1274648 - Reloading a temporary add-on does not refresh svg browser action icon

Status: NEW

(WebExtensions :: General, defect, P3)

Description

[Andreas Wagner [:TheOne] [use NI]]

STR:
1. Use an extension with a browseraction using a svg icon, e.g. https://addons.mozilla.org/en-US/firefox/addon/open-multiple-addresses/
2. Load the add-on using about:debugging
3. Edit the svg file in a text editor
4. Click "Reload" in about:debugging

Expected results:
browseraction icon should update

Actual results:
The changes are not reflected

Note:
Restarting the browser and clicking "load temporary add-on" does pick up the changed svg file

We probably need to flush the image loader cache after the reload.

Comment 2

[Kumar McMillan [:kumar]]

if it's a PNG you can change the icon, reload, and it works, so that's odd

Comment 3

I suspect that we have different cache behavior for SVGs, since they're much more expensive to rasterize than PNGs are to decode and scale.
