Sorry, but this add-on is absolutely terrible...:

1. You have to download every web page TWICE to save it with Save Page WE. Why in the world should i download again the file that has already been fully loaded in a browser??? Mozilla Archive Format didn't have such an inadequate behavior.

2. Don't work without internet (even when you already have a fully loaded web page): If you are trying to save a web page without internet connection you will just save a plain HTML file without pictures etc. Mozilla Archive Format add-on didn't have this problem as well.

3. Many unsaved items or VERY LONG saving time and VERY BIG file size:
Mozilla Archive Format 6 sec. 1,2 MB. Almost all items are saved.
Save Page WE (Slow Resources 10) 12—13 sec. 2 MB. Many unsaved items.
Save Page WE (Slow Resources 1000) 93 sec (!!!). 30 MB (!!!). Almost all items are saved.

4. You can't save a web page before it's fully loaded in a browser. Mozilla Archive Format add-on didn't have this problem as well.

5. No option to save only selected parts of a web page. UNMHT add-on didn't have problems with that.

6. Sortable tables becomes nonsortable. Mozilla Archive Format have this problem as well.

Or it is stupid, or it doesn't work.

No link to message developer directly - would have avoided 1-star rating.
Have used Print Edit WE successfully in the past. Today, having trouble saving a page using Firefox, so installed Save Page WE. It just says "Operation already in progress" but doesn't actually complete.

It modifies the page!!! Randomly erases JS, rewrites CSS.
It DESTROYED thousands of files in my database!!!
DO NOT USE THIS if you care about the integrity of your data!

Complete Garbage. For years I used save as mhtml and UNMHT for saving YouTube and it was awesome. Mozilla removed them both when they upgraded and this is nowhere the same. Don't waste your time. Use Google Chrome. They do listen more to what users want. Mozilla is like Microsoft. When something already works great, they change it so it sucks.

It is a LIE that the addonconverts mht files to html, better to use addon "SINGLEFILE" using the "save all tabs" option of the open pages previously converted to html with firefox 56 with the "Mozilla archive format" addon.

I have a lot of TROUBLES with "Save Page WE" I do not recommend it

Utterly nonfunctional for my purposes. Needed to preserve a particular web page exactly as it currently displays for legal reasons, because I'm about to initiate a legal action for which material on the page is important evidence. As soon as the action begins, the sod operating the page will change it to hide the evidence, so I need to save it the way it is--and save it completely independently of the web. Everything has to be on my hard drive. Firefox's save complete web page is not working with this site, and the web page is too long, so Firefox's screenshot feature doesn't capture the end of the page--which is where my most important evidence is. So I hoped this add-on would take care of the problem. Unfortunately it doesn't. The right-click options are all greyed out, and when I use the Alt-A shortcut, WE saves only html, not resources. Open up the page source, and all the links point back to the original site.

So: didn't work for me at all. Complete failure.

Loved this add-on until today! It no longer works in either Firefox or Chrome.

It doesn't work at all. "35 of 35 ... could not be saved..." Trash.

It doesn't save the whole page, only the things that are currently displayed in the browser window. This is not what I expected from an addon with the name "Save Page".

This does not work as well as unMHT. When I save pages from the UK Met Office e.g. https://www.metoffice.gov.uk/mobile/forecast/gcqx6uk8k with SPWE I cannot open the tabs for the days of the week. But it works perfectly with unMHT. This add-on does not deserve even a single star.

Every time I'm trying to save some pages it doesn't works, and my Browser Console gets spammed with some Telemetry errors. I have telemetry completely disabled in my browser. At first I thought that's just the problem with some resources that extension trying to fetch from saved pages, but it happens almost every time. I'm not enabling telemetry for this.

It still light-years away from MAFF/UnMHT in terms of reliability, and it seems nothing's gonna change because Mozilla is too lazy/stubborn to add native support or at least proper APIs for something like .mht format.

It cannot save local files (like images etc.).

It cannot save complete pages with frames. For instance it is giving up with ebay items pages like this: ebay.com/itm/282768570260
Hit and miss for me. UnMHT was just perfect, I wish it to return.

ne sauvegarde pas les images malgré le réglage prévu pour.

Is it possible at all to provide the ability to save pages from the READER VIEW ?
