<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 style="white-space: nowrap;">(<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 your browser. <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 or results take longer than 15 seconds, you can close the tab and launch this page 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>
