BMP File on Atlassian page has "Content Type=image/bmp" and Firefox will NOT open it

已張貼

My BMP files open from my Atlassian site in Chrome and IE but *NOT* in Firefox...it used to work but some version broke it. The "Properties" in Atlassian says "New Content Type=image/bmp" when you import a BMP file which works in Chrome and IE but I get a window with <The image "blah blah blah" cannot be displayed because it contains errors> in Firfox 72.0.1 under Windows 10 (and Windows 7). If I MANUALLY CHANGE every file to "New Content Type=bmp" then they will open in Firefox. Please FIX this..."image/bmp" and "bmp" are the SAME THING!

Attached is a sample file...no wait this will *NOT* let me attach a BMP file (apparently you just hate that filetype)!

I downloaded the image and that gave me the BMP image.

This BMP image has a 56 bit header (HEX: 00 00 00 38), so this special file format might be causing this problem.

It is not a "special" format, it is in both my link and your link as follows: 56 BITMAPV3INFOHEADER Not officially documented, but this documentation was posted on Adobe's forums, by an employee of Adobe with a statement that the standard was at one point in the past included in official MS documentation [11] Adds alpha channel bit mask. Adobe Photoshop

It is an OLDER (valid) format that everyone supports but Firefox!

Again, if I have Mozilla Firefox as my DEFAULT (as I do) and I click on a link to that document in EMAIL it works (shows the image), but if I click on a link to that document in a WEBPAGE it does *NOT* work (get the stupid cannot be displayed because it contains errors which it does NOT).

Clearly this is a Firefox Bug!!!

It looks that only WinBMPv3 with a 40 byte header is supported.

Please write a BUG for this (however you do that) to support this VALID format. This link shows the original (info), V2, V3 (that this file is), and V4 formats in an image where you can easily see the differences! https://en.wikipedia.org/wiki/Talk%3ABMP_file_format

Looks like someone broke ".MSG" viewing as well, I can no longer open saved Outlook Messages in Firefox! Chrome and IE/Edge work fine, in fact if I open the MSG file attached to my Atlassian JIRA in IE it opens! Sounds like another BUG report to me!
