Why do i sometimes get Threat Alerts when first time opening Browser after boot? well today i got 2 i closed browser for spysbot update launched & again, myanimelist.net was already opened but second alert came 1sec after i made new tab so it source may have been myanimelist.net or new tab?

i scanned firefox folder in the direction what is show in the pictures & nothing found, my questions are is there something in myanimelist.net that triggers it or new tab? & should i be worried about it like its just a URL that has been written in some file in firefox folder & i just need to del the entry (ofc that is impossible for some1 like me, finding malicious stuff is even easier then this)? i hope its not big deal that i can leave it be/ignore it, or is it false positive? WTH is going on???

i also want to ask does this alert that it shows firefox exe mean firefox exe was protected/saved from infection or why does it show the exe?

You may have something in your browser that try to connect to that URL

but thing is it happens sometimes times when i open browser after boot, so not awry day & usually after loading myanimelist.net or new tab at least that's how it seems & rest of the day nothing unless that sometimes happens when i watch videos i click play but play also opens new tab & sometimes new window & that site gives similar alert just different URL

malwarebytes i had & removed cause it forced trial version on me when i updated it

one question is it urgent or i can ignore it for new cause Avast is blocking the connection (when it tries to connect again) so it means it should be safe? that i can deal with this when some more issues bile up

so there is no risk? that message means its safe it just alerts that there is something my browser is trying to connect to that isn't safe & it was blocked?

thx for advice & instructions :)

one question more but is it possible that this ver of miner is like loose on the web trying to attack awry browser that connects to the site where it is (at least once when connection to that site first time where it is at)?

i figured out by chance why new tab cause it cause i went to a new site & it also cause same message later it was history & showed on new tab like u see in this picture
so cause it was saved there it gave me alert second time (so it saved the link or how to say it to the new tab page with the miner), but new i can go back to that site without new alert tha's why i ask is it possible it attacks automatically when u access a site where it is hiding, that's just a question

Just a remark,

I like to block all mining in my browser as I do not know what I gain from it,
and I do know that it is detrimental to my computer.

uBlock Origin and/or Antiminer blocks all JS miners on the websites you visit.

Mining will shorten your computer's lifetime. It is bad for your hardware.

If you want to mine, you need specific special crafted computers in specific settings,
but you will have to do it on your own accord on your own computer systems.

Use NoScript, a limited user account and a virtual machine and be safe(r)!

that message i get said it was blocked so avast blocked it

i have u block origin but i think why it sometimes fail is that firefox isn't able to load all the adds i have 4 fast enough sometimes, is it possible? & result avast had to block it
or i need to do something in u blocker settings for that? this massage ofc doesn't happen awry day sometimes its months without any avast threat alerts inducing this
