Thanks for the screenshot. So many users fail to provide simple details.  ;-)) I have no issues, but this laptop is using AMD graphics. see screenshot X11 or Wayland? See what happens in X11 and I'll see what happens for me with another user in Wayland...

Operating System: openSUSE Tumbleweed 20251031 KDE Plasma Version: 6.5.1 KDE Frameworks Version: 6.19.0 Qt Version: 6.10.0 Kernel Version: 6.17.6-1-default (64-bit) Graphics Platform: X11 Processors: 16 × AMD Ryzen 7 5825U with Radeon Graphics Memory: 64 GiB of RAM (62.1 GiB usable) Graphics Processor: AMD Radeon Graphics Manufacturer: HP Product Name: HP ProBook 455 15.6 inch G9 Notebook PC

No issues for me in Wayland. see screenshot Maybe good old graphics issue. Try downloading Firefox from Mozilla, run firefox-bin from the folder and see if you have the same issue. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

Troubleshooting mode allow street view to work fine but normal mode don't work. André

What add-ons are you running?

hello. Thanks for your support. Only one extension is installed (Ublock) but is desactivated. If I use my 2 others computers, Streetview work ok on them even with Ublock activated. So, I am looking now the graphic card problem. The computer with the issue use a AMD Radeon gpu. But I am not at home now to specify the exact model. This detail will be displayed as soon I will be back home. I will also try the bin option to see if yes or no it work.

Roger that...

Back home now. I have the test with the Moziila tar. file and the result is the same.

Troubleshooting mode allow street view to work fine but normal mode don't work. André

It works in troubleshoot mode so I would assume the issue is the add-on. You don't have to remove it, but just it should give you some options to tweak the setting for the sites. I use Ghostery and it allows fine tuning on what's blocked per site. see screenshot

Also see what happens under a different user account.

hello. I have uninstalled Ublock now. No more extension with FF and the issue is still there. Uninstall FF completly including the configuration file .mozilla and reinstall FF with no extension and graphic acceleration unchecked... and nothing resolve this issue.

How about KDE?

If I use my 2 others computers, Streetview work ok on them even with Ublock activated.

So you know it's not a browser issue. What OS are on the other 2? Same graphics? If same OS, are the same packages installed? Try your OS via live usb stick. What happens with KDE?

If I use Chrome, every things works. If I use Linux mint ldme 6 on my little computer, it works.

I don't want to use KDE to test the issue because why using another distro when there is no issue in trouble shooting.

It remain very mysterious for me and I will rather use Chrome when using Google street hoping a new version of FF will resolve the case someday. Too much time spent for this issue when I have an alternative.

Thanks again for your help

Sounds like a plan, mark it as resolved and have a nice day. I also run more than 1 version of Firefox. This way my data is synced across several versions and devices. see old screenshot

Breaking news...

Mentionned a couple of times on the forums, I have tried couple things in the about:config.

The value "web.enable-webgl2" was set to true. I have change the value to false and .... streetview was working as it should be :)

Thanks

André
