What feature does 55 block? Perhaps the ESR build of Firefox will help if its a plug-in like Silverlight or Java.

Generally, its not recommended to downgrade to an older version as it contains security bugs and vulnerabilities. For curiosity, how old of a version do you require?

It block the playing of locally save .swf files. FF54 or the latest version of.

Do you want to try this? I saw it on Reddit and since you are disabling a security-related protection, please use with care:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.

(2) In the search box above the list, type or paste plug*ht and pause while the list is filtered

(3) Double-click the plugins.http_https_only preference to switch the value from true to false

That worked, but decided on a different browser.

Aww ....... why  ? Anything we can do to change your mind  ?

Yeah, what ever you are doing with FF57, stop completely.

With FF57, FF just becomes Chrome and Edge with a different rendering engine that I am in no way impress by.

I am not going to use something that is worse than the product you have now. I am not going to use it, because I need Classic Theme Restorer to unfuck the UI that Mozilla has decided to fuck. And since they have no plans to support those kind of add ons, they can go fuck themselves.
