## レビュー

### "Firefox is my favorite browser. Easy to use and reliable" — 5.0/5

> **Michelle** | *2025年5月8日* | 小売 | おすすめ評価：10.0/10
> 
> **良いポイント**: I love Firefox. I have used it for many years and love the tools and features it has. It is my secondary browser. It is very user friendly and customizable.
> 
> **改善点**: Not really anything. I only started using Chrome primarily because of the Google Tools I regularly use.
> 
> Overall I have never had a bad experience with Firefox. I have always had minimal technical issues with it and it has always performed fast for me. It has never been hard to use or find out how to use the features of the browser

### "Firefox: Why Are You Reading This Review? Stop Using Google Chrome LOL" — 5.0/5

> **Caleb** | *2025年4月14日* | 執筆、編集 | おすすめ評価：10.0/10
> 
> **良いポイント**: I prefer Firefox to other browsers because its a happy middle-ground of functionality and privacy. Google Chrome is fast and sleek, but it chugs through RAM and tracks everything you do. Brave doesn't track every single click and cookie, but it's a little on the slow side, and some of the sites I visit don't work on it at all. Firefox is the best of both worlds: it's fast, functional, and doesn't steal my personal information (after changing some settings). I like that Firefox offers multiple search engines by default, including DuckDuckGo. I appreciate that there are so many add-ons available, and that they are (mostly) vetted by Mozilla. I've been using Firefox for years. I expect that won't change any time soon.
> 
> **改善点**: This isn't an issue with Firefox per se, but the website I use to view my paychecks doesn't work on Firefox. I wish using Firefox was more commonplace in office settings.
> 
> Overall, I'm quite pleased with Firefox. I like that it doesn't bog down my computer or chew threw my data. I appreciate that it allows for some customization via themes and add-ons, and that there isn't any shady data collection going on. I much prefer Firefox to other web browsers.

### "Your fired fox" — 3.0/5

> **Joshua** | *2025年11月15日* | 建設 | おすすめ評価：0.0/10
> 
> **良いポイント**: Its content approval. Firefox will just about let you have access to most any format of data you desire.
> 
> **改善点**: Its Features and functionality of the browser itself, lack any quality or exuberance. Its just to outdated.&#10;Feels like im swimming in syrup,&#10;When trying to load pages.
> 
> I wouldnt say I had  a bad experience.&#10;I wouldnt say I had a good one either.&#10;Its just not my cup of tea.

### "Firefox works\!" — 5.0/5

> **Birte** | *2026年1月16日* | 個人および家族向けサービス | おすすめ評価：10.0/10
> 
> **良いポイント**: Privacy - and the option to customize my preferences.&#10;I have used Firefox for about 10 years, maybe more - and find it hard to even imagine using another browser.
> 
> **改善点**: I cannot think of anything that I dislike. Firefox is actually really easy to manage - in every way.
> 
> My experience with Firefox is great\! I love the automatic update, being able to customize settings and it doesn’t make my laptop slow.

### "Firefox works great for me\!" — 5.0/5

> **Robin** | *2025年1月28日* | 保険 | おすすめ評価：10.0/10
> 
> **良いポイント**: It’s compatible with everything and it’s easy to have multiple profiles.
> 
> **改善点**: I don’t dislike anything. Everything with it works well.
> 
> I’ve been using Firefox for a long time now. For a lot of companies I’ve worked at, their proprietary websites only work with Firefox so it’s necessary to use. It works really well and I don’t encounter a lot of errors.
