Doesn't work on Firefox for me, no idea why.

No intuitive way to access the custom save options, and not obvious whether the extension uses the browser-specific code to save pages rather than custom, or vice versa.

It works as claimed. However the downside I see with this add-on is the size of the generated files. After a short test I made downloading same webpages with SingleFile (SF) and Save Page WE, 50% of the times files were much smaller with SF, 30% of the time with SF were just smaller, 10% identical sizes, and only the remaining 10% of times files downloaded with Save Page WE were smaller.

Not as good as the late "Mozilla Archive Format".

How to save a fragment (part) of the page? For example, multiple lines.

In Twitter not working, when I save the page or direct messages the result is just a piece of speech
Please help and thanks
you told me
Unable to reproduce this problem. Is there anything special in the configuration of your Twitter account
Use Firefox Twitter, try to save a long conversation DM you find that not all messages in the conversation have been
Not everything is saved
Is there any solution

Seems to have problems saving Discourse forum threads

Das ist eine tolle Funktion! Gegenüber 'SingleFIle' fehlen die FUnktionen für Markierungen und das Entfernen von störenden Elementen.
Allerdings habe ich den Mehrwert noch nicht recht erkannt: wenn ich zum Beispiel eine Seite von Techstage speichere, funktionieren Galerien unter Verwendung der Speicherfunktion von Firefox einwandfrei – mit Sve Page WE jedoch nicht (habe eine Weile mit den Prefs experimentiert).

Malheureusement la dernière version 16.6 ne fonctionne plus. Se lance sans se fermer et n'enregistre pas la page. Revenir sur la version 16.5 corrige le problème.

This has the potential to be great add-on, but there are two glaring bugs:

1. The option to show warnings would should save the file without confirmation. It is incredibly annoying having to wait for the dialog book to show up in order to save the file! Note that I do want to see the warnings about resources not saved; however, I don't want to be "held hostage" by the need to confirm the save. I tried both "Show warning if any resources cannot be saved" and "Show list of all resources that cannot be saved", and neither does the trick

By the way, how do I send a donation? Implementing a third option like "After saving, show warning if any resources cannot be saved" is a no-brainer!

2. It doesn't allow the ability to save settings across machines via Firefox sync. This is incredibly annoying, because I use many different machines and VM's. If you can't implement readily, please point out a workaround. That would be another donation worthy fix.

I thought this might be a Firefox limitation, but I ran across the following Reddit comment suggesting otherwise when trying to find a workaround myself:
Firefox provides a way for addons to sync data: https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/storage/sync but it's up to developers to choose what they sync and what they keep in the local storage.
[via https://www.reddit.com/r/firefox/comments/7e8l8p/firefox_doesnt_sync_addon_settings]

Please make an attempt to fix them or offer good workarounds, so I can give you a 5-star review (It was a 4-star review, but I later remembered about point 2.) You might also try requesting that Firefox fine-tune its rating system, so I could have given something like 3.75.

Another annoying quirk is that there is no way to specify that the "saved" status be made permanent. This can be done stylishly by changing the "SAVE" to a light gray at the very end. A better way would be to omit the "SAVE", and just change the color of the icon gradually from dark blue to dark grey during the progress of the save operation. (This might be confused with the page-not-ready-for-saving color, but that color could be changed to a slightly brighter shade of light blue.)

If that were added, I can bring the review score back to a 4.

This addon mostly works fine, but it requires the "access-your-data-for-all-websites" permission.
At that point, I prefer to use "SingleFile", which also requires it, but it is recommended (and therefore I hope checked) by Firefox.

For details on the dangerous permission, see:

The extension can read the content of any web page you visit as well as data you enter into those web pages, such as usernames and passwords.

Unfortunately, there seems to be no way to choose not to save excess resources: images, stylesheets and fonts. Respective checkboxes are greyed out.

This extension does not make Firefox into a MHT reader, unfortunately. MHT files still can't be displayed.

We need such a plugin (on Windows) - I have zillions of old MHT files that I won't bother converting, especially since the format isn't dead in Chrome or Android. I keep an old version of Waterfox around just to read MHT (and remember my favorite FF plugins). With SingleFile and Save Page WE around nobody needs to WRITE mht anymore, but it's just lame Firefox is missing the capacity to read them.

The best addon for this purpose that I found and it was working properly until I upgraded to Firefox 72.0.1

Not all pages can be saved, even simple ones!

Take to much time for loading offline pages it will be better if I can see my offline pages in separate place or tab

An interface to manage saved pages is needed. For example a sidebar inferface like Scrapbook would be great.

many times can not save pictures, eg:articles of toutiao.com. not as good as unMHT.

Prior to your update of this add-on, I could save any .xml page as a single .html file with a single click. As of 5/19/18, I get an error message, it won't save it at all, and much time spent setting the options on the add on is fruitless. I have relied on this add-on for months to simply convert my newsfeed xml to a single html document for viewing online, and I've pointed search engines to this html file. Now this add on doesn't work do this at all, and I'm spending time on a Sunday I needed to spend elsewhere trying to fix something that wasn't broken to begin with. Please re-enable this capability with the awareness that I am experiencing real and significant harm by relying on an add-on your making it available invited me to use only to suffer precisely because I accepted your invitation to use it. By any reasonable standard, that's not good.

Unfortunately, it doesn't save personal entries and comments on any website, so disappointing.
It also has some issues with certain websites like ebay.

UnMHT was working fine but Save Page WE doesn't work fine.
Can you try to save this site?
http://animatorexpo.com/girl/
I was used this settings;
10 Maximum depth of saved nested frames
100 Maximum size allowed for a resource (MB)
60 Maximum time for loading a resource (secs)
It is downloading all sources but image slider doesn't work. I was tried with UnMHT and image slider worked.
Please fix this bug. I will give you 5 stars. We need really good extension. RIP UnMHT.
