Needs update for Mozilla 44.0.2! Rated 4 out of 5 stars

Tab and toolbar fonts are so tiny as to be almost illegible. :( Otherwise, love this add-on.

HELP NEEDED Rated 5 out of 5 stars

After the latest update 44.0.2 of Mozilla it doesn't work anymore. And this is the only addon that changes the fonts. Very good addon anyway.

unavailable for linux ? Rated 1 out of 5 stars

i see that the TF&S Changer stopped working and now spite of appearing installed it is liested as "not available for your platform" and in fact doesn't appear in the bars. I mean.. really? Not supported for the latest firefox for linux 32bit (Debian)? Really ?

Excellent Rated 5 out of 5 stars

REF: ThunderbirdBird 29.0
This add on is effective, and very simple to install and utilize. My need is related to providing instruction in part via printed screenshots, in which standard font is virtually unreadable without a magnifying glass. This add-on does the job perfectly, and is quickly and easily switched from standard to magnified and back. Thank you!

Working again Rated 5 out of 5 stars

Okay, I was quite angry some days ago because a program update destroyed nearly everything in Firefox (and could not be reverted) but the new version works with Firefox 44, icon is back again too etc, thanks for this

I was wondering how I was going to read my screens without this, and I'm very glad that it's fixed for the latest Firefox.

No longer working with FF 44.0 Rated 5 out of 5 stars

Today I updated FF to version 44.0 and Theme Font & Size Changer is no longer working. Hope an update to fix this is released soon. Thanks.

I think the problem is with FX and not the extension Rated 5 out of 5 stars

This is a very good extension that addresses several functional and aesthetic issues.

Unfortunately, in the relatively recent past, changes in the Firefox code have wreaked havoc with it.

Several people have mentioned that the most recent update (43.10) doesn't work, but I don't think it's quite that simple since updating the Fx Nightly today (25 Jan) also broke version 43.4.

All I can say is that it still works on Firefox ESR. It doesn't work - at least on my machines - on Nightly (v. 46 and - as of today - v.47, and it also doesn't work on v. 44 Beta.

Another issue users need to consider is the other extensions they have installed. I've also found that NoScript is also partially broken in a way that seems to be related to the status bar.

All in all, I think the issue is quite a bit more complicated than it appears to non-computer experts like me.

My thanks to the dev, for whom I'm sure this is as troublesome as it is for us end-users, if not more so.

A fix would certainly be nice, but it may not be completely in the dev's hands.

My icon Vanished, Where did it go? Rated 5 out of 5 stars

FF 44 is 100% the problem. This addon continues to work great as soon as you remove 44 and re-install FF 43.04. What is it with these FF updates? They seem to cause more problems than anything useful.

Excellent add-on except . . .-- Updated Rated 5 out of 5 stars

This is an excellent add-on that is more or less useful for everyone.
I used to do the same thing by hand editing the chrome file, but that was pain.
Thanks again for a very excellent add-on.
The only thing that has come up with newer version of FF (now at 45.0a1 (2015-11-05)) is that the icon is lost. I have looked everywhere that I could think of but to no avail, the bookmark bar font has reverted to the default!!

Update: Even with the latest update (42.3), I cannot still find the icon to change the fonts etc... Am I the only one with this problem!? If not can someone tell me where I can find this?

Update:
New update i.e. version 4.3 works perfectly well with the nightly now.
Thanks again for a very good add-on.

Good for scaling things in situations where you have a high dpi display and do not want to use the OS's own scaling for various reasons.
