I used Firefox for 5 years until I met my husband, who pointed out how much time I waste dealing with Firefox rendering bugs and freezing and how much it aggravates him. After the 15th time I switched to Chrome and it's helped my relationship grow. But I use uBlock Origin religiously so it's time to go hunting again...
Swiching from chrome to firefox at work, this was the final straw. Internet/youtube etc is almost unusable without uBlock origin. Glad I already use FF privately.
