html – How can I scale the content of an iframe? – Stack Overflow

Posted by jpluimers on 2021/08/19

I used [WayBack] html – How can I scale the content of an iframe? – Stack Overflow as starting point to scale some iframes.

In my case, I had to scale up (by a 25% so a factor 1.25) instead of scale down.

What I observed so far in recent Chrome versions is:

  1. The wrapping div is still needed, otherwise the outer size and inner size of the frame mismatches
  2. The wrapping div and the wrapped iframe need to have the same dimensions (so unlike the Stack Overflow answers, no need to scale the width/height of the div; keep the same values as the iframe)

The div uses class calendar_wrap.

The iframe uses class calendar_iframe.

This is part of my CSS:

body {
      margin: 0; /* override browser setting for body `margin: 8px;` */
      overflow: hidden; /* remove scroll bars; does not work for iframes  */
    }

    /* ... */

    iframe {
      border-width: 0; /* override browser setting for iframe `border-width: 2px; */
      height: 100vh;
      width:   50vw;
      overflow: hidden; /* remove scroll bars; does not work for iframes  */
    }

     /* wrap and iframe zoom as per https://stackoverflow.com/questions/166160/how-can-i-scale-the-content-of-an-iframe */
    .calendar_wrap {
      float: left;

      height: 70vh;
      width:  35vw; /* calc(35vw / 1.25); */

      padding: 0;
      background-color: blue;
    }

    .calendar_iframe {
      float: left;

      width:  35vw;

      -ms-transform: scale(1.25);
      -moz-transform: scale(1.25);
      -o-transform: scale(1.25);
      -webkit-transform: scale(1.25);
      transform: scale(1.25);

      -ms-transform-origin: 0 0;
      -moz-transform-origin: 0 0;
      -o-transform-origin: 0 0;
      -webkit-transform-origin: 0 0;
      transform-origin: 0 0;
    }

    /* ... */

Firefox: disable DNS over HTTPS (which they call TTR)

Posted by jpluimers on 2021/08/03

There are many reasons to disable DNS over HTTPS (DoH), of which enough are discussed in the links below.

Disabling DoH always talks about setting TTR (the abbreviation Mozilla uses for it) to 5 (like [WayBack] Thread by @isotopp: “Firefox is about to break DNS by enabling DNS-over-HTTP by default […]”), but hardly ever explains the meaning of 5, or any other potential values.

After some searching, I found [WayBack] Firefox disable trr | Knowledge Base:

  • 0: Off by default
  • 1: Firefox chooses faster
  • 2: TRR default w/DNS fallback
  • 3: TRR only mode
  • 5: Disabled

I imagine the setting we’re all looking for is: user_pref(“network.trr.mode”, 5); (emphasis mine)

It pointed me to [WayBack] Trusted Recursive Resolver – MozillaWiki:

How do i get the old CTRL + TAB function back

Posted by jpluimers on 2021/07/19

I hate those updates (this time around FireFox 65) where suddenly the UX changes without an obvious way to switch back to the old behaviour. [WayBack] How do i get the old CTRL + TAB function back? | Firefox Support Forum | Mozilla Support led me to the proper name (“browser.ctrlTab.recentlyUsedOrder”), and a confirmation of the below steps in:

I by now know this is only for new user profiles, but since I do not sync profiles (as almost all of my equipment servers different use cases), but still have the same physical user (me), I want consistent behaviour. See [WayBack/Archive.is] Enable “Ctrl+Tab cycles through tabs in recently used order” feature by default in new profiles

Script needed

Too bad I could not find a way to script this: my [WayBack] Mozilla Bugzilla “browser.ctrlTab.recentlyUsedOrder” “script” – Google Search turned no useful results.

If you have a scripting workaround, please let me know.

Resetting to the old tab behaviour

For me, the easiest way is to

  1. browse to about:config,
  2. confirm “I accept the risk!”,
  3. type “tab” in the “Search” pane,
  4. select browser.ctrlTab.recentlyUsedOrder,
  5. double click on the “browser.ctrlTab.recentlyUsedOrder” entry to switch from non-bold true (default value; wrong) to false (actual value; correct).

No need for any save button: the change is immediate.

These might help me script it:

Thread:

Jammer dat het Privacy Statement op mijnlumc.lumc.nl/mijnlumc/?#/co… als een pop-up zichtbaar is, waardoor je het niet volledig kunt afdrukken of als PDF opslaan.

Vreemd ook dat de tekst op lumc.nl/12367/ anders is dan in de consent hierboven.

Kan @LUMC_Leiden dat oplossen?

Idem voor de Gebruiksvoorwaarden. Daar is geen alternatieve tekst van.

ColumnCopy – Chrome Web Store

Posted by jpluimers on 2021/02/19

[Archive.is] ColumnCopy – Chrome Web Store: Enables copying columns from tables.

It can read anything on any web page, and it uses modifier keys, so I usually have it disabled until I need it.

You can disable/enable it on this page:

chrome://extensions/?id=lapbbfoohlcmlbdaakldmmallcbcbpjb

Via [WayBack] Select column from a table with Google Chrome – Super User

Sorry to dig up an old thread, but this might help someone in the future. I wrote a Chrome extension called ColumnCopy which accomplishes this task.

Deleting the WebCache database – The IE browser cache | Apttech’s Blog

Posted by jpluimers on 2021/02/15

[WayBack] Deleting the WebCache database – The IE browser cache | Apttech’s Blog quotes from WayBack: C drive space is using up on terminal server after upgrading to IE10 or IE11 – AsiaTech: Microsoft Azure & Development:

With the new cache implementation, the cache files are saved in %LocalAppData%\Microsoft\Windows\WebCache\ folder. And, the cache files will be created when a new user logs on.

Actually, the database is a file named WebCacheV01.dat in the cache folder, and its initial size could be around 20-32MB. The size of this file will keep increasing along with you browse more and more websites.

…

save the below contents into ClearIECache.cmd file and try to fun this file.

echo OFF
net stop COMSysApp
taskkill /F /IM dllhost.exe
taskkill /F /IM taskhost.exe
taskkill /F /IM taskhostex.exe
del /Q %LocalAppData%\Microsoft\Windows\WebCache\*.*
net start COMSysApp
echo ON

Furthermore, you’d better deploy the batch file to a logoff script of your local GPO, here are the steps.
