@NA0341 said in Is the »Web Store« Extension needed for Extension Updates?:
The "Add to Chrome/Vivaldi" - Button is gone when I disable it and restart.
Then it works as expected on your system, possibly Windows only issue.
Need more Windows users to confirm this.
As for your original question(s):
Am I right in assuming I don't need the Extension to be enabled in settings for Updates?
AFAIK you don't need the Web Store component to update extensions. But I've never tested this.
Is there a way to disable checking for Extension updates entirely while still having Webstore Extensions installed?
No, checking for updated extensions is mandatory - for security reasons I guess. Google needs a way to disable extensions remotely in case they are removed from the store for security reasons.
If you don't want updated extensions you need to use them unpacked and manually updated (i.e. from a Github repo or similar).
Have installed and disabled Extensions any impact on the browsers performance or stability?
Depends on the extension.
Some reduce up quite a bit of performance.
Some improve performance greatly (adblockers).
Some virtually nothing.
Some are malicious and will try to scam you or might even steal your data.
You want to use extensions? Up to you 🙂
EDIT: Oh you said "disabled" extensions - then the answer is none.
