-src" Removed blob: from content_security_policy.extension_pages in manifest.chrome.json. User plugins now load via sandbox iframe fallback instead of blob URL. Firefox manifest is unchanged. 🤖 Generated with Codebuff Co-Authored-By: Codebuff <noreply@codebuff.com>

Благодарю за интерес к проекту и столь подробный PR!
Разработка ведётся в первую очередь под firefox, поведение в chromium тестируется только на финальных стадиях. Спасибо, что нашли и решили такую критичную проблему!

Проблема
При загрузке расширения в Chrome/Chromium расширение не загружается:
Chrome в Manifest V3 запрещает
blob:вscript-srcCSP для страниц расширения.Причина
В
manifest.chrome.jsonCSP содержитblob::Это используется
PluginManager._injectFromBlob()для динамического импорта плагинов через blob URL.Решение
Убран
blob:из CSP только для Chrome. Вmanifest.firefox.jsonblob:оставлен — Firefox его поддерживает.Влияние на функциональность
В
PluginManager._loadViaSW()есть цепочка фолбэков:chrome.scripting.executeScript()— приоритетный метод_injectScript()— загрузка изplugin-runtime/{key}.js_injectFromBlob()— blob URL (пропускается в Chrome)_createSandbox()— sandbox iframeПри удалении
blob:Chrome использует sandbox-iframe для загрузки плагинов — это работает корректно.Тесты
