If you're a userChrome.css user and your tab height increased on 96.0.2...
If you use userChrome.css to customise the tab toolbar, you might see the height of the tabs increase with Firefox 96.0.2. For me the fix was to add an entry to userChrome.css:
#tabbrowser-tabs:not([secondarytext-unsupported]) .tab-label-container { height: initial !important; }
This counteracts a change in 96.0.2 which sets the height of that element to 2em.

You can hide the secondary line that shows the Playing and Muted state by modifying the browser.tabs.secondaryTextUnsupportedLocales pref and add your language to the list. For "en-US" this would be "en" (i.e. the part before the '-'):
- ar,bn,bo,ckb,fa,gu,he,hi,ja,km,kn,ko,lo,mr,my,ne,pa,si,ta,te,th,ur,zh,en
You need to close and restart Firefox after modifying this pref.
