brave-browser: regression: external extensions are forcefully disabled on Linux since 0.68.131
Description
On Linux it is possible to install extensions using a preferences json file as per docs.
This is used for distributing extensions as distro packages.
This is not working anymore in Brave 0.68.131, I do see the extension in brave://extensions but it gets disabled on browser startup with the following popup:

This works correctly in previous versions (e.g. Brave 0.67.125) and in latest Chromium (76.0.3809.100).
Steps to Reproduce
On Linux:
- Put for example the following file in
/usr/lib/browserpass-chromium/browserpass-chromium-3.1.1.crx - Create file
/usr/share/chromium/extensions/pjmbgaakjkbhpopmakjoedenlfdmcdgm.jsonwith the following contents:
{
"external_crx": "/usr/lib/browserpass-chromium/browserpass-chromium-3.1.1.crx",
"external_version": "3.1.1"
}
- Launch Brave
Actual result:
Extension is present on brave://extensions but is disabled on startup
Expected result:
Extension is not disabled
Reproduces how often:

Miscellaneous Information:
I’ve seen https://github.com/brave/brave-browser/issues/2457 and https://github.com/brave/brave-browser/issues/5063 but I don’t think it’s duplicate, because this clearly worked in the previous release version of Brave 0.67.125

@rebron @bsclifton Could someone be assigned to this? Brave is basically useless due to this regression
This is a terrible design decision and deal breaker for using Brave. It damages trust in the marketing on brave.com:
Where is the power and control?
This should officially be fixed now with https://github.com/brave/brave-core/pull/8392 😄
I duplicated this issue (didn’t find on initial search) by creating https://github.com/brave/brave-browser/issues/15024. I’ll link to here from that issue and I captured proper test steps in the pull request
The fix for this issue will be in the next Nightly build (1.25.x) and it will propagate through the channels (Beta in 3 weeks, then Release 3 weeks after that). It should hit Release channel on 25 May (2021)
Thanks for your patience folks! We had an unintentional deviation from Chrome/Chromium and I put tests in place to make sure this doesn’t regress
@kakolisgay A bit late, but please see my comment here:

From the Brave Website:
This behavior seems intentional to me, maybe @fmarier can provide more information.
If someone is able to identify a deviation from Chrome which is causing this to break in Brave but not in Chrome, I would not assume that it is intentional. It is more likely to be accidental.
@rushilsrivastava Source? If this is something that brave has deliberately done I’m fine completely dropping it in favour of other alternative browsers
No, I already have that enabled
Also getting this problem. Effects several extensions I’ve been working on, due to this I’m effectively locked out from developing them. This issue effects all non-store extensions, even ones I’ve signed and published myself

@fmarier The issue stems from
ExtensionService::CheckManagementPolicy()andInstallVerifier::MustRemainDisabledwhich eventually get angered at something the chromium kernel has found wrong with a system. The same issue has been reported to happen on old versions of chrome so I assume brave has broken or changed something that was preventing this from happening in a normal installationSeems whatever setting is causing this behaviour is not profile-specific. I’ll be looking through chromiums database files and I’ll post back if I find whatever’s causing this
@bsclifton No
