Wallpapers, frosted.

Any image as your Facebook background. The surface-transparency slider decides how much shows through — from barely-there to fully readable.

Everything Facebook won't let you change

Facebook ships one blue look. FB Customizer gives the control back — and keeps it working as Facebook changes.

Themed everywhere, not just the feed

Facebook paints dialogs, comments, menus and tooltips with hardcoded styles that break most themes. FB Customizer's five-layer engine re-emits the full variable stack inside them, so every surface follows your palette.

Your palette, down to the border

Accent, background, card, text, muted and border colors, the typeface and its size — all yours, applied live.

Presets & sync

Save setups like “Night reading”, export them, and sync across your computers.

Zero network. Ever.

No servers, no accounts, no analytics. Pages are processed locally and your settings stay in your browser's sync storage. It only changes what you see — never what's in your feed.

Questions

Is it safe for my account?

Yes. FB Customizer only changes how pages look in your browser. It processes pages locally on your device and never stores or transmits your Facebook content anywhere — it has no servers, no accounts, and no analytics. Your settings stay in your browser. See the privacy policy for details.

How do I install it?

Straight from the Chrome Web Store — click “Add to Chrome”, confirm, and your Facebook tabs are themed immediately. No unzipping, no developer mode.

Why do I need an extension for this?

Facebook offers no theme, color or font settings of its own. An extension is the only way to restyle its pages — and FB Customizer changes only how they look, never what's in them.

Will it keep working?

Facebook changes its pages regularly, so themes can occasionally need small fixes. We test supported desktop Facebook surfaces and publish updates as they are available.

One click. Your Facebook.
