For some reason the eraser only works through the keyboard shortcuts and is only highlighting using the first colour you chose for the page.

This add-on does not save notes!

Does what is supposed to, but could be better developed

When background is changed - font is barely readable :(

I don't know what to say except that I have tried many add-ons (To Annotate and Highlight Web Pages) and this is the best one, as it does not require a website account or any special information to work.

Jus suddenly stopped saving.

Does not work on pdf's.

Does not work on pdfs? Unless the instructions are unclear, there is no highlight of any kind added to the page after clicking add and then selecting a colour

does not save highlights

Didn't save my highlights on a STATIC web page. Lost all my notes for my research assignment. Why don't ANY of these highlighters actually work. It worked when I initially tested it on the web page, but when I had my browser closed for a couple of days it didn't load them. At least let us download the highlights data file like the other one that doesn't work.

does not save highlights properly

Just installed and tested. Worked perfectly, just what I’ve been looking for. Except for shortcut keys which seem to already be assigned to something else. Not a biggie. Can just re-assign If it continues to work.

All Highlights are lost as soon as page is refreshed!!! What a waste!

does exactly what it promises. Thanks Prateek!
