I haven't really used FF for anything but testing/bugfixes on web apps in several years. I do have a couple coworkers and friends that still swear by it.

Nevertheless, some third-party developers seek to modify the browser in ways beyond what is possible with a browser extension and resort to “hooking” the browser, effectively injecting third-party executable code modules into Firefox processes. Security software such as anti-virus products on Windows are the most prevalent examples. ( https://www.mozilla.org/en-US/security/third-party-software-... )

With Firefox 53, the ability to restore NPAPI plugin support will be removed completely. ( https://winaero.com/firefox-drops-all-npapi-plugins-except-f... )
Unfortunately, probably the browser that almost everyone else uses.
