Works flawlessly, except when you open a second window, in that case, if the search opens in a new tab, it doesn't matter if the setting is "next to current", the new tabs always opens rightmost of everything.
This only affects a new window, searches in the first main window behave correctly

reverse image search by google doesnt work

Exactly what I've been looking for in a reverse image search add-on. My only issue is that Google wasn't working, but that can be fixed by manually replacing the "Search Variables (One per Line)" section with:

sbisrc=cr_1_5_2
image_url=::$URL::

No longer works on google, great otherwise and i hope they fix it

Not a bad tool to use for locating hard-to-find arrest mugshots on web search for clients using our mugshot removal services.

Sadly in not working anymore on Firefox mobile. Please make this work, it is a pain to try to search imagens while using a smartphone.

Good extension overall, allowing to customize our searches freely, and especially the "alternative method" possibility when a classic search method does not work for certain websites.
This being said, it would be really good if the extension could save this "Use Alternate" option for a URL/Domain, and remember it for future searches on this domain. And it would be good too if turning that alternative method on wouldn't affect other domains during the same session. Having to turn it on/off constantly is annoying.
Thanks for your work and consideration anyway!
