Laggy Navigation Bar on Pixel 5a
Problem occurs immediately upon opening the navigation bar - the keyboard takes a few seconds to appear and input does not appear immediately in the bar. This occurs with both Gboard and SwiftKey. Keyboard display is also laggy, with the highlighted keys taking time to revert to standard appearance.
Changing the search engine (tested Bing, DuckDuckGo, and Wikipedia) and disabling all suggestions/alternate input methods does not seem to affect behavior, lag is still present. Autocorrect suggestions appear with no lag and pressing enter/return immediately attempts to load the autofilled page or search, even if the text is not fully visible in the navigation bar.
Problem is present using Firefox 91.3.1 and Nightly 93.0a1 on Android 11 on a Pixel 5a.
This is a fresh installation of Firefox with no account synced, and I have cleared the cache and storage for the apps after encountering the problem.
Problem does not occur using Firefox Focus 91.3.0. The only search engines on Focus I tested were Google and DuckDuckGo, but I tested with and without search suggestions. Problem also does not occur with Google Chrome.
Happy to help with additional tests and/or videos.

Hi
Would you be able to follow the guide at this page and create a profile for us to look at in more depth?

The problem went away after about a day (over the weekend), no changes to settings were made. I was planning to check whether it was related to my work network today, the problem hasn't returned here either.
I tried making a startup profile regardless, in case the behavior is nonstandard. I will try and remember this process if the lag comes back. https://share.firefox.dev/3t1pcZW
Hi
It may have been the case that something else was happening on the device (such as a number of app updates or actions within apps) which is why you saw it then, but not more recently.
Thank you for that profile. I am going to hold fire on this right now given that you mention that it has not reoccurred, but please come back here and mention it if it happens again.
The navigation bar lag has happened again.
I recorded a log in Nightly, with the following actions:
1. Touch address bar. 2. Type in "test." 3. Hold backspace to delete "test." Waiting ~5 seconds in between tasks.

I rebooted my phone and tried again, this made the lag go away. I repeated the same actions.

It looks like there are large spikes in the AndroidUI category graphs.
If it also helps, I took a log without specific timings and typed more things into the search bar. https://share.firefox.dev/3k4ReRK
