This extension allows you to easily insert accented characters as you type in firefox or thunderbird. It is similar to abctajpu (which is no longer developed).

Features & Capabilities

This extension works a bit like abctajpu used to work: it allows you to type "e" followed by "" to insert "é", "a" to insert "à" etc. "" is the default trigger character, but this can be changed in the settings.

Settings

Trigger character

In the settings you can select the trigger character ("" by default). Any character can be used as the trigger but you should use a character that's easy to access on the keyboard, and which you won't need to use often in normal circumstances. When you type the trigger character, the extension looks at the characters immediately left of it, and if they match a key in the mapping (see below) they are replaced by the value found in the mapping.

Character mapping

An example makes it easy to understand how the mapping works:

With e:é,a:à as a character mapping, pressing "e" followed by "" replaces the inserted "e" with "é". With e:é:è pressing "e" followed by "" replaces the inserted "e" with "é", pressing "" again replaces "é" with "è".

The default is e:é:è:ê:ë:e,a:à:â:a,c:ç,o:ô:œ:o,u:ù:û:u,i:î:ï:i,$:€,d:°.

The mapping is a comma-separated list of key:replacement pairs.

Note that leading and trailing spaces in replacement values are removed. If you press the trigger after something not in the mapping, you get the trigger character unchanged.

Automatic uppercase pairing: mapping a lowercase letter automatically maps the uppercase version too. For example, e:é also maps E to É. You can override this with an explicit uppercase entry.

Some ready-to-use mappings:

  • French: e:é:è:ê:ë:e,a:à:â:a,c:ç,o:ô:œ:o,u:ù:û:u,i:î:ï:i,$:€,d:°
  • Spanish: e:é,a:á,o:ó,u:ú:ü,i:í,n:ñ,?:¿,!:¡,$:€,d:°
  • German: a:ä,o:ö,u:ü,s:ß,$:€,d:°
  • Romanian: a:ă:â,i:î,s:ș:ş,t:ț:ţ,$:€,d:°
  • Czech: A:Á,a:á,C:Č,c:č,D:Ď,d:ď,E:É,e:é,É:Ě,é:ě,I:Í,i:í,N:Ň,n:ň,O:Ó,o:ó,R:Ř,r:ř,S:Š,s:š,T:Ť,t:ť,U:Ú,u:ú,Ú:Ů,ú:ů,Y:Ý,y:ý,Z:Ž,z:ž,$:€
Snippets and multi-line expansions

Keys can be more than one character, making the extension useful for expanding abbreviations. For example:

ph:714 647 8181,ad:45 Rue de la Roquette

will expand ph</code> to your phone number and ad</code> to your address.

You can include line breaks using \n. Combined with multi-character keys this makes it easy to expand an abbreviation into a full multi-line block:

ad:45 Rue de la Roquette\nParis 75011

Note that line breaks only take effect in multi-line fields (textarea, rich text editors).

When multiple keys could match (e.g. both "a" and "ad" are mapped), the longest match wins.

User Reviews

Does not work! Typing \ after a vowel gives different accents but not all and seldom the normal Spanish accents. For example a\ with \ repeated does not give á.

Is AddAccents Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

AddAccents requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

AddAccents may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
