User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.1) Gecko/20060315 Firefox/1.5.0.1 Build Identifier: Thunderbird version 1.5 (20060315) If a user choose "Download more dictonaries" option in the mozilla spell checker this page is opened in the browser: http://www.mozilla.com/thunderbird/dictionaries.html However the dictonaries are not saved in the profile folder but in the components/myspell directory that is usually not writeable by non-privilegied users. As a result by following the instructions from the site any non-privileged user is unable to install any dictonary. Reproducible: Always Steps to Reproduce: 1.Download or drag'n'drop any of the dictonaries from http://www.mozilla.com/thunderbird/dictionaries.html 2. Choose install extension as a non-privilegied user 3. "Access denied" message box pops up without any file/pathname in the message. Expected Results: At least - better error message. May be a way to install a dictonary by per-user basics (e.g. into the profile)? I think that similar problems may be reproduceable on other OS-s.
