Add-Ons that cause or have caused problems with Duolingo

[severin]

Based on feedback, the following Chrome extensions cause (or caused) problems with Duolingo:

• Ghostery
• Adblock
• DNT

any other ones?

I use Adblock and it works for me, here. However, Ghostery is known to cause problems (on various sites, not just duolingo)

[severin]

another one (obviously): Flashblock

What problems does Adblock cause?

I'll disable it for Duolingo

Ghostery addon also had the same issues for Firefox...

I disabled Adblock for Doulingo, but still have problems...
I'll try to find, what other extensions cause problems.
