I just realized that there seems to be a conflict with uBlock Origin as a Firefox add-on and editing self hosted WordPress sites.
When I’m in my dashboard and edit a post or a page and hit view page, the preview does not show up and clicking any link or a button in the menu doesn’t have any effect. I have to reload the page in FF to see the preview and to be able to navigate to any other point in the WordPress installation.
In FF the problem exists since version 1.13.10 - going back to version 1.13.8 or deactivating the add-on “solves” the problem.
I tested with Win 7 Pro, FF 55.0.3 (32 bit) on different machines and with different WordPress installations.
Is there anyone who can reproduce this problem? Any ideas to solve it?
In Chrome uBlock Origin version 1.14.8 just works fine.
