What is the value of "Remote Processes" in about:support?

What is the value of browser.tabs.remote.autostart in about:config? Default is true.

It's true. You didn't say to try changing it. I did anyway and it didn't help.

You should not be changing the default value. Some people have reported issues with uBlock Origin when it's false.

Sorry, I missed this part the first time.

There is no "Remote Processes" in about:support.

Still present in 67.0b14 64 bits.

Not present in 67.0b14 32 bits. I hadn't checked under previous 32-bit veesions.

Apparently same bug as https://github.com/uBlockOrigin/uBlock-issues/issues/416 (version 67 Nightly released on 28 January 2019), perhaps also https://www.reddit.com/r/uBlockOrigin/comments/b7warj/problem_with_ublock_with_v6602_firefox/

Solved by removing and reinstalling the extensions.
