  • Don't wait until the extension is installed to tell us it doesn't work. You're just wasting our time.
  • I think that Firefox should give its browser users an app with exactly the same functions as that offered by Theme Font & Size Changer.
  • extension not working with the new version (63.0.1) of Firefox
  • It's not working most of function with FF62. Why developer leave this useless addon on the Firefox addon website? Please remove it from website!
  • It seems to be out of date. Doesn't work on new Firefox
  • Does not work on Ffox 62
  • not working even I am still using FF52
  • I only want to change the font color in my add-on. The background is sky blue and the font is white. I cannot see a thing.!
  • Totally broken and useless, but does not say so before install
  • I had stopped upgrading FF because I would lose TF&SC. Tonight I forgot and "upgraded" FF. Now my bookmark fonts are so small my old eyes can't read them easily and tire.Keep this up and I'll be forced to use Chrome....
  • Does not work with the current versions of Firefox, a fact not mentioned in the writeup.
  • It still doesn't work. Not on TB, or FF.
  • .
  • Not working on Linux since FF moved to Quantum ((FF57?)
  • Periodically stops working. Now, April 2018 it is not fixed for weeks ...
    The wanhunglo fix mentioned below works!
  • The thunderbird version of this addon breaks regularly rendering TB unusable because of the tiny fonts. I URGE ANYONE TO GO https://bugzilla.mozilla.org/show_bug.cgi?id=1453928 REGISTER AND UPVOTE THE BUG/COMMENT SO THAT THUNDERBIRD ADDS A FONT INCREASE OPTION BY DEFAULT
  • Once again not working anymore, because the id!ot author has built in a 90 day time limit after which the addon silently fails. Change build date (unix timestamp) or remove the check function in line 1382 of bootstrap.js to make it work again. Or visit wanhunglo (dot) com to download a fixed version.

    Why is this addon still listed? Reported several times, this sh!t has been happening for the past three "updates" every single time!
  • absolutely not working extension
  • No funciona desde la última gran actualización
