That's a great workaround, could you share the command?

Beta? It isn't experimental, it was an official feature that is no longer supported (even if it still works perfectly).

As I said somewhere else, to get more compact tabs you can go to about:config and search for a setting called browser.tabs.tabMinWidth, I usually change the number to 20 (the default minimum width is like 70) and tabs are allowed to become roughly as narrow as in chrome. And if by "more compact tab bar" you meant how tall tabs are, there's the browser.compactmode.show setting, put it to "true" and then in the Firefox menu under More Tools → Customize Toolbars you can select "compact mode" in the "Density" menu on the bottom, which makes the tab bar and toolbars shorter

According to this study a mealworm farm uses more energy per kg of protein produced compared to chicken, but much less energy than any other meat. However, mealworm farms rank lowest in CO₂-equivalent emissions per kg of protein and lowest in land use compared to all meat products, including chicken.

Apparently soy beans produce 6.82 kg of CO₂-equivalent per kg of protein isolate (which is 90% protein, therefore 7,5 kg of CO₂-equivalent per kg of protein), while mealworm farms produce 14 kg of CO₂-equivalent per kg of protein (and around 30 kg for chicken, the next best option). Worse, but less than double.

As for land use, the first study calculates that to produce 1kg of protein from mealworms it is necessary to use 18 square meters of land per year (including the land to grow food for the worms) while according to this other study vegetable proteins need up to 25 square meters of land per year for each kg of protein.

I admit it's not as big a difference in land use as I thought (it's different studies, they might have slightly different metrics) , but I think there are other factors that make it a much more complicated issue: mass use of fertilizers, monocultures, deforestation, soil impoverishment... An advantage of mealworms might be that you can give them a variety of foods that are easier on the soil (the first study mentioned carrots, grains and other stuff) in order for them to produce protein, while protein-heavy plants require rich soil and tend to drain it fast.

The whole eating insects idea is motivated by carbon emissions and similar concerns: insect meal is around 60-70% protein (beans are around 30%, maybe bean meal is more but I have never seen it anywhere), and its cost in terms of emissions and land use is much smaller than either meat or plants (especially stuff like soy). Nobody is arguing that it should replace beans. Rather, it could help diminish meat consumption.

Ok I admit I never thought about using ublock on thunderbird but it sounds interesting, could you explain what advantages it and those filters give? As far as I know TB already blocks some elements within emails for security and privacy purposes
