[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Firefox::Address Bar' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Can you provide a screenshot in the situation where you are not receiving suggestions but expecting them? And what is your default search engine set to?

Thanks

Hello! I have tried to reproduce the issue with firefox 149.0a1(2026-01-19) on Ubuntu 22.04 and Windows 10 , unfortunately I wasn't able to reproduce the issue.
Could you please answer the following questions in order to further investigate this issue

1. Does this issue happen with a new profile? Here is a link on how to create one: https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles
2. Could you please provide a video with the issue?

Could you please answering the question in comment 2, and also tell us which Search Engine you have set as default? Thank you.

Hello,

(I can't attach screenshot, neither video ; I didn't find here any menu/button to do that)

I created a new (blank) profile.
I setup up search suggestions in the preferences dialog.
I try to search for bookmarks, since there is no history.
I displayed the default bookmarks (Ctrl-b).
I tried to search for one of the bookmarks in the address bar.
No result.
No suggestion as I type.

I'd emphasis on the fact that it worked well until recently.
Typing in address bar would give me instant results for history, bookmarks, tabs and google search.

Regards

Hello,
here is the log copied from about:support.

Comment 12

[Marco Bonardo [:mak]]

This is pretty strange, it looks like the results pane is not being shown at all.
There is no UserChrome (good), and main preferences look sane, afaict.
I wonder if it's some kind of issue specific to KDE or the specific distribution.

I'll ask you some additional question, sorry about that, but this needs a bit more info:

1. if you go to about:config and set browser.urlbar.keepPanelOpenDuringImeComposition to true does it make any difference?
2. if you open the Browser Console from main menu / Other Tools, when you type in the urlbar do you see new Errors being listed? If so could you please post them here?
3. This was not installed through Flatpak or Snap, right?

Comment 13

[michel briand]

Hello, thanks for your answer.

Yes, I use KDE.

This is firefox packaged by Debian (trixie + security) :

firefox-esr
140.7.0esr-1~deb13u1
amd64

1. I've set browser.urlbar.keepPanelOpenDuringImeComposition to true, but no change.
2. Ok. It does not say much more. Log attached in next post.
3. Debian

I tried to log out and log in in Cinnamon desktop. But no change : same behaviour for Firefox.

Comment 15

[Moritz Beier [:mbeier]]

Could you try enabling troubleshoot mode to check if the issue persists?

Comment 16

[Marco Bonardo [:mak]]

see comment 15.
if troubleshoot mode helps, it may be hardware acceleration, or an unexpected add-on conflict.
if troubleshoot mode doesn't help instead, you could also try launching from the console with MOZ_ENABLE_WAYLAND=0 firefox to force X emulation.

Comment 17

[michel briand]

Hello,
I tried troubleshoot mode.
No change.
I tried to remove all packages installed (apt purge firefox-esr-*) and to reinstall it.
No change.
:(

Comment 18

[Marco Bonardo [:mak]]

can you please try launching firefox binary with the MOZ_ENABLE_WAYLAND=0 ENV variable set?

Comment 19

[michel briand]

Yes, I do.
No change :(

Comment 20

[Mark Banner (:standard8)]

Emilio, any ideas if we've heard about this before, we've already tried the normal troubleshooting? This is happening on ESR 140. Is there a simple way the user could determine what's happening with the pop-up?

Comment 21

[Emilio Cobos Álvarez [:emilio]]

Not really...

I'd emphasis on the fact that it worked well until recently.
Typing in address bar would give me instant results for history, bookmarks, tabs and google search.

Hmm, if this works on a blank profile and doesn't anymore, could you try mozregression to try to see when it broke for you?

Comment 22

[michel briand]

I'd guess it is not related to profile:

• I logged in as a distinct Linux user and setup search suggestions on
• I tried a search in address bar: no popup, no suggestion
• I tried this procedure with my distinct user and 2 different desktop environments: Plasma X11 and XFCE X11

Comment 23

[michel briand]

I just opened my eyes :) ! In Plasma "start" menu, search feature returns, amongst main menu results, several firefox results:

• opened firefox windows
• opened firefox tabs
• navigation history of firefox
  I have installed (or so it has been installed by plasma) the "Plasma Integration" extension (version 2.0, 2025-10-24).
  Is there a possibility that this extension could interfere with address bar search feature ?

Comment 24

[Marco Bonardo [:mak]]

I think that's nsGNOMEShellSearchProvider, it shouldn't interfere with the address bar, it uses its own search capabilities.
plus when you tested in troubleshoot mode, that disables all the add-on temporarily.

I think mozregression, as suggested in comment 21, is the best bet to figure out something here.

Comment 25

[michel briand]

My test is to create a new tab and type in address bar (something that I know to be in history/bookmarks).
If nothing happen, then the test fails.
If a popup with some search result appears, then the test succeeds.

Using mozregression, my tests show:

• system version (debian trixie 140.7.0esr-1~deb13u1) : FAILS
• mozilla-central build for 2024-06-10, application_version: 129.0a1 : SUCCEEDS
• mozilla-central build for 2025-05-26, application_version: 141.0a1 : SUCCEEDS

Comment 26

[Mark Banner (:standard8)]

Please could you try downloading a build from here and see if that works for you? I'm wondering if there might be an issue with the system version that you are using.

Comment 27

[michel briand]

Hello,
I downloaded and tried the build 140.7.1 for Linux x86_64.
The url bar / address bar search is WORKING :) !
I'll submit a bug to Debian.
