KindBeamer од Juraj

Press the KindBeamer button (or Alt+Shift+B) on any article, and a tab opens
beside it with just the article: no menus, sidebars, ads or comments. It
keeps the text and its pictures, previewed the way the book will read.
Check the title and author, tick your Kindles, press Send.

• Extracted with Readability, the engine behind Firefox Reader View, from
the page as you see it, so articles behind a login or a subscription you
hold work too.
• Images are packed into a proper EPUB, converted where Kindle would not
take them (WebP, AVIF, SVG) and sized for an e-reader.
• PDFs open in Firefox go out as the file itself, with their original
layout or reformatted by Amazon to follow your Kindle's font size.
• EPUB saves the book to your disk instead of sending it.
• Straight to Amazon: sign in once on Amazon's own page and Firefox
registers as a device of its own on your account. No Send-to-Kindle
email address, no forwarding service, no server of ours. Nothing is
stored except the device credentials and your last choices.
• Keyboard-friendly: Enter sends, 1–9 tick a device, A takes all or none,
R switches a PDF's layout, Esc closes.

KindBeamer is also a desktop and Android app; see the homepage.
