Bookmarks Checker

Identify dead links in Firefox and Chrome bookmarks.

Background

So many browser bookmarks – there are 1,900 URLs in my bookmarks. And in just one year, 120 of those URLs ceased to exist.

A simple PHP prototype script provided a slow way (~1 URL per second) of checking for dead links.

I switched to Python to leverage its threading capabilities and speed up the process. Then I finally got round to adding cURL multi to the PHP script.

Example

$ php bookmarks_checker.php

1883 links being checked ...

error | https://www.nxytimes.com/ | 0 | 4.999007 | nxytimes
<...>

See generated logfile bookmarks_checker.log
URL parse time: 177.642 s

95 links failed
1788 links verified

Scripts

  • Python 3
  • Python 2
  • PHP and cURL

Usage

Export browser bookmarks.

The scripts by default will attempt to load a file in the same directory called bookmarks.html An alternative filename can be specified on the command-line.

The scripts parse the file and try to access each URL, printing a list of URLs that cannot be accessed (which will intermittently include a false positive).

Python

    python3 bookmarks_checker.py

    python bookmarks_checker_py2.py

(or make the file executable and run directly e.g. ./bookmarks_checker.py)

Switches

-h or --help displays help text.

-f <file> allows an alternatively-named file to be loaded instead of the default bookmarks.html

PHP

    php bookmarks_checker.php [file]

Exporting Browser Bookmarks <a id="export"></a>

Firefox

Bookmarks > Show All Bookmarks > Import and Backup > Export Bookmarks to HTML

Chrome

Access Chrome's Bookmark Manager with:

<kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>O</kbd>

or

chrome://bookmarks/

then click Organize > Export bookmarks to HTML file ...

Other

Python Scripts

Setting DEBUG = True will show all URLs as access is attempted, and either the successful response or the failure error message.
