'''Versions''': Firefox: 127.0 (64-bit) Linux: Ubuntu 22.04.4 LTS '''Description''': After some time, and (under unknown conditions), the input delay will shoot ''way'' up. Like 20-30 seconds. Strangely enough, this only applies to keyboard inputs. I can change my tab with my mouse, I can click on things, no issues there. But any keyboard interaction is hugely delayed. This does not fix itself until I close my browser and restart it. Closing the browser is always broken here too, if I close the browser with the [X] exit button, I then need to kill the process because it just hangs. It blanks out the contents of each tab like it's preparing to close them, but it just doesn't ever complete the task without a manual kill. CPU usage and memory usage are relatively low; significantly below my system's limits. I've already tried [https://support.mozilla.org/en-US/kb/accessibility-services#w_how-do-i-disable-firefox-accessibility-service this suggested fix], to no avail. The frequency of this is only about once a week at most, usually once a month, so it's not a huge issue, but I'm just worried about this occurring during a critical meeting or something later. Having this impending restart needed is kind of worrying for critical usage times.
