Description Nigel Jones 2020-03-10 09:52:56 PDT

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
