I will describe how to add an invocation parameter for Firefox, which I use, and you can adapt the procedure to Chrome. This involves editing the registry, so take first all due precautions, including creating a system restore point.
Open regedit, and search forHKEY_CLASSES_ROOT\.htm
and HKEY_CLASSES_ROOT\.html
. Click on both, and you will see a (Default)
entry, which for Firefox contains the value FirefoxHTML
.
Now position yourself on HKEY_CLASSES_ROOT\FirefoxHTML\shell\open\command
. The (Default)
entry contains the Firefox command invocation. Modify it to include the additional parameter (-disable-webgl
in your case).
This should have instant effect, but you might possibly need to logout and login.
EDIT
Other registry keys to verify that they use the same handler (FirefoxHTML) are:
HKEY_CLASSES_ROOT\.shtml
HKEY_CLASSES_ROOT\.xht
HKEY_CLASSES_ROOT\.xhtm
HKEY_CLASSES_ROOT\.xhtml
HKEY_CLASSES_ROOT\HTTP\shell\open\command
HKEY_CLASSES_ROOT\https\shell\open\command
HKEY_CLASSES_ROOT\ftp\shell\open\command
