Title: Mac Firefox problems Last modified: August 18, 2016 --- # Mac Firefox problems * [barryrueger](https://wordpress.org/support/users/barryrueger/) * (@barryrueger) * [20 years, 5 months ago](https://wordpress.org/support/topic/mac-firefox-problems/) * Attempts to find an answer via search have failed, so here goes. * 1) The text displayed in Firefox on my new Powerbook is all messed up. Looks fine in Safari and of course in IE and FF on my PC. Blog: [threequirrels.com](http://www.threesquirrels.com). * In particular there seems to be a problem with the way that links are displayed. It looks as if the space before a linked word is deleted so that it backspaces up against the preceding text. * For instance, right below this text input box I see the phrase: * (called [tags](http://wordpress.org/tags/)) * In my Firefox browser it renders as * (called[tags](http://wordpress.org/tags/)) * with no space after “called.” * 2) In Firefox on the Mac the text entry boxes in WordPress exhibit very, very strange behaviour, with characters overwriting each other, backspace not removing characters when deleted, and generally making it impossible to compose items. * Again, this seems to work fine in Safari. * I’m brand new on the Mac, and am having enough trouble sorting out more critical issues, so am hoping to find someone who can give mea quick heads up to solve these. * Note: All software is the latest version, except WP, which I plan to upgrade to verson 2 this week. * Thanks, * Barry Viewing 6 replies - 1 through 6 (of 6 total) * Thread Starter [barryrueger](https://wordpress.org/support/users/barryrueger/) * (@barryrueger) * [20 years, 5 months ago](https://wordpress.org/support/topic/mac-firefox-problems/#post-305910) * I just oposted this over at the Firefox site: * Very interesting this one and I’ve found nothing on it. I’ve also [posted it ](http://wordpress.org/support/topic/53858) to the WordPress site. * . It works dandy on Windows FF, Opera, and IE, and on Safari on the Mac, but not Firefox on the same Powerbook g4. * Symptoms (pix at [http://www.community-media.com/wp_firefox.html](http://www.community-media.com/wp_firefox.html)) * 1) The text displayed in Firefox on my new Powerbook is all messed up.

There seemed to be no way to make it “stick”. I would disable ALL of the User fonts, and Firefox would work again, but after rebooting the problem came back. * I also tried deleting the font cache, as described here: [http://www.thexlab.com/faqs/undofontbook.html](http://www.thexlab.com/faqs/undofontbook.html) * 1) Startup in Safe Mode. 2) Log in to your account. This will result in your current font cache being moved to the Trash. Only System fonts are available in Safe Mode. 3) Log out of your account. 4) Restart your Mac normally, i.e. do not restart in Safe Mode. 5) Log in to your account. 6) All previously-disabled fonts will be enabled and load. If you’ve installed hundreds or thousands of fonts, many of which had been disabled with Font Book, this could result in very slow performance of your Mac until all previously-disabled fonts are again disabled. 7) Empty the Trash. * Finally I opted for the brute force method and tracked down which of the three or four font directories held the user fonts: * Users/barryrueger/Library/Fonts * I then deleted ALL fonts from that directory and it seems that it fixed the problem. * My best guess is that some of the fonts from my old windows machine that were copied over/installed to the mac somehow didn’t work. I foolishly assumed that OS X would only let me install what worked, but I was wrong. * Thread Starter [barryrueger](https://wordpress.org/support/users/barryrueger/) * (@barryrueger) * [20 years, 5 months ago](https://wordpress.org/support/topic/mac-firefox-problems/#post-306312) * Further note, yes, I had validated all of the fonts and disabled or deleted those which OS X said had problems. * [eighteentee](https://wordpress.org/support/users/eighteentee/) * (@eighteentee) * [19 years, 10 months ago](https://wordpress.org/support/topic/mac-firefox-problems/#post-306510) * Found your post after lots and lots of searching. I have exactly the same problem– except I have followed every step you have and it’s still there! * Any ideas? * [jwbjerk](https://wordpress.org/support/users/jwbjerk/) * (@jwbjerk) * [19 years, 10 months ago](https://wordpress.org/support/topic/mac-firefox-problems/#post-306511) * font explorer: [http://www.linotype.com/fontexplorerX](http://www.linotype.com/fontexplorerX) ( free) should work better for managing and investigating duplicate fonts. It’s a great program all around.
