@Gargron I cannot really compare as I use Vivaldi as my primary browser with lots of tabs left open.
I use LibreWolf differently normally in private browsing mode for searches, route planning or reading the news.
Especially where a website makes you choose between accepting tracking or logging in.
I have other browsers installed for single uses - Chromium for Wire IM and nothing else.
I have noticed that the Helium browser (not using Helium services) feels much faster than Chromium.
