I COULD SEE THE WORDS

j'adore cette extension à cause de ma vue ; mais en ce moment , elle ne fonctionne plus ; pour moi c'est embêtant

I need this app and yet FF has made it so it can't be used. Mozilla needs to change its course. The full themes were incredible, the main reason why I used FF. This is a FANTASTIC app.

This was the only way I was able to use Firefox comfortably. Firefox 57 ended all that. The reason I used FF was because it's customization. I understand what FF is trying to do, but it has turned it into Chrome or Edge...UGH! So I reverted to version 56. I thought TF&SC would then, but no luck. Is there a way to make it work for older versions of FF?

Loved this until 57 was released.

But here's a question.

If you look at the page for T&FSC, it says it was updated on November 16.

Yet it still doesn't work with 57 which was released 2 days BEFORE.

What gives?

Please make available for Firefox 57. I know it's not your fault that this extension doesn't work anymore and that Mozilla's latest Firefox makes it incompatible. I've been using this Add on for many years and, like a lot of other folks with aging eyesights badly need it. Shame on Mozilla for not only making you incompatible but for also giving the middle finger to us older users by making their menu items unreadably small.

Great extension, I hope it not drop. If someone will help, there is a small means of partial replacement to this addon.
1. Place/Create/Add next file "userChrome.css" into "chrome" subfolder in your profile, e.g. C:\Users\usename\Appdata\Roaming\Mozilla\Firefox\Profiles\cdar87xx.default\chrome;
2. Fill userChrome.css next content, for example:
* {font-size: 10pt !important; font-family: "Roboto" !important;}
3. It means that you have this font already installed. You can set your own font-size and font-family values, ofcourse;
4. Restart FF.
Now it looks closely than I has with TFSC.

Can not change the font size.

It was hard to find the button under FF57, and then when I found it I discovered that this addon no longer does what it used to do, which is make Firefox usable for me. Very disappionted. Not your fault, I know. The only workaround I found was given here: https://support.mozilla.org/en-US/questions/1184537, and involves changing about:config values.

I can't tell you how much I hate you for changing my Firefox v51 back to tiny font just because you are having trouble with v57. What made you do such a shitty thing?

Can't make it work anymore!!!!!!

LOVED this tool before the 57 update. Everything is ssssoooooo tiny now. Please update so I can see again!

My reviews are not being posted - am I blocked?

The FirrFox quantum default appearance is horrible, okay simplicity but leave the black !! Life is colored.

Do not work for me! Please update for all functions.

It is not working for me

Until this stuff is fixed for newer Firefox use this hack to get font size bigger:
create userChrome.css in the profiles /chrome folder and enter

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* set default namespace to XUL */

menubar, menubutton, menulist, menu, menuitem, textbox,
toolbar, .tab-text, tree, tooltip, sidebarheader, statusbar {
font-size: 20px !important; }

THE NEW THEME AND FONT SIZE CHANGER IS TERRIBLE, I WANT THE OLD ONE BACK. IT IS CONFUSING AND THE
FONT CHANGER DOESN'T WORK. I USED TO BE ABLE TO HOVER OVER THE THEMES TO CHECK THEM OUT AND
THAT IS GONE AS WELL. WHY DO YOU HAVE TO KEEP CHANGING THINGS? YOU SHOULD HAVE LEFT WELL ENOUGH
ALONE. I WILL PROBABLY DUMP FIREFOX BECAUSE OF THIS.

Because of the limitations in customising Firefox 57 I will use Waterfox until it ceases to update. Why remove the functionality of this addon with the latest update? Please restore all functionality so that people who are happy using variations of Firefox which allow the old extensions can continue to enjoy your great addon, thank you :)
