I can’t help with the extensions, but I will say Outlook is the hungriest tab on my machine. 850MB on startup with no extensions. So only about half of what you’re seeing, but still way more than anything else I open.

I commend your tab hoarding. I just want to know how much RAM you have to support that. I have 32 GB, Firefox won’t load them until I click on them, and it still struggles at 100 tabs.

I make edible cookie dough all the time. You just need to bake or microwave the flour for a couple minutes until it hits 165. It doesn’t have eggs, but the odds of catching something from them is super low anyway.
