Also, I only adopt new browser plugins very sparingly, because the chance of some random extension getting bought out by a shadowy ad and malware firm is way too high, and Mozilla doesn't assure me with the level of vetting they do (nonexistent, compared to F-Droid or any mainstream linux distro.) Why is this such a problem for Mozilla? They even try to make it difficult to get extensions from anybody but them, so a third party extension store that actually does due diligence is basically off the table. I can't even install extensions straight from a developer's github, which wouldn't be as good as a trusted 3rd party repo, but still better than Mozilla's status quo. In fact, so called userscripts loaded through one trusted extension actually feel a lot safer than normal extensions.
