i am a regular user of Firefox but am disappointed with this latest version as there is one site in particular that doesn't appear to be rendered correctly.
I am an avid puzzler and regularly use the puzzle sites at www.puzzle-loop.com and all it's related pages (just click a puzzle type to load).
I am however finding that the rendering, particularly on www.puzzle-tents.com and www.puzzle-kakuro.com and www.puzzle-loop.com are frequently flickering between the correct rendering and something else (not sure how to describe it!) but it makes completing the puzzles quite challenging indeed as for quite a bit of the time you cannot see properly what the current puzzle status really is e.g. trees/tents not displaying correctly, the solution grid is not showing properly, or lines are missing from the overall solution.
It doesn't appear to be a memory issue as it only happens with Firefox (Edge <spit!> renders correctly)
It would be great is a developer could take a look and resolve.
