Needless to say, this is a great extension. Especially when it comes to regular expression support, it's unbeatable. Because nowadays, it's hard to find a better extension with regular expression support in the Firefox Add-ons Store. Considering the color markers next to the right scrollbar, I think it's almost a replacement for Firefox's own FIND functionality.

Speaking of the color marker on the right, I know that its function is to make it easy for me to find the location of the highlighted text, but it doesn't seem to be horizontally aligned with the text content, specifically, any higher than the text highlighting.

Finally, the only suggestion I can make is that the "copy" search rule doesn't seem to work as expected. This is because when I want to copy rules from other pages, it always copies the links to the domains contained in the rules from the other pages, which results in the copied rules not being immediately applied to the current page I want. I might as well just copy the search text and create a new rule on a new page if I want to achieve my goal, but that seems a bit tedious.

I hope this is just a personal operational issue for me, and thanks again for the extension!
