Re-enabling the prompt to install extension updates

Perhaps you just like to be in control of things, or perhaps it’s not really that but the lack of notification that there was an update and now something isn’t working right. Well, was it an update or something else?

That’s where I’m coming from. I received a very brief installation complete/success sort of fade in/out notification while using Mozilla Firefox for Android today and I’m still not 100% sure which app was responsible. But anyway, I digress.

Digging around I found the following descriptions of the options via the old UI that was tweaked back around version 10.


The options dialog has an “Automatically Update: Add-ons” checkbox.


The add-ons manager has an “Update Add-ons Automatically” check menu.

This gives a good breakdown:

That these are different settings and how they are different is unclear. The first one controls automatic checking and should be titled something like “Auto check for add-on updates.” The second, controls auto installation after detection and should be titled something like “Auto install detected updates.” And ideally, they should appear next to each other.


This appears to control whether the user is notified

So, if I set extensions.update.autoUpdateDefault to false, extensions.update.notifyUser to true and leave extensions.update.enabled set to the default of true I expect to be notified when extensions are ready to be updated.

For the Android version, I came across extensions.autoupdate.enabled, and Google searches aren’t telling me much. Perhaps I’ll check to see if there is a SVN or Git repo and check the code for clues.


This Bugzilla page explains it well enough:

Background update of add-ons/addons: Make success notification/toast ‘Installation complete’ more informative or remove it

Edit #2:

I have extensions.update.enabled set to true which I hope is what caused Firefox to look for extension updates, app.update.autodownload set to disabled (through the official menu option) which I expect will stop automatic updates of the app itself and extensions.autoupdate.enabled set to false.


You Can Do It! A Beginner’s Introduction to Computer Programming


The author’s page for this book is now offline. Please see this post for more details, including where you can still obtain the library sources and other updated content for the book.

I picked up this book and the follow-up You Can Program in C++: A Programmer’s Introduction book several years ago while flailing about in an attempt to learn C++. The short version of why I didn’t succeed was that I didn’t have the required patience to take things slow and fully understand each new idea before moving on.

Well, I’m forcing myself to have the required patience this time around (started most recent attempt Sept 2011), and I’ve made good progress going through Ivor Horton’s Beginning Visual C++ 2008.

Now that I’ve made it through the first eight chapters, I’m seriously considering taking a break and going back to You Can Do It! A Beginner’s Introduction to Computer Programming. There are several reasons for this, and I’m thinking the biggest one is that both of these books by Francis Glassborow are sub-400 pages, while Ivor Horton’s Beginning Visual C++ 2008 is 1392 pages. To be fair, those pages are not only dedicated to Standard C++, but code specific to Microsoft Visual C++ and C++/CLI. Still, with only 543 of 1392 pages down, I’m thinking I need the emotional pick-me-up from completing a smaller book. Then I can return to that one.

All of that said, I’ve just started looking at the errata, the contents of the CD that came with the book and the latest updates to the CD contents and source code.

I had no idea how spoiled I had become from always heading to the website to grab the very latest and authoritative version of software/code. A few things I’ve figured out:

  • The CD contents are superseded by the contents available on the CD Substitute page.
  • The fgwlib library sources from the Resources page supersede the sources available from tutorial.exe on the CD Substitute page. Oddly enough, some of the comment misspellings that were fixed in the CD Substitute page are back in the latest fgw library sources, so it’s likely the author wasn’t using version control.
  • The Quincy download link on that page is no longer working.
  • There is a newer version of the IDE used by the book, Quincy, available here.

Bottom line:

The fgwlib library sources available from the Resources page supersede all other library sources.

Now that I’ve figured that out, I’m off to build the library to work with the latest MinGW install.
