Excellent, but now flawed. Rated 4 out of 5 stars
This has gone from being a favourite add-on to being a major irritation.
Seemingly since the latest Firefox release the otpion to check only appears for the first use when the browser is opened - and then fails to appear.
To make it reappear, the browser has to be closed and opened again.
Any chance of a fix soon, please?
PS. Still 4 stars because it's excellent when it's working!
