Webkit 2.4.x (the last release with webkit1 api support) is deprecated, unmaintained for almsot 3 years, does not support gtk3, and has not even received security fixes for quite some time. Any chance to switch to webkit versions based on the current webkit2 api?
newer versions of webkit api do not support GTK 2, only GTK 3. Claws Mail is GTK 2. bug #2371 is RFE for 'port to gtk 3', when that happens the fancy plugin will have to be updated, so this separate RFE doesn't make sense. Therefore I'm closing it as a duplicate. *** This bug has been marked as a duplicate of bug 2371 ***
This is not just a RFE. It is a security problem: As far as I know, up to now close to 200 security fixes have been committed to the webkit2 versions which have not been applied to 2.4.x (i.e. webkit1). And there is a definite statement of the webkit development team that there will be no security backports to old webkit versions. See e.g. https://blogs.gnome.org/mcatanzaro/2016/02/01/on-webkit-security-updates/ The linux distribution I use is already discussing if and when webkit 2.4.x should be dropped for security reasons. If claws really wants long-term gtk2 support, I think it would have to switch from webkit to cef for html mail support.
(In reply to comment #2) That is now a different issue. Re-closing. *** This bug has been marked as a duplicate of bug 2371 ***
