I can't open, delete, uninstall or update my Firefox on my laptop???

I dont have much Ram space on my computer - but am working on expanding it.

Yet, still - I can't open, delete, uninstall or update my Firefox on my laptop

Before purchasing, I verified that Mozilla VPN will work on Chromebook (shown on the FAQ page for the VPN). Since I can't install software on a Chromebook, how do I go about using Mozilla VPN on it?

I tried to open Firefox and a message appeared: "Couldn't load XPCOM". I uninstalled the program with Revo Uninstaller Pro and downloaded the latest version. I selected Run as Administrator but there is a message that says "Windows cannot have access to the selected device, path or file. Maybe you don't have access rights". However, I do have access rights. I have checked it multiple times. How can I install Firefox and see it work properly? Thanks

Κατέβασα το Firefox Installer.exe και προσπαθώ να κάνω εγκατάσταση με το Run as Administrator διότι για κάποιον λόγο δεν με αφήνει διαφορετικά, αν και έχω δικαιώματα διαχειριστή. Μου βγάζει όμως ένα παράθυρο το 7-Zip και μου λέει "Δεν επιτρέπεται η πρόσβαση".

Several days ago I backed up my hard drive, preparing to upgrade from W10 to W11. The upgrade was very slow and took a lot of time. Also, when I began to use W11, many of the programs, including Firefox, were slow to load and slow to run. Finally, I decided to try a reinstall of W11, hoping for an improvement. For this second try, I decide to use the option that eliminated programs that, over the years, I had downloaded onto my computer, such as Adobe Reader, Glary Utilities, and Firefox. For whatever reason, this second installation of W11 took less time and programs like Adobe and Glary worked almost as well as before. (They performed a little better on W10.) But not Firefox! Firefox wouldn’t run at all. I then deleted Firefox, using Revo Uninstaller. My next step was to download another copy of Firefox, from the Mozilla website. The result was the error message I have seen on many postings on this website:

Profile Missing Your Firefox profile cannot be loaded. It may be missing or inaccessible.

As of this writing, the path C:\Users\rsuth\AppData\Roaming\Mozilla\Firefox\Profiles\ leads to two folders, both dated 11/11/2024: 0dppjrfa.default contains one file, times.json, dated 8/11/2020 and ru82tlj5.default-release, containing 97 items, files and folders, most – but not all - of the files dated 11/11/2024.

On my desktop is a folder Firefox Bookmarks. Inside is Mozilla/Firefox/Profiles/xh22l03a.Default User It contains 79 items, files and folders, mostly dated 7/16/2023

I have used Firefox for many years. It contains links to many handy and valuable websites. I hope that someone who has read this account will be able to direct me to a solution that will allow me to recover my previous Firefox and all the all the important information it contains. And, if that happens, then I will try to do something similar with my lost Thunderbird. Thanks for reading.

Dear Mozilla Firefox Team,

I hope this message finds you well. I am a long-time user of Firefox and have greatly enjoyed the browser for its speed, security, and user-friendly interface. However, I recently encountered an issue where the latest update seems to be incompatible with my system.

As a user with a low-end system, I sincerely request that future updates consider compatibility with older or less powerful hardware. Firefox has always stood out for its accessibility, and I believe that supporting a wider range of devices would further enhance the browser’s appeal to users like me.

I would be grateful if there could be an option or version of Firefox optimized for systems with limited resources. Thank you for your time, and I look forward to your response.

I have manually installed multiple older versions of Firefox for Desktop (Windows 10), as I am translating KB articles and sometimes need any of the twenty latest versions to get screenshots in my language for the translated articles.

When an older version becomes superfluous, I would like to uninstall it from my computer, but that does not work. Even though I see all the older Firefox versions listed in Windows Applications & Features and each of them has an Uninstall button (and a helper.exe file in the uninstall folder in the installation folder each of the versions), the only "action" I see is that I get a warning that the Firefox Helper application is about to make change to the content of my hard drive, and will I allow that? The pop-up asking if I want to refresh Firefox instead of uninstalling, it does NOT appear.

The only time I get a proper response, i.e the Refresh-instead-of-uninstall? pop-up, is when I initiate uninstall of the latest current version of Firefox, in my case Fx132.0.2.

Have anyone else come across this problem?

problem will have one forever until you stop claiming new update no not adding new stupid things like weather

you just know we will find make add on or about config find how to remove disable your new crappy no good wasted effort weather you added all your new adding that ill just turn every update ability off in firefox not trust you will be posting these claims your updates not real junk way to add stupid things not needed waste effort ever make it let me be in charge there for one day ill fire every firefox builder had any part of making claim update really just adds junk just know ill check for firefox updates every 6 months otherwise be turned off you not trustworthy these actions may lose millions of firefox users may go different keep playing about updates update make browser go up in level not add new stuff like weather that unneeded unwanted waste of time to make it why make something added to new update let those things be if someone wants a addon for weather

If I have to restart my computers when I am in the middle of working because Firefox won't work unless I do, I will find another browser. And yes, I have it set to only update when the computer is not being used, but obviously that does work. Maybe give me the option to set a time to restart?! Like the middle of the night as opposed to the middle of a working day!!!!!!!!!!!!!!!!! Really???????????
