Review for Key config by Firefox user 5bb495
Rated 4 out of 5 stars
Some site are conflicting with this addon: for example typing numbers in text field at https://confluence.atlassian.com triggers hotkeys.
And more such incompatible sites are coming (even addons.mozilla.org), probably they started using some intrusive JS framework.
