Useful Rated 4 out of 5 stars

I hope that something like this extension will be WebExtensions-ready, for the release of Firefox 57.

An essential tool, but needs e10s update Rated 4 out of 5 stars

This is a great add-on, though it is reported as being incompatible with Multiprocess Windows (Electrolysis or e10s). I'd like to see an update so I can make use of all e10s features.

I use this frequently for loading podcast .mp3 files in my browser rather than an external app, the occasional video file, and it's frequently useful for viewing random text files (source code or configuration files) that would ordinarily be downloaded or sent to an external text editor. Usually I can just use "Server-sent MIME" as the file type, so I kind of wish that was the default option...

I really wish this was a built-in feature for Firefox.

It's very useful for me!

Trop bien Rated 5 out of 5 stars

Easy to install and useful everyday. Tiny & clean.
Très facile à utilisé et à installé, en plus ne prend pas de place et ne ralenti pas Firefox. Indispensable.

This review is for a previous version of the add-on (1.17).

Hoping it will turn e10s-compliant soon! ;)

This is very cool. I have been looking for something like this! It should be default in Firefox!

You need this! Rated 5 out of 5 stars

This is a brilliant little add-on. I've been yearning for something like this for years.
Of course the real fix should be on the server, where the mime type should be set to "text/plain".

edit after dev reply:
is it planned to be implemented?

Thanks for the review. This feature is not implemented, that's why the option is disabled.

Such a simple thing, but it makes a world of difference when one occasionally tries to open otherwise-uncooperative files in the browser. I recommend this extension for everyone.

Nothing spectacular but a reasonably useful additional option.

So handy !
Why isn't that included by Firefox ?
Thanks for this great simple add-on.

Does exactly what it promises, is very easy to use, but has two things which are rather irritating. Actions cannot be saved, and I get the popup twice. Going through a list of plain-text .log files becomes a headache.

Great add-on Rated 5 out of 5 stars

One of the most useful addons out there. Firefox really needs some built-in flexibility regarding MIME types. Until then, please don't let this addon die!

Useful add-on but needs some features Rated 4 out of 5 stars

Very helpful add-on.
But if you can add options window to set the default file type and ability to add custom file mime types would be great.
Also "Do this automatically for file like this from now on." option is greyed out when I choose open in browser so I can't set it as a default action.

This is extremely useful, as it means whenever i download a text file that's not in a .txt format [like a .sql file, for example], I can open it straight away. Great stuff.

Very useful, but lacks a few features Rated 4 out of 5 stars

Great add-on, FF should have an interface for setting preferred ways to open files based on their extension. I wanted to open .java with FF as text/plain. But after playing around with mimtypes.rdf, I couldn't succeed - I still got the DL window with "Open with" and "save" and it still displayed the .java file as "JAVA file".
Open in Browser lets me open it in FF as txt, but there should be 2 more features:
1. open in new tab - if I click the .java link in a new tab, it doesn't open the file. Also, even if it did, there's a problem for JS links, which you can't open in new tab.
2. I can't tell the add-on to always open files with a certain extension the way I want.

Overall quite useful and time saving.

Solves annoying problem Rated 4 out of 5 stars

Really helps me with my Firefox at Linux mint OS.
By default, FF tried to open application/json urls like a file. And in my work I extremely need such urls to be open just like text.

One note!
Currently "do this for all files of such type" checkbox is disabled for new option. It's will be very cool if this option could be saved. Because sometimes I use this option 5 times per minute ;-)

Great add-on Rated 5 out of 5 stars

Great add-on. I use it all the time when servers send files I can display in the browser but with the "wrong" headers.

Unfortunately, the add-on stopped working in Firefox Nightly (version 33). It still shows up but pressing the OK button does not do anything anymore. Can you take a look?
