Delete everything and start over?

i just started playing around and importing bookmarks from pinboard and diigo. i’ve had to manually edit the bookmark files to split them into smaller files for import. i’ve got everything sorted with my tests but i’d like to wipe everything out and restart so i don’t get a bunch of duplicates.

is that possible? thank you.

So sorry for this late reply. Yeah you just need to uninstall the extension, however, if you re-import things they will just be overwritten, so no duplicates will be generated.
