MASSIVE Memory Leak. It consumed 130 gigs of total storage, bloating my pagefile to 96 gigs total.

Does the job, helped me avoid spoilers on a recent release, it blocks the specified word completely, but not only that, it also blocks the entire section such as a whole paragraph or even the whole page, anything linked to the keyword gets blocked, images too, amazing.

Everything works fine, but doesn't block youtube thumbnails

I am trying to avoid leaked content for The Owl House Season 3 and this extension has been working just fine so far.

Used to work just fine, but does not do anything at all now. The settings are missing almost all descriptions for input fields and nothing you enter is retained, so it's impossible to configure spoilers. I tried a few combinations, none of them blocked anything.

Works as intended but can slow down or even freeze your browser :(

This extension works very well if you use it properly.
Works great on twitter, reddit, and general browsing where spoilers are abundant.
Many of the complaints stem from its use on websites like youtube which are CPU heavy, but those can be whitelisted using the tag "youtube*" in the whitelist section.
If you still need spoilers blocked on youtube I use BlockTube, which works very well too.

DO NOT INSTALL. Extension works but it's so old, out of date that slow down browser, even frozen, tax a lot of CPU.

Slows down my browser considerably

It spoiled my favorite show

Slows services substantially. Unoptimized.

Pages became too slow after installing this extension.

Works pretty good so far, but it caused YouTube to become awfully slow and unresponsive. Which is a bummer because YouTube happens to be one of the most spoiler-prone websites.

This issue apparently is remained unresolved for at least a year now, I do hope this can be fixed ASAP. :)

Update: The slowdown is getting worse and even occur on sites like reddit as of today. Unfortunately this extension has to be disabled for this browser atm. It just sucks that the dev didnt bother doing anything about it.

Horrible. Installed for a week, when enabled I had the cpu at 100%, fan at full speed and Firefox was incredibly slow, almost unusable. It all seemed like I had a PC from the early 90s.
Once I disabled 'Spoiler Protection 2.0', cpu and fans were slowly going back to normal.

Really good for many pages, and good customization and clear markups. BUT, it works really poorly on some pages, that some might use a lot. Like YouTube. Youtube gets very unresponsive, loading takes way longer and everything bugs down. The moment I disable the plugin, it work great again. If I turn it on, it gets really bad again. Which is unfortunate. It means I will have to look for another plugin. So I can't sadly rate it higher than this. As it's practically unusable for me. Though it's not a zero, as it shows promise.

EDIT: I have to change the score.. the performace is really horrible and I have found myself running with the plugin activated for 90% of the time, which misses the while point of the plugin.
The strange thing is that even with all special YouTube processing turned off, and NO FILTERS on, the performance is still horrible. All YouTube videos buffers a ton and run at worst resolutions, and the whole browser window is often completely unresponsive.
I will have to uninstall and find another plugin.

Works great, but some websites slow down immensely to the point of unusable

Haven't experienced any slow downs on Pentium G4560, 4gb ram. Works great! Though for example here: https://i.imgur.com/momIpFy.png it breaks the layout (there should be 2 lines filled fully, but the red div seems to be a pixel or 2 too wide). Otherwise everything's working as it should.

Rated 5* for my experience on Google, I'm hoping the creator can tell me how this works on Firefox, because so far I've been able to install it and that's it . . . there's no way to access the options and the app from the Firefox Browser, and it's logo does no appear alongside other apps in the browser bar.

Please help!

I know you're working on performance issues, and it's great because as of now it's nearly unusable on many sites (mostly the dynamic ones, that get very slow while loading content, and after to much content has been loaded). A temporary workaround could be to allow disabling the add-on on user specified websites. Not sure if the "White list" feature is supposed to do that but it's not working on my side. Keep up the good work :)

Such a good add-on! I wish I could donate to the creator(s) of this! So useful. Works all the time! Haven't experienced bugs or problems at all.
