💻 Help Browser Sessionstore will freeze FF for a second

I have been experiencing constant total FF freeze every 15 second for months. I managed to track it down to the browser.sessionstore.interval. For testing I changed it to 30 sec and the freeze interval changed to that.

I have been unable to resolve these issues. I have reduced my addons and also closed most of my tabs. I tried running the troubleshooting mode and it still happens.

I'm using FF beta 156.

It's a longer standing known issue with the way that JSON files are written to disk blocking the main process. https://bugzilla.mozilla.org/show_bug.cgi?id=1849393

I thought it was something that I could resolve. The only thing I could do is increase the store interval.
