Firefox 136 Custom Homepage Custom Shortcut Image URL Super SLOW!

[mliving]

Most of my Firefox Home Content links use a single Custom Image URL for the icon and they take an awful long time to load since ungradeing to 136. Previous versions had a slow load the very first time after install and then were instant until I changed or updated the icon.

Is there no way Firefox can't cache these icons?

Either way there is a huge difference in load times with 136.

Just wanted to add that it isn't the server I'm storing the icons on. Ping tests show the response time is the same as www.apple.com.

Hi, this is an old "battle". I've already gone through this with them. You can find the thread on bugzilla:

Https://bugzilla.mozilla.org/show_bug.cgi?id=1870342

The TLDR is: you open firefox, wait for all images to load, go to your profile folder, open the folder "Thumbnails", select all files (these are the cached images) right click -> properties -> mark as read only.

Next time you start the browser the images are already cached.

I know, kinda dumb the need to do this but it was the way i solved it.

Anytime i add another custom image, i need to make that as read only too.
