Bug Summary

When the setting: "Open previous windows and tabs" is disabled, and a custom image is selected on the Floorp Home Background, the image does not display, instead, it uses a non-valid url as its background.

This only happens in the first about:home opened in the browser. If another instance of the profile is open, the bug does not occur.

Reproduction Steps

1. Create a new profile
2. Select a custom image for the new tab by using the about:preferences#home
3. Disable "Open previous windows and tabs"
4. Close the window or all the tabs
5. Start the profile again

Expected Behavior

Custom Image appearing as the background of the home page

Actual Behavior

Solid black color where the custom image should be

Actual Behaviour:

Console:

Browser Version

11.14.1

Operating System

Windows 11

Additional Context

It only affects the first home page of a profile and always happens.

The URLs seem to be the same (although randomized):

Working url: blob:null/a530871f-260b-47ef-9ca0-1eb1cb46f608

Not Working url: blob:null/7eb414b1-cd9a-45d0-a5a5-c06a2627d8f1

Also, I get this from the console:

The issue most likely has to do with this: LoginHelper(Main): Couldn't parse specified uri blob:null/7eb414b1-cd9a-45d0-a5a5-c06a2627d8f1 with error NS_ERROR_FAILURE LoginHelper.sys.mjs:693:18

Also, this is nothing new of any recent update. This has been happening to me for the last few months.

This was already reported here #619

A fix couldn't be found this issue, but changing the value of browser.startup.homepage.abouthome_cache.enabled to false in about:config does seem to be a temporary solution.

[Perseus333]

I see. I'm sorry for the duplicate bug. It's a shame that no actual fix could be found.

It's a shame that no actual fix could be found.

Definitely try changing the value of that pref I sent earlier. It does work well.
