New HP laptop, have used Firefox for years on old one, no problems. When viewing almost any video it gets completely pixelated (almost all the time) and unviewable. Contacted HP, they said (and showed me) that Firefox is using almost 100% of memory when viewing videos, hence the issue. Switched to Chrome as browser, no problems. Wondering why this is happening on my new laptop when I didn't have the issue before on the other laptops. Would prefer to continue using Firefox rather than Chrome but won't if this isn't resolved.
