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

Hi thanhminh.mr!
I was not able to reproduce this issue on latest Nightly version 98.0a1 (2022-01-26)(64-bit) on Ubuntu 20.04. I'll attach the evidence in a file.
Could you please try to reproduce it on latest Nightly and tell us your input? You can download it from here: https://nightly.mozilla.org/
Thanks

Based on your video, I think you are using the built-in Vietnamese keyboard layout.
I (and I think most Vietnamese) instead use this (or something similar): https://github.com/BambooEngine/ibus-bamboo

I was able to replicate this on Ubuntu 20
using firefox release 96.0.3 , Beta97 and Nightly 98

steps:

1. installed this in terminal
   sudo add-apt-repository ppa:bamboo-engine/ibus-bamboo
   sudo apt-get update
   sudo apt-get install ibus ibus-bamboo --install-recommends
   ibus restart

2. Added Vietnamese to Ubuntu language options

3. Added Vietnamese (Bamboo) to Keyboard language options in ubuntu

4. Then i searched for something in urlbar, and search suggestions appeared.

5. Pressed SUPER+spacebar ( and it changed to vietnamese)

6. Typed something in urlbar, for example "microsoft" and no suggestions appeared.

sometimes suggestions did not appear, sometimes appeared after many seconds, and sometimes if you press "microsoft [hit spacebar]" they appear right away.

i will set this as S3 for now.

If you open about:config and set the browser.urlbar.keepPanelOpenDuringImeComposition preference to true, does that fix it?

Yes it does.

More information, I already updated my Firefox to version 97.0 before I tested this.
As the bug is kinda resolved, I have a few question about this setting.
Will this setting be defaulted to true in the future updates?
Will set it to true introduces problems for other users that doesn't use this keyboard specifically?

There are several related bugs, and maybe this should be marked as a duplicate of one of them, but for now I'll add a couple of see-also's. See these bugs and the bugs linked from them:

• Bug 1673971
• Bug 1680801

(In reply to thanhminh.mr from comment #11)

Will this setting be defaulted to true in the future updates?

There are no plans to do that right now, and bug 1680801 is for finding a good way to handle this.

Will set it to true introduces problems for other users that doesn't use this keyboard specifically?

My understanding is this comment from Marco applies in that case (bug 1680801 comment 0):

We could just ignore the problem and show the IME picker on top of the urlbar panel, it is not nice and it is not usable, but also doesn't hurt and avoids the panel flashing on and off.

So it shouldn't cause actual problems, but it may not be a nice UX.

We should create a more understandable description of the keepPanelOpenDuringImeComposition preference for non-technical users, and move the option from Nightly experiments to the Search preferences pane. Adding some examples like Korean and Vietnamese may be worth it.
