I can't understand whether I am the only one who have this issue, but it seems to me the Vue.js devtools for FireFox have serious memory leak issue for dozens versions in a row. I've worked on different projects on different PCs and laptops and it is still the same. In earlier version is was easy to notice when you tried to track list of events, but now I just opened them with bran new Vue 3 app with 10 simple components and Firefox memory consumption raised from 1gb to 8gb in 20 seconds which lead Firefox to hang.
