close icons dissapear

Posted

Small x's on tabs and back/forward button seem to disappear after being opened for a while. same as the "star, reload" button, but they are a shadow if you hover your mouse on icons. I haven't modified any settings for mozilla.

Hi,

Please check if this happens in Safe Mode. Safe mode disables the installed Extensions, and themes (Appearance) in Tools (Alt + T) > Add-ons. Hardware acceleration is also temporarily disabled - the manual setting is Tools > Options > Advanced > General > Use hardware acceleration when available. All these settings/options/add-ons can also be individually or collectively disabled/enabled/changed in Firefox normal mode to check if an extension, theme, option or hardware acceleration is causing issues. Disabling/enabling hardware acceleration, and some types of add-ons in normal mode may require a Firefox restart.
