Although I have downloaded the English-language version of Firefox for NEW PC LAPTOP, the bookmarks settings appear in Dutch. How do I change this?
New Toshiba S50 Satellite PC laptop -- not Mac -- bought in the Netherlands, so had English language pack installed by dealer but they still loaded the Firefox--Dutch version (UGH!) ...uninstalled that and installed English version of Firefox, but bookmark settings are still appearing in Dutch....One user gave instructions for Mac (thanks) and have English appearing on all other apps and programs....

Otherwise, I believe a complete uninstall and reinstall in the correct language would be required. This would delete all your bookmarks, passwords and settings.
Try out the suggestions in the answers though, and see if they work.
Have a great day!!
