SaifLoad Video Downloader v3.9.28 — Firefox package

Base package: SaifLoad_Chrome_v3.9.28_MobileOverlayFix.zip
Engine files are retained from the supplied base package. This package is not a new feature build.

Browser family: Firefox
Target browser: Firefox

Install:
- Desktop Chromium browsers: extract this ZIP, open the browser's extensions page, enable Developer Mode, choose Load unpacked, and select the extracted folder containing manifest.json.
- For official store distribution, package and submit through the relevant browser's official extension store.

IMPORTANT — Firefox compatibility candidate, NOT production-certified.
The manifest was adapted to Firefox's MV3 background-script format and Chromium-only side_panel/offscreen manifest entries were removed. The extension source still uses Chromium-specific APIs including chrome.offscreen, chrome.sidePanel, declarativeNetRequest, and action behavior. Some features may fail or be unavailable in Firefox until source-level compatibility work and live runtime testing are completed. Do not publish as a fully supported stable Firefox release yet.
