Ako tijekom pokretanja web-preglednika Mozilla Firefox u ^{(Mozilla Firefox)}Windows 10/8.1 dobijete poruku o pogrešci Couldn't load XPCOM , svaki put kada ga pokrenete, evo nekoliko stvari koje biste mogli pokušati riješiti i riješiti problem.

Firefox nije mogao učitati XPCOM

XPCOM je multi-platformski komponentni objektni model, koji je sličan Microsoft COM -u, a potreban je za upravljanje datotekama i memorijom, osnovne strukture podataka i tako dalje.

Ova pogreška pri pokretanju Firefoxa obično se može pojaviti nakon vraćanja ^(Firefox)sustava Windows^{(Windows System Restore)} ili ako je pokrenete u Sandboxu^(Sandbox) . Zapravo, i ja sam primio ovu poruku prije nekoliko dana nakon što sam nekoliko puta dao da sustav vrati svoje računalo kako bih riješio neke druge probleme.

1] Pokrenite u sigurnom načinu rada i pogledajte

Otvorite izbornik Firefoxa^{(Firefox Menu)} , kliknite gumb " Pomoć^(Help) " i odaberite Ponovo pokreni s onemogućenim dodacima^{(Restart with addons disabled)} . Ako ovo riješi vaš problem, možda ćete morati onemogućiti neki dodatak koji uzrokuje probleme.

2] Napravite novi Firefox profil

Izradite novi Firefox profil^{(Create a new Firefox profile)} i provjerite hoće li zbog toga problem nestati.

3] Resetirajte Firefox

Resetirajte Firefox i provjerite hoće li vam to pomoći.

4] Deinstalirajte i ponovno instalirajte Firefox

Ako ništa ne pomogne, možda ćete morati svježe instalirati Firefox^{(fresh-install Firefox)} .

Sigurnosno kopirajte svoje oznake i spremljene lozinke na sigurno mjesto. Deinstalirajte Firefox . Odaberite opciju Ukloni^(Remove) moje osobne podatke i prilagodbe Firefoxa . ^(Firefox)Imajte^(Remember) na umu da će se kada to učinite sve mape profila ukloniti i da ćete izgubiti osobne podatke kao što su oznake i lozinke. Stoga^(Hence) sam rekao - prvo ih poduprite.

Provjerite mapu Program Files . Izbrišite C^{(Delete C)} :\Program files\Mozilla Firefox ili C:\ Program Files (x86)\Mozilla Firefox , ovisno o vašem slučaju.

Također izbrišite sljedeće mape ako ih vidite na računalu. Mape mogu biti skrivene i možda ćete ih morati otkriti putem opcije mape^{(Folder Option)} :

• C:\Users\username\AppData\Local\Mozilla\Firefox
• C:\Users\username\AppData\Local\Mozilla\updates
• C:\Users\username\AppData\Local\VirtualStore\Program Files\Mozilla Firefox

Upotrijebite siguran čistač registra kao što je besplatni CCleaner za brisanje smeća na računalu i za čišćenje Windows Registry od preostalih unosa u Firefoxu .^(Firefox)

Ponovno pokrenite svoje Windows računalo i ponovno instalirajte Firefox nakon preuzimanja s njegove službene web stranice.

I opet – jednostavno instaliranje najnovije verzije Firefoxa preko postojeće instalacije također može pomoći. Upalilo je barem meni.^{(Then again – simply installing the latest Firefox version over your existing installation can also help. It worked for me at least.)}

Želite li i ove pogledati?^{(Want to have a look at these too?)}

1. Mozilla Firefox nastavlja usporavati na Windowsima^{(Mozilla Firefox keeps slowing down on Windows)}
2. Vratite izbrisane oznake Firefoxa^{(Restore Deleted Firefox Bookmarks)}
3. Vaša veza nije sigurna u Firefoxu
4. Firefox zamrzavanje ili rušenje u sustavu Windows^{(Firefox Freezing or Crashing on Windows)} .

Firefox couldn't load XPCOM in Windows 11/10

If when running yoυr Mozilla Firefox web browser on Windows 10/8.1, you receive a Couldn’t load XPCOM error message, every time you run it, here are a few things you may want to try to troubleshoot and fix the issue.

Firefox couldn’t load XPCOM

XPCOM is a cross-platform component object model, which is similar to Microsoft COM, and is required for file and memory management, basic data structures and so on.

This Firefox start-up error can typically occur after performing a Windows System Restore or if you run it in a Sandbox. In fact I too received this message a few days back after I had the system restore my computer a couple of times to fix some other issues.

1] Start in Safe Mode and see

Open Firefox Menu, click the “?” Help button and select Restart with addons disabled. If this solves your issue, you may need to disable some problem-causing addon.

2] Create a new Firefox profile

Create a new Firefox profile and see if that makes the problem go away.

3] Reset Firefox

Reset Firefox and see if that helps you.

4] Uninstall and reinstall Firefox

If nothing helps, you may have to fresh-install Firefox.

Back up your bookmarks and saved passwords to a safe location. Uninstall Firefox. Select the Remove my Firefox personal data and customizations option. Remember that when you do this, all profile folders will be removed and you will lose personal data like bookmarks and passwords. Hence I said – back them up first.

Check the Program Files folder. Delete C:\Program files\Mozilla Firefox or C:\Program Files (x86)\Mozilla Firefox, as your case may be.

Also delete the following folders if you see them on your computer. The may be hidden folders and you may have to unhide them via Folder Option:

• C:\Users\username\AppData\Local\Mozilla\Firefox
• C:\Users\username\AppData\Local\Mozilla\updates
• C:\Users\username\AppData\Local\VirtualStore\Program Files\Mozilla Firefox

Use a safe registry cleaner like freeware CCleaner to clear PC junk and to clean the Windows Registry of residual Firefox entries.

Restart your Windows computer and fresh-install Firefox, after downloading it from its official website.

Then again – simply installing the latest Firefox version over your existing installation can also help. It worked for me at least.
