Steps to reproduce:

0) English Wikipedia (not using Visual Editor)

1. Instead of editing the whole article, click "edit" link on a section only.

2. Crash the browser (in my case Firefox 26).

3. Restart the browser - the edited area of an article will not apply to the selected section but instead will apply to the whole article.

4. Saving changes will therefore result into removing all data except for the selected section, see example below.

E.g.:
https://en.wikipedia.org/w/index.php?title=Tourism_in_Tamil_Nadu&diff=594673990&oldid=593730355

db: Which browser do yo use?
Problem itself is confirmed hence changing status, but it's not clear to me whether there is anything that can be done server side or if this a browser issue.

db: Which browser do yo use?

I have only see the edits on my watchlist. I have not a problem with this myself. But for another case as from the links here (a half year or so), I read about a FireFox.

Tried to reproduce but failed:

• Firefox 27
• Created https://test2.wikipedia.org/wiki/Bug60744 with four sections
• edited section 3 resulting in the URL https://test2.wikipedia.org/w/index.php?title=Bug60744&action=edit&section=3
• crashed firefox by killing it: 32281 ? Sl 118:28 /usr/lib/firefox/firefox $:andre\> kill 32281
• restart firefox
• End up again on https://test2.wikipedia.org/w/index.php?title=Bug60744&action=edit&section=3
• Click "Save Page"
• Result as expected, other sections not deleted. :(

Try to crash the browser on preview or "show changes", than the url is action=submit and can make more trouble.

The text in the section should be changed before, FireFox mostly recover this changed text than.
