Big fan of mozilla and firefox. I&#x27;ve been defending it for years, but now I&#x27;m having a hard time. It&#x27;s slower in almost any case than the competition, from initial rendering to switching tabs. Some stuff hang the page completly. Watching too many videos or scrolling too much twitter slow down the browser to a crawl even after closing all tabs and require a restart.<p>I&#x27;m not using firefox out of sheer ideology and support for the FOSS community, but it&#x27;s not the superior product I used to sell to everybody.
