Mozilla Firefox seems slow to start
1] Use a Blank Tab as Startup Page & New Windows
It is best not to use a website as a startup option when you launch Firefox. Just use a blank page. When you use anything else, it waits for the site to load completely and feels slow. Make sure to choose the same option for new tabs as well.
Click on the Menu on the right, and then options. Switch to Home preferences, and select Blank Page for Homepage, new windows, and new tabs. It will make sure everything loads up fast, especially if you keep opening new tabs now and then.
2] Check on Firefox add-ons & plugins
Many a time add-ons and plugins slow down Firefox startup. It could be during the launch or after you have used it for a while. Sometimes it could be because of the graphics driver or hardware acceleration. Check out our detailed post on resolving Firefox problems with add-ons and plugins.
