The worst is when someone is sharing their screen in zoom and then complaining about the lag in Chrome, while you can see the 80+ tabs… I even mentioned it to someone once but did she close them? No. Of course not.
Honestly ... I think that's a myth. I have 200+ FF Nightly tabs open, and I did have up to five tab groups with 100+ tabs each, as well as dozens of Addons, including the notoriously laggy Dark Reader, and I don't notice any slowdown I wouldn't call acceptable - just the usual suspects (Teams and google apps) are crap, but that's just incompatibility with standards on their part. And I don't have any crazy PC or something, just a pretty old 5 2600 and for the most part 16 GB Ram (which did get pretty tight with Minecraft, Idea and FF running), now 32 GB Detotaded Wam.
I didn't realize Dark Reader was laggy or known to be laggy but it makes sense. It doesn't matter in any case, you'd have to pry it from my cold dead eyes
Well it does alter the whole website, in consideration of other parts of the website, which means it fully parses it. Therefore a website is basically handled two or three times before it's finally displayed.
It's a right click and delete. I keep a folder called tmp for exactly this reason. I really don't understand why people do it but man it is infuriating watching someone do it. Maybe it's a bit of ocd tendencies but I absolutely hate it.
