When I write an email in Mozilla, the spellcheck shows 21 entries for Spanish (Cuba, Ecuador, Spain ...) 3 entries for English (Australia, UK, US), 4 entries for French (modern, classic, reform, classic/reform). Is there a way to make it show up only the ones I am interested in (for example, Spanish (Spain), English(US), French(modern))? It is very uncomfortable to search for the language I need among them all. I found this bug report: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/651586 but seems it is not solved. Any clues? Thanks in advance
I finally found the solution: close Mozilla Thunderbird then
Obviously, instead of actually removing those entries, you can create a folder named "hide" and put the entries you don't want in it.
Now when you write a email and right-click, it only shows up English (US), Spanish (Spain), French (modern)
1) Select Languages
If you go to System Settings, the click on Language Support.
If you then click on the Install/Remove languages... button. This allows you to deselect/select the languages you want on your system.
Once the correct languages are selected, click on Apply Changes.
To sort them to your preferred defaults, click and drag the default item on the list of installed languages to the top of the list.
To make these settings apply System wide, click on the System Wide button
2). Regional Formats
The Regional Formats tab allows you to choose the way dates and numbers are displayed on your system.
I am not sure since I have not that many languages installed bud did you check the tools -> add-ons -> Languages section. can you disable the required languages?
