Can Firefox read MHTML files?

General Linux Question
1

I have-you could say-a nagging issue with Firefox web browser.When Win7 was the default OS,Internet Explorer was the default browser.I didn’t see much of a problem back then but now,with Firefox as the default browser for any linux distro, i came to realize that a lot of files that i saved over the years come in a format that ‘the fox’ can’t read.
Recently i google for any plug-in,add-on or extension that would allow firefox to read those same files.I’ve red in some sites an extension called UnMHT but i’m having a hard time finding it.
What i would like to know is, has someone installed this extension and if it did, where can i find it.Or, as an alternative, should this extension not available for any particular reason, to install a new browser.If so, which one?
Thank you.

It looks like Chrome based browsers can open .mht files

Also, there is a ripper app which will extract the information from a .mht file

Have not tried it

And
There are online services that will convert mhtml to html

Last ditch method… you can open a .mht file in a text editor and hack out the info you want.

Following Paul suggestion, i went to website ‘addons.thunderbird.net’, download the extension but the thing is, it didn’t worked.Mint doesn’t allow the installation to carry on because the file"appears corrupted".
Neville posted that Chrome-based browsers can open .mht files.I’m going with that, i’m not seeing much of an inconvenience to have one more browser so, i would just that.Thanks.

I looked up UnMHT firefox extension
It says

Discontinued

Not supported since Firefox 57 (Quantum).

So Mint was right to reject it.

Thanks for the extra info I had not seen it had been discontinued thought it was still active but did not have a file to test it on

It’s a pity but in the end it doesn’t matter. I’ve searched for a chromium-based browser as a back-up browser and did the trick. It red my .mht files.So thanks for the advice.

I think you are better off without addons. There are security issues with addons and extensions.
