Definitely, the Vimium team needs to fix a lot of issues on Mozilla Firefox

It doesn't work very well in modern web, when some websites use fake buttons as divs with event handlers. They aren't highlighted when I press f.

Truly a cool addon, feels really practical to use.
Would love to have a shortcut to completely disable/enable it, though, since it does get a little awkward in some websites. This is an Emergency!

Można dużo robić klawiaturą. To działa całkiem fajnie. Gdy boli ręka od myszy, jest alternatywny sposób obsługi przeglądarki.
Ostatnio pogorszyło się wyszukiwanie poprzez "/". Na bardziej skomplikowanych stronach zawiesza się po wpisaniu pierwszego znaku. Wpisywanie kolejnych znaków frazy do wyszukania nie jest już możliwe. Wyszukiwanie tradycyjną metodą "ctrl-f" działa.

/ search interfere with built in quick search and does not work well, sometimes switching to mozilla's search while leaving addon search open, and esc do not closing addon search.
Word navigation in caret mode like w or e moving caret by one symbol forward, while b moves back by word.
Wish you could make changes to standart quick search and caret mode (f7) so it will fit nicely into gui and will not dublicate commands, but i dont know is it possible or not.
f - overlaping small font links. hard to see what they are linking to. maybe make markers smaller with shifting to empty spaces between lines.
no appearance customization.

It works fine, but sometimes the hint-mode generates duplicate characters combinations for different links and gets stuck.

Broader website ompatibility and better link and clickable object detection would be great,
I wish this worked well with widely used disqus website plugin.

The copyCurrentUrl command doesn't work. Please fix this issue.

I installed this as a desperate attempt to keep some Vimperator functionality as Mozilla is about to drop support for its "legacy" addons. It does a good job of replacing "follow hint" and basic page navigation but it cannot possibly compare to the full awesomeness of Vimperator. But as the developer writes: it is currently the only Vim-like addon compatible with future versions of firefox.
