I'm looking to switch from Chrome to Firefox for a myriad of reasons. I've been able to find feature and extension parity for just about everything. However, there is one issue that is holding me up and is a major deal-breaker. Compared to Chrome, text looks darker and less sharp, and certain images are pixelated. Attached is a screenshot from Facebook on Chrome and Firefox. Default text size/settings on both browsers, at 100% zoom. Chrome text and images looks clear and crisp on the left, Firefox text and images looks darker and more pixelated on the right.

System information below:

OS: macOS Catalina 10.15 (latest public release) Specs: MacBook Pro 13-inch, 2016, 3.3GHz Dual-Core i7, 16GB RAM, Intel Iris 550 1536MB Display: 13.3 inch 2560x1600 retina display Firefox: 70.01.1 (latest stable); ALL ADDONS/EXTENSIONS DISABLED Chrome: 78.0.3904.87 (latest stable)

I have tried all suggested solutions in the following links, including changing font smoothing via System Preferences, modifying font smoothing via terminal (defaults write -g CGFontRenderingFontSmoothingDisabled -bool NO/YES), and anything else suggested via the below links. NOTHING works. ... o_firefox/ ... ion_660b1/ ... hinting-on

Anyone have any clue how to fix this? I really do want to switch to Firefox, but I refuse to do so with this terrible rendering that i'm currently getting.

Any change if you restart in Safe Mode?

Is Hardware Acceleration enabled?
(I think that is about:support -> AzureCanvasAccelerated ?)
(Safe Mode disables HA.)
