Finally gave up on Wallabag, an open source version of 'read it later'. this is in many respects, far superior to either! The only request I have so far is to have a default save to location other than firefox's default download folder. Yes, I know I can configure where to place downloads via 'save as' in ff, but this is a unique instance.

Take to much time for saving pages

' The most advanced tool for saving a webpage! '
Archiving always is a hard job but with "SingleFile" let's say WAS a hard job. SingleFile is the right add-on for saving a webpage as a whole and single HTML file which captures all the content just by one click. It saves your time in order to find the specific info about the original address (not the one on your hard drive) and the date that the webpage visited. There's also some more advantages to other available add-ons for saving duty as listed below:
+ Save hidden objects (like drop-down menus)
+ Much faster saving!!!
+ Save all open tabs by one click
+ Auto-Save
+ High compatibility by other browsers

Thanks for reading my review!

Очень не хватает возможности:
1. Показывать сохранять адрес страницы и отображать в всплывающей панели вверху
===========================
Very lacking:
1. Save the full address of the page and display it in the pop-up panel at the top.

Works very well.
Though, the size of the single html file is bigger, than the regular Save As files + folders total size.

Thank you.

I have to say, I have used this extension on Chrome and for me it is the best html save addon there is. Thank you for porting it to Firefox!

Very good alternative of the mighty Mozilla Archive Format plugin.

SingleFile incorrectly stores symbols with accented marks. For example, save this page: https://www.dumudaviklis.lt/dumu-detektoriu-montavimas/
and compare letters ū, ų, Ė...

Great extension!
Thanks!

I agree with a recycler.fox
Please write notes after the update

Works great. Will be even greater to see Release Notes - updates are so frequent that it raises curiosity and fear to miss a new feature.

Позволяет сохранить страницу в один файл. Это гораздо удобнее, чем стандартная функция.

この手の魚拓ツールでは「Mozilla Archive Format, with MHT and Faithful Save.（MAFF）」
https://cup.aihedy.com/en-US/firefox/addon/mozilla-archive-format/
が決定版でした。しかし、残念なことに「Legacy addons」になり、WebExtension の「API」により、廃版（更新不能）になってしまいました。WebExtension 規格のものに満足できる代替品が見当たらず、Legacy addons を使用できる Waterfox、Pale Moon を併用する動機になりました。

しかし、この「SingleFile」は「MAFF」と同等です。HTML ファイルを「単一のファイル」で保存できます。（標準実装「名前を付けてページを保存...」や他の同種の魚拓ツールでは、要素別のファイルが複数生成され、フォルダー管理スタイルでの保存になり、サイズが巨大になるうえ、再現性も不確実のものがある）
Github（https://github.com/gildas-lormeau/SingleFile）やサポートメールを通じて、迅速、且つ丁寧な応答が得られます。issue（解決すべき問題）や Requests（要望）が、直ぐに、更新版に反映されます。一日のうちに、何度も「更新版」が Release されるほどです。
たいへん真摯で、情熱溢れた仕事ぶりをされており、大いに感銘しました。

Really cool extension for OSINT. Much better than the regular "save page option".
Instant adoption for this add-on, I really already love it.
One suggestion : Could it be possible to generate a sha256 fingerprint of the fileat the same time?

Thank you!

Only just installed it, went through the settings and have saved a couple of pages, but it appears to do what it says on the tin.

I've found some pages will not save, however - The icon on the bar stays greyed out, and I get no action other than the page dimming when I click on the icon.

Will leave it installed and test it further.
