Fix YouTube Comments Showing Black Text in Dark Mode [2025 Guide]

YouTube comments are a great way to engage with creators and viewers. But some users face a strange bug when using dark mode on the YouTube website or app—typed comments appear in black text, making it hard to see what you’re writing. This issue mainly affects PC users, especially on browsers like Chrome and Firefox. This guide will explain why this happens and walk you through practical ways to fix it.

Why Do YouTube Comments Appear in Black Font?

This issue usually appears when typing a comment—not after posting it. Once the comment is published, the text appears in white, as expected. Most users facing this problem are on desktop browsers using dark mode. Chrome users are the most affected, but others on Firefox, Brave, and Edge have reported the same.

The problem could be caused by:

• YouTube UI bugs after recent updates

• Conflicts with browser color settings

• App glitches on mobile devices

• Extensions or theme settings interfering with comment input fields

If you’re facing this issue, try the solutions below depending on your device and browser.

Fixes for YouTube Comment Black Text in Dark Mode

1. Switch to Another Google Account

Some users fixed the issue by switching to a different Google account. Here’s how:

• Go to YouTube and click your profile icon

• Select Switch Account > Add Account

• Sign in with another Gmail ID

2. Type Comment as Reply

Another workaround is to type your comment as a reply to an existing comment. The text in the reply box usually appears in white even if the main comment box shows black text.

Here’s what to do:

• Find an existing comment on the video

• Click Reply and type your message

• Copy the reply text

• Paste it into the main comment box and press Comment

This lets you bypass the typing bug while still posting your message in the right place.

3. Change Color Settings in the Firefox Browser

If you’re using Firefox and facing this issue, try adjusting the browser’s color settings:

• Open Firefox and go to about:preferences

• Scroll to Language and Appearance > Colors

• Change Text color to white

• Uncheck Use system colors

• Click OK to save

Now revisit YouTube and check if the comment text appears in white during typing.

4. Add a Custom Filter on uBlock Origin

If you use uBlock Origin, adding a custom filter can solve the problem. Note: This method won’t work on Chrome due to its extension limitations.

Steps:

• Open Firefox (or other supported browser)

• Go to about:addons and click Options for uBlock Origin

• Open the My Filters tab

• Paste this line:
  youtube.com##div.style-scope.yt-formatted-string:style(color:white!important;)

• Click Apply Changes

Refresh YouTube and try commenting again. The text should now be visible.

NOTE: Chrome no longer supports uBlock Origin. So, this trick won’t work on the Chrome browser. However, it should work on other browsers such as Mozilla, Brave, Opera, etc. 

5. Update the YouTube App

If you’re using the YouTube app and seeing black text while commenting, the app might need an update.

For Android:

• Open Play Store

• Tap Profile > Manage apps and device > Updates available

• Find YouTube and press Update

For iOS:

• Open App Store

• Tap your profile icon

• Scroll down to see if YouTube has a pending update

• Press Update

App updates often resolve UI bugs like this.

6. Rollback YouTube App to an Older Build

If the issue started after a recent app update, you can roll back to a previous version.

Steps (Android only):

• Press and hold the YouTube app icon

• Tap App Info

• Tap the three-dot menu and select Uninstall Updates

This will revert the app to its factory version. You can then check if the bug persists.
