asks for lengthy permissions and then disappears.
There is NO ICON!
No Controls.
What is it doing???

Appeared in New Window
Wants me to setup an account there.
How about keeping my search filter data HERE!
REMOVE!!!!!~!

As of Firefox 90, and from the comments a lot earlier, this add-on does not work at all. It's as fake as a $3.00 bill. Even when the area does show up (rare) where you can put in a URL, it will not filter it from results even if you ask it to. It also states: "To avoid littering the GUI with buttons, the Google Search Filter button only appears when running searches on Google." Meaning a rediculus to use even when it apparently used to.

The icon to access the GUI interface not apear on google or any other page.

This extension enhances google search result readability more than I expected.
Adding some color preference would be better.
And, some nifty icons showing with on-mouse-over event might be better than every solid 'highlight, hide' text.

Now works fine. But it didn't for the first several page loads. Probably some strange bug?

Would be nice to be able to access the interface without actually having to run a search in Google.

Cool idea. It will be cool if you can set custom colors for domains

please add a color tag to highlight
for example +#ff0000+

Work for 2 days now does nothing, Goal is to filter Amazon, google, bing, facebook turn all of the giant tech to OFF.

It's the coolest, but auto-updating add-ons are now corrupting files and causing Firefox to freeze.
I solved it by reconfiguring Sync.

No longer works.

I've been looking for this for years. I guess Google didn't want me to find it. This should be built into every browser. Thank you!

Works fine! Only downside is it's not yet updated to handle dark mode properly...

Nice work.

works
