I was using foxfilter extension on spin browser in android and spin uses Firefox at it's core . The extension used to work well until some point in the past and suddenly it stopped working . I reached out to foxfilter support and they told Firefox stopped supporting some extensions on Android and thus the issue . Is there anyway you could start supporting foxfilter on firefox Android or can i use an olderversion of firefox on Android to get foxfilter working . If so could you guide me how to get that version installed ?
