And now it’s Opera’s turn

In a recent post, I lauded the new release of Firefox, known as Firefox Quantum, or Firefox 57.0 if you’re in to numbers. The release introduced new features and fixed many issues that have plagued it, in some cases, for years (memory leaks, I’m looking at you). One of the things I really appreciated was the ability to take a full-page screenshot that would capture the whole page, regardless of how much of it was off-screen. For someone like me who uses screenshots in class and on this blog frequently, it’s a godsend.

Having said all that, I also mentioned right at the beginning of that linked post that I’m an Opera guy even though the new Firefox has really narrowed the gap, and since Opera just released version 50.0 with some features of note, I thought it would be only prudent to mention a couple of them here. It won’t get the same coverage as Firefox because it’s not as significant of an upgrade.

Indeed, I’m only going to mention a couple of its features: full-page PDF capture and anti-Bitcoin mining technology.

As I mentioned, Firefox allows for a full-page screencap of a webpage, even if you can’t see it all in the browser window, and the cap is then saved as a .jpg image. As I mentioned, since I use screenshots extensively in my classes and on this very site, that’s invaluable. Now, Opera has the ability to do the same thing except it captures the page as a pdf. It works perfectly, I’ve had no trouble at all, and I can see how it would be useful, especially as opposed to a .jpg. If you wanted a hardcopy version of a recipe, or a series of lessons, or set of instructions then it’s ideal. If you wanted to have a permanent copy of a webpage, or send a copy of it that could be used at a meeting or for whatever reason can’t send a link then it would be very useful there as well, as it would certainly be easier to read then an image. I’m quite impressed with its functionality, and it offers a nice other option alongside Firefox’s full-page .jpg image capture. Both options are fantastic, work flawlessly, and definitely have their own specific use cases. The image below shows a multiple-page post from this site that was saved as a pdf and how it appears; it’s exactly like reading the site itself, but without links. I should also add that Firefox has an advanced ability to select page regions for capture and editing features, a feature not shared by Opera.

The other interesting feature Opera has developed is anti-Bitcoin mining technology. Bitcoins are obviously all the rage, and whether that’s because of the nature of buzzwords or legitimate hype, mining them (a topic far beyond the scope of this post but you can read about at this obvious site) requires extensive use of a PCs resources, somewhere in the neighborhood of one hundred percent, and while smart people will simply build dedicated machines for the task, other smart but misguided people instead want to use yours, and will hijack it through scripts to do so. The obvious downside is that your machine will slow to a crawl and use up insane amounts of power while it tries to mine Bitcoin for someone else. Never fear though, Opera to the rescue. According to their blog, simply turning on their built-in adblocker – another nice feature by the way along with their built-in VPN – will prevent drive-by Bitcoin-mining hijackers.

By the way, I say Bitcoin as a proprietary eponym, like Q-tip or Kleenex, however it’s any type of cryptocurrency mining that gets blocked, and Bitcoin is hardly the only one out there. I should just start saying cryptocurrency as it’s the better, general term, and I’m sure someday I will. Just know that there are many viable brands of this digital currency, but that’s a post for a later time.

So the eternal tug-of-war between Opera and Firefox continues, at least for me, and I couldn’t be happier. I’m thrilled at the way they’ve developed and hope they both keep pushing browsers forward.
