Fix for zoomed default-font

This Add-On sets all form elements to 100% so elements where the font-size is not defined are not scaled by the text-scale-factor twice. This solves a wide spread problem on zoomed desktops.

Emoji Cheatsheet

just works Rated 5 out of 5 stars

I only had to change the setting to directly enter the character instead of the code, which was default.

Dorando keyconfig

Nearly Perfect (Thunderbird 45.5.1) Rated 5 out of 5 stars

It would be perfect, if there would be a button to disable all single-key shortcuts with one click:

Close Tab by Double Click

Super, wenn man keinen Mittelklick mit dem Touchpad hat Rated 5 out of 5 stars

Schön wäre noch, wenn kein Neustart beim Installieren erforderlich wäre.


must disable "delay at start" in Thunderbird Rated 3 out of 5 stars

the addon works only of you disable the hook "delay at start" in the preferences. otherwise there is no prompt at all and no mails can be loaded

Geniales Addon - macht häßliche Seiten schick Rated 5 out of 5 stars

Genial umgesetzt: man kann einfach auf einer Seite sagen "Style für diese Seite erstellen" und dann mit ein paar CSS befehlen die Seite verschönern.

Schön wäre noch, wenn man bestimmte Bereiche mit CSS-ids versehen könnte um Elemente anzupassen, die sonst nicht eindeutig anzusprechen sind

It would be nice if you could additionally define certain areas and provide them with user-defined CSS-IDs so you can match elements that are otherwise not clearly addressable with only CSS

Not working correctly on Firefox 38 with global zoom in Ubuntu Rated 5 out of 5 stars

A really nice tool, though it needs some fix for Firefox 38:

(I tried another idea with my addon zoom-menu-elements but it seems also weird since Firefox 38)

functions for keyconfig (Thunderbird)

This will break your thinderbird! What you are looking for is keyconfig 20110522 Rated 5 out of 5 stars

I installed this, and this will break Thunderbird 31 completely (see:
In case you installed this, you have to restart Thunderbird with "-safe-mode" te disable this again!


What you are looking for is the "keyconfig 20110522" Add-On, that is old, but still working:
To install this, you have to :

- right-click on the first word "keyconfig" in the old first forum post from "April 30th, 2004" to get the keyconfig.xpi file form here:

- open the settings for the extension "keyconfig 20110522", there you can change all key-shortcut, you like (for example disable single-key-shortcuts or "Ctrl+Q", which is my favorite ;-)

(My 5 stars count for that great Plugin)

Display Contact Photo

only one tiny bug Rated 5 out of 5 stars

This review is for a previous version of the add-on (1.2.5).  This user has a previous review of this add-on.

Display Contact Photo

Local Folder should also use random Pictures Rated 5 out of 5 stars

Great Work.

just some things missing, that would be cool:
if you select a local folder with pictures that are not named {email}.ending you select "use random pictures from folder" and then just any random picture is selected for your contacts each.

so you can create your own identicons.

and it would be nice to have these identicon providers too: Retro, vanillicon and Unicornify!
and then an option to pick randomly of one provider for each contact

This review is for a previous version of the add-on (1.2.5). 

Auto Compress File

Rated 4 out of 5 stars

Sehr praktisch und funktioniert beim Senden/Weiterleiten einer Email

schön wäre noch, wenn man:

Wenn man noch bei BMP Anhängen einstellen könnte, dass diese nicht gezippt würden sondern in PNG umgewandelt

eine vorhandene Mail, die man in seinem IMAP Postfach liegen hat mit einem großen Anhang komprimieren könnte ohne den Header mit Absender, Datum etc. zu verändern. (um den benötigten Speicherverbrauch seines IMAP Kontos klein zu halten)

This review is for a previous version of the add-on (0.2.6).
