Features & Capabilities

The add-on modifies the YouTube live-chat for both live-streams and replay, allowing to either highlight, show as subtitles, or delete chat-messages matching a set of preset and customizable filter rules. This is useful e.g. for showing Hololive live-chat translator messages as subtitles, highlighting English comments, or deleting annoying messages and emoji.

Main features of the add-on:

Highlighting of YouTube live-chat messages via a separated chat-box
View live-chat messages as subtitles for YouTube player
Delete YouTube live-chat messages
Customizable filter rules, allowing to either enter simple search-texts, or to use more complex options (e.g. Regular Expressions)
Customizable subtitles style
Settings are applied to all open YouTube pages and live-chats immediatly
Light- and Dark-theme support
Visual design close to YouTube's live-chat and video player design, aiming to not change the look of the YouTube website

Experimental:

Filter messages regarding characters of languages. E.g. show only YouTube Live-chat messages written with Latin (English) characters.

If there are features or improvements you'd like to suggest, please go to the Support website linked on this Add-On page. I would really appreciate your feedback and ideas for improving this add-on together ^_^.

Is Filter for YouTube™ live-chats 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.

Filter for YouTube™ live-chats requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Filter for YouTube™ live-chats may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
