• Check permissions: Extensions request access — read what you're approving
• Organize your toolbar: Pin essential extensions, hide others in the extension menu
• Regularly review: Uninstall extensions you don't use — they slow down your browser
• Keep updated: Enable auto-updates for security and new features

Conclusion

The right browser extensions can dramatically improve your writing productivity and quality. Start with the essentials (Grammarly, LastPass, WordCounter), then add tools that match your specific workflow.

Remember: tools are just tools. They can help you write better and faster, but they can't replace skill, practice, and creativity. Use them as assistants, not crutches.
