FF 10 seems to be the problem Rated 5 out of 5 stars

I found that even without Nosquint installed, FF 10 was painfully slow, and some pages required repeated clicks to load. So I dropped back to FF 5.0, and bingo, pages load fast, and Nosquint seems to be working fine.

This review is for a previous version of the add-on (2.1.5). 

greatly slows down firefox Rated 1 out of 5 stars

I have used Nosqunit now for a couple of weeks. I applaud the attempt, but pages in FF 10 either will load slowly, or not at all (have W 7, 64 bit, 12 GB ram). Some pages, as in weather.com, will not load at all -- e.g., the 10 day forecast. Is this an issue with FF 10?

This review is for a previous version of the add-on (2.1.5). 

It's obviously not normal

Something is clearly wrong. I can't possibly know what until I gather more details. I assume you upgraded to the recently release 2.1.5? It could be a bad interaction with another extension, or maybe Firefox itself (see https://urandom.ca/nosquint/#faq-slow).

Can you please contact me at tack-nosquint@urandom.ca so we can work through this over email?
