[Google Chrome](https://www.capterra.jp/software/1012057/chrome) — 4.8/5 (2134 reviews) ## レビュー ### "The Gamers Best Friend" — 5.0/5 > **Percival** | *2025年7月5日* | エンタテインメント | おすすめ評価：7.0/10 > > **良いポイント**: I love how much lighter it is on my PC while I am doing other things at the same time\! It doesn't get bogged down nearly as much as it did when I had my previous browser; I noticably get better CPU/GPU performance when I use Firefox as opposed to Chrome. > > **改善点**: I miss a lot of the extensions and customizations that I had access to in my old browser. I felt I could make it a lot more personal then than I can now with Firefox; it tries it's best and the library is large and ever growing, but it always feels like it's one step behind Chrome. > > Overall I love using Firefox because of its ease on my PC. Chrome put an intense strain on my set up when gaming, and that doesn't bode well when you're trying to stream\! Firefox and my games run like a dream side-by-side unless I open something really intensive like Tumblr\! ----- ### "My ride or die browser" — 4.0/5 > **B** | *2025年7月7日* | 非営利団体運営 | おすすめ評価：10.0/10 > > **良いポイント**: Firefox was the first to use tabbed browsing which is why I began with them in 1999. Since then, their product has remained awesome and it's my favorite first browser. The bookmarks toolbar works well, as does bookmark management of saving all of my bookmarks. Now that you can log in and have functionality across any system, it's just about perfect. > > **改善点**: When other, bigger entities started making tabbed browsers, I noticed that firefox functionality is sometimes difficult with some web sites. I don't believe this is a necessarily a firefox issue, but it does force me to use a secondary browser for a lot of sites. > > Firefox are true innovators and I have rewarded them for many years for being the first to do tabbed browsing. I like so many of the features they offer: The bookamarks, the history, passwords and autofill, and the bevy of extensions you can add to tailor your browsing experience. As others have copied their innovation, most browsers feel pretty much the same. But Firefox is my ride or die. ----- ### "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 Its just to outdated. Feels like im swimming in syrup, When trying to load pages. > > I wouldnt say I had a bad experience. I wouldnt say I had a good one either. Its just not my cup of tea. ----- ### "Firefox is very fast in browsing \!" — 5.0/5 > **Medina- Maldonado** | *2026年4月22日* | グラフィックデザイン | おすすめ評価：10.0/10 > > **良いポイント**: This Firefox browser is very fast for browsing. It has a high speed search engine. It has a great learning curve. Its customer service team is really trying. > > **改善点**: I do not have any cons for now on Firefox browser. I like using it so much due to its incredible high speed performance. > > My experience so far for Firefox has been amazing. The app is very fast in terms of browsing as it has a very high speed. I’m using it along with browsers like chrome, safari,Microsoft edge . ----- ### "A solid, well designed browser that has always come out on top." — 4.0/5 > **David** | *2025年5月27日* | 写真 | おすすめ評価：9.0/10 > > **良いポイント**: I especially like the fact that Firefox is a fast, security-oriented browser. By far its best feature is that on start-up, if it is set to open previous tabs, it doesn't automatically load tab contents, therefore its memory usage is well optimised. I'm yet to find any browser that does this so well. > > **改善点**: I don't have many complaints, but on the latest update it seems that AI has been forced upon the user in the new side-bar. However this is a minor complaint as it seems to be easily turned off. > > I've had many years experience with Firefox and have chosen it over all other alternatives many times. I hope this continues but time will tell. ----- ページ：1 / 23\ 次へ: [次ページ](https://www.capterra.jp/software/1012058/firefox?page=2) ## リンク - [Capterraで表示する](https://www.capterra.jp/software/1012058/firefox) ## このページは以下の言語で利用できます | ロケール | URL | | de | | | de-AT | | | de-CH | | | en | | | en-AE | | | en-AU | | | en-CA | | | en-GB | | | en-IE | | | en-IL | | | en-IN | | | en-NZ | | | en-SG | | | en-ZA | | | fr | | | fr-BE | | | fr-CA | | | fr-LU | | | ja | | | sv | | ----- ## 構造化データ
