In case my other answer gets lost in the dumps: Open Mull --> Bookmarks --> Select all of your bookmarks ---> Share ---> "Copy to clipboard" --> Create spreadsheet using something like excel or collabora on android ---> Paste in spreadsheet and save ---> Move file to computer and open file in calc or excel --> Highlight links and "Ignore all" in spellcheck, links should now be hyperlinks ---> Export as HTML ---> open new browser and navigate to bookmark manager --> "import from HTML" --> Done
Woah keep forgetting people can still see my reply even after deleting it. I didn't want to spam OP since I basically copied my other reply that's why I deleted
I don't think there is a way to export a file as usual.
What I did was create a Firefox account using a fake/alias email through SimpleLogin just to backup the bookmarks. If you don't have any privacy concerns then just using your usual email to create the account and logging in to Mull/Firefox that way should do the trick. Granted, I don't really know how well that worked since I haven't logged in to restore them, because I didn't intend to, just wanted to save them. But I think that's the only way on Mull. I hope someone else knows a way though.
