The + sign in top indicates that the string is longer, if you can resize the terminal window top can display longer process names.

My guess is, that these processes belong to firefox (sometimes I observe "Isolated Web Content"), a feature introduced in May (see
https://blog.mozilla.org/security/2021/05/18/introducing-site-isolation-in-firefox/). You can check with ps -ef (which gives you parent process ids)...
