== Steps to reproduce ==
1. Open https://forums.tomshardware.com/threads/what-is-the-actually-difference-between-udimm-and-dimm.1575984/
2. Right-click and select ’Save page as’. Point the dialog to your directory of choice.

== What I expect to happen ==
For the directory to contain a downloaded copy of the page.

== What happens ==
There’s no copy of the page in the target directory. Going to about:downloads reveals that the download has failed, without further details.

== Other info ==
I’m reporting this from up-to-date Disco, albeit with a 4.* kernel (as gdm currently fails to start in my VirtualBox VM with 5.*) but it’s equally reproducible in Bionic.

Any page under https://forums.tomshardware.com/ seems to trigger this, but I have yet to come across other sites that do. Pages can even be saved from the main Tom’s Hardware domain (https://www.tomshardware.com/) without issues.

Onomatopoetian ohella merkitykseltäänkin: Rapala.

It works! Brilliant, thanks a lot!

I’m having a problem adding a custom image when the generated preview has already picked up an image. If I remove the automatically linked image, the ’Remove Image’ button remains as such, so there’s no ’Add Image’ button in its place to add the custom image.

As an example, here’s a recorded gif of my attempt to customize the image when linking to this page on Tukes’ website.

With few hints about preview-suitable content provided by that page, Visual Link Preview picks up an overlay image (magnifying glass), which I’d then like to replace with the actual image (a safety reflector) from that page (after already downloading it). But after I click ’Remove Image’ to remove the overlay image, I have no way to add the correct image, because the ’Add Image’ button is missing.

I’m using the current latest release of the plugin (2.0.1) in WP 5.1.

I’m using yle-dl from the HEAD and ffmpeg & ffprobe built from git. For the three URLs listed above, I could only get subtitles to download for the last one (with --debug) until I tried playing it in the web player, after which they were no longer downloaded for that one either. Aargh :)

Here’s --debug output for the first download (before opening in webplayer), resulting in subtitles being downloaded.

Here’s --debug output for the latter download (after opening in webplayer), resulting in subtitles not being downloaded.

Eipä tuosta enää taida puuttua kuin että käväiset A2-illassa kilpahuutamassa. :o)

Höh, noin paljon medianäkyvyyttä, ja minä silti vasta tämän kautta ensimmäistä kertaa törmäsin mihinkään noista. Hyvin olen suotimeni näköjään säätänyt (kaikki perhe- ja ihmissuhdejutut = block).

Mukava nähdä, että vaikutat tyytyväiseltä. Haters gonna hate.

Another option missing from the man page is -ow (for overwriting the input file in-place), available since version 1.7.22.

$ pngcrush 2>&1 | grep -- -ow
    pngcrush -ow [other options] file.png [tempfile.png]
        -ow (Overwrite)

Tested this again and it seems to have been fixed at some point by some Ubuntu (18.04) updates: my test user still had version 8 of the extension, and I could no longer reproduce the issue, neither before nor after updating the extension to release v9. My main user’s desktop now also appears unaffected.

(I was going to try the workaround reported by @ChrisLancs, but ended up not having to. My ”List type” is set to ”Disabled”.)
