Floccus add-on compatibility

[Virgus]

Dear all, this is not a bug related issue, just a compatibility issue concerning Floccus add-on. When I discovered Waterfox-Classic I was able to use floccus without any issue, but with the recent updates (latest WFclassic and any version of Floccus) the message I get is that "Floccus bookmarks sync is incompatible with Waterfox 56.6".

Is there a way to tweak the xpi file to make it compatible again as we used to do with legacy extensions ? Or it would be just a waste of time to try using it on the classic version ?

Thanks, V.
