    Good design but it consumes a lot of computer capacity.

    Date: Mar 04 2021
    Summary

    From 1 to 5, I give Mozilla Firefox a 2. This is a browser that must fully accommodate your work structure in order to be profitable for a common user. This browser consumes a lot of computer capacity and causes it too slow when searching in more than 10 tabs simultaneously, I hope Mozilla will focus more on improving its fluency and ensuring that it does not consume so much computer capacity, instead of concentrating on improving the design.

    Positive

    Mozilla Firefox is considered by me to be one of the slowest browsers that I have used on my computer and on my cell phone. Previously, it was a very fluent browser, Internet searches were very fast and it was software that did not consume a lot of capacity from my computer, however, over time many updates were inserted which made my experience in Mozilla, become every slower and slower to the point of not being able to use it comfortably. One of the things that I liked about this platform is that its interface is quite attractive, the interface was really one of the things that kept me the most as a Mozilla user, since I felt very comfortable with such an attractive interface. he liked the way he could download all kinds of extensions smoothly, he could always open extensions in just a few seconds without any complications.

    Negative

    There are many negative factors which made me less and less like Mozilla Firefox and its general performance. This explorer as I mentioned earlier, consumes too much capacity of the computer, the more they added updates, the explorer consumed more capacity of my computer's RAM card and caused the computer to become too slow during the use of this explorer. In addition, another negative factor that made me stop using Mozilla is that when I opened a large number of tabs (approximately 10) the browser became even slower, as if it could not support the number of tabs that were open at that time. My recommendation for people who use this browser is to look for a better alternative, one that is capable of offering them a better, much more fluid experience for Internet searches.

    I keep this efficient browser by default

    Date: Feb 23 2021
    Summary

    For me it is the best browser thanks to its versatility, easy use and great security. I hope they improve the consumption aspect or that it can at least be modified manually like the Opera browser.

    Positive

    Security is very important to me and Firefox provides the necessary tools to be able to stay safe within the websites that I browse. It is customizable, from the themes to the position of the icons of the options that Firefox brings. I can download the installer offline, not like other browsers that only allow an installation with a mandatory internet connection. It is very easy to update and always has new features. It notifies before closing the browser that if you are sure to close it, this helps me a lot in case of making the wrong button on the window.

    Negative

    Since the new updates Firefox has become as heavy as Chrome, I am not talking about the weight of the installation, I am talking about the resources it consumes from my desktop. I remember that I selected Firefox as the main browser because of how fast and how few resources it consumed. The extensions for Firefox do not work very well if they are not updated together with this browser, which is not the case with Chrome that its extensions continue to work regardless of the browser version.

    I have not had a great experience with Mozilla.

    Date: Mar 03 2021
    Summary

    The overall experience I've had with Mozilla Firefox has been bad. I think this computer needs to make a lot of improvements in order to be profitable and be used as the default browser. Currently Mozilla Firefox must make several improvements in the extension system, in the theme store and also in the automatic update system. It should be noted that the speed with which Mozilla Firefox works and the speed with which it performs searches is impressive, I cannot complain about that because I have had a good experience in Internet searches, however, my experience as a user was bad, I think that many improvements are needed which can optimize the user experience and user comfort.

    Positive

    Mozilla Firefox has always had a very good interface, the design of this browser is really unique, the colors it has and the browser sections are very well organized. What I liked the most about Mozilla Firefox is that the opening of the browser is really fast, it takes absolutely no time to open successfully, in addition, this browser has the ability to not generate so much consumption on the computer's RAM card, it is a browser that does not consume as much computer capacity and this helps to always have a smooth experience when it comes to searching for things on the internet.

    Negative

    There are several things that I have not liked about Mozilla Firefox. Although I really liked its interface and how complete its sections are, I consider that this is a browser that still has a long way to go to beat the competition. The most prominent negative factors were:

    - Mozilla Firefox makes constant updates. When an update is available, and the user tries to open the browser, they will not be able to, as the update will start automatically and there is no way around this. I consider that this limits the user a lot, since if Mozilla is their default browser, and they are not allowed access just because there is an update, this limits the user's navigation.
    - The extensions that are added to Mozilla Firefox take a long time to start, and also, the design of the extensions is totally different. The extensions do not have that design as optimized as in other browsers, but the colors are more saturated, in addition, the extensions take a long time to start correctly.
    - The theme store is not that complete. Currently very similar themes are offered that can be added to the browser, this means that there is very little variety in the themes that can be added to the browser.

    Good alternative browser for privacy

    Date: Aug 12 2021
    Summary

    This is a great browser, very customizable, and an easy recommendation over chrome/edge. Wish it didn't get bulky over time.

    Positive

    This browser has its own addon store, isn't bulky to begin with, touts many privacy features, and can be customized for an even further privacy-centric focus.

    Negative

    The browser does become resource-heavy after the good add-ons are ... added on. Because its not built on Chromium, they lag behind in so e of the features evident in chrome and other chromium browsers, not on firefox's teams' fault, but because google can 'sabotage' by making it harder for firefox to implement their tools in their browsers.

    Less used, less bloat, solid browsing

    Date: Sep 13 2021
    Summary

    Firefox is more niche than its competitor but it deserves just as much praise, if not more. The quality of its execution is far too often understated.

    Positive

    Less of a memory hog compared to industry leaders, lots of built in privacy protection. Pockets is a wonderful system.

    Negative

    Being lesser of a market leader, there is less app support. Still some memory bloat.
