Yes, it will copy everything related to that profile. The passwords are stored in the key4.db file so it shouldn't be copied in that situation.

Then there's also the sync feature which might import the passwords even if the file has been deleted, so the sync needs to be disabled on the work pc.

The pressure to review thousands of horrific videos each day – beheadings, child abuse, torture – takes a devastating toll on our mental health

What could be a solution for dealing with that? I wouldn't want to be exposed to that type of content even if I was paid to do so and had access to health support to deal with the aftermath every time.

a kindergarten-level understanding of German.

I love the serendipitous use of kindergarten, with it being of German origin :)

A lot of this was already covered but here's what I have:

• Lights/screens:
  • Switching to light sources/bulbs with lower brightness/warmer light temperature (lower Kelvin/K-value) 3 hours before bed. (Light affects our sleep-wake cycle, aka the circadian rhythm. Our brain processes bright light as "the sun is still up so it's not time to sleep yet")
  • Gradually dimming electronic screens until bedtime. (Computer: using a program like F.lux and lowering the brightness gradually in the graphics card's control panel. Phone: with a built-in Night/Dark Mode option that you can schedule or by using an app like Twilight). // Don't take your devices to the bedroom, or keep them far away from the bed and set them on silent/shut them off.
  • Use a face mask (or tie some other cloth around your eyes), or sleep in a dark room (closed door, covered windows, covered LED lights on electronics, etc.) (note: if you sleep in a closed room make sure to keep it well-ventilated in all other hours)
• Try not to sleep for more than 8 hours, so you'll always be tired enough the next night.
• Masking noise:
  • Use something that makes a white noise - a loud fan/air purifier, a plugged-in radio that's not tuned to a working station, a white noise device, etc. (put it next to a window if it's noisy outside to mask the noise better)
  • Additionally (or alternatively) you can use foam earplugs. Just make sure to roll&squeeze them before putting them in and don't push them too far, otherwise you might get impacted earwax and have difficulty getting them out.
• Food: Have a light meal 3-3.5 hours before bed and light snacks (like crackers) 1.5-2 hours before bed, to not go to sleep hungry and get distracted by that and to not put the body into overdrive by having to digest a heavy meal, or cause heartburn/indigestion.
• If you sleep on your stomach with your head to the side, you can use a thin and narrow side pillow (but firm) along your torso to support your shoulder on the side that your head is pointing to. (you can also use a thin pillow for your head to not strain your neck/spine - there are ones made for kids if needed)

This type of flaw occurs when memory that has been freed is still used by the program

Am I understanding correctly that a memory leak has been fixed? Though it says that it relates specifically to "Animation timelines", so does it mean that the fix only affects the (small?) portion of the memory that's been used by that feature? Or any memory that should get freed but wasn't previously?

For the more advanced, you can also mess around with the userChrome.css file. To create it open a text editor and save the file as userChrome.css in the \Chrome folder in your Firefox profile folder* (make sure to restart Firefox to apply the changes)

To enable the file, enter about:config in the address bar, then accept the warning if it appears. Search for toolkit.legacyUserProfileCustomizations.stylesheets and double-click it to set it to true.

*enter about:support in the address bar, or click on the Help menu > More Troubleshooting Information, then scroll to the Profile Folder line and click on Open Folder. Usually it's C:\Users\~USERNAME~\AppData\Roaming\Mozilla\Firefox\Profiles\~PROFILENAME~

*Note: the first 2 lines about tab height might not work if you don't have the Playing/Muted text line in tabs disabled. To disable that line go to about:config, search for browser.tabs.secondaryTextUnsupportedLocales, and add ,en (or the relevant language that you're using in your system) at the end of the value for it then click Enter and restart Firefox to apply the change.

Here's the userChrome I use (compiled from different sources)

It can be 👍

I also didn't have a need for it and wanted to disable it and I found browser.tabs.hoverPreview.enabled in about:config (set it to false to disable).

There's also browser.tabs.hoverPreview.showThumbnails to only disable the image preview but not the new layout of the tooltip (there's also a corresponding option for it in the main settings)

Especially for sleeping issues, but also for eye strain, I recommend using a program like flux (for a computer) that allows you to set the color temperature for the day and the gradually lower it further at evening and night. This along with dimming or using different lower temperature lightbulbs in the evening/night (not being exposed to bright/florescent lights) really helped me with falling asleep.

edit: also, lowering the brightness on the monitor itself (mine is set to 27) and in the graphics card control panel (39 for me), and then manually lowering it further in the evening/night in the control panel (25>15>9>0 is how I do it)
