Using STP Release 102 for usual browsing. Set as default About 15 tabs open Over 1/2 open pages are github.com + a few others (gmail, corporate mail [verse], octobox etc) No noticeable CPU from STP Can switch tabs ok When clicking on a tab any interaction ie with a link will result in the progress bar (in the input box) going perhaps 15% - no further Seems same for all tabs Apple Feedback ID: FB7621482 OS: MacOS 10.15.4 19E250c
