You can also change the settings for different extensions. Once you’ve found the extension you are looking at it, click on it and select your preferred action. If there is an extension you want to enable, disable, or uninstall, just find it from the link of add-ons in the Manage Extensions menu. In the Opera menu, select “Extensions,” then click “Manage Extensions.” This action will open a new menu where you can view your extensions and make changes to them. Once you have installed your Opera extensions, you can get to actually managing them.
Go through the catalog and choose a few extensions to install. This link will take you to the Opera extensions catalog, where you can download a range of different add-ons for your browser. Soon enough, users of Opera 9.50 are going to be visiting this site and, unlike in the past, they are going to assume that the formulæ they see are being rendered as intended.On your computer, launch the Opera browser and type /en/extensions into your navigation bar. But those’ll have to wait for some other post, as I’m nearly out of rant.
I have plenty of other complaints about the proposed CSS-compatible Profile. Consider the itex command, $$\tensor$), for instance, are apparently too “ marginal” to even be worthy of this ASCII Art treatment.Ĭhaals, the erstwhile accessibility guru, must be undergoing some serious cognitive dissonance. the use of SVG background images), there are many things which simply don’t work.

Neither Safari nor Opera supports MathML, but I haven’t felt the need to go to extreme lengths to warn users of those browsers that their rendering of the equations hereabouts are broken. I guess this says something about user expectations. No, he insisted, he was using the latest version of Internet Explorer, and it was rendering my site just fine. I suggested to him that, perhaps, the reason he thought my derivation was erroneous was that the formulæ were not rendering correctly in his browser. We went back and forth, for a bit, with me explaining what I was doing, and he insisting that I was clearly wrong.Įventually it dawned on me that my correspondent was an Internet Explorer user who, despite the repeated warnings presented to IE users, had not installed the MathPlayer plugin. My correspondent complained that I had made several boneheaded mathematical errors in my post. Several months ago, I got an email about my “elementary” derivation of Boltzmann Entropy.
