Ask HN: Share Your Favorite Bookmarklets

  Oh it's nice to see productivity ones. I mostly use bookmarklets on my phone to fix annoyances bc on a desktop browser you can just open the js console or inspector.

  I beefed up the 'kill sticky' one <https://news.ycombinator.com/item?id=32998091> but that's not very interesting. Here are some other ones:

  * Re-enable zoom on iPhone (for pages that disable it)

      javascript:document.querySelector('meta%5Bname=viewport%5D').setAttribute('content','width=device-width,initial-scale=1.0,maximum-scale=10.0,user-scalable=1');
  

  * Open same page in new tab with js script tags removed (you must click to allow it to open a new tab)

      javascript:(window.openPageWithoutScripts=async%20function()%7Bconst%20resp=await%20fetch(window.location.href);const%20text=await%20resp.text();const%20doc=new%20DOMParser().parseFromString(text,'text%2Fhtml');doc.querySelectorAll('script').forEach(script=%3Escript.remove());const%20w=window.open();w.document.head.innerHTML=doc.head.innerHTML;w.document.body.innerHTML=doc.body.innerHTML;%7D)(); 
  

  * Show page source

      javascript:(function()%7Bvar%20a=window.open('about:blank').document;a.write('%3C!DOCTYPE%20html%3E%3Chtml%3E%3Chead%3E%3Ctitle%3ESource%20of%20'+location.href+'%3C/title%3E%3Cmeta%20name=%22viewport%22%20content=%22width=device-width%22%20/%3E%3C/head%3E%3Cbody%3E%3C/body%3E%3C/html%3E');a.close();var%20b=a.body.appendChild(a.createElement('pre'));b.style.overflow='auto';b.style.whiteSpace='pre-wrap';b.appendChild(a.createTextNode(document.documentElement.innerHTML))%7D)();
  

  * Re-enable long-press context menu (for pages that disable it)

      javascript:(function()%7Bdocument.oncontextmenu=null;window.oncontextmenu=null;%7D)();
  

  * Re-enable text selection (for pages that disable it)

      javascript:(function()%7B;document.onselectstart=null;document.onselectchange=null;document.ondragstart=null;document.onmousedown=null;window.ontouchstart=null;window.ontouchend=null;%7D)();

  As a Reddit user I'm using this simple replace function to switch to the old.reddit.com version of a page:

  javascript:(function(){ if (location.hostname === "www.reddit.com") { location.href = location.href.replace("www.reddit.com", "old.reddit.com"); }})();

  Necessary due to Google search results on Reddit leading to the new.reddit.com version of a page which demands a login more often than not.

  I hate sticky and fixed page headers, so these two are handy:

  Convert fixed position to absolute:

      javascript:(function(){var%20i,%20elements=document.querySelectorAll('body%20*');for%20(i=0;%20i<elements.length;%20i++)%20{if%20(getComputedStyle(elements[i]).position%20==='fixed'){elements[i].style.position='absolute';}}})();
  

  Convert sticky position to absolute:

      javascript:(function(){var%20i,%20elements=document.querySelectorAll('body%20*');for%20(i=0;%20i<elements.length;%20i++)%20{if%20(getComputedStyle(elements[i]).position%20==='sticky'){elements[i].style.position='absolute';}}})();
  

  Though looking at them now I should combine and update them.

  Scroll to bottom:

     javascript:(function(){window.scrollTo({top:document.body.scrollHeight,behavior:'smooth'});})();
  

  Scroll to bottom x 10:

      javascript:(function(){%20let%20count%20=%200;%20const%20interval%20=%20setInterval(()%20=>%20{%20window.scrollTo({%20top:%20document.body.scrollHeight,%20behavior:%20'smooth'%20});%20count++;%20if%20(count%20>=%2010)%20clearInterval(interval);%20},%201000);%20})();
  

  Skip YouTube video ad:

      javascript:(function()%7Bvar%20skipButton=document.querySelector('button.ytp-ad-skip-button-modern');if(skipButton)%7BskipButton.click();%7Delse%7Bdocument.querySelector('video').currentTime=document.querySelector('video').duration;%7D%7D)();

  Bookmarklets are effectively dead, unless they're extremely simple or you use Firefox. It's kinda ridiculous that they've been effectively blocked by changes to browsers (like chromium-based ones) that make it nearly impossible to run JavaScript from the address bar, along with "Content Security Policy" rules that enable widespread blocking of inline scripts.

  It's unfortunate that browser developers want to fully derisk all potential security holes, because that also means removing the choice from the end user. This ends up being security by infantilization.

    You could probably still run a JavaScript program from the developer console, though. (However, I think that does not allow it to run from bookmarks, unless it already can.)

    > It's unfortunate that browser developers want to fully derisk all potential security holes, because that also means removing the choice from the end user.

    I agree with you, it is unfortunate. (There are other cases of this too, though.) (I think there are other ways to fix security issues though, while allowing more and better control by the end user; but, they don't tend to do such things.)

    I can't confirm this. Here, bookmarklets are working just fine on all browsers, including chromium-based ones.
