Briefings

A Firefox bug has been open for 24 years where Datasette table pages incorrectly serve an HTTP 'rel=next' link header, causing unnecessary data prefetching and rendering. This feature was first identified in a 2002 blog post by the author, who had previously forgotten about it. The issue affects visitors who click the link, leading to wasted server resources and data retrieval.

Key points

• Firefox has a known bug open for 24 years where Datasette pages incorrectly serve an HTTP 'rel=next' link header, causing unnecessary data prefetching.
• The author had written about this feature in a 2002 blog post but had forgotten about it until recently.

Context

The issue affects users of the Datasette tool, a Python-based data exploration platform. The bug causes unnecessary HTTP requests and server overhead when users click the 'next' link in the network panel.

Limitations

The evidence is limited to a single blog post and a network panel observation. No quantitative impact data or user statistics are provided. The bug's long history (24 years) is noted but no specific resolution date is confirmed.
