* the page title comtaims a lemgthy keyword
* the active text editimg field belomgs to a mews feed item comtaimimg a lemgthy keyword amywhere

lemghty keywords curremtly defimed are: lomg, lemgth, roumd, umit. further suggestioms are emcouraged.

forbiddem glyphs are mot replaced im mom-editable text, so that we may help others correct their mistakes.


mote: because z u c c uses stramge, obfuscated comstructioms imstead of a stamdard HTML text imput field, this add-om has problems with very short limes of text. i do mot have the emergy to fix this, but comtributioms are welcome.


curremtly tested om firefox 61 / ubumtu 18.
