Summary of recent buggy Kindle updates since Nov 2025: dictionary, fonts, manga

Remember, Amazon can A/B test features, so bugs may only appear if a particular feature is being A/B tested on you.

09/17/2025 5.18.5

* No serious bugs as far as I remember.

11/05/2025: 5.18.6:

* Removed the ability to open a full dictionary in a book, not just a preview. "Open Dictionary" used to be in the spot where "Share on Goodreads" was.

* Removed the dedicated bookmarks bar

* German dictionary bugs * “I've highlighted the \[German\] word dahertrampelten for example. This is a separable verb with prefix daher. Before 5.18.6 my Kindle recognized this and would give me the definition of the entire word. After 5.18.6 it only shows me the definition of the prefix.” * “If someone actually needed to know what dahertrampeln meant, getting told the definition of daher would be [useless]”

* Japanese dictionary bugs * "the dictionary tries to default to looking up the shortest word of the highlighted \[Japanese\] text, instead of the longest.” * If the \[Japanese\] problem was present in English, it would look like: “You try to highlight "lighthouses". It highlights "light" and brings up the definition.”

12/10/2025 5.19.0-5.19.1:

* Kindle Scribe 2025 exclusive firmwares, but future firmwares inherit the problems

* caused battery drain during sleep due to infinite request retries for users using a custom DNS on their router since a certain domain is on a common default blocklist.

2/17/2026 5.19.2+:

* broke embedded fonts in AZW3/KFX books, where certain parts of text have an explicit font specified, often used for titles and headings. Now these are rendered with a generic font. \[fixed in 5.19.4\]

* azw3 books missing page numbers \[fixed in 5.19.3\]

* azw3 books % read tracker broken \[fixed in 5.19.3\]

* azw3 books laggy page turns \[fixed in 5.19.3\]

* azw3 manga/comics % read tracker broken \[partially fixed in 5.19.4\]

* azw3 manga/comics laggy page turns \[partially fixed in 5.19.4\]

* azw3 manga/comics all layout options missing in Aa menu

* added huge margins to mobi/azw3 manga/comics \[fixed in 5.19.3\]

03/27/2026 5.19.3

* Pulled after a few days, includes all changes in 5.19.3.0.1

04/07/2026 5.19.3.0.1:

* excluded Kindle Basic 11th Gen 2022 and Paperwhite 11th Gen so they didn't get any fixes

* Fixed various normal book azw3 issues previously mentioned, missing page numbers, % read tracker, laggy page turns

* Fixed manga margin issue previously mentioned

* azw3 manga/comics now show pages on the wrong side in 2 page landscape mode \[fixed in 5.19.4\]

04/24/2026:

* Kindle Basic 11th Gen 2022 and Paperwhite 11th Gen stuck on 5.19.2 would have azw3 manga margin problem fixed if they connect to wifi, they must have switched the A/B test off for the feature that caused the bug (the new UI)

05/07/2026 5.19.4:

* Pulled after a few days, includes all changes in 5.19.4.0.1

05/21/2026 5.19.4.0.1

* only for Colorsoft, Paperwhite 12th Gen, and Scribe 2022.

* full refresh option no longer does anything for azw3 books, both normal reflowable and manga. This may have been broken in 5.19.3.

* embedded fonts fixed!!!!!!!!!

* fixed azw3 manga landscape order problem

* fixed partially % read tracker for azw3 manga. previously it didn't work at all. now it works, but gets stuck at 100% at the end instead of marking as read. but other percents like 25% and 50% work now.

* azw3 manga page turn speed greatly increased, a tiny bit slower than 5.18.5 but way way faster than 5.19.2

* azw3 manga virtual panels still missing

05/20/2026:

* Amazon ends kindle store downloads via Wifi and registering 1st-5th gen kindles

* Kindle store downloads via USB were ended last year

06/02/2026:

* 5.19.4.0.1 released for Scribe 2025/2024 and Basic 2024

Kindle Basic 2022 11th gen and Paperwhite 5 (11th Gen) users are stuck on 5.19.2

    Windows

    Each story opens in a window holding its article above its discussion; drag the bar between them to share the room differently. A window can be moved by its title bar, resized from any edge, snapped to a half or a corner by dragging it there, maximised, or minimised to the bar at the foot of the page. Use Window > New reader window to open an empty reader, or Story > Open in new reader window to open another reader for the current article. Docked readers keep their articles when you select another story from the sidebar. Minimized readers can be restored and reused for their site. A window's Next story link reads on down the list in the same window.

    A link in a comment or an article to another Hacker News or Lobsters thread opens that thread in a window too. A link to a single HN comment opens the comment above its replies.

    While a story's window is in front, the Story and Discussion menus in the menu bar hold its commands: pinning, Next story, sorting, collapsing every thread, jumping to the first new comment. Each window also remembers where you were in its article and discussion, so a reload, or Back to a story that Next took you past, finds your place again. Closing a window forgets it.

    The whole arrangement lives in the address, so a bookmark or a shared link brings it back, and Back undoes the last change. Moving between Hacker News, Lobsters, their lists, Pinned and Find changes only the list, and leaves the windows open.

    The list

    The pin at the start of a row keeps the story in Pinned, and the cross at its end hides it. Pinned can be narrowed by words in the title, site or author, by source, and to the stories you haven't opened yet, and ordered by when you pinned them, by points or by comments; the filters are part of the address, so a filtered view can be bookmarked. Scroll past the end of the list to load more. Domain filters, in the View menu, hide every story from a site.

    Browsing view

    View > Windowed and View > Classic select the browsing view and save your default in this browser. Window view reuses a reader for each feed. Classic view opens stories and applets as pages. Open as a page and Open in a window are one-off actions that do not change your saved default. Direct page links always open as pages.

    Applets

    The Applets menu in the menu bar holds three tools, each a window of its own. Replies to me takes your Hacker News user name and lists the replies to your last thirty comments and stories, checking again every three minutes while it is open, and marking what is new since you last marked them read. Look up a user opens a profile on Hacker News or Lobsters, with their submissions and recent comments, as a commenter's name in any discussion does; the bar at the top of a profile looks up someone else in the same window, and Back returns to the one before. Who is hiring? filters the posts of HN's monthly hiring threads by the words you type.

    They read only what the sites publish to everyone, so none of them asks for a login, and your user name stays in this browser.

    Find

    Find takes any link and lists every time it was submitted to Hacker News and Lobsters, so you can read each discussion of it.

    About

    YAVCHN never sees your Hacker News or Lobsters login. The discussion is fetched from each site's public API; to vote or reply, follow the link above the discussion, or the arrow beside a comment, to the source's own site. Pins, hidden stories, filters and layout are kept in this browser only.
