[SOLVED] How to open MHTML Web Archive files in Firefox Quantum?

Hi.

I have loads of .mht files saved on my HDD. I used the old addon UnMHT (no longer works) to do this. Now I cannot open the .mht files in Firefox Quantum. Is there some workaround? I get this [image attached] when I try to view them in Firefox - I select Ok but it continues to ask. I can open them with Chromium but prefer to use FF.

Thanks.

I think you should submit a bug request. As far as I'm concerned, I'm trying on my side to open WAF documents saved with MacIE 5.5 years ago with full functionnality, without success and being unable to find any information on the subject.

I wonder if there's a way to convert .mht files to .html?

Nt familiar with mht files, but I see two possibilities:

1. Open in Chromium, then save as html
2. Possibly something mentioned here: https://stackoverflow.com/questions/...iles-to-regula

I guess I could use Pale Moon just to read the 132 .mht files on my PC: https://en.wikipedia.org/wiki/MHTML#Browser_support

Another solution I may use is bit by bit, open the files in PM, then save as a 'Web Page, complete' - this saves it as a file and a folder. Then open that in FF and save as a single html file using the SingleFile addon.
