For whatever reason, today Opera suddenly started blacklisting (and thus blocking) the "Tampermonkey" extension I have installed, claiming that is was identified as being "malicious". Since both the Opera Addons Store and the Chrome Web Store still happily list and offer the extension, I suppose that this is due to an error (= false positive)?
Unfortunately, I haven't found an obvious way to re-enable the extension and override the blacklist. How do I do this?

Technical details:
Platform: Windows 32bit
Opera Version: 57.0.3098.110
Steps to reproduce:
Try to install Tampermonkey (Version 4.7.54) from the Chrome Web Store (https://chrome.google.com/webstore/detail/tampermonkey/dhdgffkkebhmkfjojejmpbldmpobfkfo)

Thanks for the hint!

I was referring to the version listed in Google's webstore (https://chrome.google.com/webstore/detail/tampermonkey/dhdgffkkebhmkfjojejmpbldmpobfkfo) which I was using before and which is still blacklisted for whatever reason. I would prefer to stay with that version, which got updated much more frequently in the past. As I wrote before--every other Chromium-based browser allows it. I cannot see what makes it so especially "malicious" when used with Opera.

I've been using that version in Vivaldi since Opera started blacklisting Tampermonkey (actually, I only used Vivaldi since that day) and haven't noticed any negative impact. Maybe I'll just keep using Vivaldi, it has all the features Opera has. It only feels a little less responsive than Opera does in my everyday use.

The fact that the extension is still listed in Chrome's Web Store and isn't blocked in Vivaldi (and other Chromium-derived browsers using the Chrome Web Store) either makes me think that blacklisting Tampermonkey simply is a bug, unless Opera knows more than anybody else on the planet.

If you want to use Tampermonkey from the Chrome extension store, there's no sense in wasting time with Opera. It just won't work. Even if you follow the instructions correctly and Tampermonkey is temporarily unblocked, Opera will decide for you that this isn't good and re-block it some hours later. And since they have successfully been ignoring this support request for the last 5 years, I would not expect anything new. I can understand that--deleting Tampermonkey's ID from the list of blocked extension would literally mean 30 seconds of work, and no one can really ask for that much commitment.
Just use another decent Chromium-based browser. I would suggest Vivaldi (https://vivaldi.com), which is at least as versatile as Opera.

It's now almost two weeks that Opera has been blocking the Tampermonkey extension for some theoretical risk of abuse, while every other Chromium-based browser I've tried (Vivaldi, Chrome, Chromium, Yandex, Dragon, Iron) is happily allowing its use, and the world is still turning.

Moreover, the developer has published an update to the extension on 2019/1/6 already that should invalidate any attempts to sneakily foist the extension itself or malicious userscripts on unsuspecting users, because now not only a 3rd party installation of the extension has to be explicitly approved by the user, but also a userscript not installed from within the browser is deactivated by default unless specifically allowed.

When is the extension going to be unblocked by Opera?

I asked for a function to more closely control update behaviour just 3 days ago (Feb 24). My post was moved to the suggestion box. (Well, technically that's right, because I suggested a new function.

Maybe everyone reading here who's also interested in controlling Opera's update behaviour could add to my thread, so it doesn't appear as if it's just me.

Dear people,

is it possible to change the update mode of "new" Opera - preferably to something like "notify only" instead of silent background updates? I'm sitting on a slow line at home so that I'd prefer to just be notified that a new version is available - I can then download an offline package at work.
The only "option" I've found so far is disabling updates altogether by jumping through hoops like setting system variables, disabling scheduled tasks (and hoping that I haven't overlooked something else and Opera silently starts downloading updates again anyway );<

The easiest (for the user way would certainly be a simple setting ("no autoupdating", "notify before download", "notify before installation", "update silently" - the way Firefox or eg. Adobe Reader offers it), but even such an unnecessarily complicated solution like Google offers it for their updater (group policies) would still be better than the present situation IMHO...

Thanks a lot!
