Does constant context-switching in the browser hurt your focus?

I’m building BubbleBrowser to help reduce mental clutter and context switching while browsing, but before going deeper, I’d love to understand how real people experience this problem.

Do you feel distracted by too many tabs, jumping between tasks, or losing your train of thought while working in the browser?

Curious to hear what actually breaks your focus today — and what you’ve tried (or given up on).
