• Low-Bitrate MP4 (for listening) — Download the smallest video variant for background audio (saved as .mp4 — honest naming; Rumble doesn't expose a pure audio track).

Driven by the RX_CSS_TOGGLES registry — each toggle is a proper feature module with its own setting key, hot-reload support, and options-page card:

Click the extension icon → gear button to open the dedicated options page. Modelled on Astra-Deck's settings workspace:

• App bar with version + live storage status
• Workspace hero + Open Settings Editor CTA
• 5-card stats overview (Enabled features, Storage size, Channels, Keywords, Chatters)
• Full-parity Export / Import — backups now include both rx_settings AND per-origin localStorage (watch progress, watch/search history, bookmarks, volume memory, rant archives). Export format: exportVersion: 2; v1 imports still work. Imports are allowlisted by key so a crafted file cannot smuggle arbitrary localStorage keys onto rumble.com.
• Reset All Data broadcasts clearLocalData to every open Rumble tab and reports the honest "Cleared N per-site keys across M tabs" count
• Settings editor modal with dirty-draft workflow: search, sidebar group nav (9 groups), chips for unsaved / needs-attention, Restore Defaults / Discard / Save toolbar, per-field Reset buttons
• Per-control editors infer from value type: toggle / number / text / textarea / list / JSON / enum-dropdown (theme & siteTheme)
• Focus trap, beforeunload guard on unsaved draft, live re-sync via chrome.storage.onChanged

Press Ctrl+Shift+X on any Rumble page (or shift-click the popup gear) to open the original in-page settings modal with:

• 7 categorized sidebar tabs with color-coded icons
• Theme picker with live preview dots
• Playback speed slider
• Homepage category visibility toggles
• Blocked channels / keywords / chatters chip lists
• Hot-reload: most features re-init without a page reload

Click the extension icon for quick toggles, grouped by category with enabled-count badges:

• 7 collapsible category groups
• Debounced writes (120 ms) with pagehide flush — rapid toggles coalesce into one write
• Settings gear — Opens the options page (shift-click for in-page modal)
• GitHub link — Direct link to this repository
• Update checker — Checks GitHub Releases for new versions

1. Grab RumbleX-chrome.zip from Releases
2. Extract the zip
3. Visit chrome://extensions and enable Developer mode
4. Click Load unpacked and select the extracted folder

Or drag RumbleX-v1.9.3.crx directly onto chrome://extensions (Developer mode on).

1. Download RumbleX-firefox.zip from Releases
2. Go to about:debugging#/runtime/this-firefox
3. Click Load Temporary Add-on and select manifest.json inside the extracted folder

Install RumbleX.user.js directly — note: the userscript version lags behind the extension on download features (no Web Worker / mux.js bundle).

• Vanilla JavaScript — no frameworks, no build step
• Chrome Extension Manifest V3 + Firefox Manifest V2 (parallel manifests)
• chrome.storage.local for settings persistence
• localStorage (per-origin) for watch progress, volume memory, history, rant archives
• mux.js (bundled) for HLS segment transmuxing in a Web Worker
• AbortController + generation-counter guards for cancellable async work
• Anti-FOUC: CSS injected at document_start
• GitHub Releases API for update checking
• Download host allowlist (rumble.com, 1a-1791.com, rumble.cloud) enforced in the background worker

• All download URLs are validated against a host allowlist before hitting chrome.downloads.
• LiveChatEnhance uses a TreeWalker on Text nodes only — Rumble's chat markup is never re-parsed through innerHTML.
• Download UI is built via DOM APIs; no network-influenced text (error messages, response bodies, CDN probe results) ever reaches the HTML parser.
• Backup imports are allowlisted: setLocalData rejects any key outside the RX_LOCAL_STORAGE_KEYS list + rx_rants_ prefix, so a crafted file cannot write arbitrary keys to rumble.com's origin.

cd extension
./build.sh       # produces RumbleX-chrome.zip and RumbleX-firefox.zip in the parent dir

Requires zip (Git Bash on Windows: use PowerShell Compress-Archive fallback). See CHANGELOG.md for per-version details.
