I'm also having an error today. What I'm experiencing is not that Adblock plus doesn't block ads, but that the filters are deleted on every browser restart.

David, I guess Adblock Plus should use read() instead of readTo()? The idea here was offloading the garbage collector a bit by using only one array buffer.

[David Teller [:Yoric] - still alive but not very active]

If you could migrate ABP to use `read()`, that would be great.
Indeed, `readTo()` was introduced specifically for the reason you mention, but it turns out that this prevents the JS team from improving the garbage-collector.
It shouldn't be too hard to write a variant of `readTo()` that would work, but it cannot keep the same API either way.

[David Teller [:Yoric] - still alive but not very active]

Wladimir, do you want to migrate to `read()` or would you prefer a replacement `readTo()` first?

Something along the lines of:

/**
 * Optimized variant of `read` that doesn't need to allocate a buffer.
 *
 * @param {TypedArray} buffer The buffer that will contain the data.
 * This buffer is neutered by the call, and cannot be reused.
 * @param {*} options
 *
 * @return {TypedArray} The buffer, with the data.
 */
readTo(buffer, options)

No need for an intermediate solution, my change is already up for review: http://codereview.adblockplus.org/6083164824928256. I think it's too late for a release next week, we should release on November 11 if everything is ok.

Adblock Plus 2.6.6 is out (reviewed by AMO a few minutes ago), the issue is fixed there.

Given that this is in the Tech Evangelism component, I'm resolving as FIXED.
