ublock auto-update issues?

[gorhill]

As reported in a Wilder Securities's thread:

I probably did not word the problem correctly. The browser starts just fine. But sometimes, after I start browsing, I notice that it is no longer blocking some objects that had been previously filtered. When I investigate, I notice my filters are no longer present. I also notice that the host files in the multipurpose section are all unchecked.

I believe the problem is happening after ublock auto-updates. I'm using Ubuntu and not using any anti-malware.

Another observation that may be related: After this failure, I am unable to import my saved personal filters (I had previously exported the file). When I click "import and append" nothing really happens ... And "Apply Changes" remains greyed out. To import I must first manually edit the filter with a few characters. Then I can click "Apply Changes" ... And then I can import my previously saved filters without problem.

Need to first validate whether there is an issue with auto-update of filter lists.

Forced various auto-update code paths, all looked fine. Waiting for more feedback.

Thinking of it, could have been caused by some cleaners. I read somewhere Avast "doesn't like" uBlock.
