Like most Firefox users, I had a set of add-ons (a/k/a extensions) that I liked to use. There had also been some extensions that I had used in the past, but that had become superseded for various reasons. Some extensions were ready to use upon installation; others called for tweaking. This post offers a list of add-ons that I had found particularly useful, along with some of the settings that I preferred, and some additional comments. (The list had changed greatly in the past several years.) There are several things to note about this list:
- At this time, I was using Firefox Portable 31.2.
- Some add-ons were available only through their own homepages, not through the Mozilla add-ons site. In some cases, there may have been compatibility issues and other problems with add-ons not hosted by Mozilla.
- In various versions of Firefox, and at various times, there may have been other add-ons that offered better functionality than some of the add-ons listed here. To find these alternatives, I would read the notes on the Mozilla add-on pages (below), and watch what comes up when typing the name of an add-on into the search box on the Mozilla add-on site.
- A fast way of opening the Mozilla webpages describing these add-ons (and, optionally, of installing them) would be to begin with the Multi Links add-on. With Multi Links installed, drawing a box with the right mouse button should prepare all of the following links to open at once. (Draw that box along the left margin, to include links only for the titles.)
- In most cases, it would be duplicative to use the separate homepage links shown below. The homepage link would nonetheless be useful for some purposes. See the further discussion under the follow-on list of XPIs and Nearly Dead Extensions (below).

In addition to the foregoing, for some purposes I had found and/or tried more than one add-on. Here, I have listed several alternatives. It might not be necessary to use more than one or two add-ons within each of the following categories.

I also used Google Hit Hider by Domain to add an option of blocking certain websites from Google search results. That add-on required Greasemonkey 1.15 (homepage). I think I had also tried cliget in connection with Wget for one approach to backing up a website.
XPIs and Nearly Dead Extensions
Many old extensions became incompatible with newer versions of Firefox. The Mozilla add-ons page would indicate incompatibility by greying out the “Add to Firefox” button (so that the add-on could not be installed) and adding a remark like “Not available for Firefox 31.0.” If the extension was already installed, but was incompatible with a newer version of Firefox, it would appear at the bottom of the list of installed extensions (Firefox > Tools > Add-ons) with an indication of incompatibility.
But sometimes it was possible to make an officially dead extension live again. The following points offer a few examples. Note the advisability of backing up the C drive (if Firefox was installed) or making a copy or a zip of portable Firefox (wherever that portable version had been located) before proceeding with these experimental techniques.
This list also includes XPIs that, at this writing, were not dead. They are here because the following introduction to XPIs may be helpful in understanding them.
- Infolister. Not available for Firefox 31.0. A relatively recent review on the Mozilla page suggested Extension List Dumper as an alternative, but now ELD was itself outdated. A review led to a separate discussion offering updated versions of both. For my purposes, Addon List Dumper (above) was adequate. But if I had wanted to try installing one of these unofficial updates, the discussion provided links for downloading XPI or JAR files that the user could install via Firefox > Tools > Add-ons > click on the gear icon at the top > Install Add-on From File.
- Forecastfox Weather 2.2.2. Not available for Firefox 31.0. The homepage provided on that Firefox add-on page offers a Support link leading to a Google Groups discussion in which users considered several alternatives and workarounds. One such option recommended by several commenters: ForecastFox 2.2.4. I found an XPI copy on the apparently reputable (i.e., virus-free) FreewareFiles.com website. The list of add-ons in my copy of Firefox Portable 31.2 (i.e., Tools > Add-ons) accepted it, and it seemed to work, with a few missing features.
- Previously, I had updated my installed version of Firefox from a prior installation in which Forecastfox 2.2.2 was installed. In that case, Forecastfox was grayed out and moved to the bottom of the Firefox Add-ons list. I was able to restore it to use, without apparent problems, by using the Disable Add-on Compatibility Checks add-on to override Firefox’s objections. That approach did not work for some other outdated add-ons.
- Bargain Book Mole. Straightforward XPI.
Many add-ons had no options to set; in others, the default settings were fine with me. A few, like Tab Mix Plus, allowed me to export and import all settings at once, in the form of saved settings text files.
Here, for posterity, I offer screenshots of the settings I used in three of the foregoing extensions: Session Manager, Tab Mix Plus, and Google Hit Hider.
