The Bugbug bot thinks this bug should belong to the 'Firefox Build System::Third Party Packaging' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Firefox snap esr works fine.
Installed it using the snap store.

version 140.0.2-1 has the same issue. I have always used the snap version and there have never been problems before.

I can confirm this issue. I found that this happens only under Wayland; under X11 I was able to use this package of Firefox 140 just fine. Reverting to Firefox 138 restored full functionality, even in Wayland. I am using Ubuntu 23.10 with KDE. I'm happy to run other experiments or provide additional system information.

Just confirming: Same version means 140.0.1 (that is the first dot release of 140) ?
Can you confirm you see also the same build ids in "Help -> About Firefox" ?

Firefox snap esr works fine.

Means 140.0esr ?

Reverting to Firefox 138 restored full functionality, even in Wayland.

What about 139, did you test it?

Note that I am not seeing any such issues with the snap release 140.0.2 on Wayland/Gnome (Ubuntu 25.04) here, so there might be either a KDE specific twist or even a single machine/configuration issue. If possible I'd recommend to test with a fresh installation to see if any profile specific things got in your way, maybe even for a different test user with a clean home.

I just installed firefox snap 140.0.2-1 on my kde box. It still is a mess.
I created a fresh/new user on my system and started up firefox there: also a mess.

esr version:
I took the first esr "snap search" had to offer. It worked great on my kde box.
I definitely believe that this is NOT a problem in my user-profile.
Thank you

Thanks for checking.

On my Ubuntu system that would be indeed 128.12.0esr-1, so a way older base version. That does not really tell us much, I fear.

Can you please give more details pertaining to the operating system? Info center > Copy details > Paste here.

I couldn't reproduce any of the problems on the current user ISO from KDE Neon Noble, Wayland.

Comment 8

[pieter kristensen]

Thank you for taking so much time

Operating System: KDE neon User Edition
KDE Plasma Version: 6.4.2
KDE Frameworks Version: 6.15.0
Qt Version: 6.9.0
Kernel Version: 6.11.0-29-generic (64-bit)
Graphics Platform: Wayland
Processors: 4 × Intel® Core™ i5-6300U CPU @ 2.40GHz
Memory: 8 GiB of RAM (7.6 GiB usable)
Graphics Processor: Intel® HD Graphics 520
Manufacturer: Dell Inc.
Product Name: Latitude 5480

But on my other machine it's exactly the same. After I send this reaction I will walk to it and send these details of that machine

[pieter kristensen]

Other machine:

Operating System: KDE neon User Edition
KDE Plasma Version: 6.4.2
KDE Frameworks Version: 6.15.0
Qt Version: 6.9.0
Kernel Version: 6.11.0-29-generic (64-bit)
Graphics Platform: Wayland
Processors: 4 × Intel® Celeron® J4105 CPU @ 1.50GHz
Memory: 8 GiB of RAM (7.4 GiB usable)
Graphics Processor: Intel® UHD Graphics 600

Still, the fact that it happens with a clean user profile seems to tell that the problem lies deeper than with the user...

So I tried to install firefox 142 alpha on the second machine.
But first I had to uninstall the current firefox snap package.
This seems to be not possible.
I did

• sudo snap remove firefox and after that
• sudo snap remove --purge firefox
  Than I rebooted and gave in the konsole
• sudo snap install firefox --edge, but the system returns
• snap "firefox" is already installed, see 'snap help refresh'
  Strange

Comment 11

[Nathan Teodosio :nteodosio]

Hi Pieter, thanks for your response. That is about the same operating system information that I collected in my tests. But I tested in a virtual machine. So maybe this is a graphics bug, bound to the graphics card. A screen-shot of the bug could help determining that; You could also disabling hardware acceleration in about:preferences in any case and seeing if it helps.

When a snap is already installed, you can directly use refresh (instead of removing and installing from a different channel):

sudo snap refresh --edge firefox

This is indeed a good testing idea, as Firefox from the edge channel is based in newer Ubuntu, with newer graphics packages than the one in stable.

Comment 12

[pieter kristensen]

Suddenly the firefox 140 snap seemed to be removed. So I installed 142 snap and it worked very well. Only, it doesn't respect de kde/plasma accent color.
Do you know if there is anything I can do about that?

Comment 13

[pieter kristensen]

Strange thing is, that until now firefox snap respected the plasma accent color always after I removed the package xdg-desktop-portal-gtk and after that rebooted the system.
That doesn't seem to work anymore...

Suddenly the firefox 140 snap seemed to be removed. So I installed 142 snap and it worked very well.

So the original problem is probably a core22 thing. If you want to stay in Firefox 140 but with core24, there is

sudo snap refresh --channel candidate/core24 firefox

Only, it doesn't respect de kde/plasma accent color.
Do you know if there is anything I can do about that?

No, sorry; Feel free to open a new bug about that, with snap info firefox; snap connections firefox attached.

:gerard-majax, could you have a look please?

While this is obviously not something we should ignore, IIUC there is a workaround in comment 14, so downgrading to S3.
