Things That Don’t Get Firefox To Start Loading Pages Again When It Decides It Doesn’t Want To

Firefox as of v 148 (actually a bit earlier than that, but that's what I'm on right now) frequently decides not to load pages anymore. You enter a URL or click on a link and get the status message "Waiting for [URL]..." and you can wait as long as you care to.

When this begins, your only choice is to restart Firefox.

Here is a list of "solutions" to the problem from around the web, which I have tried and found do not fix the problem:
• Turning off DNS-over-HTTPS in Firefox Settings
• Flushing MacOS's DNS cache.
• Going to about:networking and clearing Firefox's DNS cache
• Going into about:config and changing network.dns.disableIPv6 from false to true
• Opening in "troubleshooting mode" or disabling all extensions
• Turning VPN off
• Turning VPN on

iOS Shortcut to dictate your shopping list into Reminders.app

I uses this shortcut to dictate my shopping list into the iOS Reminders "Shopping" list. It breaks spoken lists on the word "and" to create separate shopping list items.

So I might run the shortcut, say the phrase "pickles and hot dogs and mustard", and it will add "pickles", "hot dogs", and "mustard" as separate checkbox items to the Shopping list in Reminders. It's handy for rattling off my shopping list as I'm staring into my fridge.

Obviously you need a list called "Shopping" set up in your Reminders app.

This shortcut executes the following steps:

  1. Dictate text - listens for spoken input. Make sure set to '''stop listening after pause'''.
  2. Split Dictated Text by Custom and - splits the text into a list with "and" as the delimiter
  3. Repeat with each item in Split Text - begins the loop that adds…

SSH into local mac, error “WARNING- REMOTE HOST IDENTIFICATION HAS CHANGED!”

SSHing into a local MacOS machine at address "macbook.local", I suddenly got this:

[code]@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that a host key has just been changed. The fingerprint for the ED25519 key sent by the remote host is SHA256:oKCEu3pDdq7xBhSPZwOzR2q0eWTvfphtvn3D4Bjz8v4. Please contact your system administrator. Add correct host key in /Users/username/.ssh/known_hosts to get rid of this message. Offending ECDSA key in /Users/username/.ssh/known_hosts:147 Host key for macbook.local has changed and you have requested strict checking. Host key verification failed.[/code]

The solution was to run ssh-keygen -R macbook.local then try the ssh again. Then it asked me whether or not to accept the key, instead of rejecting it:

[code]$ ssh username@macbook.local The authenticity of host 'macbook.local (fe80::1890:fd32:c304:69cd%en0)' can't be established. ED25519 key fingerprint is SHA256:oKCEu3pDdq7xBhSPZwOzR2q0eWTvfphtvn3D4Bjz8v4.…

Xbar/BitBar gives “Couldn’t Posix Spawn” for script.

Apple's quarantine system can cause this. Try 

[code]chmod +x com.apple.quarantine /path/to/script.sh xattr -d com.apple.quarantine /path/to/script.sh[/code]

In my experience only the xattr is needed but the chmod might help and couldn't hurt.

Prevent MacOS from locking screen when you disconnect screen sharing

I screenshare into a Mac for playing video on my TV, and had an intermittent problem where Firefox would not play video while screen sharing was connected, but then locked the screen as soon as I disconnected.

It turns out that if the screen is locked when you log in via screensharing, MacOS defaults to locking it again when you disconnected, and, being MacOS, the ability to turn this off has been removed from the UI.

Enter this in terminal to turn it off: sudo defaults write /Library/Preferences/com.apple.RemoteManagement RestoreMachineState -bool NO

Getting Web Browsers Not To Blur Images on Retina Screens

Unfortunately this must be set by site, but on retina screens on MacOS, many browsers blur small images, such as 88x31 buttons.

You can overcome this, at least for the images on your site, by adding this CSS to your site:

img, div {
image-rendering: optimizeSpeed;
image-rendering: -moz-crisp-edges;
image-rendering: -webkit-optimize-contrast;
image-rendering: optimize-contrast;
image-rendering: pixelated;
-ms-interpolation-mode: nearest-neighbor;
}

You should add any element that might have a CSS background image property to that selector. In this case I have added

because I have many divs with background images on this site.

This tip is from https://stackoverflow.com/questions/31908444/fix-for-blurry-images-on-browsers-used-by-a-mac-retina

How to fix if the “Save” button is grayed out in Photoshop CC 2017 save and export dialogs

I don't know if this affects other versions of Photoshop, but on MacOS Photoshop CC 2017 frequently starts unexpectedly graying out all save buttons when you have made changes to your file and should be able to save.

The secret is to resize and move around the dialog. Drag the lower right corner to make it bigger and smaller a few times, and try dragging the whole dialog to the upper left corner of the screen and making it small.

This fixes it for me.
