Compared to Chrome (at the same browser window size), the image on Nightly looks better. On Firefox latest release the issue is clearly visible. Is this still reproducible on your end ? If yes, can you please retest this using latest Dev release and latest Nightly build (https://nightly.mozilla.org/) and report back the results ? When doing this, please use a new clean Firefox profile, maybe even safe mode, to eliminate custom settings as a possible cause (https://goo.gl/AR5o9d).

@Maruf, I cannot open the video files. Although I have installed latest codecs this error is displayed: "Codec not supported: VLC could not decode the format "SPV1" (No description for this codec)". Tried also with Windows Media Player and other players and couldn't open it. I did a bit of research and maybe https://goo.gl/byIWDd the "Direct Recording to MP4" was not checked when you made the exporting. Please, can you post again the videos in a compatible format?

Thank you. I see what you mean. But on other browser how does it look? Can you provide a sample of how the video should look? I've tried on Chrome and the video quality is the same. On Safari from Mac OS X, Internet Explorer and Edge, the video is not playing and the website is broken. If the browser window has a smaller resolution 600x500px the video has a better quality and if the browser window has 1500x800px the video has a lower quality.
In chrome the video starts playing immediately after the page load. But it does not happen in Firefox. And I find the site and object edges more perfect and smooth in Chrome.And I used same and same window resolution for both the browser.
