what is android-titanium-extension fr?

This is a browser extension built for Titanium Browser for Android, a Chromium based mobile browser, though it can also work with other Chromium based browsers that support extensions. It adds features that Chromium on Android does not offer out of the box. One main feature is installing browser extensions from marketplaces other than the Chrome Web Store. Titanium Browser can already get extensions from the Chrome Web Store by enabling desktop site mode, but this extension adds support for Opera Add-ons and Microsoft Edge Add-ons as well. A user can either use a built in download flow for those marketplaces, or manually copy an extension's marketplace page URL into the extension's options screen to fetch and install it. A second main feature is forwarding browser downloads to an external download manager app instead of using the browser's own download handling. This requires configuring which download manager to use in the extension's options, either by picking a preset for a known app or by manually entering that app's package ID and the intent format it expects. Once set up, downloads can be automatically redirected to the chosen download manager, or a user can long press a link and choose an option from the context menu to send that specific link to the download manager manually. Installing the extension itself means downloading a packed zip file from the project's Releases page, extracting it, then using the browser's Developer mode and Load unpacked option to add it. The README notes that using the alternative marketplace installer on browsers other than Titanium requires a patched version of a specific Chromium source file, so full functionality outside Titanium Browser is not guaranteed. The project is released under the GPLv2 license.
