Firefox (64-bit)

What's new in this version:

The Big Ones:
- A new color assessment mode is introduced into the darkroom. This mode is designed to ensure proper color perception based on ICC recommended (ISO 12646:2008) colour proofing conditions
- It is now possible to resize the left and right panels directly with the mouse. The positions of each one is remembered for each views' layout
- Add a focus peaking mode in the lighttable and darkroom. The default key to toggle this mode is Ctrl+Shift+F
- The wavelet denoise profile has a new Y0U0V0 mode. This new mode makes it possible to denoise the chroma and luma noise in a single instance

New Features And Changes:
- Add darkroom loading screen
- Make modules labels a bit smaller for better UI consistency
- Add small rectangle around the angle display when using the straightening tool for better visibility
- Ensure the different views layout are recorded. Many views (and mode like lighttable's culling or darkroom's color assessment), can have the filmstrip or timeline bottom widgets, we record the exact layout for each view and mode
- Add tool tips on module in history
- Add support for applying back the last added key-word with a simple key short-cut. Default short-cut is Alt+T
- Add wide-gamut HLG/PQ based color space P3 and Rec2020
- Add custom borders support in framing module
- Add standard variables support in watermark module
- Allow the same short-cuts to be defined by different modules. This makes it possible to have the filmstrip using the same short-cuts to set stars as the lighttable
- Add log editing support for the L, R, G, B, C, g blending modes
- This gives more control on the dark pixels
- Define many new accels for most of the sliders to allow more control using the keyboard

- Better visibility for the zoomed image part in the navigation widget
- Revert to smooth mode (was default in 2.6) in color zone module

- Module search in darkroom is now case-insensitive

- Make sure no more than 64 spots are added in spot removal module and display a message when the limit is reached
