Although I don't use KDE as a whole (or any other full desktop environment), Okular is my main PDF reader. I'm having a mildly annoying problem with it, though: whenever I click a link, it tries to open it with /usr/lib64/firefox/firefox, which does not exist (I don't even have Firefox installed). I can't find any relevant options in Okular's settings to change its default browser. Copying the link address and using xdg-open launches my preferred browser as expected. I used strace -e trace=open okular to get a list of files/directories opened by Okular, but grepping those files for 'firefox' also came up empty (save for /usr/share/icons/HighContrast/icon-theme.cache, which I don't think is the culprit).

So does anyone have an idea how to get Okular to open links with another browser (apart from putting a shell script at /usr/lib64/firefox/firefox, which is an immensely ugly hack if you ask me)?

Cheers.

Solved by editing /usr/share/applications/mimeinfo.cache.

I'm not sure about using Okular in a non-KDE environment, but perhaps the following may help you:


To check the current association for PDF files:

Code:
$ xdg-mime query filetype sample.pdf
application/pdf


To find the Desktop Configuration File of the default application for opening PDF files:

Code:
$ xdg-mime query default application/pdf
okularApplication_pdf.desktop
$ locate okularApplication_pdf.desktop
/usr/share/applications/okularApplication_pdf.desktop


The file /usr/share/applications/okularApplication_pdf.desktop contains the following, which you could create if it does not already exist:

Code:

MimeType=application/pdf;application/x-gzpdf;application/x-bzpdf;application/x-wwf;

The permissions and ownership of the Desktop Configuration file are as follows:

Code:
$ ls -la /usr/share/applications/okularApplication_pdf.desktop
-rwxr-xr-x 1 root root 8512 Jul  9 23:49 /usr/share/applications/okularApplication_pdf.desktop


To associate PDF files with Okular:

Code:
$ xdg-mime default okularApplication_pdf.desktop application/pdf

Please read the question again, because that has absolutely nothing to do with what I asked. PDFs are associated with Okular just fine.

I found that the xdg utils look at ~/.local/share/applications/mimeapps.list, but ~/.config/mimeapps.list also exists. I removed it, and now Okular opens links with Google Chrome, which is also not what I want. However, symlinking ~/.config/mimeapps.list to ~/.local/share/applications/mimeapps.list still doesn't let Okular open links with my preferred browser for some reason. 8O

However, I just managed to fix it by editing /usr/share/applications/mimeinfo.cache.
