Twitter, Firefox, non-breaking spaces: how to achieve what you want?

Question

More recently, Twitter, when opened with a browser, has a new (more visual) microblogging editor, in which @-sequences are highlighted in blue, in which extra characters (beyond 140 characters) are highlighted with an alarming pink background, and so on.

But I've noticed, to my annoyance, that the Twitter tweets I type from Firefox are replacing non-breaking spaces with normal spaces.

Meanwhile, non-breaking spaces are necessary in many cases:

• between initials and surname, as well as between the initials themselves,
   
• after abbreviations of addresses ("Comrade Semyonov") or geographical names ("Samara City"),
   
• inside abbreviations ("etc.", "etc.", "i.e."),
   
• before units of measurement ("16 kg", "35 years"),
   
• before dash,
   
• in front of software version numbers or designations (“Windows 7”, “Windows XP”),
   
• between groups of numbers ("33,130 bytes"),
   
• after prepositions and conjunctions (single-letter, two-letter, especially at the beginning of sentences), after the particle “not”, before the particles “would”, “whether”, “same”.

From the Twitter app for Android, non-breaking spaces are sent correctly, so hopefully this isn't some kind of "crusade" by the Twitter administration to eliminate non-breaking spaces.

Therefore, a number of questions arise for the Habrakhabr community: tell me, readers, do you observe similar behavior of Firefox, how are things with other browsers, who is to blame for what is happening (Firefox or Twitter), who and how should be pushed to solve this problem?
