Collapsing the Vivaldi Tab Sidebar

tl;dr: In Vivaldi, middle clicking the separator between the tab sidebar and the web page will either collapse or expand the sidebar; when collapsed, it shows just the tab favicons, and the workspace selector icon.

If you want to know how I got to that point, read on.

Diagnosing Vivaldi resource usage

I recently noticed my CPU usage was high, and it was due to my open Vivaldi browser. I wasn't sure what tab was causing the issue, so I searched to see if Vivaldi had any tools for reporting this.

It turns out that Shift-Esc will open a task manager, and you can sort on any of:

  • Task (a string representing high level things like the browser as a whole, GPU process, worker tabs, and more)
  • Memory footprint
  • CPU (this was what I was interested in!)
  • Network usage
  • Process ID

You can select any task to end its process.

I was able to quickly track down the issue to a background worker running for a PWA window I'd closed earlier, and ended the process.

Search tips

  • Use #{some tag} or tag:{some tag} to filter by tag; using this more than once will find results that match all tags.
  • Use year:{year} to filter by year. If you use this multiple times, the last one wins.
  • Use begin:{year-month-day} to restrict to results beginning on that day. Last one wins.
  • Use end:{year-month-day} to restrict to results ending on that day. Last one wins.
