Works ok, BUT..... Rated 2 out of 5 stars

"Open in Browser" works well enough but it would be EVEN BETTER if you were allowed to save your preferences for certain files. For example, I installed this add-on just so I wouldn't have to save every image I wanted to view. But now I have to tell Firefox to open the image in the browser everytime, which is what I was trying to avoid doing in the first place. Hopefully they can fix this in the near future with an update or two.

Very useful!

Feature suggestion: word-wrap. Unfortunately many text files are difficult to read without it (constant horizontal scrolling, back and forth!).

Great Rated 5 out of 5 stars

Fills the weird gap in firefox of really obvious and expected functionality: to open something in the browser when you use the browser to open it!

Works great, but a minor annoyance has popped up under Firefox 17 . . . The save dialog looks normal for most types, but the dialog for executables isn't resizing properly; and the buttons are half on screen and half off screen at the bottom of the dialog. Disabling this extension fixes the issue, and reenabling it brings it back.

Works sometimes. I have a financial site that uses Content-Disposition = attachment for pdf files. It also uses Content-Type = Application/pdf.

Even with this add-on, for this site FF asks me to save the pdf and does not display it in FF.

Note: that in Preferences > Applications "Display in Firefox" is selected.

Very good add on, I just wish I could change the default selection to Image instead of Text.

This addon realy should be built-in as others have stated!

Although it would be greatly appreciated if it would open documents in new tab instead of current open tab or at least a checkbox in settings that allows this.

Great extension, I hate some of the sites without these basic usability.

I notice a bug though. On wallpaperswide.com, downloaded images has open in browser as text by default.

Must-have feature Rated 5 out of 5 stars

This is a must-have add-on for anyone who often browses though various text files (source-code, TeX, etc) or mis-configured webservers.
It really should be built in to Firefox.
Agree it would be nice to see some integration with the Options/Applications page, so that the choice could be made permanent.

This is so fundamental that it should really be built-in, as RD suggests above. Brilliant extension nonetheless.

Particularly nice if your OS has various filetypes associated with a heavy IDE but you just wanted to look at one line. Stops you from having to choose save just to manually open in notepad/vim and then manually delete when done.

Should be normal browser behaviour. Essential Rated 5 out of 5 stars

This is an essential add-on until such functionality is integrated into the browser itself. (see https://bugzilla.mozilla.org/show_bug.cgi?id=57342)

Comes in handy when you encounter a misconfigured webserver or want to display files directly in the browser. I'm not a daily user but this add-on saved my day several times. :)

A must-have for me, I love the way Firefox formats different file types and it makes for easy tabbing between different types of files.
