Anyone else have this issue? I thought maybe it was just my shitty surface pro 3 but it happens on my T530, T460s, and my desktop. I thought maybe it was an extension I had so I uninstalled them all except ublock. Still happening. For now I’ve just switched to librewolf and installed all the extensions I had on Firefox. Works fine and doesn’t keep my CPU at 100% so problem solved I guess, but I’m still curious if anyone else has this issue?

Sounds like a serious bug. What’s the distro and package format? It might be a single package issue.

Is your laptop linked to an external screen? Sometimes, I get the same problem and unplugging/plugging the screen solves the issue.

This will give you a good inkking as to what is happening in the background. We also need to know how you have it installed via rpm pack, or flatpak?

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
