Description

Steps to reproduce

  1. Open the app
  2. Go to Settings and set New Tab to Blank Page
  3. Create a new tab
  4. Either:

#* Pull to refresh the blank page, or #* Force close the app and reopen it

Actual Result:

  • A grey horizontal scroll bar appears
  • The URL bar is hidden

Expected Result:

  • Either nothing should happen, or we should remove pull-to-refresh from the blank page
  • The URL bar should always be present on this screen

Notes

  • If the issue doesn’t reproduce right away, try restarting Firefox after setting the New Tab to Blank Page, then repeat the steps.

Device & build information

  • Device: iPhone 15 + (18.2)
  • Build version: v139 (55702)

Research direction
Reproduce the bug on a simulator or device by setting new tab to blank page and pulling to refresh. Investigate the pull to refresh gesture handling for blank pages and check if the URL bar is being hidden. Look at the code that manages the loading bar and URL bar visibility during refresh.
