Shady Medic (ID: 000000526f637e1d) Voted 4 ★ - Updated 06/08/2023 Works well enough, just one complaint: It also inverts the colour of highlighting, which isn't exactly wanted (see screenshot: https://prnt.sc/4-bvva7YCDD_). Thumbs up for inverting images though.

阿毛 (ID: 000000715707c198) Voted 5 ★ - Updated 02/25/2023 make shure let it access the url of downloaded pdf file, or it won't work. Nice plugin.

Bharath Bera (ID: 000000d5e4d026dd) Voted 5 ★ - Updated 12/12/2022 This extension just changes the PDF color to the opposite one, for example white to black and red to blue and vice versa. If someone find that it is not working, then give permission to read file and whenever you a PDF then click on the extension. I found it very helpful because while reading black color is preferred as it has less strain.
