After searching for a long time, it turned out to be the sound emitted by this extension!。。。

because of old age i need this kind of technology autofill is the best fiend i have now

The extension seems awesome, but I can't make it work. Rule creation works like a charm but I can't execute a profile once on my blank form, even after setting a custom shortchut for this profile... Any guess? (I'm running the latest firefox version)

does not fill in a single thing. nothing.

WHY THIS AMAZING ADDON HAS SO FEW USERS!

Most of the time it'll work flawlessly on it's own. But sometimes it might require a user to manually edit profile to to make it work properly (not dev's fault). However, I will request the dev to get the "Recommended addon" batch so that Firefox addon-store suggest this addon to more users. It might make a big difference. Thanks for this very useful addon.

works very well - fully customisable - saves time - useful !! and no browsing speed penalty like so many of the "big name" data gathering pigs - thanks dev X

Очень удобное дополнение. Лучшее из подобных.

it worked on the recommended test page but not for two "real life" experiences, so it failed my test

Wonder full flag in, My time Saved

Does work for simple pages. Does not, for example, on pages with tabs or expand fields. For example: `https://docs.google.com/spreadsheets` Needs to click or expand all buttons/fields on a page to load the hidden fields. Need to scroll down to load the end of page.

Didn't work.
