Essential Mozilla Firefox/Thunderbird Extensions (Part II)

Here’s the second, completed part of my list about Mozilla Firefox and Mozilla Thunderbird extensions and hints I find very useful for my daily work (and yours too, possibly ;):

Essential Mozilla Firefox extensions

Web Developer
ScrapBook
Flat Bookmark Editing
savegenpage
DictionarySearch
Duplicate Tab
Bookmarks Synchronizer
miniT (drag+indicator)
Copy Plain Text
undoclosetab (undoclosetab.xpi for FF 1.0.6)
Chinese-English-Japanese Character Hint Bar
Digger

Other hints for Mozilla Firefox:

  • Click with the middle mouse button to open a link on a new tab
  • Click with the middle mouse button on a tab to close it
  • Hit CTRL-p to print a page which is loaded in a new window without any menu or toolbar displayed
  • How to make Firefox silently display error pages (like in IE) instead of the error dialog boxes: Enter “about:config” in the URL field and change “browser.xul.error_pages.enabled” from “false” to “true” (just click on the entry to switch it)

Essential Mozilla Thunderbird extensions

Enigmail
MinimizeToTray
Virtual Identity
Quote Colors
MessageFaces

Other hints for Mozilla Thunderbird:

Essential Mozilla Firefox/Thunderbird Extensions (Part I): ScrapBook

A useful Firefox extension for people who would like to share cached “bookmarks” between several workstations:

ScrapBook – Firefox Extension
ScrapBook @ Mozilla Update

BTW I had a similar idea for a long time. My architecture would be more flexible though, allowing any client (not only Firefox), not require any client-side configuration and provide even more useful features. I intend to implement it as soon as time permits as I really miss such a power app. In the meantime, ScrapBook serves as an interim solution.

New SSL/TLS certificates for numlock.ch

There are new SSL/TLs certificates for numlock.ch, valid through July 23, 2015:

SSL/TLS server certificates

Please delete the old certificates and import the new ones. Thank you.

For those who are interested in how to create TLS/SSL certificates for Gentoo, take a look at the Virtual Mailhosting System with Postfix Guide. In order to extend the validity of the certificates to 10 years, you need to edit a couple of files:

in /usr/sbin/mkimapdcert, replace

/usr/bin/openssl req -new -x509 -days 365 -nodes \

with

/usr/bin/openssl req -new -x509 -days 3650 -nodes \

in /etc/ssl/openssl.cnf, set

default_days = 3650 # how long to certify for

(note that strangely, the default settings in /etc/ssl/openssl.cnf override the custom settings in /etc/ssl/misc/CA.pl)

Toshiba Portégé M200 and Windows XP TabletPC Edition 2005 context menu lag solved!

By chance I seem to have finally “solved” the annoying context menu lag on my TabletPC! :)

How was it done? I just installed the “Matroska Pack Full v1.1.1” (which contains many common audio and video codecs) and enabled its context menu extension. The most obvious (but not necessarily true) explanation is that installing Matroska’s context menu extension somehow fixed the context menu bug which was presumably introduced by upgrading my TabletPC to Windows XP SP2.

Now I’m really happy that my productivity is not restrained by this bug anymore :)

IT trends and IT governance in Switzerland

An interesting study by Accenture about “IT-Trends und IT-Governance
in der Schweiz” (unfortunately in German only):

cio_survey_1104.pdf

Security awareness and IT efficiency/productivity improvements are top topics among CIOs in Switzerland for the next 12 to 24 months. The fact that most CIOs prefer standard software in the back-office and custom SW at the frontend remind a bit of the “window polishing” phenomenon known from management accounting but are in accordance with general business developments in highly developed and saturized markets (like in Switzerland). The products’s cores become more and more similar while the “wrappings” make the difference for consumers.

Free SIP client Gizmo: “Blind date” with Josef Estermann?

After having read about Gizmo in today’s issue of the Swiss newspaper Tages-Anzeiger (article not (yet?) online, unfortunately), I wanted to check it out myself. Downloaded it, installed it, did some echoing tests. Everything fine – Gizmo seems to be a pretty useful VoIP client, even in its early stage (v0.8 beta). It offers full SIP/VoIP compatibility (something Skype doesn’t offer), built-in call recording capability (dito), call in and out as a gateway to the POTS (as usual). As a first impression, Gizmo seems to be equal to or even better than Skype.

Now comes the funny side note: As most other software vendors entering a market where success heavily depends on network effects, Gizmo has a so-called tell-a-friend page. I usually ignore such pages as if, I prefer notifying friends myself (in order to not give someone else’s e-mail address to a potentially sneaky service provider) instead of sending an invitation through a web form. However, by clicking on a GUI element I just happened to be forwarded to this page.
The funny (or strange) thing about that page now is that if you take a close look at the bottom of the page, you can actually spot a picture of the former (and IMHO one of the best ever) president/mayor of the City of Zurich, Josef Estermann! The Gizmo guys were even unknowing or impudent enough to take his picture as a representative for the tell-a-friend message “Blind Date” (note that as far as I know, Mr. Josef Estermann is happily married to Mrs. Maggy Estermann):

I bet there are many ladies (and gentlemen, for equality) who’d like to have a blind date with Mr. Estermann (though it probably wouldn’t be a blind date anymore). I seriously doubt, however, that Josef Estermann agreed to have his picture taken for this advertisement. It might be just an unconscious mistake by Gizmo’s marketing department or the work of careless copy-cats. I guess it’s rather a funny coincidence/mishap than maliciousness, though ;)

Linux Device Drivers, Third Edition

A pointer by Tobias Klauser on the debian-unizh ml just reminded me of this great (and free! :) book:

LWN: Linux Device Drivers, Third Edition
