Recently, my Firefox browser started loading without the extensions I’ve installed. I run my Firefox browser off of my 4GB Cruzer using the PortableApps suite.
When Firefox loaded, it would load without a single extension, but when I opened the “add-ins” box, it listed all of my extensions.
Here is the thread where I found my particular solution. I was able to get Firefox to load my extensions again by modifying the files within my Firefox profile (find it in you user account appdata folder). I deleted extensions.cache, extensions.ini and extensions.rdf. When I started Firefox the next time, it regenerated these files using the extensions that were in my profile (folders like {2fa4ed95-0317-4c6a-a74c-5f3e3912c1f9}).
Problem solved for me. I did take notice that Firefox is blazing fast on start-up. . . until I load a ton of extensions. With the number of extensions I have, it’s more like Visual Studio since I’m loading up a whole suite of web development tools. Firefox is just as much a web IDE as Visual Studio – including the RAM usage.
I agree with all your comments regarding Firefox. I’d add that on the Mac it only gets worse. It hangs all the time and eats CPU like candy.
Now I’m really curious about the list of extensions you are using for firefox
This happened to me once, so now I have FEBE and CLEO installed. I keep a current backup so if it ever happens again i just rerun my single .xpi package.
