I have a set of extensions that are core to the way I use Waterfox, namely: When sitting there doing nothing I can look in the Windows task manager and see Waterfox using 10-30% CPU. The new Waterfox is slower with 900 tabs than the old one was with 1300. After noticing the slowness I tried using Auto Unload Tab instead, but it seemed to make no difference. I regularly have more than 1000 tabs open and this has always been workable with older versions of Waterfox (and Firefox) due to a combination of extensions, in particular BarTab Plus, which will unload unused tabs. I've tried disabling various extensions but nothing seemed to help. Even when moving the mouse over a button, link, or a chrome widget like a menu, there can be a delay before the cursor changes.

There will be noticeable stutter and delay when typing, clicking, etc.

It seems okay when first started up, but the longer it is open the slower it gets. I was on version 55 until the past couple months, when I upgraded to the 2020 version (classic). I've been using Waterfox since the Firefox XUL fiasco.
