Clicking on entry should be Fill. Button to Fill should be changed to Edit and even better to small icon to leave space for clicking to fill and displaying entry data.
Reason for this is: the area for click should be based on frequency of usage, and the most frequently used function of entry click is Fill. Now it seems authors assume that most frequently used function of entry is view/edit, and using Fill is minor. It is plain wrong.
Please reverse meaning of entry click and small button to bring back usability of addon.
PS. Android app is better, clicking entry uses/fills data, not edit it.
Are you referring to the auto-fill suggestions or all entries? The latter could be a security issue because you could accidentally auto-fill entries on an untrusted site.
That highly depends on how the extension is used. For me, I do not use the auto-fill button because most of the time I can use the controls for form-fields without opening the extension.

This is only true when the app is opened during auto-fill to select an entry. If you open the app by itself and click on an entry, it is displayed normally.
