YouTube™ Timestamps 제작자: Nhân Trí

NOTE:
• Upon adding this add-on, please immediately go to about:addons and manually tweak the settings for it to start working. This feature is intentional and a reminder that this add-on is experimental.
• Too many timestamps within a period of time (like image no. 1) can show too many comments at once and make it hard to find the exact timestamp you want. I unfortunately can't do anything about it.
• I highly recommend go full screen for comments that have long text (check image no. 2).
• SponsorBlock is supported, though its segments could make it hard to find the timestamps.
• Miniplayer will break this add-on... will fix it somehow (YouTube's SPA is finicky).
• Because this add-on is using YouTube's internal API, there's no rate limit! A few YouTube-related add-ons and userscripts also use it, so it's legal and won't violate YouTube's ToS.
• YouTube doesn't make it easy to just middle click and automatically scrolls down to view Highlighted comment, so open new tab is the best I can do.
• If you want to like/reply a comment, please middle click to open it as a new tab. This add-on is already complex enough (T_T).
• Comments with formatted text (bold, italic, strikethrough) are rendered as normal one. Sincerely sorry!
• If you use custom YouTube theme, comments will still be either white/dark.
• Does not work for shorts and livestreams (while they're live of course, not when they are videos).
• YouTube's custom emojis aren't rendered as images (because YouTube treats Unicode and custom emojis as images) but as text.
• Potentially duplicate comments? Going back to a timestamp too many times or timestamp with too many comments can cause this bug.
• Replies aren't shown because, from my experience, not that many people reply with timestamps.

TODO:
• Add options to remove comments with an x amount of timestamps to root out all certain comments that list out chapters, this moment, etc... which could clog up space and be unnecessary.
• Show other data like display name and options to show/hide them the options menu. Maybe?
• Keyboard shortcuts to navigate between each timestamps and comments within them?
