Sorry, somehow I missed destrius' message above before posting mine. I checked layout.css.dpi and it said "-1". Changing it to "96" immediately fixed everything. Every page on every tab looks perfect now.
As a test, setting it back to -1 reverts each page to exactly the way it looked with huge fonts. -- Bizarre huge fonts in Firefox https://bugs.launchpad.net/bugs/224471 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
