Hii, fahill

it is very common issue!

You can try to disable hardware acceleration in your browser .

Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available" You need to close and restart Firefox after toggling this setting.

if your problem is solved please let me know . Thanks -Arman

The link you sent said "Page Not Found." I went to general settings and unchecked performance and acceleration hardware and that did not work. In previous versions of FF, I could use the mouse over on biblical scriptures and the entire highlighted scripture would show up in my program "Instaverse" with no problems.

How can we reproduce this issue?
