Like Microsoft Edge, the Firefox browser has a full-fledged PDF reader. What’s more interesting is that it allows you to edit and annotate PDF documents within the browser. In this article, let’s see how to enable PDF Editor in the Firefox browser and how to use it to edit and annotate PDFs.
What is PDF Editor in Firefox Browser?
The Firefox 106 update, released late last year, integrated the ability to edit PDFs in the browser. Using the PDF Editing tools onboard, you can:
- Add text to PDF documents.
- Check the boxes and radio buttons.
- Draw or add a signature to the document.
- Highlight text and add comments/annotations.
The PDF Editor, however, is disabled by default. Follow the guide below to enable and use it.

How to Edit a PDF Document in Firefox?
After enabling the editing tools on the browser, you can easily edit a PDF document within the browser, as shown below:
Step 1: Open a PDF document on the browser.
If you have a file on your computer’s local storage, right-click on a PDF file and select Open with Firefox.
Step 2: After it opens, you should see Text and Ink annotation icons on the toolbar. Tap it to open the PDF editor.
Step 3: Click on the Text icon on the toolbar menu.
Step 4: Select the text size and color for the text.
Step 5: After selecting, tap anywhere inside the PDF to add text.
Step 6: To draw something on the PDF file, click on the ink or pencil-like icon.
Step 7: Now, draw or write anything inside the PDF file.
Alternate Method to Annotate PDFs in Firefox
Mozilla Firefox’s PDF editing tool has only two options to annotate a PDF file. While it’s quite useful, if you want to add more highlights or shapes to a file, you need to install an extension or add-on on the browser like PDF Editor Online or PDF2Go. Alternatively, as shown below, you can use a PDF editor website like PDF2Go, ILovePDF, etc..
Step 1: Open the Firefox browser and open a PDF editor website.
Step 2: Visit PDF2Go on the browser.
Step 3: Upload the PDF document and select an editing feature to edit the PDF file.
Step 4: Once you are done with editing, click on Save to download the PDF document.
