Tuckner said in an email Wednesday that the most recent status of the affected extensions is:

- Of 45 known Chrome extensions, 12 are now inactive. Some of the extensions were removed for malware explicitly. Others have removed the library which was a scraper.
- Of 129 Edge extensions incorporating the scrape library, eight are now inactive.
- Of 71 affected Firefox extensions, two are now inactive.

Some of the inactive extensions were removed for malware explicitly.

Others have removed the library in more recent updates. A complete list of extensions found by Tuckner is here.
