Content-Type Fixer

Firefox doesn't follow instructions for downloads? "Always Open Similar Files" is missing? This usually happens because the server sent Firefox a wrong/generic Content-Type header, or forces a download with Content-Disposition. Here's a fix.

2023-06-02 Firefox user 17926829 Thanks. I eventually got my .bib files opened by the correct application instead of being managed with the default Firefox option.

2022-08-08 raina Nice! Fixed my issue with https://addons.mozilla.org/en-US/firefox/addon/markdown-viewer-webext/ on Linux. I hadn't had issues with that extension on Windows and had set it to automatically open markdown files in Firefox. On Linux however, I got stuck in a loop where Firefox tried to open an .md file, spawned a new tab trying to do the same thing etc. With this extension, I was able to force the .md Content-Type to text/plain and finally view the file.
2022-07-03 Firefox user 14825171 not working :-( I need to download a file with the extension .adi from the program Lotw. That used to be no problem, but Firefox has recently updated and now it is no longer able to save that particular file with the extension .adi, Firefox does download the file but saves it without an extension, so I can't do anything with it. With another program where an adi file also needs to be downloaded the file is saved correctly with the .adi extension. Downloading the file with Edge does not give any problems ???
2022-06-02 Firefox user 13924257 With the extension, .acsm files are downloaded and then automatically opened. (I think that it's necessary to store the file temporarily... you have to remember to declutter the download directory every now and then.) I understand that section "add/edit content types" works only with new content types, since I did not see any file. [thank you for the quick answer! I am updating the review, since it seems to be the only way to answer back. And I will wait for Firefox 102 for changing the location of downloads :-) ]
