User Agent: Mozilla/5.0 (Windows NT 10.0; rv:52.0) Gecko/20100101 Firefox/52.0 Build ID: 20170323105023 Steps to reproduce: install some addons try to access settings (addon page/klick on addon) Actual results: again no settings available on some addons (µblock, self-destructing cookies and most likley others) that has been the case some time ago. But it was fixd and now its here again... appears on a new FF installaton on a (fresh android 6.01) sony z3c android 6.01 device and also on an old sony xperia M.

Thanks, unfortunately the search didn´t find any existing bugs regarding my keywords so that means I have to wait until 53 comes out if I want to use these addons...

Any unforeseen issue notwithstanding, that'll be next week, though. In the meantime, at least for restartless add-ons a possible workaround is to de- and re-activate the add-on from within the add-ons page within the add-on manager.

de- and re-activate the add-on doesn´t work for the above mentioned add-ons. But at least I´ve found µblock settings in the FF menu (3 vertical points in upper right side)

Hi I can access all add-on settings now. But if an add-on is disabled and I enable it again, the settings will only appear if I press the Back-Button and then tab on an add-on again. Its not a big problem. But settings should appear immediately when activating an add-on.
