Firefox 86.0.1 and ublock

After Firefox 86.0.1 updated ublock stopped working on private browsing. It works on opening up as a normal browser. I uninstalled 86.0.1 and rolled back to 86.0 and now private browsing is not blocking ads. Again it is working on normal browser.

I have set firefox to default to opening in private browsing mode and the breaking of ad blockers is not very helpful.

I would like to know how to fix the issue.

Best Regards,

Ramkumar

When you open add-ons, the usual pane to open is labelled 'Extensions' in the left panel. The uBlock add-on should appear as shown in this screenshot. The purple icon shows that the add-on can be used in private windows. If it doesn't, click on the add-on name, stay in 'Details' and scroll down until you see "Run in Private Windows" then select 'Allow'.

Check if uBlock is allowed to work in the private mode.

Extensions in Private Browsing.

I looked at the manage add-ons and there is no check box for running in private window.
