YouTube Timestamps Firefox

YouTube Timestamps

By: ris58h
Shows timestamps from YouTube comments on timeline.

Features & Capabilities

YouTube Timestamps is a handy Chrome extension that enriches your YouTube watching experience by displaying timestamps extracted from video comments directly on the video timeline. This feature allows users to quickly jump to moments referenced by other viewers without needing to search through comments manually. Hovering over these timestamps previews the corresponding comment for context.

The extension supports fullscreen and theater modes, works seamlessly with embedded videos, and includes a dark theme for comfortable viewing. It's open-source, offering transparency and community-driven improvements. Note that timestamps are derived from the first 100 comments only, and long comment previews can be scrolled by scrolling on the hovered timestamp itself.

User Reviews

The YouTube Timestamps add-on is generally useful and improves viewing by surfacing timestamped comments, with strong positive sentiment. However, SponsorBlock conflicts and intermittent display/interaction issues are the main concerns. Common requests include auto pop-ups during playback, navigation hotkeys, comment search, easier ways to jump to or interact with a comment, and larger clickable targets for the timestamps.
Pros
  • Generally reliable and works well most of the time.
  • Enhances the viewing experience by surfacing timestamped comments during playback.
  • Well-received and considered useful, especially for gaming/video content.
Cons
  • Incompatibility with SponsorBlock.
  • Some timestamp comments are not shown consistently and hover can stop working.
  • Timestamps area is too small to click reliably.
  • Lacks direct navigation/interactivity from the popup to the comment (e.g., jump to comment or interact).
  • Does not work with bulk timestamp comments.

Is YouTube Timestamps Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

YouTube Timestamps requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood measures the probability that a Firefox add-on may turn malicious.
