Text Files

[Jason Jackson]

How can I have ESR 102 open text files in the browser?  I tried playing with Handlers > mimeTypes > text/plain, which is having some effect.  Should I use “path” to Firefox.exe?

 

I’m using this for testing: https://filesamples.com/formats/txt

I think that should work.

I can't figure out how this page is forcing the files to download instead of open. Usually it's Content-Disposition: attachment but I don't see that.

Hi Mike,

 

ESR 91, Chrome, and Edge don’t have this behaviour that ESR 102 has.  Should I submit it as a bug?

 

Follett Aspen is our student information system and it generates text files that trigger this.  It’s not a show stopper, but I imagine there’s others.

Interesting. I just tested on Chrome and Edge and both of them forced the download (they didn't open in the browser).

I'm going to check the ESR 91 and see what goes on there and see if something regressed.

It’s actually more complicated than I realised.  I’m now seeing ESR 91 and others do the download.  The difference seems to be whether the website decides to show a popup ad as a result of clicking the link.

 

In the case of Follett Aspen, the text file is in a popup window.

Out of curiosity I tried those links and they do open in the browser if
I open them in a new tab. I then inspected the page and see that the <a>
has a "download" attribute

Is this definitely a regression?

Any chance to use

https://mozilla.github.io/mozregression/

to track it down?
