Can you enter about:profiles in the URL bar, create a new profile and test it again in this new profile?

I have already created 100 profiles, and the bug will continue to appear for many years on all computers in the world with windows 7. I have tested this error on many computers of my friends.

tabbrowser.js = bug!

This component causes memory leaks and blocks all basic Firefox functions and blocks many extensions from working.

Firefox adress: chrome://browser/content/tabbrowser.js https://pastebin.com/wjrUy2qA

Problem /issue, memory leak , block function, crash Line: 2204

 return (browser._cachedCurrentURI = Services.io.newURI(url));
