Works great on PC.
Not available for Firefox on android.

Only hide web search results. No functionality for videos/images.

It seems to work well at removing results, however this addon adds an annoying arrow when you hover over results with no way to disable it, so I cannot continue to use this addon.

Maybe three stars is a little unfair as it did block many links when clicking on the search result, but didn't block them from the search itself. Unfortunately like so many others it didn't block the search result, and prevent my searches been taken over by Pinterest.
I far as I'm concerned, Pinterest is far worse than many add sites and should be treated as such.
I'd change browsers without a second thought if they claimed to block Pinterest.
Even if it was owned by Google.:-)

Very nice, when it works, but apparently prone to bugs -- as of early 2021 it is unable to add more than 140-odd addresses to the filter list (bug already reported)

After prolonged use, I can’t access the extension settings - when I click on the three bars in the top left, an empty window pops out. This happens on two different PCs. As a result, I can’t access the settings and I can’t save the list of my sites. During use, I already had two problems, due to which I lost all of my entries :( Until the extension has the sane ability to save data, I see no reason to use it!

I liked the addon very much. until now, as I tried to export my 171 entries. But there is no menu anymore, therefore also no export function!?
