Working on updating dat-webext to use the latest libdweb changes. This should get networking working again on Firefox 67+
Looks to be working now, and I'll try a push out a release to Cliqz beta channel tomorrow.
I also managed to get a crazy CI setup running to test dat swarming and the DatArchive API in a headless firefox browser, which should help to keep track of regressions in future!
