tampermonkey VS adblocker

This extension makes use of JS computed property names to perform user specified dynamic actions on user specified elements.

I started working on an extension primarily for my own very specific use case. I knew of Tampermonkey and it's relatives before, but hadn't used it extensively. I also was following the news of MV3, so wasn't sure of their long term viability. But more than anything having recently got into frontend development I also just wanted to build an extension myself, getting to understand the newer limitation and alternatives was just a bonus point.

Literally a couple of days ago I got to know (From HN nonetheless https://news.ycombinator.com/item?id=38526277) that userscripts are going to be allowed in MV3 too, so I finally decided to actually check out ViolentMonkey, which is pretty neat, but from the looks of it would have to migrate to `chrome.userScripts.register` which would eventually require `userScripts` permission and with it would need [developer mode enabled](https://developer.chrome.com/docs/extensions/reference/api/u...). While browsing through the subsequent discussions I saw there were many other alternatives for dynamic script execution, from creating and the dynamic code to `` tags to using `evaljs`, but I wasn't aware of them while building this (see for ex: <a href="https://news.ycombinator.com/item?id=31425256">https://news.ycombinator.com/item?id=31425256</a> and <a href="https://github.com/Tampermonkey/tampermonkey/issues/644#issuecomment-857838249">https://github.com/Tampermonkey/tampermonkey/issues/644#issu...</a>) (and tbf it wan't even my goal to get full JS execution in my extension).<p>Long term my goal was to build a small JSON config for the actions needed and parse and apply them to have the desired behavior. I also was planning on exposing some extension only behavior (like tab functionality) via message passing with service workers (The config could be something like

Do you use "Never Remember History"? There are bug reports about it. Fix is soon to be released.

Yes, I'm having the exact same problem. It was updated on Nov. 30 and I can't find a way to downgrade back to the last version. There's been several issues posted on the tampermonkey github recently but I don't have enough technical knowledge to know if any of those issues applies to this problem. And just like you, I can't even see my scripts to move them to a different script manager.

I have no damn idea why Tampermonkey, which as very best I can tell is closed source <https://github.com/Tampermonkey/tampermonkey/blob/master/REA...>, is on the "blessed" Firefox for Android list when Violentmonkey <https://github.com/violentmonkey/violentmonkey#readme> is MIT, although I readily admit doesn't it have a "politically correct" name

I use it a lot and it used to be on github until version 2.9. I guess I could use that but wondering if there are some other nice selfhosted versions where I can easily modify my Chrome webpages that I should consider.

I want to chime on that as it's worth noting that Tampermonkey is no longer open source. I mean it's like that for years - its GitHub repo clearly stands it's just an archive version and commits there date back to 2018. Here's one of the first posts when author went proprietary license and started gaining data (with his comment btw) and technically there's also Security section in FAQ and full Privacy Policy. Also FWIK website is the only place you get info about changes - highlighting that to stop looking for insights on GitHub.

If you can't the answers you're looking for in the Tampermonkey FAQ, you can ask them in the official Tampermonkey support forum.

Tampermonkey devs have implemented it but didn't release it yet and Violentmonkey devs don't want to implement it, so I guess I'm not fixing this issue anytime soon.

Specific case: uBlock Origin seems to block TamperMonkey from either injecting or running my userscript. (See https://github.com/Tampermonkey/tampermonkey/issues/1709 ) I was thinking it might be one of the above rules but I can't really get much out of the logger, and trying to disable those rules doesn't work. Does anyone have an idea on how to progress?

this says GPL so unless they update their license file here, this stays

No well-known content blocker "process about 90,000 regexps" to find out whether a resource needs to be blocked or not, that's just not how it works internally.

Last time I ran benchmarks of all well-known content blockers using Ghostery's benchmark tool[1], all of them could process a network request under 20µs on average.

Some do have performance concerns, but it has nothing to do with network filtering, it has to do with other stuff they do beyond network filtering (for example see [2]) and declarativeNetRequest does not help there, so they will still suffer these performance issues under MV3.

Only benchmarking can tell, we shouldn't make assumption about this. Currently the only comparative benchmark which I know of is ghostery/adblocker and running it with the latest static filtering engines shows uBO performing better:

With that in mind, uBO's blocking engine is currently the fastest as demonstrated by latest Cliqz's benchmarks, so the "quicker" claim does not hold either.

Author of RSS Guard here. After considering many approaches, I managed to dump old C++-based slow adblocking mechanism from RSS Guard and replaced it with this.
