I started to use Safari as my primary web browser, but there were some things that I really missed from Firefox. Luckily, the Safari user community has bridged this gap with plugins:
Keywurl is a Safari plugin that emulates Firefox’s Smart Keywords, something that I use a lot in Firefox and can no longer live without in my web browser.
Since the addition of Session Restore in Firefox, I now expect my browser to reopen with the tabs I had open when I closed. The ForgetMeNot plugin adds this feature to Safari.
I am now a fully converted Safari user for browsing the web, though I still use Firefox for web development.
