In the Tor browser user agent, the "geckotrail" part has been changed.
Apparently following an upstream change in Firefox:
> From Firefox 10 on mobile, geckotrail is the same as firefoxversion.

Note: I'm simply running latest Tor browser on Android and visit
websites showing the user agent to figure out the latest one. I tried to
figure it out from the source code once, but didn't find a place where
it could be looked up trivially (since it gets built of multiple
components etc.).

For some distros (including Debian), the Firefox config directory can be
different from `/etc/firefox`. Adding a variable for this location so it can
be easily customized at build time.

Preferences set with `pref()` can be changed by the user, but they're
then reset on each Firefox startup.

As users may want a different UA and keep it persistent, we should set
the default value with `defaultPref()` instead. This requires moving the
preference to the autoconfig file though, as `defaultPref()` isn't
recognized in the main config file.

To allow downloading the package directly from GitLab and not having to
run make install (e.g. to easily try a specific MR); also makes it
easier to check in a MR if make install works as expected.

Replace the generic addons links with ones that link to the addons for
the PC version of Firefox. Otherwise, because of the user-agent, we
would get redirected to the Android Firefox addons page.

Android addons are limited in their feature set.

Adds stylesheets for some "about:" pages, the pages were chosen depending
on importance for user.

preferences.css was moved to sidebar.css since changes in this file could
be applied for more pages and were related only to sidebar.

Only the first letter is capitalized according to Tor Project:
https://support.torproject.org/about/why-is-it-called-tor/.

addons.mozilla.org displays the following message when visiting it with
the Android Firefox user agent now, while also graying out the usual
button to install the add-on:
	You can install this add-on in the Add-ons Manager. Learn more
	about add-ons for Android.
It is not possible to use a different user agent just for this website
anymore, as it used to be with "general.useragent.site_specific_overrides"
(see https://bugzilla.mozilla.org/show_bug.cgi?id=1589607). Therefore,
just explain that one can press the "Download file" button to install
add-ons.

When trying to install uBlock origin as suggested on the start page, I
found that the text of the popup is taking up so much space that the
"Add" / "Cancel" buttons are missing again. Decrease the font size even
further (like in the "Site information"), so the buttons are visible
again.

If somebody wants to improve this: maybe we could give the
popup-notification-body a fixed height instead, and make it scrollable?
Patches welcome, and see README.md for instructions how to use the
Firefox developer tools with the browser UI itself.

Only apply rules from userChrome.css if the screen width is 700px or
less.

Remove the rule that makes it go 50px to the left and 20px to the right.
While this added some more space for editing the URL, it looked weird.
After having used it for a while, I think it's better to remove this
again.

This version isn't supported by Mozilla anymore, so drop related
configuration.

Give the file the same name in the source dir, as it will have after
installing.

The userChrome.css in the user's profile will be overwritten when the
package is upgraded.

Any change should therefore be made to the file located under /etc,
which should then be left untouched by most package managers.

Firefox can run an autoconfig Javascript on startup, which can be used to
install and update userChrome.css, both when creating a new profile and
using a pre-existing one.

This removes the need for a wrapper script and related complications
(changes to $PATH, different processing for new and pre-existing
profiles...)

In some cases, such as the ESR package on Debian, Firefox can be
installed to a different directory.

This commit alters the Makefile so it's possible to specify the Firefox
directory from the command-line.

That's what you get when using the gitlab web editor :p

This works in FF 68 ESR too, the previous rule did not.

The reason for disabling these was, to free up space in the menu. The
menu entry is hidden in userChrome.css now, so we can enable it again.
Having this enabled is required to use the Firefox remote debugger,
which is very useful for developing userChrome.css.
