how do you switch on queue mode

non-modern appearance and Checksum not work

Abandoned from 2019 and it doesn't really provide something really useful.

Recently migrated from Chrome so this plugin seemed like a perfect solution to get Chrome-like download management, but after a few days I noticed Firefox' WebExtensions process was eating 7.5gb memory! Disabled this plugin and it's dropped to just 43mb. Clearly a memory leak in the code somewhere unfortunately.

good
