About this extension
SingleFile is an extension that helps you to save a complete page (with CSS, images, fonts, frames, etc.) as a single HTML file.

Getting started
- Wait until the page is fully loaded.
- Click on the SingleFile button in the extension toolbar to process and save the page.
- You can click again on the button to cancel the action when processing a page.

Additional notes
- Open the context menu by right-clicking the SingleFile button in the extension toolbar or on the webpage. It allows you to save:
- the current tab,
- the selected content,
- the selected frame,
- the selected link(s).
- Select "Annotate and save the page..." in the context menu to:
- Highlight text,
- add notes,
- remove content.
- You can also process multiple tabs in one click and save:
- the selected tabs,
- the unpinned tabs,
- all the tabs.
- The context menu also allows you to activate the auto-save (after pages are being loaded) of:
- the current tab,
- the unpinned tabs,
- all the tabs.
- Right-click on the SingleFile button and select "Manage extension" to open the options page.
- Upload pages to Google Drive/Dropbox/GitHub/WebDAV via the Destination section in the options page.
