1986295 - After returning from Images to All on DuckDuckGo, the address bar shows the URL instead of the persisted search terms and engine chip

Status: NEW

(Firefox :: Address Bar, defect, P3)

Description

[buglinking]

Attachment: ScreenRecording1.mov

Found in

• 142.0.1 (aarch64)

Tested platforms: MacOS 15.3.2 (24D81), Ubuntu:22.04

Preconditions

• browser.urlbar.showSearchTerms.featureGate set to TRUE (default in Nightly)

Steps to reproduce

1. Open a new tab
2. Enter @duckduckgo and press Tab to enter DuckDuckGo search mode
3. Type "ubuntu 22.04" and press Enter to search
4. Click the Images tab (address bar correctly shows full URL with no chip)
5. Press Back to return to All

Expected result
*On the main results page (All), the address bar should again display the persisted search terms ("ubuntu 22.04") along with the DuckDuckGo engine chip.

Actual result

• On the main results page after pressing Back, the address bar displays the full DuckDuckGo URL (e.g., duckduckgo.com/?...&ia=web) and shows no engine chip; the search terms are not
  persisted.

Regression range

• From 1921092

Additional Notes

• As shown in ScreenRecording2, if with default @google, after Step 5, it will rightly display the persisted search terms ("ubuntu 22.04") along with the Google engine chip.
