Version 3.8.0
Released Feb 24, 2024 - 183.82 KB
Works with firefox 58.0a1 and later
The latest udpate includes:
* Now the results from the main document and from the ones in iframes are shown together. This makes the document selector no needed, so it was removed.
* When the extensions opens, the fixed elements are detected and moved based in the size of the panel. This is meant to prevent them to be hidden because the panel appears covering them.
* Resizing the panel can be done with keyboard. The resizer can get the focus. When it is focused, the arrow keys change the width of the panel.
* Other minor changes and fixes (better dialogs, font-sizes now use relative units, etc.)
