&gt; In what way? The only difference I can see is the download status bar, but that&#x27;s available on firefox as an extension.<p>Yes, I&#x27;ve tried to replicate Chrome&#x27;s UI with Firefox extension. But it <i>feels</i> like I&#x27;m using extensions. Furthermore, I really don&#x27;t enjoy configuring browsers because between work, school, and hobbies I use a lot of different machine. For this reason, if I&#x27;m using firefox, it&#x27;s usually with the default UI... which is not my personal preference.<p>&gt;&gt; has the best extension ecosystem.<p>&gt; Can you elaborate this?<p>Take a cursory glance at each of the two stores:<p><a href="https:&#x2F;&#x2F;addons.mozilla.org&#x2F;en-US&#x2F;firefox&#x2F;" rel="nofollow">https:&#x2F;&#x2F;addons.mozilla.org&#x2F;en-US&#x2F;firefox&#x2F;</a><p>vs<p><a href="https:&#x2F;&#x2F;chrome.google.com&#x2F;webstore&#x2F;category&#x2F;extensions" rel="nofollow">https:&#x2F;&#x2F;chrome.google.com&#x2F;webstore&#x2F;category&#x2F;extensions</a><p>Aesthetically speaking, the firefox add ons page is the Tux Racer to chrome&#x27;s Mario Kart.<p>One has the passion and enthusiasm of well respected open source volunteers behind it, and the other has a sleek high quality shine only our dear corporate overlords could deliver. 
This is minor, but it sets the mood the for the whole experience of add ons. 
(Of which, I only <i>need</i> uBlock Origin&quot;). In general, it&#x27;s easier to find what I&#x27;m looking for, see what&#x27;s trending, and generally browse for extensions in the chrome store. 
EDIT: The chrome store is also much faster and more responsive.<p>Aside from that, Chrome seems to have more active developers because of it&#x27;s better brand name. On &#x2F;r&#x2F;cscareerqustions, for example, you&#x27;ll hear people ask about ideas for resume-boosting side projects. One of the first answers is usually &quot;make a chrome extension&quot;. I have yet to see anyone say &quot;make a firefox extension&quot; or &quot;make a cross platform browser extension&quot;.<p>Either way, it&#x27;s all personal preference. I&#x27;m sure you prefer a different model car, style of clothing, and a favorite color than me too. It&#x27;s all ok. There&#x27;s no right answer here.
