Does anyone else feel like Firefox is running kind of sluggish recently? I'm using Zen browser on Zorin OS. I feel loading times for everything has increased in the last couple of weeks. Element like volume sliders and such aren't responsive for like 5-10 seconds.

Not sure if it's my system or not but other apps run fine. I've already done optimizations in about:config but I havent tried switching browser, because I don't want to, I like Zen browser.
