Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

Suggest work on your Video Card Drivers as most of it is errors that allow you to see stuff : featureLog: {u'fallbacks': [], u'features': [{u'status': u'blocked', u'description': u'Compositing', u'log': [{u'status': u'blocked', u'message': u'Acceleration blocked by platform', u'type': u'default'}], u'name': u'HW_COMPOSITING'}, {u'status': u'unavailable', u'description': u'OpenGL Compositing', u'log': [{u'status': u'unavailable', u'message': u'Hardware compositing is disabled',

Changing the zoom control had no effect on text on top of text. I've already tried the other suggestions about cookies/cache/safe mode/disable hardware acceleration.

Pkshadow, I have no idea what your post means. I'm using latest nvidia drivers with my nvidia card.

Other browsers like Safari and Chrome do not have the problem of text on top of text.

It explains itself :

u'blocked' = BAD u'Acceleration blocked by platform = Bad or Card can not do Hardware Acceleration u'OpenGL u'unavailable = a wack of drivers https://en.wikipedia.org/wiki/OpenGL https://www.khronos.org/opengl/

• Uninstall and Reinstall your Drivers

Just because other browsers can do something does not mean that that is ok. Most other browsers have less adherence to W3C.org rules for making web pages and for Browsers displaying them.

Try a Refresh after have fixed the drivers : Refresh but Note that this does more than uninstalling and re-installing does. Normal uninstalling does not remove some preferences which may have become corrupt. Please Refresh but do this 1st:

• https://support.mozilla.org/en-US/kb/export-firefox-bookmarks-to-backup-or-transfer
• https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

I'm using openSUSE Tumbleweed which is a rolling release. The kernel is updated 3-4 times a week which means I have to compile and reinstall the nvidia drivers after every kernel update. I use Firefox Sync if I need to reinstall my OS, which restores most of my settings and my bookmarks. I don't see the point of backing up my bookmarks or creating a new profile folder just because some web pages don't render correctly when I use Sync.

I messed up the quotes above but I hope you get the gist.

Sync does not replace :

So I guess your stuck with that then for a few weeks.

This can happen if you block a special icon font file and Firefox is showing the ALT text instead.

You can check the Web Console (Tools -> Web Developer) for messages about blocked content and about the presence of mixed or unsafe content.

• https://developer.mozilla.org/en/Tools/Web_Console

You can check the Network Monitor to see if content is blocked or otherwise fails to load.

• https://developer.mozilla.org/en/Tools/Network_Monitor

If necessary use "Ctrl+F5" or "Ctrl+Shift+R" (Mac: Command+Shift+R) to reload the page and bypass the cache to generate a fresh log.

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block (wanted) content (Adblock Plus, NoScript, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block (wanted) content.

• make sure your extensions and filters are updated to the latest version

Firefox shows the shield icon at the left end of the location/address bar in case content is blocked by Tracking Protection.

• click the shield icon for more detail and possibly disable the protection
• You can check the Web Console by Tracking Protection
• "3-bar" menu button or Tools -> Web Developer

I checked "allow pages to choose their own fonts" and that fixed it. Thanks for the help.
