FFF doesn't open Links in Chrome for Browser Cache

[M3We]

I've had this feature working for a while, and then did a bunch of updates over Christmas, and suddenly items no longer open in Chrome to populate the cache. I've gone through troubleshooting and isolated it to the "open_pages_in_browser:true" is not working.

System Info:

• Mac OS
• Calibre 7.23
• FFF v4.41.0
• Chrome build: Version 131.0.6778.205

Personal.ini

[defaults]
## Some sites also require the user to confirm they are adult for
## adult content.  Uncomment by removing '#' in front of is_adult.
is_adult:true

browser_cache_age_limit:3.0
open_pages_in_browser:true

[epub]
## include images from img tags in the body and summary of stories.
## Images will be converted to jpg for size if possible.  Images work

If you run Calibre in Debug mode (under Calibre's Preferences drop down), the log should show whether FFF is trying to open pages or not.

We had a very similar problem a couple months ago and the solution was for FFF to call Calibre's 'open in browser' method instead of the Python library version.

At the time, a user said they could configure a different browser for Calibre specifically.

I've never used that setting, but it appears to be openers_by_scheme in Calibre > Preferences > Tweaks. That may help.

Opened with Debug - Got the following:

	open page in browser: https://www.fanfiction.net/s/12510179/1/Meddling-with-Potions
	tries:None
	
	This plugin does not support QPlatformServices::openUrl() for 'https://www.fanfiction.net/s/12510179/1/Meddling-with-Potions'.
	QDesktopServices::openUrl() failed for url: PyQt6.QtCore.QUrl('https://www.fanfiction.net/s/12510179/1/Meddling-with-Potions')

(Let me know if there's anyything else in the logs I should look at)

RE openers_by_scheme - Currently reading the doco on making it work

I do not believe the plugin in This plugin does not support ... is the Calibre plugin, I believe it's a Qt thing. Google search finds the same error else where.

So maybe Calibre's openers_by_scheme will help, but it looks like it's outside anything I can help with.
