Doesn't work.

good

It doesn't work on all domains (ie. co.uk). It would be wonderful if you could put your plugins on Github and link them here in addons.mozilla.org. This would definitely help tracking issues and you would probably get some help as well. Thank you very much!

Hi dude, your add-on doesnt work anymore. Do you have any clue on what is going on ?

Alllows browsing, fails as soon as you click an image to take a closer look.
Removed.

No longer works in Firefox v56.0.2+

Does not show up anywhere on tool bar

I installed the add-on. Restarted Firefox. Went to Pinterest and the first thing I saw was a log on / sign up screen.

Working again for me with v3.0!

Was working great, but seems to have stopped. v1.3 FF 54.0.1 32 bit
Update: 1.4 working perfectly now - many thanks for the fast fix!
