I see no point in keeping this to enforce a default that FF itself doesn't use - see https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/User-Agent/Firefox
- "... is an optional compatibility token that some Gecko-based browsers may choose to incorporate, to achieve maximum compatibility with websites that expect Firefox"
The last one-off ESR cycle of 8 releases is now behind us, new algorithm for FF60+ is back to 7 releases per ESR numbering, starting at 60... 67... etc. Note: This does not do anything for Aurora or Nightly spoofing the next ESR early (but we have until Nightly 67 before this becomes a problem). The ticket 1418162 was meant to cover this but instead was just used for the new algorithm. There is currently no ticket for the Aurora/Nightly issue - but never fear, Pants is here!! It is not forgotten, and I have emails with Tom Ritter et al on it
* updated shebang
* The script now compares its version number to the one online. If there is a newer version of `updater.sh` online it ask the user if he wants to download and run it.
* 2 parameters are supported: `-donotupdate` to disable the update-check and `-update` to auto-download and run the new version without asking
* Backup files are now saved to the directory `userjs_backups` instead of causing more bloat in the profile directory.
- massive speed improvement !! m-a-s-s-i-v-e !
- small fix to the time format used in backup filenames (replace space with zeros)
- better tolerance for special characters within preference names (which counters [the one downside that v1.2 brought along](https://github.com/ghacksuserjs/ghacks-user.js/pull/321#issuecomment-354394222)).
- other minor things, mostly to do with Delayed Expansion and the removal of it
known issue (but not really an issue):
- it skips instances of `user_pref` that have any quote or double-quote before `user_pref` (like `// "this" user_pref`)
