Here a list of some issues with firefox add-ons and the way to fix it:

Firefox ESR 52.x and uBlock 1.15:
- Ctrl+G shortcut doesn't work anymore
  - set ublock to Off or wiki site in ublock whitelist
Firefox ESR 52.x and uBlock 1.15:
- edit a page in WYSIWYG mode/deploy breadcrumb tree/click on a page of treeview: URL in FF adress bar is correct but the target page is not displayed
  - set ublock to Off is not enough then ublock must be deactivated.
