Hi Patrice, I am very sorry for the inconveniences, and I am also very grateful that you wrote the coment to let me know. I just realiced that I made a very silly mistake in the code of the last version that made the extension fail and not load. I fixed it and it should work. The version with the fix is 3.8.4 and it is already available for Firefox. The Chrome store usually takes a bit longer to publish the changes, but it should be ready soon (I hope in a matter of a few hours). Again, thank you for let me know, sorry for the inconvenience, and I hope now everything works as expected.
