I have Firefox containers and Simple Tab Groups extension installed, which keeps my tabs in the browser, but automatically suspends them when they are not visible. This was my sweet spot for tabs, because I do not have to bookmark them permanently, and I can instantly switch to my "workspace" anytime. I experience the opposite of you with Chrome struggling with several tabs. At around 30 tabs, Chrome absolutely throttles my moderately powerful 8 core 16 thread CPU laptop with 24GB RAM, while Firefox has no issues with it. Firefox doesn't even sweat even if I have those tabs open with Spotify and Gmail, one that presumably uses hardware DRM decryption, and the other websockets for email and chat, plus whatever tracking Google wants to do.
