I have 4 languages (dictionaries) for the grammar check in Firefox. In theory, it should help me. In practical, anything i write it is underlined in red.
Why? Because I use all four languages, but Firefox is not clever enough to understand which language i am using. So when I write, there is 75% of possibilities that the text is underlined in red.
For example:
1. I write in italian, it is underlined in red. So after few lines i change and it's not underlined.
2. I open a new site and start writing in polish. Everything is underlined in red. After few lines i manually choose the right language it and it's not underlined.
3. So i open a new site and start writing in english. Everything is underlined in red. After few lines i manually choose the right language it and it's not underlined.
4. So i open a new site and start writing in esperanto. Everything is underlined in red...
5. So i open a new site and start writing in italian. Everything is underlined in red...
This is what I do for the WHOLE DAY. All the time changing language for spell check.
For example the current text is all underlined in red; but i am to tired to change it.
SOLUTION: make possible the use of many dictionaries at the same time OR make Firefox more clever so it can understand the current language before underlining.
