Works but has a problem Rated 3 out of 5 stars

Works, but mp4 files served with MIME-type "application/octet-stream" open in the browser via plugin instead of showing the download dialog. I'm not sure how to fix that.

Works perfectly! (FF 19, Win 7)

Problem with .mkv files Rated 3 out of 5 stars

I noticed starting with FF 17 when you try to download a link to a .mkv file, FF will try to open it in the browser and fails saying the video is corrupt instead of downloading the file. Disabling this addon fixed it.

This user has a previous review of this add-on.

Great add-on, I was having problems with firefox not automatically opening .nzb files from a particular site automatically in my usenet client, even though I had ticked the "do the this automatically from now on" box and made sure the appropriate program was setup for the file type in firefox options.

This add-on has fixed the problem and now my .nzbs are opened automatically.

Many thanks to the dev =)

Thanks for making this extension and keeping it up to date. :)

Finally! A fix for this anoyance! Rated 5 out of 5 stars

Time after time I have researched this problem and all I could find was someone suggesting "how to's" for setting Firefox options or some story about the wrong MIME type. This is THE fix and it puts control of Save Dialogs back in the user's hands! Thank You!

Simply works Rated 5 out of 5 stars

I was very annoyed with how firefox handled the content attachment images after FF10. This add-on solved the problem easily, no more downloading of generated images!

Very tiny, restartless and useful addon for one who use torrent trackers based on torrentpier engine.

Amazing. Solves the problem with Firefox asking about torrent links all the time. Install, no options, no fuss.

Fantastic Rated 5 out of 5 stars

Now I can finally click external links from IRC or Instant Message chat that should automatically launch a viewer application without Firefox asking me "what to do" each time.

Doesn't work for pdfs? Rated 3 out of 5 stars

This works nicely for Word and Excel attachments. But not for PDFs which now don't open at all. So I've had to disable it and go back to the annoying situation where Firefox asks you what to do every time even though you've clicked "do this automatically from now on"

Was looking for this for ages! Thank you.. Rated 5 out of 5 stars

Brilliant simple add-on. Was looking for something this for ages. Agree with previous reviewer - please add something like "(Firefox Do this automatically)" to title so other users can find this easily!

Why doesn't Firefox integrate this into the browser? Rated 5 out of 5 stars

This issue has confused FF users for years, why don't do what this (excellent) add-on does by default?

Great extension Rated 5 out of 5 stars

Simple, restartless extension. I use this extension when I want to listen to ogg music files in my Ubuntu One storage. There is one problem, though: Text files w/o file extension cannot be shown in Firefox because they are recognized as binary files (but I think it's not the extension's fault, but a problem with Ubuntu One reporting a wrong file type or Firefox recognizing a wrong one)

I love this addon! It's gotten me one step closer to being completely unreliant on Flash.

Simple et efficace. Une fonction toute bête mais qui peut être vraiment pratique au quotidien car nombre de sites gèrent mal le téléchargement de fichiers. Merci!

Great extension! It solves Firefox's NZB problem wherein the user is always prompted with "What should Firefox do with this file?" even after he/she has checked "Do this automatically for files like this from now on". Now NewsBin will automatically load NZB files from BinSearch without the user being presented with a prompt. Thanks a million!

Excellent extension! It solves Firefox's bug #331259 and #236541

The Open in Browser extension does this and more:

InlineDisposition vs. Open in Browser

No, not really. While Open in Browser can ultimately accomplish the same thing, it is fundamentally different from InlineDisposition. Whereas InlineDisposition lets the browser carry on as if the attachment-disposition header was never set, Open in Browser was designed primarily to handle unknown MIME types, and as a *side effect*, it can also force open attachment-disposition content.

First, this means that InlineDisposition works automatically; if the browser supports opening a particular MIME type, it will, without the user having to instruct the browser to do so. With Open in Browser, you have to tell the browser to open the content inline (and what type to open it as) each and every time; for sites that use attachment-disposition extensively (there is a major image host that does this), Open in Browser is completely unsuitable.

Second, there is actually very little overlap between InlineDisposition and Open in Browser. In fact, the two extensions are complementary to each other: InlineDisposition is better suited for handling attachment-disposition issues while Open in Browser handles unknown MIME types. The two extensions can work alongside and in tandem with each other.

Third, because InlineDisposition is very limited and narrow in its scope (it targets attachment-disposition specifically and does not dabble in anything else), it also leaves a much smaller footprint. It is restartless, tiny (just 3KB in size), and works automatically without the need for user action/interaction.
