Firefox ESR Version 52.0 have problem with JavaScript/jquery function
Recently The Mozilla Firefox ESR browser was upgraded to Version 52.0 and I faced "few critical issues after updating".
"Few existing functionality is not working which was working perfectly before the update."
Error : JavaScript/jquery Error was thrown in Mozilla Firefox ESR browser Version 52.0 browser console alike “contains is not a function”.
But that "contain function" is working in previous Firefox ESR version.
So when I uninstalled the Mozilla Firefox ESR browser Version 52.0 and installed the Firefox ESR browser version 45.6.0. Here all my functionalities are working perfectly in Mozilla Firefox ESR browser Version 45.6.0.
Note: I am using jquery-1.7.2
I am not sure "Higher Version" than 52.0 of Mozilla Firefox ESR has also owned this same problem.
and also I am not sure, whether the "contains" is the only function which is not working but not aware of other functions.
Please let me know,
1. why am I facing this problem in the Mozilla Firefox ESR version 52.0?
2. what should I do to avoid this issue?
3. if possible, from which version to which version having this problem?
Kindly acknowledge to this.

Well Basically, we are validating the data using "contains" function using javascript/jquery.
it just couldn't find that function at all.
But it is happening only in the Mozilla Firefox ESR browser Version 52.0 and recently we are facing that issue in the 53.0 version also...
Not in the older version such as Mozilla Firefox ESR browser 45.9.0 or below
Kindly find the attached images, It would help more to understand the problem..

Thanks for your response..
I am not sure, whether the "contains" is the only function which is removed from firefox and I'm not aware of other functions.
May I know, is there any other function also got removed like "contains function" in the New Mozilla Firefox ESR browser Versions above 45.6.0
Everything's there => https://www.fxsitecompat.com/en-CA/versions/
Thank you very much
Will the javascrtpt/jquery supports libraries also get affected or won't work, due to "contains" function got removed from the Firefox.

I am not under the above answer,
My question is, due to the New Mozilla Firefox ESR browser Version which has removed the contains function..
will that affect the javascrtpt/jquery libraries files ??? file such as
jquery-1.6.2.min.js
jquery-ui-1.8.11.custom.min.js, etc..
The above javascrtpt/jquery libraries also has contains function
will that affect the javascrtpt/jquery libraries files ???
