As of Firefox 48, it’s impossible to disable mandatory addon signature verification without monkey patching Firefox or recompiling with MOZ_REQUIRE_SIGNING unset. Personally, I find this unacceptable as the user should always be in charge. It’s also completely useless as any party powerful enough to disable the signature verification in about:config could just as easily sideload a powerful (but signed) extension like greasemonkey and then install a malicious greasemonkey script.

Rants aside, the correct solution (for the user) is to either recompile Firefox with mandatory signature verification disabled or use the Firefox Developer build. Unfortunately, Firefox is a monster and recompiling it just isn’t a viable option for me (or anyone with a laptop). Also unfortunately, prepackaged Firefox binaries are missing some useful security features like PIE and dynamic libraries. Finally, the Firefox Developer build is a bit too bleeding edge for my taste (I would like my primary browser to be relatively bug free).

So, I’ve written a (disgusting) script that monkey patches Firefox’s omni.ja to make signature verification optional again. I’ve only tested it on Arch Linux but it should work on all unix-like systems. However, if your omni.ja file is not in /usr/lib/firefox/, you’ll have to tell the script where to find it (i.e., ./nosign.sh /path/to/omni.ja).

• Requirements: coreutils, gawk, python2, sudo
• Download: nosign.sh (signature)

NOTE: This script does not disable addon signature verification, only makes it optional. To turn it off, you still need to set xpinstall.signatures.required to false in about:config.

WARNING: This script updates the omni.ja file IN PLACE (using sudo).

WARNING: Use at your own risk.

I use MurrinaAngustifolium as my gtk theme but, because it is a dark theme, it does not always play nicely with other applications. One problem that I have finally fixed is the drop-down auto-complete menu for the location bar. Put the following code in your userChrome.css file (or use stylish).

@namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);
.ac-comment {
  font-size: 100% !important;
  color: #dddddd !important;
}
.ac-comment[selected="true"] {
  color: #56aaff !important;
}

.ac-url-text {
  font-size: 100% !important;
  color: #555555 !important;
}

.ac-url-text[selected="true"] {
  color: #666666 !important;
}
.autocomplete-richlistbox {
  background: #1a1a1a !important;
}
.autocomplete-richlistitem[selected="true"] {
  background: #000000 !important;
}
tooltip {
  background-color: #1a1a1a !important;
  color: #ffffff !important;
}

This code also makes some of the tooltips black.

Adblock Plus is a great Firefox extension that blocks advertisements. Advertisements hog bandwidth and are distracting. It is easy to use (right click and select block element).

Here is my adblock plus filter list (save it as a text document and import it).

(Adblock Plus 0.7 or higher required) [Adblock]

Caveat lector: I wrote this post in high school; it’s likely outdated and poorly written.

Taboo is basically a temporary bookmarks manager. If you have found an article that you find interesting but it is too long you would normally have 3 options.

1. Bookmark it.
2. Leave the tab open and move on.
3. Close the tab and find it in your history.

All of these options have one major problem: Clutter. Bookmarks can either be stored in a menu or the bookmarks toolbar. This is fine for sites that are frequented often or are permanent references but temporary bookmarks make the perminant bookmarks harder to find. A separate temporary bookmarks folder is fine but it can be very hard to find a specific bookmark mixed in with all of the other temporary bookmarks. Leaving the bookmark in your tabbar makes sorting through your tabs frustrating. The history is normaly erased after a set period of time ind is a pain to look through.

Taboo solves these problems. If you can’t remember the sites name, you can look for the thumbnail of the site. If you can only remember when you looked at the site you can view your taboos in calendar mode. If you know that you added your taboo recently (within the last 10 or so) you can use the menu attached to the “View Taboos” button as the list is sorted by most recently added. Taboo is a beta so more features should appear as time goes on.
