I've tries about every extension saving a web page. This is the first one saving everything (html, css, js, video, images, background-images from css, etc., etc.)
Since I have a site myself, I can check easily if really EVERYTHING is saved. Every other extension didn't save one thing or another.
Excellent!!!

Bit tricky to setup (with server-side required for advanced functions), but after that, it's almost absolutely perfect.

Used ScrapBookX in the past to highlight webpages and saved them with UnMHT.

Currently using Nuke Anything, Page Hacker, and SingleFile addons to edit and save single file webpages.

There's no option to remove this addon's context menu, which only offers to capture, not edit the current page.

Would be nice to be able to access the "Edit tab" bottom bar with a keyboard shortcut.

EDIT: Thanks for bringing the functionality of ScrapBookX to the WebExtensions API. Don't know why, but can't find a simple editor or extension to highlight HTML text in webpages.

It did take some configuring, but I expected that. Once I realized that I had to reboot the web server for changes in the config to take effect, things moved much more rapidly. :)
At this point I have converted several books from Scrapbook X, and do not plan to look back.

真的很好～
終於從研究所開始的用 Scarpbook 所做的筆記
救回來了 感謝作者的無私的開發

在FF上觀看儲存網頁好用的套件，
最近在公司的Win7電腦或是家裡的Win10電腦，FF是更新到90版，原本開啟MAFF檔，使用作者你說的OpenMaffInFirefox.cmd，似乎不太行了，公司Win7，是在原檔案右鍵開啟要選擇OpenMaffInFirefox.cmd，無法使用，家中則是開啟MAFF檔後，會開一個新的google搜尋網頁的視窗，不知是哪邊出了問題。

the author fixed a bug for firefox rel 60 esr, now it works for many users using that older firefox release bundled with many linux distributions ! this is about the only alternative that supports the legacy maf format !

您好，首先感谢您的辛苦工作。但是遗憾的是这款扩展和原先的scrapbookx相比，在使用便利程度和功能全面程度上都相差很多，不知道能否做一款可以实现原来的scrapbookx所有功能和界面的扩展呢？非常感谢！

您好，貌似不允许我直接对您的留言进行回复。Scrapbook X 就是您开发的是吧？我一直在用，也因此我一直没有升级为Quantum ，但最近经过尝试后发觉Quantum优点确实很多，而且以前的不少add-on都找到了替代，唯独Scrapbook X 至今没有可以比肩原先Scrapbook系列的扩展出现。诚挚希望您在时间允许的情况下能够创设出一个可以比拟原先Scrapbook X的新扩展。我在其他主流firefox 论坛上也遇到过不少用户殷切盼望这个扩展能恢复继续。再次感谢！
