+        <p>While writing the previous post about TinyTinyRSS in Pale Moon, I tried to fix an issue I still had with my XSLT: To make HTML tags in &lt;description&gt; blocks work, I had to break an important part of the RSS specification and add tags directly without escaping them. XSLT stylesheets would decode entities or CDATA blocks, and do not provide a function to selectively re-parse XML tags, so I felt I was stuck. I then found out that this bit of code could get me to output the content of a description tag without getting HTML entities, so getting raw HTML as I want it without causing bugs with Pale Moon's RSS preview or bad RSS validator warnings:</p>

+        <p><code>disable-output-escaping</code> <a href="https://www.w3.org/TR/1999/REC-xslt-19991116#disable-output-escaping">is optional</a> according to the W3C specification since version 1. libxslt, Chromium and Internet Explorer do support it, but Firefox <a href="https://developer.mozilla.org/en-US/docs/Web/API/XSLTProcessor/XSL_Transformations_in_Mozilla_FAQ#can_i_do_disable-output-escaping.3f">chose not to</a>, and <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=98168" target="_blank">a Bugzilla ticket</a> for it will celebrate its 20th birthday this year. They do say themselves that this causes issues for RSS support, so I chose to just not care about it. If you are a Firefox user and are seeing raw, unparsed HTML tags in there, I can only suggest using another browser, or just subscribing to this feed and reading this in its home, a RSS aggregator.</p>
