Why Firefox

Why is Firefox 56+ required?

wget is an excellent & lightweight tool that does exactly what we need - collecting text from a page, but it doesn't follow hidden redirects embedded in Javascript.

We need a sneak attack that will let us scrape the page and can parse these "enhancements" in order to snag the text needed, without ending up with blank postings.

As of version 1.1.0 of Resgen, we're sending a headless browser after the posting, to simulate a user viewing the page.

Debian users: You don't have to rid Firefox ESR in place of 56+; simply install a new Firefox version and symlink it to your /usr/bin/firefox path so Selenium can see it. (ESR is /usr/bin/firefox-esr so the two can coexist, but firefox should point at your new install.)

Steps (Debian users / folks using ESR only; everyone else can ignore this section):

• Download Firefox
• tar -jxvf firefox*tar.bz2
• I downloaded Nightly & renamed the directory, just to be extra sure of no conflicts mv firefox firefox-nightly
• Move to /opt: mv firefox-nightly /opt/firefox-nightly
• Symlink it: ln -s /opt/firefox-nightly/firefox /usr/bin/firefox
• ls -l | grep firefox to confirm; good to go!

---

Note that when ESR updates, it will overwrite the /usr/bin/firefox symlink for Nightly once again; until ESR supports headless browsing, run the following:

• Backup the original symlink (just in case)

mv /usr/bin/firefox /usr/bin/firefox.orig

• Fresh symlink of the Nightly install to the /usr/bin/firefox target:

ln -s /opt/firefox-nightly/firefox /usr/bin/firefox

---

You don't actually have to use it for anything, other than letting Resgen use it as a dependency. This requirement is due to change as soon as ESR adds the headless feature.
