I tried going to Tools, Options, Applications but I don't know the file extentions used by most download files. What are the most common extentions used by downloading applications?

You should be able to set the default download location here:


Current Firefox versions remember the download directory based upon the URL, so if the URL changes then the default folder may be chosen if there hasn't been selected a download folder before for that server.
You can disable this feature to remember the download directory via the Boolean pref browser.download.lastDir.savePerSite on the about:config page.
The browser.download.lastDir.savePerSite pref doesn't exist by default (it is a hidden pref), so you need to create it.
Create a new Boolean pref with the name browser.download.lastDir.savePerSite and set the value to false.

You can delete the content-prefs.sqlite file in the Profile Folder to only remove settings stored in this file and keep the exceptions that are stored in permissions.sqlite that would be lost if you clear the "Site Preferences" via Clear Recent History.
