How to: firefox wsod
firefox 87 can crash during uploads  -- the entire browser goes, including all other browser tabs, everything turns white

however you can hit `F12` in the up2k tab and use the devtools to see how far you got in the uploads:

* get a complete list of all uploads, organized by status (ok / no-good / busy / queued):  
  `var tabs = { ok:[], ng:[], bz:[], q:[] }; for (var a of up2k.ui.tab) tabs[a.in].push(a); tabs`

* list of filenames which failed:  
  `​var ng = []; for (var a of up2k.ui.tab) if (a.in != 'ok') ng.push(a.hn.split('
')[0]); ng`

* send the list of filenames to copyparty for safekeeping:  
  `await fetch('/inc', {method:'PUT', body:JSON.stringify(ng,null,1)})`
