Text disapearing

This morning i was adding texts to my ''object'' layer and it just made them insible , still therre but you can't see it.
my players say that they see it. It seems to be only me that can't see them, i am confused.
(pen,token,boxes,etc) work just fine as well only texte seems to be the problem.

There is Dynamic lighting, GM layer, Token layer, Map layer so can you state which one is your object layer?

the objects & token layers , and i tested , it is invisible on all layers as well

And in my Google chrome it is working but not in my mozzila firefox for some reasons.

Hmmm. One final question before we launch into the troubleshooting guide. Can you select your text while in the text mode and check the text color? You might have put it on transparency but I don't think so due to your stating the others see the text fine and it is seen fine in the Chrome browser.

After checking and it is not transparent, let's run through the troubleshooting guide while you are using Firefox. Can you please follow Steps 1-3 of our Solving Technical Issues wiki page, taking special care to temporarily disable all browser add-ons and extensions, temporarily pause your anti-virus, and try switching browsers (for Chrome/Firefox specific issues) to see if one of those components is causing the problem. If all of that fails, please follow Step 4, including providing all of the necessary information, so that we can further assist you.

It seem to work for now after i disabled some thing in mozzila but if i encounter the issue again i will do a full report for sure , thx for the assist sir
