For a long time have not found a replacement for unmht, until I found this addons, thanks a lot.
Here's a problem found with this page, https://blog.sina.com.cn/s/blog_17c8fdd330102z9hu.html . save selection, save to html, images can't be downloaded. After uncheck remove unused styles, the file became a bit bigger, but the image is still not downloaded. Some of my options are not correct?
Another page with the same content, https://www.meipian.cn/4xzu4yky, SingFile works perfectly.

Works very well for most web pages. Have saved hundreds successfully. Thank you!

But for very large web pages it brings up an error:
SingleFile error: [Exception... "Out of Memory" nsresult: "0x8007000e (NS_ERROR_OUT_OF_MEMORY)" location: "JS frame :: sandbox eval code :: replaceStylesheets/< :: line 3" data: no]

Would be great if this could be fixed.
Thank you!

Отлично! Все работает! СПАСИБО!!!

Works great and easy to use

Maybe the best offline page backup solution. Highly recommended.

It works well than simple downloading a website.However som interactive functions might not save into the file.But it is truly helpful on both Android and Windows system.
