Shouldn't there be a "1.9.3 Branch" in the Version box for Bugzilla?

I tried out the Fx 3.7 Dev Preview Alpha1 released today.

* Browse to http://svg-edit.googlecode.com/svn/trunk/editor/svg-editor.html
* Notice the drop-shadow on the canvas
* Center the workarea so a corner of the canvas+shadow is centered in the viewport
* Set the zoom to 3490 (bottom-left)
* Notice the shadow is still present
* Zoom up to 3500
* Notice the shadow is gone and the entire canvas edge is blurry (half-pixel?)

No, because 1.9.3 development is happening on trunk.
Version: Other Branch → Trunk
There is now a smaller upper limit on the size of a filter (4096 x 4096) to stop you allocating all the memory on your machine and thereby screwing it up.

You might be able to manipulate the filterRes to work around this. Otherwise you're stuck with it.

I don't understand what is being displayed though.  Seems like Firefox should maybe drop the filter altogether if it's too large instead of showing some weird intermediate thing.
Depends on: 536444
It tries its best, poor thing :-(  It scales the filter to compensate which makes it blurry. You may be seeing bug 541270 causing the weird intermediate thing. That one isn't wontfix :-)
541270 is only for filters in html, although it may be that the same incorrect code exists for SVG filters once we figure out where it is.
