User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b1) Gecko/2007110904 Firefox/3.0b1 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b1) Gecko/2007110904 Firefox/3.0b1 The Resizer toolbar item only works properly when placed alone between the Address and Search fields. In any case where it's next to a button, using it can wreak havoc on button widths toolbar-wide; Icons get squished or padded, and aren't easily returned to default width. If the Resizer's only purpose* is to resize the Search field, and indeed it makes trouble when put anywhere else, then it should just be attached to the Search field. I propose borrowing the resizing code from the Searchbar Autosizer extension, if its author allows it. There's a step in its Configuration Assistant that lets you freely resize the Search field, and it doesn't squish/stretch your toolbar buttons in the process. http://searchbarautosizer.mozdev.org/ *: Even if there are items besides the Search field that might benefit from resizability (ex. Flexible Spaces), they are the exceptions. IMO it's better to make them intrinsically resizable on a case-by-case basis, rather than having a standalone Resizer that's useless or harmful in most positions. (I also think the Search field should only be resizable in Customize Toolbar mode, but that's a smaller, separate issue.) Reproducible: Always Steps to Reproduce: 1. View -> Toolbars -> Customize... 2. Place the Resizer next to a toolbar button (or vice versa) on the toolbar. 3. Close the Customize window, and drag the Resizer around until it starts squishing/stretching toolbar buttons. Actual Results: Various toolbar icons get squished or padded, and are difficult to return to default width. Expected Results: Toolbar button widths should not be affected by the Resizer, which in turn should not be independent from the Search field.
The resizer has been changed in recent builds to just appear in between the location and search fields always.
