So, trying to unpack the OP's multiple questions a little:<p>1. Preventing Firefox going out of business
-> as noted by others, Mozilla is actually doing decently well financially, and continues to dedicate a large part of its resources to Firefox
-> however given some of its revenue sources, maintaining a certain share of users is important to maintain that state of affairs<p>2. Driving more adoption of Firefox
-> Most users have pretty simple browsing needs, and a non-negligible share still don't know what a browser is (we all know a few I wager) while still using one daily,
-> Competing browsers have semi-exclusive or exclusive distribution channels for their products which help drive their adoption (Google.com, some Android flavours, ChromeOS / Mac and iOS / Windows, Bing, Outlook & Office)
-> Thus as with any product, driving adoption could be done by:
--A. offering a killer feature many (actual) people care enough about to download the browser for - for most people, this would need to be significant speed or friction reduction (Adblock, etc) which Firefox already does well but perhaps not significantly well enough
--B. get users early, i.e. partner with websites, apps and influencers that reach younger users to promote/recommend Firefox and its features, notably on the privacy and personalisation side (themes, meta filter, Adblock, password and history sync, etc) - think some viral Tiktoks on the benefits or simple product placement
--C. get a series of not-just-tech ambassadors to promote the browser along with the work of the Foundation, which may be done cheaply as they do have commendable initiatives
--D. Partner with like-minded organisations to recommend each other's solutions where possible, e.g. Automattic or such
-- etc etc<p>Firefox has been my daily driver on all devices for 20+ years. I personally feel it's never been as good as it is now: it's fast, the memory woes are gone, the sync works like a charm, password suggestion and management is seamless, the Android version is great (love the bottom navbar option).<p>Probably not perfect - what is - but I just wanted to share a more upbeat comment here, and perhaps one more geared towards the majority of users, who will be less technical and choose their browser's (or better said default to their browser's) for vary different reasons.
