Considering Linux Lite as a lightweight distro

[Valtam]

Working with local files on Linux Lite can be a bit messy. For instance, HTML files may get executed as if they were
shell scripts rather than opening on the Firefox browser.

I guess that´s the only "negative" statement I found on the respective site.

Can anybody tell me what that might be all about? I´m not sure I completely understand what the author wanted to say.

For example if you're a web developer and you work with HTML files, some may try to execute instead of open with a browser. That's not a mainstream issue. Every one of our users, are not web developers
