i’ve been using firefox and its predecessors since the very beginning, all the way back to pre-release navigator.

i do have (and have always had) other browsers installed (using ‘portable’ installations of them, mostly, these days). currently those include vivaldi, opera, librewolf and waterfox. at least one of which is added along side firefox on each desktop (most often also with a firefox dev edition). these are mostly for testing but also to separate specific online tasks into their own browser. the chromium-based ones are used for very specific things requiring addons that don’t work well or at all with firefox.

unless i need to in order to assist a client, i do not use chrome as provided by google, and i do not use edge from microsoft except for its primary function: downloading another browser when i don’t have a flash drive handy with its installer already downloaded and saved to it.

having actually read the policy documents in question and considering the intent and purpose of the changes that mozilla is making, i have no plans on changing my primary browser.
