Link url replacer

Doesn't work.

I enabled its right to function in incognito and tried pattern: "https://www.google.nl/imghp?hl=nl&ogbl" and replacement: "https://www.google.nl/imghp?hl=nl&ogbl&safe=off" but it didn't do anything. It was supposed to turn off safe search when I clicked the "Images" link in google. Manually changing the link works fine so the extension isn't working. I also tried it without the "https://" and without "https://www.", but that didn't make it work either.

The "+ Add profile" button does not work
