Versions 40 through 49
Firefox 43 is the first 64-bit version. https://blog.mozilla.org/futur...
Browsing web pages, watching YouTube videos (tested multiple quality settings, up to 4K), fullscreening YouTube videos, changing settings, re-sizing the window, entering full screen mode, browser extensions such as uBlock Origin, HTML5test.com, Wikipedia.org, Google.com, Reddit.com, WineHQ.org, any and all other tested websites.
What does not
The top bar is cut off when the window is maximized, the text on each tab is cut off. Full screen (F11) works fine, however.
Additionally, the top bar has distorted colors when unmaximized, until the window is resized.
What was not tested
I did not test every website on the Internet, obviously.
I did not install Flash to test Flash games.
Tested with these versions: Firefox 49, 32-bit and 64-bit. 4K video on YouTube had about double the CPU usage compared to native Firefox. That's acceptable, though, and quite niche. 463 out of 555 points on html5test.com
