Safari very slow since Gmail upgraded to the new version
I always keep two different browsers open (in this case Safari and Chrome, both of which I also have on the iPhone), so that I can keep my work (G-suite) email and my personal email open at the same time.
Since Google released the "new" Gmail interface, Safari has been unable to handle it. From time to time it shows a tab with the message "Web page is using significant energy. Closing it may improve the responsiveness of your Mac" - and it really does! - or just stops updating. Sometimes refreshing the tab altogether works (although it loads veeeery slowly), sometimes the only solution is to shut down Safari and start a new session.
I thought OS X Mojave would solve the problem, but it still persists. I am using a 2013 Macbook Air with the newest 12.0 version of Safari.
I have tried to clear the cache, cookies, extensions, everything, but the problem is still there. An Etrecheck found Adware in my computer, which it seems I've successfully got ridden of. The problem is not as severe now, but still persists. I am pasting the Etrecheck report below to give a better overview of my current situation:
Any suggestions? Tks!
