Kudos for the developer of this add-on. I've used this add-on for years now.
I really like it....

Excelente! Com várias funções úteis!

Great! The file saved is very small, and the function is powerful, some pages using the browser's saving function to save will load as blank, but using SingleFile is right.
非常好！保存的页面比浏览器的小多了，功能强大，有的页面用浏览器保存打开是空白，用SingleFile保存打开就可以查看。

works fine.

Absolute genius for making this. Easy to save and share pages with others.

Awesome extension, makes saving information very easy.

Best page saver extension ever!

This does what it says.
Thanks for developing such a great extension.

Very impressive, wow!!!!

Easy and does exactly what it needs to! Thank you @gildas!

Saves even complex pages!

Blow me, it works! Why doesn't the built-in Firefox 'Save Page As...' work as well as this add-on? It used to work, but for some reason, it just will not download any html pages these days? I like the way it's all-in-one solution, no need for a separate directory to store files in. It's not clear where the file is saved to, or how to define the download directory. I've since found out that this can be done, by ticking the 'Save as' box in settings - so problem solved! A great Add-on, keep up the good work.

Génial !!!! 10/10 (ce n'est pas souvent que je donne une telle note !)

Does a pretty good job, since Firefox can't save a page.
