Ok, its working. But its pretty useless. There is no catalog where you can search all your hightlight for keywords. There are no labels you can set to find articles in the future again.
And PDFs in the internal viewer are not supported at all.
So you have to search all your bookmarks to refind articles for a keyword or a label again later on.

A extensão é excelente, queira sinalizar com 4,5 estrelas pelo simples fato de que a utilização da tecla de atalho Alt+A ou Ctrl+A para acionar a extensão acaba conflitando com as configuração do navegador.

Ao teclar Alt+A abre o menu Arquivo do navegador enquanto Ctrl+A seleciona todo o conteúdo da página.

Se os desenvolvedores alterarem essa configuração de tecla de atalho para acionamento da extensão a ferramenta merece nota 10.

I love this highlighter--it is easy to control and turn on/off. I would really love an option to add a comment to a highlight, though.

Causes firefox to REALLY lag

If you're looking for a highlighter which simply highlights and save the highlighted parts this is the best one for that. However, you cannot take any type of notes from it but otherwise its perfect.

I like it , but unfortunately I can use neither the shortcut key Ctrl + A (all the page is selected) nor the shortcut key Alt+ A (that pulls down the menu Affichage from Firefox (french version) . Could another shortcut be possible ? Thanks!

The extension is spot on for what i need. But it lack some features that i would love to see added in the future. one is to have a place where you can see all the websites you highlighted in.

Very simple and works well but could use more features.

It looked very promising, but I found out that it's not compatible with Midnight Lizard addon. The highlights are almost invisible and the Color Toggle button don't work.
When I turn-off the Midnight Lizard, highlight something and reload the page, all highlights become lost.

- add an option select all highlighted text
- quick access to copy all ? (and select all) 2 other icons in the individual popups

It does not save highlighted phrases any more, which was the reason I installed this app in the first place. It just says "There was an error loading your highlights. Please try refreshing the page". It's still great for just highlighting text though.

Best highlighter add-on I've come across, and I've tested a few. Hotkeys, highlight saving, convenient popup menu for most necessary actions. Thank you.
