Copy PlainText Firefox

Copy PlainText

By: erosman
Copy Plain Text without any formatting

Features & Capabilities

Copy PlainText is a lightweight Chrome extension designed to remove all formatting from any text you copy. Before the text is saved to your clipboard, the extension strips styles, fonts, colors, and extra spacing, delivering clean plain text. It supports custom find & replace with strings and regular expressions, removes leading/trailing spaces and multiple spaces, and includes keyboard shortcuts for efficiency.

This extension respects your privacy by containing no tracking or advertisements. It also provides a neat paste plain text feature to ensure what you paste is always formatting-free. Apple/Mac users can adjust function key settings to properly use shortcuts. While current browser APIs limit making this the default copy function, Copy PlainText offers an intuitive way to maintain formatting-free clipboard content with helpful notifications and a user guide included.

User Reviews

Users broadly find Copy PlainText useful for copying/pasting large text blocks and multiple conversations, especially for developers. The tone is generally positive, with mentions like perfect add and Good Work Erosman. However, there are several recurring issues: automatic copy is not working for some users; compatibility problems on certain sites (e.g., we.telegram.org); and installation failures or corruption reported by a user. A few requests point to a missing or inaccessible menu in the latest FF release. Overall, the addon is valued for text handling but reliability and UX could be improved.
Pros
  • Allows copying and pasting multiple conversations (e.g., from Copilot).
  • Viewed as a good addition and praised by users (e.g., perfect add and Good Work Erosman).
  • Useful for developers and people who work with large amounts of text.
Cons
  • Auto-copy does not work reliably.
  • Doesn't work on certain sites (e.g., we.telegram.org).
  • Installation can fail or be corrupted.
  • Menu visibility/access and guidance can be lacking in some Firefox releases.

Works great

It works, it does what it needs to do. I use it often when website's format text strangely and I need to copy something, or when I need to paste formatted text into a text box. It's simple, but effective.

Is Copy PlainText 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.

Copy PlainText requires very minimum permissions.
