Φόρουμ υποστήριξης - Firefox

Hello, I wanted to restore Firefox to start clean. I wanted anyway to reinstall my (few) extensions, all of which are safe and well known. When I do that, though, their icons don't show up in the toolbar. When I open the "customize toolbar" setting, extension icons aren't there. So there's no way to add them to toolbar.

I tried all possible methods: - "Restore Firefox" and resync my account (extensions are reinstalled but icons not shown in toolbar / customize toolbar) - "Restore Firefox", not syncing, and manually installing extensions (icons still not shown in toolbar / customize toolbar) - Uninstall Firefox, delete everything in Profiles folder, reinstall Firefox. Same behavior.

So, it seems it's something not related to a broken profile, since a fresh profile, with no syncing, does not fix the issue.

Any clue of what I could try? Thanks!

Lately for the last 3ish days my YouTube connection speed on Firefox and only Firefox has been terribly slow. So slow that it can't even watch normal HD content. But not always, sometimes it does work at normal internet speeds which is so weird. I have around 500 Mbps download speed internet so I know it's not the issue. The picture with the slow download speed is on Firefox and the fast/normal download speed is on Chrome. Sometimes in a private window Firefox runs at normal speed but not always, I don't think it's an extension issue.

Hello, Microsoft Defender did a scan tonight and apparently detected a trojan script, located in the folders for Firefox extensions for both profiles I use on my computer

Trojan description: Trojan:Script/Wacatac.B!ml

Files: C:\Users\[user]\AppData\Roaming\Mozilla\Firefox\Profiles\[default profile]\extensions\langpack-fr@firefox.mozilla.org.xpi C:\Users\[user]\AppData\Roaming\Mozilla\Firefox\Profiles\[second profile]\extensions\langpack-fr@firefox.mozilla.org.xpi

This scan happened at 9pm, and a previous scan at 6pm didn't show anything. When it detected the script, MS Defender contained it and apparently deleted it when it asked me to restart the computer, I then did a full offline scan and nothing else showed up, same with a full scan with the free version of Malwarebytes. I didn't do anything unusual between 6pm and 9pm, so I'd like to know if there's a way to determine whether that script was an actual threat (instead of a false alarm)? If so, any way to know how long it has been on my computer? Any further risks to take into consideration? Other steps to follow? Thanks for the help

To resolve an issue that has been plaguing me, I did a clean install of Firefox. I followed some instructions I found on here that ensured that all I had to do was rename the existing Firefox folder to something else, download and run the installer again, and I should have done a clean install without losing my user data.

The issue I had has been fixed, but all of my add-ons and bookmarks are gone. I can get the add-ons back, but where can I find the bookmarks in the old Firefox folder?
