I have to disagree with Firefox... in terms of functionality and configurability it's by far and away my preferred browser but in terms of performance it just crunches to a crawl on my Mac. Load times of pages are absolutely fine but changing tabs crunch , scroll down the webpage judderfreeze whereas Edge is just silky smooth.
Maybe it's an extension or three I'm running but I just want to use the bloody thing not sit there and figure out what extension is not working nicely (and then potentially find out it's none of them) on one platform but is fine on another.
Every so often I go back and have look to see if it's improvised but it hasn't in the last few years for me.
Did that and weirdly nothing seems to be excessive... indeed the Macs own performance monitor doesn't suggest anything is particular excessively using cpu or ram but here it is juddering away especially when scrolling pages.
Three year old Mac btw... everything else runs pretty well... if I get a chance I might fire up Firefox in Parallels and see if it's a Mac issue
When you write "about:performance" to your address bar, and press enter, you should access to the internal performance monitoring page of Firefox. That should list every tab and extension by RAM use and power impact.
I use brave, arc, firefox, chrome, and safari. Safari is the best performing. 'tis a shame that other web browsers are unable to use it as their rendering engine.
