hello all, I'm running Firefox 115.18.0esr For a month now, tabs have crashed constantly. That is, *every single tab* crashes sooner or later and usually it's sooner. It's making Firefox unusable. I know my desktop is old and my OS is considered obsolete, but still, I'm a fan of Firefox and want it to work. I'm running OS 10.13.6 (which I can no longer update) on a iMac mid-2011. Any advice much appreciated.
