About this extension

Exception Notes

Version 1.7.1 ignores "Follow my settings (inline)" on Google Drive and for Gmail attachments due to cookie issues.

Operation

This extension does not monitor downloads until you enable it. Use the toolbar button to turn listening on (shows a yellow burst) and off (shows Zzzz).

Content-Type

The extension checks the file extension on new page and download requests to see whether they have a file extension that should be assigned a specific Content-Type header. (It doesn't look at requests for embedded items like images, audio, or video.)

Automatically corrects the Content-Type for these extensions: .acsm, .doc/docx, .epub, .pdf, .ppt/pptx, .psd, .rar, .rtf, .xls/xlsx, .zip, and .7z.

To add more, turn on the extension, try to download a file that isn't being handled correctly, then open the Log of recent requests to find Add and Edit buttons to add a custom Content-Type. The log is not saved to disk and is flushed when you snooze the extension.

There is a panel on the menu (starting in version 1.5) to individually enable/disable Content-Type overrides so you can have just the ones you need running.

Content-Disposition

The extension corrects errors with spaces that cause download file names to cut off. You can optionally force inline disposition, so Firefox follows the rules you've set on the Options/Preferences page without showing the download dialog each time. You also can force attachment disposition to bypass viewing in a tab. I suggest using that option sparingly, only as needed.

Permissions Note

While the extension is listening, it reads the Content-Type and Content-Disposition headers that servers send with files. It may modify the Content-Type and Content-Disposition headers. The extension does not read web pages.

Test Page

Without the extension running, you get bad results for the zip file links and embedded PDF on the following page, and the extension fixes it: https://www.jeffersonscher.com/res/badct/

Hat tip

The code draws from the Display inline extension from samlh: https://addons.mozilla.org/firefox/addon/display-inline/.
