Facebook URL fix

This is a Google Chrome extension which shortens Facebook URLs to reduce tracking and unresponsive situations.

Author: LQ2' (Website | GitHub)

Based on Query stripper by Rudie Dirkx.

Thanks Custom Icon Design for the wrench icon used in the icon of this extension.

Note

A new extension focusing on fixing Facebook URLs (like this) is being written, with a completely different mechanism. New updates to Facebook URL fix will not change the main mechanism derived from Query stripper.

Features

• Removes unnecessary query parameters from Facebook URLs
• Shortens album ID containing a.<something> in query parameter set in legacy album links
• Enters external links directly. (Facebook's reference tracking is skipped.)
• Directly enters a single post in a group from a notification about the post.

Removed feature

• Changes modern photo links into legacy links

To do

• [Major feature] Actively shorten and remove unnecessary things in <a> tags in the page. This feature will be implemented in the new extension!
• [Bugfix] Tab content is not updated when external links are in fact inside Facebook network (e.g. *.facebook.com).

Installation

1. Download the ZIP file of the latest release of this extension.
2. Extract the file into a folder.
3. Open Chrome and turn on its Developer mode.
4. Click Load unpacked extension and select the folder containing this extension.

How does this extension work?

1. Removing unnecessary query parameters from Facebook URLs

For example, this URL points to a page that shows a reply to a comment on a post:

https://www.facebook.com/<somebody>/posts/<post_id>?ref=notif&notif_t=like&notif_id=<notif_id>&comment_id=<comment_id>&reply_comment_id=<reply_comment_id>

Unneeded query parameters: ref, notif_t, notif_id

New URL:

https://www.facebook.com/<somebody>/posts/<post_id>?comment_id=<comment_id>&reply_comment_id=<reply_comment_id>

2. Shortening album ID containing a.<something> in query parameter set in legacy album links

(Available since version 1.1)

Here is a legacy link to a photo album:

https://www.facebook.com/media/set/?set=a.<minimal_numeric_part>.<extra_numeric_part_1>.<extra_numeric_part_2>

This will be changed into:

https://www.facebook.com/media/set/?set=a.<minimal_numeric_part>

3. Entering external links directly

(Available since version 1.2)

Here is a redirection link to an external site:

http://l.facebook.com/l.php?u=http%3A%2F%2Fexample.com%2F&h=<some code>

The external link is extracted and entered.

http://example.com/

4. Directly entering a single post in a group from a notification about the post

(Available since version 1.5)

A link to the post points to a page containing not only the post, but also other posts in the same group.

https://www.facebook.com/groups/<group_name_or_id>/?multi_permalinks=<single_post_id>

The page can cause additional, unnecessary load. A Facebook user has already got a choice to view all posts in the group by clicking Discussion.

The following link is much straighter.

https://www.facebook.com/groups/<group_name_or_id>/permalink/<single_post_id>

Notes:

• The user will not see pinned post in the group until he/she clicks Discussion.
• Notifications about multiple posts in a group are safely bypassed by this feature.
