Every time I open a new tab with the new tab button, Firefox freezes for a few seconds and crashes. I can open links in new tabs from sites, though.
About:blank doesn't crash it. When I re-open Firefox, it says that it's had trouble recovering tabs and everything I had before except the new tab recovers just fine. Except for one time, where I did something differently somehow, until I realized that I can choose which tabs to open and which not to.

That is a problem with the Shockwave Flash plugin.
You can check for problems with current Shockwave Flash plugin versions and try this:
- check for updates for your graphics drive drivers
https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration - disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
- disable hardware acceleration in the Flash plugin

What is the current setting of the new tab page? You can try to set the browser.newtab.url pref to about:blank to see if that helps.
- the default new tab page with the tiles is about:newtab
- the default home page is about:home
- for a blank page you can use about:blank
Note that the browser.newtabpage.enabled pref should be true to use the page set via browser.newtab.url as the new tab page.
See this article about the New Tab page (about:newtab):
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
- Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
- Do NOT click the Reset button on the Safe Mode start window
