Why is firefox running in background even when uninstalled?

cn flag

I have uninstalled firefox and also removed .mozilla dir from home dir. These processes come up instantly even after they are killed. How to determine what is creating these processes? They keep using CPU upto 40-50% when viewed in htop.

What release of Ubuntu is this? And how exactly did you uninstall Firefox? Also please add to your question the complete output of `snap list firefox` and of `apt list firefox`

Programs that are already running aren't stopped by an uninstall, or by removal of the binary. A running program has all it needs in its process. Use `pkill -9 firefox`.

@Esther I don't recognize puppeteer, other things running (suspecting them) are qBittorrent web UI, trilium notes (node js), pi-hole. Also, there's no file `/usr/bin/firefox` or `/usr/lib/firefox/firefox`

Didn't actually figure out how to know who created the process or ran the /usr/bin/firefox command. But a docker container was running, so tried stopping and deleting it, and it worked.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
