SingleFile can be installed:

• via the Firefox Add-ons website: https://addons.mozilla.org/addon/single-file,
• via the Chrome Web Store: https://chrome.google.com/extensions/detail/mpiodijhokgodhhofbcjdecpffjipkle,
• by downloading the zip file (https://github.com/gildas-lormeau/SingleFile/archive/master.zip) and installing it manually.

• Wait until the page is fully loaded, you may need to scroll down the entire page to be sure all elements are loaded.
• Click on the SingleFile button in the extension toolbar to save the page.

• To save multiple tabs, select them first and click on the SingleFile button.
• 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,
  • or the selected content,
  • or the selected frame.
• You can also process multiple tabs in one click and save:
  • the selected tabs,
  • or the unpinned tabs,
  • or all the tabs.
• The context menu also allows you to activate the auto-save of:
  • the current tab,
  • or the unpinned tabs,
  • or all the tabs.
• With auto-save active, pages are automatically saved every time after being loaded (or before being unloaded if not).
• Right-click on the SingleFile button and select "Options"/"Manage extension" to open the options page.
• The default save folder is the download folder configured in your browser, cf. about:preferences in Firefox and chrome://settings in Chrome.
• You can use the shortcut Ctrl+Shift+Y to save the current tab or the selected tabs. Go to chrome://extensions/shortcuts to change it in Chrome.
• See the extension help in the options page for more detailed information about the options and technical notes.

• You can save web pages to HTML from the command line interface. See here for more info: https://github.com/gildas-lormeau/SingleFile/blob/master/cli/README.MD.
• You can also convert MAFF pages to HTML. For this, you must use specific versions of SingleFile CLI and Firefox. See here for more info: https://github.com/gildas-lormeau/SingleFile/blob/master/maff2html/README.MD.

• All browsers:
  • For security reasons, you cannot save pages hosted on https://chrome.google.com, https://addons.mozilla.org and some other Mozilla domains. When this happens, 🛇 is displayed on top of the SingleFile icon.
  • The last saved path cannot be remembered by default. To circumvent this limitation, disable the option "Misc > Save pages in background".
  • The following characters are replaced with _ in filenames: ~, \, ?, %, *, :, |, ", <, >
• Chrome:
  • You must enable the option "Allow access to file URLs" in the extension page to display the infobar when viewing a saved page, or to save a page stored on the filesystem.
  • If the filename of a saved page looks like "56833935-156b-4d8c-a00f-19599c6513d3", disable the option "Misc > Save pages in background". Reinstalling the browser may also fix this issue.
• Firefox:
  • The "file name conflict resolution" option does not work if set to "prompt for a name"

Please follow these steps if you find an unknown issue:

• Save the page in incognito.
• If saving page in incognito did not fix the issue, reset SingleFile options.
• If resetting options did not fix the issue, restart the browser.
• If restarting the browser did not fix the issue, try to disable all other extensions to see if there is a conflict.
• If there is a conflict then try to determine against which extension(s).
• Please report the issue with a short description on how to reproduce it here: https://github.com/gildas-lormeau/SingleFile/issues.
