Linux Dock Icon

more options

I am using Pop OS, which is based off of Ubuntu.

Somehow I did something, and it made the icon disappear for Firefox. I figured I could easily search the internet and find a simple solution.

I temporarily fixed it last night, but here it is missing again.

I could upload a picture, but I don't see what difference that would make. The dock at the bottom has a spot for firefox, but no icon, literally an empty spot, In the application menu it is a blank spot with Firefox worded underneath.

I have uninstalled, reinstalled, purged, deleted the application data in my user folder..

Just annoying. not a huge problem.

I ran "sudo apt-get purge firefox, I deleted the hidden .mozilla directory inside of ~/home, along with /etc/firefox/ & /usr/lib/firefox/

than sudo apt install firefox

and my icon is working again, hallelujah.

Hi,

First, I'll need to know if you installed Firefox through the PopOS repository, flatpak or Snap? You can type `about:support` in the address bar and copy/paste the `Application Binary` path.

I temporarily fixed it last night, but here it is missing again.

Do you remember what you did to fix it?

I have uninstalled, reinstalled, purged, deleted the application data in my user folder..

Did you also try to reinstall the whole application and not only the user data?

I have tried various forms of using terminal apt-get and used the Pop repository. I have been familiar with Linux for a few years, but it hasn't been my daily driver until the last few months, so if my terminology isn't 100%.

Binary: /usr/lib/firefox/firefox-bin


Last night, I went digging through the application files finding such as /usr/lib/firefox and other folders (from searching the internet for where ubuntu stores application data), and manually pointing to the firefox icon file inside of /usr/share/Icons (I think).

To the last question. I did apt remove, apt remove --purge, apt reinstall. and removing using the pop store and reinstalling through pop store.

Is your launcher icon or menu icon correct?

If you correct it, the dock icon will probably be correct as well. On my system (using KDE) I can change the launcher or menu icon so you probably can. My taskbar icon changed when I changed the launcher icon.

I don't know how

I'm not familiar with Gnome. You should ask at your distro's support.

If I right-click the launcher, I get the option to edit it. If I right-click the icon for the applications menu I get several options including one to edit the applications. Editing the Firefox application, there is an icon which I can click to select a different icon. You have to know where the icon you want is located.

I don't get any options to edit.

I am annoyed that I don't know what or where sets the icons for every other application to go to and fix firefox.

From the Pop OS Support site, these are the places I went to adjust the application icon, but obviously thats not where any of the applications get their icons set at ~/.local/share/applications /usr/share/applications /usr/bin /opt/

Hi

There is a guide in this support article to setting the application icon -

You should probably look for a subfolder labelled icons or something like that. My icons are in /usr/lib64/firefox/icons/ but yours are most likely in a subfolder of /usr/share/applications. If you download and decompress the tar from Mozilla, it may contain icons you can use.
