I didn't say it explicitly because I never bothered digging deeply into why it became so terrible - after being burned enough times by FF during that time period I decided to bite the bullet and switch over to Chrome since at my experience was at least more stable/had less breakage every update. Ironically enough it seems Chrome may be pushing some Extension API changes that will break things and force me to go back to Firefox. It's gotten to a point where I'd gladly use an old, insecure browser with features I like that enables a workflow I'm comfortable with than being force to use a more secure browser with all the features gutted or gimped. But I can't even do that because then every other site refuses to serve me content unless I update my browser to a supported version.
