Frequently asked
questions.
Read the full FAQ Which browsers does it support?
Fog Mode is currently built for desktop Chrome, version 120 and later. These examples work on a phone-sized page, but they aren’t a mobile extension.
Browser details ↗Will it declutter any website?
No. Clean article view opens the main article on a page. It doesn’t remove ads, sidebars or recommendations from every site. Fog Mode’s other tools change text size and spacing, add the red reading guide and reduce page animations. Fog Mode can’t run on browser settings pages or the Chrome Web Store. Some tools can’t change PDFs, pages shown inside other pages, or apps that draw text instead of using webpage text.
Does closing Fog Mode stop everything?
No. Closing the controls lets you browse with the tools still running. Stop all ends active effects, scrolling, sound and sessions, switches off reminders and the reading settings that apply automatically, and hides attached notes. Saved notes and preferences remain.
Can I install it now?
Not yet. The Install page will show the Chrome Web Store link once Google approves Fog Mode. The current tools will be free.
Try decluttering
and the red guide.
