I enjoy Firefox, but of recent it has become more of a problem than what its worth. My story is long but I will make it short. I live and work in China. I had to buy a Chinese computer. In switching it over to English they messed it up, plus you would not believe all the bloatware they install. Anyway, I got the free upgrade to Windows 10 and it worked well, but I still had a lot of problems, so I just completed the upgrade to Windows 10 and more of the problems disappeared but problems with Firefox happened, full web pages not displaying right. I finally did a clean install of Windows 10 which got rid of all the Chinese programs and leftover files. I downloaded Firefox and it worked fine for 1 day and then it started again. It would not remember my page visits, I had to sign in to each site, i.e. twitter, many times during the course of a day, so i uninstalled Firefox and downloaded it again and it worked, so I thought. It works fine, except some of my sites I go to, it only renders 3/4 of the page, which I don't need. Also when I imported bookmarks and everything over to Edge and Chrome I got my current bookmarks but I also got bookmarks that I had used on Windows 7 which I deleted a year or so ago, Figure that one out? So something is amiss and I don't know how to fix it except buy a new computer back in the states. I was going to use Tor for my back up, but that has the same problem as Firefox, so that is out. Anyway, its on to Chrome.
