Probably Bug 1866409 which is fixed in the latest Nighty (122.0a1). You can avoid it by disabling canvas randomization fingerprinting protection with a few different methods:

• Disable Tracking Protection for the site.
• Use Standard protection.
• Use Custom protection and untick "Suspected fingerprinters".
• Set privacy.fingerprintingProtection.overrides to -CanvasRandomization in about:config.

Also make sure privacy.resistFingerprinting is default false.

This article may shed some light. A previous reply by another contributor is, it seems, being moderated.

I've tried disabling all extensions and opening Maps in a private window but this did not help. Have tried shutting down Firefox, making sure all processes are gone, restarting Firefox, and loading only Google Maps; same fr problem, it immediately freezes.

I should have mentioned that this problem just started in the last day or so...up until then, Google Maps loaded just fine and had no memory issues on my machine.

Google Maps loads fine in the latest Chromium browser on the same machine. Problem is limited to Firefox. It could be something Google did in the Maps code that is breaking it. Hoping there is some debugging I can do that will shed some light on whatever is happening here. Would like any suggestions on gathering debug data that can be shared.

I have always enabled strict tracking in my Firefox settings...have not changed it recently...will try removing it temporarily to see if it makes a diff.

Can you provide similar info and screenshots? Let me boot up Tumbleweed. Also provide info from about:performance X11 or Wayland? What desktop? It would be nice if you could use OBS or simplescreenrecorder and post a video of the issue.

Not able to replicate the issue on Tumbleweed with several windows and tabs open. see screenshot

It is fixed in 120.0.1.

Can you make a live usb stick and boot it up to see if you have the same issues? https://download.opensuse.org/tumbleweed/iso/openSUSE-Tumbleweed-KDE-Live-x86_64-Current.iso

For what it's worth...Chromium Version 119.0.6045.159 (openSUSE Build) stable (64-bit) on this same machine does NOT have the CPU issue on Google Maps....it loads and runs just fine.

I am looking for the Firefox 120.0.1 patch release; once it is available for Tumbleweed I will update and re-test.

The problem was fixed when Firefox was updated to version 120.0.1.
