The description promised I'd be "able to see and control what [JavaScript code] happens."
Naïvely, I assumed it'd give me a sensible list of scripts that have run on the webpage, in chronological order.
And broken up into blocks, or in tree format.
With checkboxes to block the script from running again.
Then I could block half the scripts, see if that worked, then block some in the other half if necessary.
And thus catch the offending script (- that kept putting a cursor in the Search Box every time an article loaded on the website I go to, and every time I came back to the page after tabbing away; this caused the mobile keyboard to open, and cover half of my screen. Even when I was looking at the list of tabs, for heaven's sake.)
I thought Luminous would make the job easy. As if.
It gave me three separate lists, titled "Web APIs", "triggered events (handleEvent)", and "attached events (addEventListener)".
What is that supposed to mean?
They seemed to be hierarchical, but I couldn't tell for sure.
The items in each list didn't seem to be in any particular order at all – and if there was a pattern, the program wasn't about to tell me.
In theory, you tap on an entry in the list to block it from executing again.
In practice, one of three things happened:
- the entry changes colour, but nothing else.
- a popup appears, showing script code.
- the item does toggle from being allowed, to blocked. And every time it does, an annoying, blinding white overlay appears for a few seconds.
And there were many dozens of entries in "attached events", all of which I had to toggle. It might take four or six tries for each item, depending on the program's mood.
Every time I blocked some, the number of items in the list kept changing.
The items that disappeared, weren't crossed out, didn't leave a placeholder - they vanished completely, and I couldn't make head or tail of the new list.
- Even if the entries did stay the same, their order kept changing.
- Some of the items in "triggered events" and "attached events" were the same.
- The extension's tab kept closing on its own, without my permission, whenever I switched to a different tab. And then I'd have to open it again every time.
The logger was unreliable too, sometimes giving 'nothing detected so far' under the "attached events (addEventListener)" heading, after a page reload. Yes, after the page has fully loaded. It would take another reload to make anything show up.
After two hours of this, I managed to narrow it down to two scripts – in the higher-level "triggered events" list.
It probably was just one script in the end, but if I tried to find the actual offender, in the shifting, massive "attached events" list, I'd have gone nuts.
And now I'll have to do that anyway, because it turns out that blocking those two scripts (blocking either one of them isn't enough) breaks the site's search function.
This interface is just RAAAAAAAAAAAAW. This is an extension for Java programmers to use, basically.

- Rated 5 out of 5by Gihan, 4 months agoIt was bit hard to understand the logic how it works but once you do its a great tool
so when you visit a webpage it will auto apply the 'default' setting. don't change the default (Global).
instead add add a 'website rule' (inherited child) and add customization to it. Then the rule will apply only to that website while others remain unaffected.
Udemy now always show the video controls on full screen unless the mouse is on the same screen. This add-on help to customize that so the annoying menu and control remains minimized when the mouse is on another screen so you can practice while watching. - Rated 5 out of 5by Firegorilla, 2 years ago

- Rated 5 out of 5by Firefox user 15268231, 5 years agoI did hesitated while rating this extension. After all, i gave 5/5. Why so?
I feel lack of selectiveness, like 'disable [list,of,events] for this.css.selector', once hidden sidebar shows only after disabling and reenabling extension.
On the other hand, i am aware of how deep JS goes into websites and i know it's not trivial to make it perfect.
Ultimately - in my opinion using JS injection to fight JS events is somewhat grotesque and leads to race conditions. There should be in-browser mechanism to actually ALLOW event to be bound to specific element.
After all - idea of this extension is something that should be picked up by Mozilla and incorporated into their products, even as paid option. Definetely 10 out of 5 stars from me. - Rated 3 out of 5by ᴋɪʀᴀ ꜱᴍɪᴛʜ, 5 years ago

- Rated 1 out of 5by Stin, 5 years agoSearched for 'Script Block'; Found this; Added it to FF; FF froze completely at >90% usage on 5 parent threads; FF completely unresponsive; Had to force-quit FF and restart; Removed said pain in the derriere. Reported for poor quality.

posted 5 years agoThanks for your review!
Development of the extension continues and a new version has been released today (0.0.28) adding requestAmimationFrame detection. - Rated 5 out of 5by Viktor, 5 years agoВсе дуже гарно зроблено, Працює прекрасно, робить все що треба!
- Rated 1 out of 5by Anonymous, 5 years agoNo way to set it to work purely as a blacklist. It breaks too many websites and I don't want to whitelist every single one of them, I'd rather just blacklist the shady ones.
- Rated 5 out of 5by DeronLJ, 5 years agoVery powerful extension for advanced users for monitoring and selectively blocking Javascript.
- Rated 5 out of 5by Firefox user 15138303, 5 years agoTHE extension to use for defending against session recording, the extremely invasive and unethical method of analytics! It won't block the session recording script, but it will prevent most of the session recording data from being sent.

- Rated 4 out of 5by Firefox user 11410084, 6 years agoMuy buena en chaosimg.site te cuida muy bien pero falla en pixhost.to y imagetwist.com no detecta el JS/ExoClick.A y en la pagina convert2mp3.net no detecta JS/Adware.Agent.AA
( JS/ExoClick.A )(JS/Adware.Agent.AA) - Rated 3 out of 5by puckface, 7 years agogreat addon, however it has one flaw, and that is that it uses not a lot of cpu power but a fair bit. with idle firefox and luminous enabled i can observe the cpu usage for firefox go up, not a lot but a fair bit. i disable lumoinus and idle firefox uses almost no cpu. enable lumious again and idle firefox uses cpu. this leads to a bit of choppy scrolling as well. this is on solus 3(linux) firefox 58.0.2 64 bit

posted 7 years agoHi puckface, thanks for the review! The new version 0.0.23 is available and has considerable performance improvements. In addition, I have created special configurations to be able to turn off features that can affect CPU usage. If you want to know more details or to comment on the problems mentioned above, please see the link: https://github.com/gbaptista/luminous/issues/78 - Rated 5 out of 5by rudecoyote, 7 years agoWow! this works great for me, needed to block a script, but not all the scripts as most other plugins do, could see what was working and not, site kept blocking me because of my ad blocker, boy did I fix that with this plugin and I'm a novice, so someone with a little more knowledge than me I'm sure could work wonders , now I'm going to try on other sites that like to play games with scripts, Great work so far.

posted 7 years agoOi Real McCoy, muito obrigado pela sugestão. Não tenho planos de realizar o bloqueio de anúncios no curto prazo, mas recomendo este excelente add-on para este propósito: https://addons.mozilla.org/pt-BR/firefox/addon/ublock-origin - Rated 5 out of 5by jawz101, 7 years agoI don't know what this does, exactly, but I'm sure I like it.
