Conflict between FF 37.0.2 and the Greasemonkey add-on extension disables some built-in Netflix features. Is a fix in the works?

After noticing that Netflix mouseover video descriptions were no longer working after the FF 37.0.2 update, I was able to isolate the issue (thanks to a suggestion from jscher2000 here: https://support.mozilla.org/questions/1059050 ). Even though my installed userscripts were functioning normally, having Greasemonkey enabled in FF 37.0.2 disabled the built-in mouseover descriptions for Netflix. Prior to the update, everything was fine. This issue is not present in Chrome or IE.

Disabling Greasemonkey solves my Netflix issue - but then all my userscripts are useless. I rely on Greasemonkey to enhance and personalize my web experience. I can only assume from some of the other questions posted on Mozilla Support that 37.0.2 creates issues with a number of add-ons and extensions. Is there a fix in the works, or should I downgrade to a previous FF version?

The changes in 37.0.2 compared to 37.0.1 are fairly minor (Release Notes), but some changes are related to compatibility with graphics card/chipset driver software, which could affect the display of overlaid information. Since the display works normally when Greasemonkey is disabled, I don't think that is likely to be the issue.

I suggest re-enabling Greasemonkey and investigating individual scripts.

While on Netflix, click the little drop-down triangle next to the monkey button on the toolbar, and look for checkmarks indicating a particular script is running on the page. Try turning individual scripts off to see whether you can track the issue down to a particular one. I think you have to reload the page in between changes.

Can you trace the problem to any particular script?

Ok, I found the culprit. It was the Disable Netflix Instant Watch Links script. It was useful because it allowed the user to click on a boxart image to get more detailed information without having the video start automatically. But I can live without it. There doesn't appear to be a recent update to the script.

Again, thanks for all the assistance!
