When I use 'remember password' feature, which includes the account login, it automatically enters the values in any matching field the browser "finds" on the entire web site / domain, despite any value in the "value" parameter of the input element. 

For example, if i have a login saved and this input field is at another URL on the domain, like /plugin/example/info, then it is auto-populated with the login information stored in the database.

<input type="text" name="username" value="USE THIS VALUE BECAUSE I SAID SO">

the browser ignores "USE THIS VALUE BECAUSE I SAID SO" and instead populates with the stored username value, which is maybe something like "myloginusername".

In my opinion the stored login information should be tied to the specific URL logged in, and just the domain. This is potentially a security issue because (only for example) a "wordpress plugin" could have username and password fields that might not be apparent the to the user and falkon would autopopulate these and potentially transmit to undeserving third parties. there's alot of moving parts there but in principal it should only populate the account info on the specific login url where it was saved (when the user prompted to save it).
