4.0.6 hotfix: fixes the technology list showing many narrow columns with a horizontal scrollbar on Firefox. The list now displays as intended in two columns with vertical scrolling only. (Includes all 4.0.5 changes: two-column layout, Bulk lookup shortcut, faster icons, dark mode fixes.)

What's new in 4.0.5:
- New two-column results layout: see more technologies at a glance with far less scrolling
- New "Bulk lookup" shortcut to check a whole list of websites on Ful.io
- Faster icon loading from our new CDN
- Page title now only truncates when it actually overflows
- Fixed a thin white border around the popup, most visible in dark mode
