I get the "Download failed" message after I click the "Add to Firefox" in Firefox 64.0.2 on both Fedora 28 and macOS 10.14.2 for dmitlichess 0.5.433. This is while my connection is fine (according to bmon) and the download seems to be progressing happily along.
Right-clicking and saving dmitlichess-0.5.433-fx.xpi (shasum: 82467dcadb4fc470c0e3673fa2774ea53fdba533) and then opening it with Firefox ends up giving the message "This add-on could not be installed because it appears to be corrupt."
However, installing Version 0.3.100 via the button at https://addons.mozilla.org/en-US/firefox/addon/dmitlichess/versions/ still works on both platforms (Version 0.5.432 states "This add-on is not available on your platform"). I can confirm that 0.5.432 does work on Chrome 71.0.3578.98.
Background noise / static is audible on a lot of Yasser sounds.
Some work should be done to reduce it. Could use lowpass/highpass filter on ffmepg or audacity noise reduction filters.
Currently using setTimeout and bad practices to make sure some required HTML elements are found the page when the extension is loaded. Need to figure a better and more consistent way to do this.
As I told you recently, lichess got a major upgrade. The HTML has changed quite a bit and as a result your most excellent extension is not working anymore.
Just a heads up in case you want to update it. The actual frontend of lichess is now stable and may be built upon.
i saw some people playing with dmitchess sounds on lichess, i installed it but it doesnt seem to work on chrome web browser. Does anyone have the same issues, or does someknow know a solution to this?
