Related issue: - https://github.com/uBlockOrigin/uBlock-issues/issues/974 Related feedback: - https://www.reddit.com/r/uBlockOrigin/comments/fuscia/ The race condition was that a content script could query the main process to retrieve cosmetic filters while the cosmetic filters had not been yet fully loaded into memory. The fix ensure that an already injected content script will re-query once the cosmetic filters are fully loaded in memory at browser launch time.
