When i click a RSS reader icon on the homepage https://lemmings.world/ then the URL is like https://lemmings.world/feeds/front/......long string here.....xml?sort=Active
and it triggers a download, not display of my Firefox-ESR RSS reader extension (called "Brief"). Other RSS feed like one linked from sub-lemmy https://lemmings.world/c/protonprivacy@lemmy.world is displayed properly.
When I click a Brief icon in address bar of a https://lemmings.world/, then I get correctly subscribed.
When I compare subscribed feed URL with the URL of the on-page button, they are identical.
How this issue can be fixed?
afaik the long string is specific to you (as in, if you have selected subscribed feeds). Please do not share it even if someone asks for it.
for me it worked (i tried in newsraft). can you try some other feed reader, maybe it is "brief" or your personal feed specific issue.
