I'm trying to reset some strings in about:config, and I right-click them, but there is no reset option! How do I do this? I've tried in safe mode, but no luck!
If you can't reset a pref then the prefs already has the default value.
Which pref(s) do you have in mind and why do you want to change (reset) them?
Someone installed some video editing programs, and with the download some annoying programs/malware followed. The well known and annoying conduit search engine or what ever it is. So those are the prefs I'm trying to reset. The problem is, no matter what perf I try, the reset option isn't there. They're even say 'user set'! I'm at a loss...
Check for the presence of a mozilla.cfg file in the Firefox program folder to initialize some prefs.
This also involves the presence of a .js (JScript) file, probably in "defaults\pref" folder, that specifies to read this mozilla.cfg file.
If you have .js files apart from the channel-prefs.js file, that sets app.update.channel, in the defaultspref folder then open this file in an editor like Notepad and please post its content. Also please post the content of the mozilla.cfg file.
If you have this mozilla.cfg file then best is to do a clean reinstall of Firefox and remove the Firefox program folder.
