On Debian buster, with v59, add on screen says I have v52, must upgrade

Hello, this may be a bug but it could also be just an environment setup issue. I am using Debian buster freshly downloaded last week (April 14th 2018). I downloaded firefox v59 alongside the original firefox v52 (ESR).

In firefox v59, I attempted to install the extension floccus. It has an error and claims that I am using FF52 and must upgrade. I attached a screenshot to show that I am in fact using v59, but the error persists. (WOULDNT LET ME UPLOAD?)

Any info would be appreciated!

I just noticed in the collected details that the User Agent String says v52, but the version is v59. That is probably the issue. Is this a bug?

In your More System Details on right of posts your useragent is showing as Mozilla/5.0 (X11; Linux x86_64; rv:52.0) Gecko/20100101 Firefox/52.0

Perhaps either you or a useragent switcher extension has modified the useragent to show as Firefox 52.0

However the likely reason is due to the privacy.resistFingerprinting being toggled in about:config from the default in which one of the things this does is change the useragent show as if you were using Firefox 52.0

Type about:config with a : in Location (address) bar and filter for privacy.resistFingerprinting and right-click this Preference and select Reset.

Thank you for the quick response! It was the privacy.resistFInerprinting setting. I toggled it back to the default and things worked as expected.

Have a nice weekend.
