Adblock Plus filters are reset on each browser start

Cause: Chrome issue 103018, file storage got corrupted

Solution: Go to the directory where Chrome stores your data (on Windows: "%LOCALAPPDATA%\Google\Chrome\User Data\Default") and remove the folder "File System". This won't make matters worse: the data in this folder is already corrupted. Removing the directory will allow Chrome to create it again and use it correctly.

Adblock Plus doesn't block in-video ads, background images, XMLHttpRequests

Cause: Google Chrome currently doesn't allow blocking any of these request types

Solution: Update to Chrome 17.

Text-based ads sometimes don't get blocked

Cause: Delay in blocking caused by the way Adblock Plus currently blocks things

Solution: Update to Chrome 17.
