Doesn't work with either firefox or thunderbird.

TFSC toolbar button was shown again!^^; Rated 5 out of 5 stars

I have set my Tb body size smaller and wider only through this program
instead of Windows system display setting.

Thanks Baris Derin to restore this program.

Great Add-on, instructions for removing date check Rated 5 out of 5 stars

This is a fantastic add-on. Let's congratulate the author and not attack so hard for the occasional glitch. I also cannot use TB at all without TFSC. I've also had the TFSC button disappear, and it turns out this is because of an easily removable date check in the code. The check seems to be trying to ensure that TFSC has been updated within the past 90 days. So if the author goes longer than 90 days before making an update, the button disappears. When this happens, you can fix it yourself by making a trivial modification to the official release - this is preferable to downloading and installing software from an unknown source.

It seems like a recent update has fixed the problem, but it could happen again any time that an update is not issued in 90 days. I took a look at the code in the new update, and the 90 day check is still there.

To fix this yourself without downloading untrusted software:
- download the "xpi" file for the latest TFSC release.
- change the file suffix from xpi to zip
- unpack the zip file into a work directory
- in your work directory there will be a file called "bootstrap.js". In that file, search for a function called "compile:function()". Comment out the line that begins with "if(new Date().getTime()".
- Save your changed bootstrap.js
- zip the contents of your work directory into a new .zip file. Note that you need to zip the contents of the work directory, not the directory itself.
- change the suffix of your new zip file to xpi.
- install your xpi file as a thunderbird add-on.
- set automatic updates to off for your new version

Thanks to the original comment by happyone that had a pointer to the place to fix.

Functionality restored Rated 5 out of 5 stars

Well done Thunderbird Support for restoring this very important functionality - I can read my e-mails once again.

64.1 restores functionality Rated 4 out of 5 stars

I too had lost control of font size etc with prior version of this Add-on and latest TBird. But version 64.1 restores functionality.

Rather than berate the author for his efforts, I would like to thank him for providing crucial functionality for TBird.

Fixed worked but... Rated 2 out of 5 stars

The fixed worked for me but now I can't read my 'account settings' box/feature when the addon is enabled. It looks oversized and will not respond to any mouse clicks. Disabled, the account settings UI looks normal and responds normally. I am wondering why others cannot produce a similar add-on since so many seem to find it indispensable, including myself.

Update - Jan 9, 2018. I fixed the issue of the garbled unreadable ;account settings' UI by uninstalling TB 52.5.2, then installing a older version 24. I didn't like version 24 so I reinstalled version 52 and now the UI problem in gone/fixed.

Would be nice to have Baris Derin write a clear explanation of what is going on and what his plans are for fixing the issue, if possible. :)

Thank you so much for all the help here! Rated 5 out of 5 stars

I am so so grateful for everyone who helped untangle the recent problems - esp Anonymous user e05e1e on Jan. 7, 2018, whose directions this slightly-inept user was able to follow.

I'm so discouraged to see people shouting at and deriding Baris, who's provided a free fix for so many years for this bewildering omission in Thunderbird. I couldn't use Tbird without TFSC; now that there's a problem, the insults are flying. It's sad.

But they seem to be in the minority - yay! - and everyone else has focused on the fix. Thank you so much. You've rescued me from the hell of Mac Mail, which reminded me in less than two days why I hate it so much. Thank you Baris, and thanks all the helpers here!

This is a great add-on! It's a complete shame that FFox Quantum won't support this any more. Thanks for adding a TBird specific version now that FFox Quantum doesnt work with it. Could you make a similar version for Firefox ESR so that we can continue to use it, but not get updates on the version used by FFox Quantum?

roundabout fix for theme font and size changer. Rated 4 out of 5 stars

have messed with this and am going crazy but i have a fix that works for me. was using waterfox with updates disabled but that didnt work as of yesterday with size font and theme changer. so now am using an older version of palemoon where everything seems to work. its version 26.5. i have all updates disabled and using version 43.4 of theme font and size changer. icon is visable and all works correctly. also any downloads work easily with download helper. more recent versions of palemoon do not work correctly with these addons. best of luck to all who need this to see easily. win7 64

war mal gut... Rated 1 out of 5 stars

war mal gut und nützlich, weil man die Fonts größer stellen konnte. Verstehe eigentlich gar nicht, warum TB das nicht standardmäßig in seinen Einstellungen anbietet.
Aber seit dem letzten WIN 10 Update geht's leider gar nicht mehr! Very sad!
Ich sehe bei den Einstellungen nur noch drrei Menüpunkte und die interessieren mich eigentlich nicht! :-((

Running Windows 7.
The fix from Happyone worked... thanks!
[for slow people like me .. the 'add from file' option is in the 'gearwheel' displayed at the top of the Add-ons Manager page in TB]

... "Hello, please do not install other add-ons other than official page. Those may steal your mails and important files from your computer. Uninstall the other add-ons that are not offered by us."

Many thanks for the work you have done that makes TB usable for me. With the TB standard font size it is too hard to read.

I realize installing an add-on from an official source carries the risk you describe. If If TFSC will not run then my other choice is find/install another email client, re-add the email accounts, pull down nearly 100K email headers. The alternative of accepting the risk with the unofficial add-on seemed less painful.

I would not have installed the unofficial add-on if I had seen a developer post acknowledging the problem and saying when a fix might be available but I could not find any information.

I have now uninstalled the add-on from the unofficial source and reinstalled the official version ... and it still does not work with TB 52.5.3 so I am back to the same problem I started with. Please tell me what I need to do to get the official version of TFSC to work.

thanks

I'm using Windows 10 and am legally blind. A few days ago my ability to adjust the font size on Thunderbird disappeared and the font was set the the very small default setting. When I tried to download the new version, I read that it was not available for my platform. WHY NOT????? I need to be able to increase the font. I will probably have to switch to a new e mail system. What is with you guys?

I cannot install it. When I go to the suggested URL for T-Bird users to download, I get a message "this...if...not available for your platform" This is a most frustrating situation. I had everything running along well until about five days ago when Thunderbird reverted to a very tiny font (almost illegible) and I cannot restore my larger font, etc.

Please supply me with a uncorrupted version of the add-on suitable for Windows 7,and Thunderbird 52.5.2.

Thank you

Still trying to get this fixed on my MacBook, running El Capitan 10.11.6. First few tries using HappyOne's link didn't seem to do it. Anybody have step by step assistance for a Mac installation? Thunderbird version 52.5.0.

AHA! Never mind. Got it. Thanks HappyOne.

You're a lifesaver, Happyone! Rated 5 out of 5 stars

Thanks Happyone for making it so easy to solve this problem. I spent a lot of time yesterday trying the unzip/zip change bootstrap solution but I am too unfamiliar with these things and failed.
I confirm what the previous poster said: this great offering by Happyone will not work with TB 58 Beta. But it works like a charm with the previous version 52.5.2
Download the file from the link Happyone provides, then go to your TB 52.5.2, click on the menu (3 lines in top right hand corner, go to add ons, click on the wheel for a drop down menu, choose 'install add on from file' , browse for that file and install. Thanks again.

I found this add-on in 2014 when Thunderbird reduced the size of the theme font. I only use it to change the size to 18.0, which makes the folder list, mail list, and headers comfortable to read on my widescreen desktop. Thanks Baris Derin. And thanks Happyone for providing a working add-on after the original stopped working yesterday. I can see my mail again!

I'm using TB 52.5.2 (32-bit) on Win 7 Pro.
