Tab completions
Troubleshooting steps for when Tab completions stop appearing or behave unexpectedly.
Why aren't Tab suggestions appearing?
- Plan limits: Free (Hobby) users have a monthly Tab allowance. Once it's used up, suggestions pause until the next billing cycle.
- HTTP compatibility: Some networks block HTTP/2. Go to Cursor Settings > search "HTTP Compatibility Mode" > enable it to fall back to HTTP/1.1, then restart Cursor.
- Outdated version: Press Cmd/Ctrl+Shift+P > "Cursor: Attempt Update" to check for updates.
- No internet: Tab requires a connection to work.
How can I improve Tab suggestion quality?
Tab builds context from your recent edits and the code around your cursor. A new or empty file gives it less to work with.
- Make a few manual edits first to signal your intent
- Check for conflicting extensions (see Extension conflicts)
What if Tab feels slow?
- Check your internet connection speed
- Disable extensions you're not using
- VPNs and proxies can add latency
How do I toggle Tab off for certain file types?
Click the Tab status indicator in the bottom-right corner of Cursor. From there you can disable Tab for specific file extensions (like markdown or JSON).
