[Pkg-mozext-maintainers] Bug#954097: ublock immediately turns off on chromium

[Olivier Cailloux]

Package: webext-ublock-origin
Version: 1.22.2+dfsg-1~deb10u1
Severity: important

On Debian stable, with current versions of chromium (80.0.3987.132-1~deb10u1)
and webext-ublock-origin (1.22.2+dfsg-1~deb10u1), ublock is not useable in
Chromium. Its icon (next to the address bar) indicates it is turned off (as
indicated by the tooltip and the grey icon). Reloading it (in the
chrome://extensions/ pane) briefly switches it to on (the icon turns red), only
to come back to off about two seconds later.

The console (visible through the background.html file that I can access when
turning Developer mode on in the extensions pane) indicates: “Failed to load
resource: net::ERR_FILE_NOT_FOUND” about chrome-
extension://oaiejdmjbagonijfeleeodihcicadkpm/lib/publicsuffixlist/wasm/publicsuffixlist.wasm,
and indeed this file does not exist: the debian package provides
/usr/share/mozilla/extensions/{ec8030f7-c20a-464f-9b0e-13a3a9e97384}/uBlock0 at raymondhill.net/lib/publicsuffixlist/wasm/publicsuffixlist.wat
instead. But I don’t think this is related: adding a symbolic link from
publicsuffixlist.wasm to publicsuffixlist.wat in that folder and reloading
ublock makes this error disappear in the console, but the behavior persists:
ublock turns off.

Ublock works like a charm under my firefox-esr (68.6.0esr-1~deb10u1) package.
