Replace Note area with word definition Rated 5 out of 5 stars

That will be perfect if the empty Note area is replaced with word definition (that is, look up the word from a dictionary).

Needs Help Rated 3 out of 5 stars

It works sometimes and you need to refresh the page to make it work also different colors would be nice too.

This Extention is Corrupt: creates 100's (literally) of mozStorage instances --> WILL CRASH YOUR FIREFOX Rated 1 out of 5 stars

This application is corrupt and should be removed.

A firefox/mozilla bug has been raised against it:

Bug 1234037 - Vocabulary Highlighter extension creates many redundant instances of mozStorage

For further info see https://bugzilla.mozilla.org/show_bug.cgi?id=1234037 , including the screenshot.

Cannot use Rated 1 out of 5 stars

I need to change keywords daily. For some reason Vocabulary Highlighter insistently highlights erased items even from empty dictionary. Sometimes it does not highlight active words. Uninstalled.
Moved to Phrase Highlighter, although it renounces to work with frames.

Great and promising! Thanks. Do you still support this add-on?

Could this addon create some hotkey functions? Rated 4 out of 5 stars

Good addon! But it will be greater if provides hotkey functions. Clicking right button, click add, click ok, it cost three actions, while It will be more convenient if three actions can be changed by one hotkey.

Firefox started randomly crashing Rated 3 out of 5 stars

I would really need the functionality of this addon, and it worked well for the most part, but sometimes it didn't highlight the word list when loading a page, even after reloading and turning the addon on and off.

Also my Firefox started to crash randomly several times a day after installing this addon, so I had to uninstall it.

Rated 4 out of 5 stars

Everything works fine except for reports. Every time I want to have a look at a report, it opens in a new tab but there are only empty columns. I'd like to have a list of my highlighted vocabulary so that I could print it out or use it to make flashcards online. It's much less useful to me if I can't do that.

One of a kind! Very useful! To the developer, please keep this addon alive!

Still has issues Rated 3 out of 5 stars

This would be a great program if only it would stop crashing every version of Firefox that now comes out. It also still has issues with not being able to remove highlighted words once they've been totally removed from the program. I love the concept of this program but sadly it really no longer works. I'm hoping the creator finally repairs it.

Can you please make this available for Android version of Mozilla Firefox?
It's my favorite add-on and also the backbone of my learning. It is very-2 useful which I have been exploiting in my learning.

The remove function not work Rated 5 out of 5 stars

Everything goes well only the remove words not functional. The words will always show highlighter even after it has been successfully removed. Could you please fix it,as the database growing larger, some unused words need removed. Thank you for your great work.

Just a tip Rated 3 out of 5 stars

I used to love this, it really transformed the way I worked, but as others have said there's a stability issue at the moment. Until the author gets it fixed I would recommend Phrase Highlighter which has similar functionality and doesn't break FF as often.

Rated 3 out of 5 stars

Exactly what I need, but, like others have mentioned, it keeps crashing Firefox.

Rated 3 out of 5 stars

The functionality is excellent, except when it locks up or crashes Firefox. About 10% or fewer of the crashes have a window displayed that the script within Vocabulary Highlighter is unresponsive, and I can stop it. Most of the time, Firefox just crashes. Removing this add-on puts a stop to the crashes.
