- Bluhell Firewall! If you installed IETab, UnMHT will failed to display the MHT file in your local machine. Please disable following from IETab's site filter.
- I get that in the Firefox web console only when I have the Bluhell Firewall ad-blocker enabled. If you have any ad-blockers running, disable them and check again. Recommended this. Original Poster. Marked this as an answer. Recommended based on info available.
Mozilla’s report prompted me to take a look at Bluhell Firewall, a relatively new, lightweight ad-blocking extension which is quickly gaining a following: All we know the availability of popular AdBlockers lying around but frankly, these are too bloated with several features and options which most of us don’t use beyond the defaults.
Bluehell Firewall is an extremely lightweight ad-blocking and tracking/ privacy protector.
How lightweight? As we write, the current version is a mere 42KB download, a fraction of some of the competition.
One reason for this is that Bluehell Firewall uses only five blocking rules. Apart from simplifying the add-on, it also greatly improves performance, as there are very few checks to make before any web resource can be displayed. Yet it still reportedly blocks about 7,000 .com and .net domains.
Another reason is that Bluehell Firewall's developer has concentrated on the core ad-blocking functionality, and not added any other frills, at all. There are no options or settings, you don't have to set up any subscriptions, it just works. (You don't even have to restart Firefox after Bluehell Firewall's installation.)
Arguably this does go a little too far. The ability to create a whitelist of trusted sites would be welcome, but, well - forget it, at least for now.
Bluehell Firewall scores well for ad-blocking, though, and it's definitely easy to use, so on balance it gets a thumbs up from us.
Version 2.5.0 'updated blocking lists'
Verdict:
Its total lack of configuration options may sometimes be an issue, but Bluehell Firewall does a great job of blocking ads without affecting performance, and that's what counts for us.
It's been awhile since I did one of these Spy vs. Spy posts, but with a couple of new ad blocking extensions on the scene, what better occasion for a good old-fashioned deathmatch? The two new kids on the block are uBlock (now called uBlock Origin, see update at bottom) and Bluhell Firewall, both Firefox extensions with uBlock also available for Chrome and Safari. They'll be taking on the gorilla in the room, Adblock Plus, the ad blocker practically everybody has on their computer. But do they know what lurks beneath?Adblock Plus has had its share of controversies, but one of the main ones has been its performance. It's been accused of slowing the browser launch and being a memory hog, even if it does eliminate more ads than the competition. Bluhell Firewall and uBlock advertise themselves as being significantly lighter on resources, so let's put them to the test and see who's truly worthy.
I'll be testing for browser startup time, RAM usage on startup, and RAM usage with three tabs open (the three being IMDB, OS X Daily, and Gawker). The tests will be done on my Powerbook with TenFourFox 31 running a fresh profile with no other extensions. As a frame of reference, let's start out with no ad blocking:
startup time -- 8.5 seconds
RAM on startup -- 122 MB
RAM with three tabs open -- 265 MB
Those numbers are rough averages after a couple of run-throughs. Since the results were consistent, I didn't bother with more than two. Now let's get to Adblock Plus:
startup time -- 15 seconds
RAM on startup -- 200 MB
RAM with three tabs open -- 375 MB
The startup time includes about five seconds of a spinning beach ball while the ad blocker initializes. As you can see the memory went way up. Now let's see how uBlock does:
startup time -- 8.5 seconds
RAM on startup -- 165 MB
RAM with three tabs open -- 280 MB
No impact on startup time and modest bumps in memory usage. Finally, here's Bluhell Firewall:
startup time -- 8.5 seconds
RAM on startup -- 123 MB
RAM with three tabs open -- 215 MB
If memory is what you're going by, Bluhell is the clear winner. But does that mean it's the best? Its filters not being as extensive as Adblock Plus's, it lets the occasional ad through. It also lacks a whitelist feature, so you can't make exceptions for websites you want to support. Some people also report some site breakage.
In my opinion, uBlock is the more interesting alternative. It supports whitelists and is available on all major browsers. And as far as ad blocking goes, it's no slacker compared to Adblock Plus. In fact, Adblock Plus was overly aggressive, filtering out all of Gawker's 'Promoted by...' posts. Most of those are embedded ads, but some are guest essays that, no matter how pretentious, should never be blocked.
I've always used NoScript combined with CSS rules based on floppymoose (the one shipped with Camino, to be exact) for ad blocking, but it's kind of a pain to edit your UserContent.css to include new rules for ads that get through. UBlock seems the more up-to-date option. In any event, NoScript should remain an essential item in your PowerPC toolbox to keep the Web loading fast and smooth while avoiding javascript catastrophes like this one, or this particular holocaust. I know there are a lot of about:config tweaks out there that promise big speed benefits (pipelining, etc), but they don't deliver much. To enhance the speed of your browser, it's really all about NoScript and a good ad blocker.
(UPDATE: Since the writing of this post, uBlock's original developer has left and begun a fork called uBlock Origin. UBlock will Bluhell Firewall Free

they seem to have stopped development. UBlock Origin has dropped support for Safari, so Safari users should stick with uBlock.)
