Theme Studio for Reddit — ArclineLabs

Theme Studio changes the appearance of Reddit’s website with selectable colour themes, background scenes and adjustable glass panels.

Use the toolbar menu to choose a look or restore the website’s normal appearance. The background editor lets you choose a bundled scene or use your own picture, adjust scene visibility, and choose light or dark panels. You can assign different scenes to home feed, communities and comment threads.

Focus mode hides the background while keeping the theme colours. Theme changes update open tabs, and a configurable keyboard shortcut toggles focus mode.

Preferences and prepared pictures stay in local extension storage. There are no analytics, advertising trackers, developer servers or separate accounts. The extension does not post, send messages or access account credentials.

For Reddit’s website in Firefox. This independent extension is not affiliated with or endorsed by Reddit or Firefox. Artwork credits are included in the background editor.
