Hi,@pajtaz 
Thank you for posting your issue on our business forum.

You may try the following troubleshooting suggestions:

• Please clear the cache of your Firefox browser and restart the browser afterwards.
• Please update your Firefox browser to the latest available official version.
• Please try accessing your device's management web interface in Firefox's private browsing mode.
• Please make sure no other third-party browser extensions are running in the browser when you open the management page.

If the issue is not resolved, please feel free to leave more information here!

  @Jeremy_12 None of that works. Latest versions, cached cleared, no extensions, private browsing - no matter what, there are missing keystrokes.

I am not sure what other kind of information do you need. I can troubleshoot if you want me to dig deeper why this happens.

Hi,  @pajtaz 

Thank you for your patience.

We are writing to confirm whether you are still experiencing this issue . Should the issue persist, could you please kindly provide us with the version number of your Firefox browser? We will follow up with you via your registered email address.

Thank you for your understanding and cooperation.

I just tested this, it definitely happens!  Seems a bit sporadic though, sometimes its fine

Tested on ER7206 v2 latest beta, 605v2 latest stable, ER8411 latest stable

Firefox 149.0.2, Mac OS 15.7.5, Apple Silicon M3 Air

  @Jeremy_12 It is still happening. It happens on several types of Firefox running on PCs. It does not happen on Firefox on Android. It happens with or without any extensions running.

On Windows 11 Firefox version 149.0.2.

On Linux Debian 13 Firefox version 140.9.0esr.

I have had this same issue on these firmware updates.

Im on 2.3.3 Build 20251029 Rel.18054

I was able to find the cause of the stutter. Under developer tab > Network you can see POSTs for locale?form=lang page accumulating at the exact frequency of the login page stutter (about every 2 seconds.) 1000ish requests over 38 mins...

My experience was this happened in any browser i tried but did NOT occur on the tp link emulator for this model and version login page.

See attached screen shot.

I have noticed this stutter behavior for a while and it does make logging in somewhat difficult. I saw some threads alreadying posting this reported behavior so I replied to a few of them to get some visibility for it.

Thanks,

I am also using up to date firefox with 2.3.3 Build 20251029 Rel.18054 and confirm this behavior. No clearing of cache or use of private windows fixes the probem. This makes logging in a pain. The problem does not manifest with Edge.

I plan to try this firmware soon and note any change.

  @Vincent-TP 

I was able to test this build. I noted the updated UI. I still notice the stutter in multiple broswers, perhaps slightly improved but still present.

Thanks,
