As a rough workaround, I've made a bash script called "bro" which handles the following:
―Image loading ON/OFF.
―Javascript ON/OFF.
―Plugins ON/OFF.
It works by modifying the standard Mozilla's 'prefs.js' configuration file (Sailfish stock browser is based on Mozilla). That way, you don't need to enter about:config, accept warning, search, modify and save.
Drawbacks: contrary to "about:config" way, it doesn't allow to make changes on the fly. You must first close browser, then open a terminal, execute the script, finally re-run browser. You must evaluate what is more comfortable and fast. Anyway, if it's just a matter of turning images off, I would recommend Webcat browser.
I ain't a programmer and my code looks horrific. Anyway, to play safe, the script creates a backup before modifying browser's config file. More info, see script's help.
INSTALLING:
―Open a terminal or log into your Sailfish device through SSH.
―Create a 'bin' directory in your home:
mkdir ~/bin
―Download the ZIP file (link below), extract a file called "bro" and move it into that 'bin' directory.
―Make it executable:
chmod +x ~/bin/bro
―Type 'bro', 'bro -h', 'bro -pleaseIneedtoknowhowtocontrolthisone' or 'bro -whatever' for detailed help/instructions. Examples for the smart ones:
$ bro i
# Disable image loading
$ bro Ijp
# Enable image loading, disable javascript, disable plugins
Download link:
bro.zip
And that's the script:
#!/bin/bash
# This script changes Sailfish stock browser's config (Mozilla standard
# 'prefs.js' file, located in ~/.mozilla/mozembed/), so user can
# disable or enable images, javascript and plugins.
PREFS_FILE=${HOME}/.mozilla/mozembed/prefs.js
PREFS_IMG='user_pref("permissions.default.image", 2);'
PREFS_JS='user_pref("javascript.enabled", false);'
PREFS_PLUG='user_pref("plugin.disable", false);'
