Présentation
Intègre le navigateur avec JDownloader en interrompant le gestionnaire de téléchargement ou via le menu contextuel du clic droit.
This extension connects your browser to the JDownloader, which is a Java-based download manager. The extension offers two operation modes:
1. Sends downloading jobs from the right-click context menu
2. Interrupts the built-in download manager and redirects your requests to the JDownloader
The second mode is disabled by default. To enable it, click on the browser action button once. Whenever the interruption mode is not needed, click the browser action button one more time to disable this optional feature.
Since this extension needs to execute native commands to communicate with the JDownloader, a native client is needed. The instruction to install this NodeJS native client is shown on the first use. Also note that this extension only calls the JDownloader, so you need to have this application on your operating system for this extension to work. You can check the code of the native client on https://github.com/belaviyo/native-client/releases. There is a short video tutorial about the installation of the native client and its usage:

Guideline
- User Experience: Creating a user interface that pleases all users can be a challenging task. Improving the user experience of this extension is largely dependent on feedback from users like you. If you have any comments or suggestions regarding the user interface or other ways to improve the user experience, please fill out this section to help the developer address any issues and make the extension even better.
- Performance: If you have experienced any performance issues with this extension, such as slow browsing or excessive resource usage, we would appreciate it if you could let us know by filling out this section of the feedback form. Reporting these types of issues is crucial, as they can affect the experience of all users. Our technical team will carefully review the extension for any issues and work with the developer to address them as a priority. Thank you for your help in improving the extension for everyone.
- Trust and information access: Unnecessary permissions in an extension's permission list can be off-putting to users and may cause them to uninstall the extension without fully trying it out. At WebExtension.ORG, we regularly monitor hosted extensions to ensure that they do not request any extra permissions, but some mandatory permissions may still appear unnecessary. By providing feedback, you can help the developer determine whether a particular permission is truly necessary or provide a clear explanation for its inclusion. It's important to note that some permission requests in Chrome can be misleading. For example, most extensions require the "storage" permission to save their internal preferences, but the warning message may imply that the extension wants to access your personal information (which is not the case).

Where do Browsers Store Extension Files?
They store installed browser extensions in the user's local profile folder. This is a hidden folder that is not easily accessible to users, as it is intended to store data and settings for the browser and its extensions. The location of a user's local profile folder varies depending on the operating system and the user's account settings. Here are the default locations of the local profile folder on some common operating systems:
- Windows:
C:\Users\<username>\
- Mac: /Users/<username>/
- Linux: /home/<username>/

The "Download with an External Download Manager" extensions enable the redirection of browser downloads to an external download manager, such as Internet Download Manager (IDM). By default, these extensions are disabled and do not interfere with downloads. You must first enable the extension using the action button to redirect downloads. Once enabled, you can proceed with the usual downloading process and observe that the external executable is called instead of the browser's built-in download manager. You can also use the right-click context menu to send your downloads to an external download manager without enabling the interruption mode. For each download manager, there is a separate options page that contains the corresponding command-line arguments.

A test page to evaluate how well your browser is connected to an external download manager. This page contains different downloadable links with different types. For advance use, this page also included a single MP4 video file with no extension to evaluate automatic mime-type detection in case it is not provided by a server.
This page contains a list of sample files to test your browser extension download capabilities of handling different formats. It includes image, audio, video, document, and compressed files. There is a sample file with no file extension and binary mime type to test file extension detection using the "magic bytes" method. In this method, the download manager should detect the correct mime type and file extension based on the binary content that is retrieved from the server. In this method, the file extension that is returned by the server is ignored. Some operating systems such as Linux and Mac OS use the "magic bytes" technique to detect the file extensions, and the provided file extensions in the filename are completely ignored. However, in Windows OS, the operating system relies on the extension that is appended to the filename. There is no "magic bytes" verification.
This page also can be used to see how well a download manager can detect different types. For instance, you can ask your browser's download manager helper extension to collect all the possible download links and extract their file types.
Here is a list of recommended arguments to be passed to some well-known download managers. You can use this section to modify how your browser extension communicates with the external download manager. Also, these arguments can be used in other extensions that use native messaging to send commands to an external application like "External Application Button" by "Andy Portment"
Downloader Command-line Arguments No command-line options. Uses POST requests to "http://127.0.0.1:10029" "[URL]"
Full command-line list: [-fs] [-url=]url1 [-url=]url2 ... where "-fs" can be used to enter to the silent mode. "[URL]" /d "[URL]"
Full command-line list: /d URL [/p local_path] [/f local_file_name] [/q] [/h][/n] [/a] where "/s" argument adds the new job to the scheduler. "/p" sets the path to the location where download saves to the local disk. To set the local filename which overwrites the detection module use "/f" with the suggested filename in front. If you prefer to exit the download manager when file is fetched, use "/q" argument. No command-line options. Uses POST requests to "http://127.0.0.1:9666/flashgot"
For complete list of communication commands take a look at jdownloader.org/knowledge/wiki/terminal /C 'start cmd.exe "/S /K ""%ProgramFiles(x86)%\\GnuWin32\\bin\\wget.exe" --output-document="[FILENAME]" --user-agent="[USERAGENT]" --referer="[REFERRER]" --no-check-certificate --continue --load-cookies=[COOKIES] "[URL]"""'
