Using Firefox on a couple of Macs (one of them is >8 years old), and a couple of Linux systems.

Setting aside the fact that it's as fast as or faster than Chrome, it doesn't crawl any of my machines with >500 tabs (this has 562 as of now).

If you want to dig into your performance numbers there's "about:performance" to see what is using your processor and RAM.

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.

Give it a go.

Umm yes I did that and nothing seemed to be doing anything excessive

Tried going back to Firefox... seems to be running ok at the moment which I'm well happy with... no idea what was causing my problems before
