Push to Kindle for Firefox — Troubleshooting Common Issues

Push to Kindle for Firefox: Save Articles, Strip Ads, and Read OfflineIf you read long-form articles, research papers, or blog posts online, sending them to your Kindle can turn a cluttered browser session into a focused, offline reading experience. Push to Kindle for Firefox is a browser extension that simplifies this process: capture any article in your browser, strip away ads and extraneous layout, and send a clean, readable version to your Kindle or Kindle app. This article explains how it works, why it’s useful, how to install and use it, customization tips, troubleshooting, and privacy considerations.

Why use Push to Kindle?

• Read distraction-free: The extension extracts the main content and removes ads, navigation, and other noise so you get a clean reading view on your Kindle.
• Read offline: Once an article is on your Kindle, you can read it anywhere without internet access.
• Long-form content optimized: Kindle’s typography and layout are designed for comfortable long-form reading, reducing eye strain compared with screens and web layouts.
• Save articles for later: Instead of letting tabs pile up, archive interesting articles in your Kindle library to read when you have time.
• Sync across devices: If you use Kindle apps across phone, tablet, and e-reader, your saved articles stay synced.

How Push to Kindle for Firefox works

Push to Kindle generally follows these steps:

1. The extension extracts the primary article content from the page using readability algorithms (similar to Reader View).
2. It cleans the content by removing ads, sidebars, popups, and extraneous CSS.
3. It converts the article into a Kindle-friendly format (usually MOBI or AZW3; some versions support sending as PDF).
4. The extension sends the file to your Kindle address or stores it in a queue for manual delivery via email or a companion service.

There are two common delivery methods:

• Email delivery: the extension emails the converted file to your Kindle’s unique Send-to-Kindle address (you must add the sender address to your Amazon account’s approved list).
• Cloud delivery (if supported by the extension/service): the article is uploaded to your Kindle library directly via an associated server or service that integrates with your Kindle account.

Installation and setup (step-by-step)

1. Open Firefox and go to the Add-ons page (about:addons) or visit the extension’s listing on Mozilla Add-ons.
2. Install “Push to Kindle” (or an equivalent extension that supports Firefox). Click “Add to Firefox,” then allow needed permissions.
3. After installation, open extension options/preferences.
4. Enter your Send-to-Kindle email address ([email protected]). You can find this in your Amazon account under “Manage Your Content and Devices” → “Preferences” → “Personal Document Settings.”
5. Add the extension’s sender email to your Amazon approved email list (same Preferences page → “Approved Personal Document E-mail List”).
6. Choose default settings: file format (MOBI/AZW3/PDF), whether to include images, and whether the extension should remove article footers or comments.
7. Optionally configure a companion service or cloud delivery if the extension supports it (read the extension’s privacy notes before enabling cloud features).

Using Push to Kindle: practical tips

• Send a single page: Click the extension icon in the toolbar while viewing the article. The extension will show a preview and a Send button.
• Batch sending: Some versions let you queue multiple pages. Use this to compile reading lists to send in one go.
• Select text: If you only want part of a page, select the text you want and use the extension’s context-menu option (“Send selection to Kindle”).
• Remove images to save space: If you read mainly text on an e-ink Kindle, disabling images reduces file size and speeds processing.
• Use reader mode first: If a page has layout issues, switch Firefox’s built-in Reader View (the page icon in the address bar) and then invoke Push to Kindle for the cleanest result.
• Tweak font and margins on your Kindle: After delivery, use Kindle’s settings to set your preferred font size, typeface, and margins for best readability.

Customization and advanced options

• Format choices: If you prefer reflowable text, choose MOBI/AZW3 over PDF. PDF preserves layout but isn’t always optimized for small Kindle screens.
• Insert metadata: Some extensions let you add article title, author, tags, or the source URL to the document metadata for easier library searching.
• Remove paywall/limited content: Push to Kindle may not bypass paywalls or login-protected content. Using Reader View might help if you’re already logged in.
• Automation: Pair Push to Kindle with a read-it-later service (Pocket, Instapaper) that can auto-send saved links to your Kindle on a schedule.
• Keyboard shortcuts: Check extension options to assign a keyboard shortcut for faster sending.

Troubleshooting common issues

• Not receiving the document:
  • Make sure the extension’s sender email is on your Amazon approved list.
  • Confirm the Send-to-Kindle address is correct and that the device/app is registered to that address.
  • Check Spam/Trash for delivery failures or Amazon’s “Manage Your Content and Devices” for rejected documents.
• Formatting looks wrong:
  • Try switching output format (MOBI/AZW3 vs PDF).
  • Use Firefox Reader View first, then send.
  • Disable “include images” or “preserve original styling” toggles.
• Large files rejected:
  • Reduce images or convert to reflowable format.
  • Split very long pages into multiple sends.
• Extension fails to extract content:
  • Some sites use complex layouts or heavy JavaScript. Use Reader View or copy-paste into a plain HTML or text file then send.
• Privacy concerns about cloud delivery:
  • If the extension uses a cloud service to convert/send, check its privacy policy and prefer direct email delivery if you want local-only handling.

Privacy and security considerations

• Email delivery is simple and private if you trust Amazon’s handling of documents; however, the extension’s conversion step might pass article content through its own servers if it offers cloud conversion—read that extension’s privacy policy.
• Always add only reputable extensions and verify their permissions. Disable or remove extensions that request unnecessary data access.
• Keep your Amazon account secure: use a strong password and enable two-factor authentication.

Alternatives and complementary tools

• Firefox Reader View + Send by Email: Use Firefox’s Reader View to create a clean version, then manually email or upload the HTML/PDF to Kindle.
• Push to Kindle (Android/iOS apps): Mobile apps can send articles directly from your phone’s share sheet.
• Read-it-later services: Pocket and Instapaper integrate with Kindle via third-party bridges or paid features to deliver daily digests.
• Calibre: For advanced users, Calibre can fetch web articles, convert and sync to Kindle via USB or email with finely tuned formatting.
