Prerequisites

  • Your issue may already be reported.
• This is not a support issue or a question
  • Support issues and questions are handled at /r/uMatrix
• I tried to reproduce the issue when...
  • uMatrix is the only extension
  • uMatrix with default lists/settings
  • using a new, unmodified browser profile
• I am running the latest version of uMatrix
• I checked the documentation to understand that the issue I report is not a normal behavior

Description

Links with multiple redirects in Firefox stop working on the second redirect. Clicking the uMatrix reload button will not allow the browser to move on to the next redirected page. User must close the tab and reopen, then temporarily allow domain again before reloading.
