When Firefox is loaded and a URL is being accessed, network latency peaks so high that ping requests timeout and internet traffic stops or is so slow that applications are unusable.

firefox latency -1.JPG
User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:132.0) Gecko/20100101 Firefox/132.0
Steps to reproduce:
Load firefox and access a URL. This reproduces the problem every time.
This happens when Firefox is in troubleshooting mode also.
Actual results:
- Pings go from >60ms to < 3,500ms and then times out.
- All internet traffic slows then stops.
- Other applications that use the internet are unusable.
Expected results:
Loading Firefox should have negligible effects on latency and internet access.
See text file 'Firefox cause high latency.txt' for details of troubleshooting and related image file.
stopped cisco.com loading. Firefox is idle and latency decreases, ping responses are low, internet traffic resumes.
Reloaded cisco.com Latency increases until pings time out and internet traffic stops.
Quit firefox - Latency decreases, ping responses are low, internet traffic resumes.

Started firefox and went to cisco.com. Latency increases until pings time out and internet traffic stops.
This issue isn't with just cisco.com. It's with just about any URL I try to access. Sometimes I can use Firefox for 20-30 minutes before the latency problem occurs. Other times it's right away.

I will create a new profile and see if the problem reoccurs - and report my findings here.- Does this issue happen in the latest nightly? Here is a link from where you can download it: https://www.mozilla.org/en-US/firefox/channel/desktop/
I will install the latest nightly as you suggest and report back.- Do you have any addons installed? If yes could you please list them?
I have these addons, but disabled them all by restarting Firefox in Troubleshoot Mode. All the testing I have done so far was in Troubleshooting Mode with the addons disabled.- Could you please provide more detailed steps on how to reproduce the issue or provide a screen record with the issue?
I have provided a text file that details my steps along with screenshots #1 to #5. Do you need more screenshots and details?
Give me a day to create a new profile and install the latest nightly.
Thank you.

Well darn. Just like taking a car with obvious engine trouble to a mechanic for repairs - and the symptoms can not be duplicated - the same with this issue. Since filing this bug report, I can not reproduce the problem.
I have done as Negritas Sergiu suggested and started Firefox with a new profile and the problem does not occur. Even using my main profile for the last three days the problem of high latency and loss of internet activity does has not reoccurred.
Therefore, I am resolving this as Invalid.
Thanks.
