[firefox] when scriptsafe is placed inside "extra menu" it doesn't resize the window to fit the content

[BrainDamage]

while using firefox, the extension works normally if added to the normal ui elements: however, if one were to move it to the "extra menu" ( right click -> move to extra menu ) now the extension doesn't try to resize the window and uses the same geometry as the extra menu size, which doesn't fit all the elements: however, other extensions such as ublock origin or proxy switch omega can resize the window to fit their elements, so it should be possible to fix it in principle
