Visit about:compat in your firefox. I find it insane that these exist.
Edit: I’ve learned that this is part of the webcompat system addon developed by Mozilla and other contributors. I see why this is beneficial default behavior, since FF has no chance of getting enough market share to matter more if things are broken.
However, this behavior is too intrusive for my taste. For example this injection: https://hg.mozilla.org/mozilla-central/file/8a4afb4d34f8/browser/extensions/webcompat/injections/js/bug1472075-bankofamerica.com-ua-change.js is basically just to silence annoying user reports.
Also, Every site FF pretends to be a different UA on is artificially reducing FF market share data.
This isn’t even an issue though, its just to fix bugs with certain websites that block Firefox for no reason or have other weird compatibility issues. Which I would think is a good thing?
You’re right, for a browser meant for the masses it is probably a net benefit. I posted because I was surprised by this hidden behavior that seems better suited for a browser extension. Sneaky behavior like this is what I’m paranoid about in closed software like windows.
To your point, Linux itself is probably the #1 example of hacky patches to work around other people’s problems.
I don’t think that Sneaky or Secret are good descriptions for this. A better word might be “plumbing”.
When you realize that your house use full of hidden pipes and wires, it would be a strange take indeed to conclude that anybody is being “sneaky” about these “secret” features.
