Make firefox understand downloaded files
It is quite annoying that Mozilla Firefox always forgets what application to use for “opening” a file which you just downloaded. Also, the context menu “Open containing folder” in the Downloads overview does not work.
Using “xdg-open” you can improve the integration of Firefox into your Desktop Environment a lot:
- Delete or rename the mimetypes cache (where firefox keeps its file association settings):
- Download any file if you had not done this before
- Open that file from the “
Tools > Downloads
” menu (by right-clicking on it and selecting “Open
“).
When asked to choose the application for opening the file, browse to (or type) “/usr/bin/xdg-open
“, then check the checkbox to “Remember your choice
“.
After you’ve configured Firefox like that, both the “Open
” and “Open containing folder
” context menus will work. If you are running KDE then you can then change the preferred programs through KDE’s “file associations
” settings.
Enable the builtin PDF viewer in Firefox
The “pdfjs” PDF viewer is built-in in Firefox since version 15.0, this means that there is no need to install a PDF viewer plugin like Adobe Reader additionally. The built-in PDF viewer renders PDF using HTML5 and JavaScript.
The PDF viewer is disabled by default, but that is likely going to change in the future, when the functionality has proven itself. In the meantime, you can enable it as follows:
- In “
about:config
” set the property “browser.preferences.inContent
” to “true
”:
. - Also in “
about:config
” set the property “pdfjs.disabled
” to “false
”:
. - Finally, in the Firefox “Preferences > Applications” menu, search for the extension “
PDF
” and make sure the associated action is set to “preview in firefox”.
That's it! You don't even have to restart Firefox. Try opening a PDF, or even drag a PDF file from a filemanager into the Firefox window.

Content you don't need such as ads or tracking scripts can significantly slow down page loading. Firefox's built-in content-blocking feature can make the pages load faster by preventing third-party trackers from loading. See Enhanced Tracking Protection in Firefox for desktop for details.
There are also Firefox add-ons that can block content you don't need, such as:
- The Disconnect add-on blocks invisible webpage parts that track you online.
- The uBlock Origin add-on blocks ads, trackers and other unneeded content while using less memory and CPU resources than other adblockers.
- The NoScript add-on allows you to selectively enable and disable all scripts running on websites.
