Converter from content MathML to presentation MathML
This add-on is not compatible with your version of SeaMonkey because of the following:

Each time a nsDOMContentLoaded event is raised on a tab, a function is executed to convert from content to presentation MathML. This latter flavor can then be rendered natively by Gecko.
If no <math> elements are present on the page, the conversion function will return immediately. Otherwise, an instance of nsIXSLTProcessor initilialized with David's ctop.xsl stylesheet is used to perform the conversion from content to presentation MathML. Note that the stylesheet is not applied to the whole HTML document but to each <math> element individually.
Be aware about these listeners and function calls on each page if performance is important for your browsing experience. The add-on uses only one single nsIXSLTProcessor object, initialized the first time it is necessary and kept during all the life time of the add-on. This is to avoid to create and destroy the object (which requires loading the XSLT stylesheet in a DOM tree) each time a conversion is necessary.
