<h1>Firefox Bookmark Backup Reader/Decompressor</h1>
</header>
<article>
<div id="main">
<p><em>Firefox creates frequent backups of your bookmarks. Automatic backups are compressed using Mozilla's flavor of LZ4 compression (.jsonlz4 file extension), while backups you create yourself (in the Library window) are not compressed (.json file extension by default). This tool can convert a backup file to the HTML export format.</em></p>
<h2>Step 1: Load File</h2>
<p>Drag and drop one .jsonlz4 (or .json) bookmark backup file onto the empty text box, or use the Browse... button on the right. <span>(<button onclick="document.getElementById('backhelp').style.display=''; this.parentNode.style.display='none';">HELP</button>)</span><span id="backhelp" style="display:none; background-color:#ffc;">These files are stored in the <strong>bookmarkbackups</strong> folder in your Firefox profile folder. If you are unfamiliar with how to locate your profile folder, please see: <a href="https://support.mozilla.org/kb/profiles-where-firefox-stores-user-data" target="_blank">Profiles - Where Firefox stores your bookmarks, passwords and other user data</a> on Mozilla Support.</span> This file is not sent to the network, it is only read within this page in Firefox. <strong><em>Performance Note:</em></strong> Decompressing files and working with large sets of bookmarks is processor intensive, so please be patient. If the fan won't stop running, you can close the tab and launch the document again.</p>
<div id="uploaddiv">
<textarea id="drop_zone" ondrop="drop_handler(event);" ondragover="dragover_handler(event);" ondragend="dragend_handler(event);" style="width:80%" autocomplete="false" placeholder="Drop file here"></textarea>
<div style="position:absolute; right:0; top:0; width:calc(20% - 18px); cursor: pointer;" onclick="document.querySelector('#btnBrowse').click();";>
<p style="margin-top:2em; text-align:center;">Or open using: <br><br><input type="file" id="btnBrowse" onchange="loadFile(this);" style="width: 80px"></p>
</div>
</div>
<p><em>Note: To try a different file, reload this page (Windows: Ctrl+r. Mac: Command+r). Or click the reload button in the address bar.</em></p>
<h2>Step 2: Convert / Repair / Save Your Bookmarks</h2>
