MT Icons not Dispaying right on Firefox

[BertSP]

Hello,
I have just noticed this strange behavior on an alternate computer at home when viewing my site. It runs Win 10, and has the same upgrades as my main computer. The MTIcons do not display the correct icons. This is only for certain ones and the trouble icons also do not display on certain menus. Anybody had this problem?. The Firefox version is 57.0.2
The site is www.s-p.me.
Season's Greetings to all

Try emptying your browser cache. Tried several times in FF, Opera, Chrome and always everything ok

Its interesting, but it renders the same wrong icons, looking up your site. It works well with Chrome under the same user, and it works well using FF with another user. Cache, cookies, history all purged of course.
I will call the file containing all the MT icons and see what it renders.
No biggy, just strange.

I have uninstalled and reinstalled FF on this machine and same user will not render the MTicons correctly. When bringing up the ..../admin/menu/menuIcons.php page, the MT icons are messed up for 90%. The other font awesome icons below are fine, go figure.

It is strange, but Im unable to replicate the issue myself. I tried another PC now and everything OK again so it makes me think it must be some corrupt local setting on that computer. Re-installing a browser does not help unless you completely delete all profile data

I checked on my FF (Running on Windows 10 Pro), version 57.0.2 as well as 57.0.3 with no icon issues on your website. I agree with Jachym. It's locally on that computer.

What you could do (Last Resort, like Jachym mentioned above) is log on as the local administrator account, navigate to Control Panel, System, Advanced system settings, Under User Profiles, click on the Settings button.

Find that specific user and delete it (BACKUP ALL PERTINENT FILES/FOLDERS FIRST!)

*** NOTE ***

Please make sure to backup all important files/folders/documents beforehand!! I have had similar issues with certain accounts. The only quick way is to start over from scratch (That specific user).

Again, I can't stress that this would be the last resort "Hail Mary". At my work, all user's desktop/document folders are redirected to the server so none of their files/folders are 'lost' after I delete their account.

I've seen this before with Firefox and clearing the cache completely has always resolved it for me.
