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. :-)

This extensions been good for quite some time now, but recently, due to the bug that's been slowing down my browser, it's starting to get unbearable, I upload content on YouTube and browse the internet, and constantly getting a popup from my browser that its being slown down for long periods of time every 5 - 10 minutes is pretty annoying.

Until this bug's fixed, I do not recommend this extension to anyone, despite how good its features are.

I used to enjoy this Add-on until recently. I am using Firefox, and lately I have been getting the error message that Malwarebytes Browser Guard is slowing down my browser and that I should consider removing it. Not good.
