This is Firefox Support, and no tech to talk to. What are your issues ? As for Extensions look to see if the Developer has updated their page for Firefox 57 compatibility or for any notices. Developers are still coding for some. Others have said no do not want to learn new code. We do support for Extensions to the fact that it relates to Firefox and object is is to get Firefox up and running. Support Volunteers can't make changes to Firefox , but we can help you with troubleshooting your question. I would be happy to help. To submit suggestions for new or changed features, may I suggest: Feedback: https://qsurvey.mozilla.com/s3/FirefoxInput/ If you have a bug file a bug Bug Writing Guidelines Web Extensions are evolving and many of them are changing to be compatible with the new Firefox 57.
