Bug: when starting a download request, the motrix download manager does not receive it and the browser's download manager is used instead
Debug
When going to firefox's debug page of extensions, the following message about motrix-webextension was present:
Reading manifest: Warning processing permissions: Error processing permissions.1: Value "downloads.shelf" must either: must either [must either [be one of ["idle"], be one of ["menus.overrideContext"], be one of ["search"], be one of ["activeTab"], be one of ["cookies"], be one of ["scripting"], or be one of ["webRequest", "webRequestBlocking", "webRequestFilterResponse", "webRequestFilterResponse.serviceWorkerScript"]], must either [be one of ["mozillaAddons"], be one of ["normandyAddonStudy"], be one of ["urlbar"], be one of ["activityLog"], be one of ["networkStatus"], or be one of ["telemetry"]], be one of ["alarms", "storage", "unlimitedStorage"], be one of ["captivePortal"], be one of ["identity"], be one of ["menus", "contextMenus"], be one of ["geckoProfiler"], be one of ["contextualIdentities"], be one of ["declarativeNetRequestWithHostAccess"], be one of ["dns"], or be one of ["theme"]], must either [must either [be one of ["idle"], be one of ["menus.overrideContext"], be one of ["search"], be one of ["activeTab"], be one of ["cookies"], be one of ["scripting"], or be one of ["webRequest", "webRequestBlocking", "webRequestFilterResponse", "webRequestFilterResponse.serviceWorkerScript"]], be one of ["clipboardRead", "clipboardWrite", "geolocation", "notifications"], be one of ["bookmarks"], be one of ["browsingData"], be one of ["devtools"], be one of ["find"], be one of ["history"], be one of ["pkcs11"], be one of ["sessions"], be one of ["tabs", "tabHide"], be one of ["topSites"], be one of ["browserSettings"], be one of ["declarativeNetRequestFeedback"], be one of ["downloads", "downloads.open"], be one of ["management"], be one of ["privacy"], be one of ["proxy"], be one of ["nativeMessaging"], or be one of ["webNavigation"]], be one of ["declarativeNetRequest"], or match the pattern /^experiments(.\w+)+$/
Partial Solution
I downloaded the repo and changed the manifest, removing this "downloads.shelf" permission and built the project with yarn and tested the extension again, then a second error message in the debug session of firefox appeared: the same as above but with the permission "offscreen".
Then, I did the same as above: removed this permission from the manifest and built again. After adding this new version to my browser, adding the secret key and restarting my browser, the extension worked correctly and I was able to download files with motrix automatically.
A attempt of a actual fix that did not work
Then, I tried to come up with a manifest.json that did not use these 2 permissions on firefox but does not remove then from the chrome version. I tried to do this with the browser_specific_settings json key in the manifest by adding a different permissions key in there but it did not work. The firefox browser reported the extension as being corrupt.
