Hi, an suspicious addon appeared few weeks ago in my Firefox. It's called "My Popup Blocker" and Avast! (antivirus software) marks it as suspicious or unwanted. Firefox automatically disabled it after a while, but it is not possible to remove it. I tryed to delete it via Avast! but addon appeares again after a while. I tried to reinstall Firefox, but addon is still there. This addon appeared after I installed aTube catcher (I uninstalled it already). Could it be malware? Thank you.

Chosen solution

Zkus ještě ve složce s profilem otevřít v texťáku soubor prefs.js a vyhledat řádky začínající user_pref("extensions.webextensions.

Podle toho, co jsem našel, tak ten My Popup Blocker není na stránkách doplňků Firefoxu, ale instaluje se do počítače někam do Program Files, asi takto: C:\Program Files (x86)\mypopupblocker\ff\my_popup_blocker-1.0.0-fx.xpi Zkusil jsi ho odinstalovat?

I found this: https://bugzilla.mozilla.org/show_bug.cgi?id=1602821

It seems that addon was blocked because of "collecting ancillary information: URL, tab id, hostname, title, version". Ok it's blocked, but why is it still in my Firefox Addon manager?

Přes ty tři tečky (na obrázku) to odebrat nejde? My Popup Blocker 1.0.0 ({7bb202fa-9247-49c6-898c-ce0d36bc44e3}) (Neaktivní) Ve složce s profilem - Extensions si podle toho čísla v lomené závorce najdi ten doplněk a smaž ho (nejlíp při ukončeném Firefoxu).

Obojí jsem zkoušel a najde to. Ve složce extensions vůbec není.

Tak nevím, ale já ho tam v seznamu vidím.

Ano, já ho tam taky vidím. Ale v profilu, ve složče Extensions doplňek s tímto ID není.

Jo byl tam! Vůbec mě nenapadlo, že by se doplněk instaloval klasicky do Program Files. Odinstaloval jsem jej a zbytek složky smazal a je pryč. Otázka je jak se vůbec do počítače dostal, resp. s čím se nainstaloval, viděl bych to na ten aTube catcher. Každopádně ti moc děkuju za pomoc! Vyřešeno.
