User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:69.0) Gecko/20100101 Firefox/69.0
Steps to reproduce:
A little background;
I am using Firefox on my laptop along with Chrome and Windows Edge. My laptop has 8 GB RAM with powerful CPU.
I normally use all 3 browsers at the same time
Actual results:
When I open too many tabs on Firefox, it slows down and says something is slowing down your system and give me two options. I choose to close its thread. Sometimes it works and kill slow thread, sometime not.
Expected results:
In short, when I open many tabs, Firefox either freezes or slows down in a way that I can not use it. I suspect the following would be issue:
1- too many cookies or plugin installed?
2- Other web browsers are running on my Widows 10 at the same time?
3- There might be a clash among installed plugin
4- it might be a bug
Also, I do not like third-party plugin and I do not install them. So can they install themselves without my consent...
Best,
Matt

Hi Matt,
Thanks for submitting this bug to us. I've tried to reproduce it using Firefox 71.0a1 (2019-10-07) (64-bit) and Firefox 69.0.2 (64-bit) and I wasn't able to reproduce it
I've opened up 342 tabs (wikipedia, amazon, youtube) and everything worked fine.
Does this issue occur with a fresh profile? You can find the steps here: https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles?redirectlocale=en-US&redirectslug=Managing-profiles#w_starting-the-profile-manager
Can you please download Firefox Nightly from here: https://nightly.mozilla.org/ and retest the problem and see if the issue still occurs there as well?
If after doing this you can still reproduce the bug, could you send me a screenshot or a video of the bug? That always helps a lot.
Thanks!
Sebastian

Hi Matt,
I'm marking this as Resolved-Incomplete due to lack of response. If the issue is still reproducible with the latest Firefox version, feel free to reopen the bug with more information.
Thanks!
Sebastian
