Unwanted red border in Google Chrome 46.0.2490.80 (64-bit) around codePosted on


Some days before I noticed red border on any site on the web in different places. I suppose it appears around <table> content. For example look at attached screenshot of this site’s bottom.

How can I get rid of red borders?

Those red borders are often used by web developers. There are some Add-Ons (in Chrome as well as in Firefox) which provide them.

To disable them, go into your browser add-ons and uninstall/disable them. Some addons(like the well known “Web-Developer” Addon) let you enable/disable the border on the fly. Check the “contour” or “border” settings and disable the respective option.

Turn off hardware acceleration in Chrome. Settings > Advanced > Use hardware acceleration when available or just type chrome://settings/system to get required screen. Thanksenter image description here
