I would prefer to give this 0 stars, but I guess it does deserve ONE because it has detected and stopped a few redirects that were legitimately pages I would not want to go to, and caught some fake sites that were sponsored pages in Google search.

That said, it uses way too much memory for this kind of browser extension, which I could forgive considering that I have plenty of RAM, but where I draw the line is the absolutely irritating pop-ups FROM the extension itself!

If I'm using an add-on that is supposed to do things like block ads, why on earth am I constantly getting them from the add-on I'm using to block them?

Why is it EVERY day, when I go to use Firefox, I have to see some annoying ad telling me how many things the Malwarebytes Browser Guard blocked? Like you need to sell me the extension I already have installed on my computer!

And worse, there's NO WAY to turn them off! Go through the settings and there's no setting to control the extension notifications, so I have no choice but to see them, which while that's bad enough, even worse is they never want to close! Sometimes clicking on the X won't even close it, so I end up either refreshing the page or having to duplicate the tab and close the one I'm on because a ridiculous pop-up from my pop-up blocker won't go away!

Now, sometimes I'm getting multiple of them! Like I finally get it to close and there's another one, I just got two pop-ups from Malwarebytes Browser Guard in a ROW!

I've finally had it, I'm uninstalling this thing because I'm sick of it. I didn't install a pop-up blocker so that I could have to constantly have unclosable pop-ups from the blocker, that is absolutely absurd and crosses a line for me.

A good browser guard would just have the icon for it maybe have a number over it or a quiet tick when it blocks something, and that's it. Whoever decided there should be pop-ups for the browser guard I already have installed should not have that job. Show me discretely that you block stuff, I don't actually care how much stuff you've blocked for everyone in the world every day, like not even a little bit, as in there is no reasonable way I could possibly care less, so I don't want this information, and should not be forced to see it constantly.

I would never recommend this to anyone as it is unreasonable that the extension itself spams the exact thing I got the extension to stop.

Note: After posting this review and uninstalling the plugin, the exact page I was on and had just closed all the pop-ups, had another Malwarebytes Guard Popup telling me how many things Malwarebytes Guard removed in the past 30 days (in general for everyone, nothing to do with me). It actually happens all the time when I move between tabs, often forcing me to try and close the thing dozens and dozens of times every day. I'm so glad I uninstalled this thing, I despise it, and I will never install it again. At this point I don't even care if there is some way to disable this somewhere (not that I could find one), I'm beyond irritated that this is actually the default behavior. Malwarebytes (even the AV) used to be such a lean and non-intrusive application. Now, it's basically junkware, like the garbage bloatware I used to charge people to remove from their new computers. I've seriously gone from being a loyal Malwarebytes fan that has recommended and installed this software for thousands of customers, to someone who really can't stand it. I don't know why they have ruined what used to be hands down the best anti-malware software in the world, but it is an unfortunate loss.

If you need a extension to stop pop-up ads, scams, etc., I would suggest looking elsewhere, this thing is exactly what you're probably trying to stop when you install it.

WAYYYYYYYYY too much ram usage get on work and notify me on email if you have fixed it

It's an essential extension for me. I would not surf the Internet without it anymore. It keeps me safe from all kinds of threats on the Net and even gets rid of most of the annoying ads you come across. Highly recommended!

Currently causes browser to load sites very slowly or not at all. To load faster I disable the ad blocker in Browser Guard. Please fix.

Something has changed recently that causes Firefox to slow to a crawl when this is enabled. CPU and memory utilization look normal. Even local web pages that normally load in milliseconds now take seconds to load, and often as much as 30 seconds for a normal page load.
This is badly broken! Disabled.

I've used this for years but had to uninstall it because I couldn't copy 50% of what I needed. Half the time I tried to copy something I'd get the pop up that was a warning that something had been copied, and when I clicked "disable for this website" it did nothing. No matter what when I pasted the content it would just say "[suspicious content]."

This was a great extension before the clipboard monitoring feature was introduced. This feature does not work properly and constantly replaces the clipboard content with “[⚠️ Suspicious Content]”.

Please provide the option to disable the feature because the extension has become unusable. I also tried disabling the “Get data from the clipboard” and “Input data to the clipboard” permissions from the Firefox settings, but it doesn't work. This is a serious problem.

I also tried sending an email to support@malwarebytes.com, which is listed in the extension support, but I received an automatic reply saying, “Your email was sent to an unmonitored mailbox account.” and to open a ticket.

Normally works very well, unfortunately even after the mid July patch it was still making watching Youtube incredibly sluggish and with pop ups so I've had to temporarily disable it.

Hagezi TIF better than this extension. Many Github links are incorrectly marked as malware. Useless continue button

It's great i actually only run MBBG these days but its certainly got some slowdown issues happening at the moment, I look forward to the next update as even on pages i have whitelisted get bogged down.

Excellent add-on for safer browsing, without all the annoying bloat that other AV-providers implement in similar products.

I'm running the latest version of FireFox. This has warned me about entering two or three potentially malicious sites, but I get multiple occurences daily of pages virtually freezing and a warning pop-up that the plugin is slowing FF down. I've therefore disabled it for now. When I next remember, I'll give it another try to see if the issue (if there is one) has been addressed.

Edit: VERY impressed by the speed of Malwarebytes' response! Have added a diary reminder to turn it back on in a week's time to see if the fix has been implemented. In the meantime, I'll try very hard not to visit sites I shouldn't. :-)
