what exactly is wrong in each of them ?
1. Incorrect dropdown size (+1px)
2. Input field located below
3. Same as issue #2
Select input has an extra 1px height in FF compared to other inputs
Fixed in svn://svn.zabbix.com/branches/dev/ZBX-10570
Fixed in pre-3.0.2 r59155 and pre-3.1.0 (trunk) r59157.
