User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:136.0) Gecko/20100101 Firefox/136.0

Steps to reproduce:

Installed 134.0, 135.01, 136. I originally had 107 installed. I then visited the following sites:

1. https://modis.gsfc.nasa.gov/
2. https://www.spaceweather.com
3. https://www.bbc.com/

Actual results:

1. is missing its main title and eg. the search button on the same line. (I can't even find the title with 'Inspect') It is not selectable
2. is missing all its main text. The text is selectable and appears if selected. (screenshot attached).
3. not quite sure, I think there was a big title, along with some buttons, on the home page, now it's all black.

Expected results:

1. Normal title should appear. I tried to disable the 'Dark Theme' no difference.
2. Text should appear normally
3. Title should appear

NOTE: all these problems did not appear in version 107...

The Bugbug bot thinks this bug should belong to the 'Toolkit::Find Toolbar' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

I seriously doubt that this reclassification is correct.

It could have something to do with rendering content, CSS, etc, but I doubt it's a Find Toolbar error

Suspect this is more to do with layout / styling rather than gfx, due to elements not being selectable and WR having no concept of light / dark mode?
