Description Zink Zxd 2025-10-07 17:43:24 UTC
SUMMARY:
When adding both Firefox and Waterfox icons to the quick launch taskbar, both icons will become Firefox or Waterfox.


STEPS TO REPRODUCE
1. Right click on Firefox icon in all applications and pin to task manager.
2. Right click on Waterfox icon in all applications and pit to task manager.

OBSERVED RESULT


EXPECTED RESULT:
It won't happen immediately but after a restart or two and a few browser sessions they will both become one or the other icon respectively.


SOFTWARE/OS VERSIONS
Operating System: CachyOS Linux 
KDE Plasma Version: 6.4.5
KDE Frameworks Version: 6.18.0
Qt Version: 6.9.2
Kernel Version: 6.17.1-2-cachyos (64-bit)
Graphics Platform: Wayland
Processors: 16 ร— AMD Ryzen 7 5800X3D 8-Core Processor
Memory: 32 GB of RAM (31.2 GB usable)
Graphics Processor: AMD Radeon RX 7700 XT

ADDITIONAL INFORMATION
Please update KDE to treat Firefox and Waterfox as two different distinct applications. The reason I use both Firefox and Waterfox is because I like keeping all my tab after closing my web browser and I have two screens. I use Firefox for the top screen to play DRM content and Waterfox to browse while watching DRM content AKA Movies/Shows. Just a note, LOVE KDE! Just a gorgeous babe of a DE! Keep up the good work and if any other information is needed, please feel free to contact me as this is my first bug report I've ever done.
Comment 1 Nate Graham 2025-10-08 19:03:47 UTC
Have both apps been installed from CachyOS's repos, or did wither of them come from Flathub?

Can you attach their .desktop files in /usr/share/applications/ ?

Hello and thank you for taking the time to investigate, Firefox came from CachyOS repos 

sudo pacman -S firefox

and Waterfox was installed from AUR thru 

yay -S waterfox-bin

AUR Webpage for Waterfox:
https://aur.archlinux.org/packages/waterfox-bin

I also want to note that I tried Librewolf install for my second browser and had the same issue. Librewolf was installed thru the CachyOS repos.

sudo pacman -S librewolf

Thank you for your time and please reach out if any other information is needed.

Thanks. Their Exec= and StartupWMClass= values are different, so there go my theories.
Comment 5 TraceyC 2025-10-15 19:25:35 UTC
I tested this on a CachyOS VM, and I can't reproduce the problem after opening both browsers and rebooting (and repeating 5 times)
The icons-only taskbar shows a Waterfox icon and a Firefox icon

Can you think of any customizations you may have made to either browser that might be related?

Also, can you try reproducing with a new user and with the browsers in their default state?
Comment 6 TraceyC 2025-10-15 19:49:29 UTC
After a little searching, I found an issue on the Waterfox issue tracker, with people saying the Waterfox taskbar icon is replaced by the Firefox icon. It's been reported as happening with Linux Mint, Xubuntu. There are comments indicating it might be linked to the language used on the system being something other than US English or if the system and interface language are different.

https://github.com/BrowserWorks/waterfox/issues/3743

On the system I tested on, the language was set to American English for both the system and Waterfox
I switched the language in Waterfox to French and rebooted, but was still unable to reproduce the bug
I switched the system language to also be French and rebooted, but still couldn't reproduce it
Comment 7 Zink Zxd 2025-10-18 18:14:10 UTC
I would just have both browsers open (One on each screen) and even while browsing the icons would both become one or the other in the task manager bar. Another note, I have not pinned Firefox and Waterfox to the task bar and I've had no issues with that. It's only when I pin the Firefox and Waterfox icons to the taskbar that I get the issue of both shortcut icons becoming Firefox or Waterfox. I would take a day or two for the issue to crop up.

Comment 8 Zink Zxd 2025-10-18 18:16:29 UTC
That was the attempted fix I tryed when asking ChatGPT where I would run the commands:


sudo nano /usr/share/applications/waterfox.desktop

and I would also edit:

nano ~/.local/share/applications/waterfox.desktop

Find and modify these lines:

Name=Waterfox
StartupWMClass=waterfox
Icon=waterfox

But I had the same issue.

Can you still try reproducing this with a new user and without making any changes to Firefox or Waterfox (aside from optionally pinning them to the taskbar)? Thanks.
Comment 10 Zink Zxd 2025-11-02 05:45:30 UTC
Hello, I have not been able to reproduce the issue again for the last 2 weeks. If it crops up again I'll reach out and I want to thank you and all the other staff members that reached out to me.

Thank you for your time,
Zink Zxd
