  • I set firefox and addons to not update past 56.1 but now Theme Font & Size Changer is not working on any of my computers.
  • Oh, come on. What now? Please do fix this! Old versions no longer work...
  • Alles war perfekt funktioniert nicht mit FF 55.0.3
  • What happened with this add on, today? On every pc in my family, 7 computers total, TFSC stopped working. No updates were installed. Automatic updates are turned off. Every computer hast FF ESR 52.5.3 64 bit installed.

    Did everyone get a "deactivate" signal from an external source??? Am I the only one with this theory?
  • So this guy Berin or Gerin wants access to all data for every website I visit in exchange for the use of this add-on? This guy has lost his mind. I'd rather buy it (one time) with no access to him for anything.
  • Helpful info.. (I've been here before because of nonworking TFSC) and my old eyes need help, like a lot of peeps showing up here :)
    First, I only use PC Waterfox 64bit 54ver. and I use Thunderbird 32bit 52ver. I have ALL my addon's turned off and not to update including WF and TB. I realize now, That Firefox and Thunderbird will never add some helpful font adjustments for our bad eyes :(
    If you read through the reviews. You'll see some info reviews on how to download and install a non expiring version of TFSC on earlier version of FF, Waterfox, TB. I only wanted to help people because I feel their pain on not being able to see and need help and remember to turn off all updates that includes FF, TB, WF. . I still want to give props to the Author of TFSC. Thx you!
  • it did work fine until today..... suddenly i can´t access it anymore and everything is small again.
    deinstalled and reinstalled the addon but it does not appear in thunderbird 52.5.2.

    don´t know if mozilla messed around again... can only say i is not working anymore. hope it will be fixed soon.
    i thought the web extension stuff ony affects firefox 57??
  • Why the Version 56 even on Firefox 56.02 stop working !! why you do that ???? the add_on working great until this afternoon !

  • Ich finde das add-on Spitze auf Thunderbird. Aber leider scheint es auf meinen Firefox ESR 52.5.3 nicht zu funktionieren? Schade. Warum ist dies so?
  • Great addon firefox menus are too small to see without it.

    This addon shouldn't exist there should just be a firefox option to increase menu font size but there's not, and this addon filled the gaping usability design flaw left by mozilla.

    But Firefox killed it. : (

    In firefox's constant quest to make a crappier version with less features and capabilities every revision, they made it so this addon will no longer function for safety reasons.

    Thanks Mozilla I'm safer but now I can't see the menus. >:(
  • good
  • this sucks - there is no where to change the size of the text anywhere - so damn frustrating.....FUCK!!!
  • I just updated Firefox and I can't change my Theme back to what I had it on.... It's says 'disabled' and when I try to enable it, nothing happens at all... How can I fix this??
  • doesnt work anymore
  • This was a great extension before Firefox updated to the Quantum version. Most of the functionality is now gone and the extension is basically worthless.
  • It's currently useless. All the great features it used to provide in past versions are gone due to the release of Firefox Quantum. I hope the author finds a way to bring them back in the future.
  • The idea is not bad.
    But the terrible behavior, when the add-on simply turns off and stops working without indicating the reasons - is very annoying.
    It is understood that it needs to be updated in this case.
    What for? It still working fine! I dont need any updates!
    It will be easier just to install STYLISH and add a style:

    @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");
    @namespace html url("http://www.w3.org/1999/xhtml");
    @namespace svg url("http://www.w3.org/2000/svg");
    * {
    font-size: 13px!important;
    font-family:Microsoft Sans Serif !important;

    and set
    layout.css.devPixelsPerPx = 1
  • No longer working for the new version of Firefox.
    I will review my rating once fixed, as of now, dont bother.
  • For all those complaining about the latest version not working (aside from the developer's action and more importantly, the handcuffs imposed by Mozilla on FF 57+ which kills and prevents many add-ons from EVER working with Web Extensions) - stay with Theme Font & Size Changer version 56, available here: https://addons.mozilla.org/en-GB/firefox/addon/theme-font-size-changer/versions/ and stay with Firefox version 56.

    You can lock the current version of any add-on via the Add-on Manager: click on the "More" link next to an add-on and change "Automatic Updates" to "Off".
    Firefox still alerts if an update is available but doesn't automatically update it, giving you the opportunity to check the changes made/reviews BEFORE any changes get made.
