Diễn đàn hỗ trợ Firefox

After moving home from college Firefox no longer works. I can open the browser, and it doesn’t crash, but websites will not load and I can’t search anything. The weather data says it is not available. I have tried everything. Uninstall and reinstall, reset, scanned for malware, reset DNS on my computer, cleared cache both on Firefox and on my pc. If I open up Chrome websites work fine. When I reset Firefox through the uninstall window, it works but if I close that and reopen it it is broken again. I am beyond frustrated and any guidance would be much appreciated.

I'm a decades long time Firefox user, and I always keep Firefox updated automatically to whatever is the current version. I've never had any substantial issues with Firefox in the past, but recently I've encountered some rather drastic issues.

Background: I'm ex-IT, so I tend to be ultra-conscientious about security and performance updates all across my system. I'm also highly alert for any signs that my system or apps might be compromised in any way.

Recently, I started noticing that I was unable to scroll with my keypad or keyboard on certain sub-windows and certain pop-ups in some web sites (not all). I could scroll these sub-windows/pop-ups only by touch screen, and until today that has always worked. I've been using this workaround, because I haven't had time to really look into the issue. Most sites worked fine, but many would not.

Today, however, I logged into what I know to be a legitimate web site, https://blueshieldca.com, for some important information, but this time I found I was unable to scroll ANYthing on the site using my keypad, keyboard, or touch screen. I could change pages through the on-site menus, but couldn't navigate further at all on any page. I can see that there is more information cut off at the bottom of the page, but I simply can't scroll the page to view it. I almost never use MS Edge browser, but I tried it today, and I'm not having the same problem using Edge.

I'm also having a slightly different, but similar (related?), Firefox issue with the typical cookie-settings-preferences prompts that appear initially on most web sites. Any time I try to arrow over the cookie prompts, they immediately disappear. I'm completely unable to accept, change, or set cookie preferences on any sites.

I've reviewed all my settings in Firefox and all the add-ons I use. In Firefox itself, I run the following extensions: Brave (default search), DuckDuckGo Privacy Essentials, Ghostery Private Search for Firefox, Malwarebytes Browser Guard, Privacy Badger, and Express VPN (disabled) - I do not run any browser-specific VPN, but I always use Nord VPN on my system. The configuration options are overwhelming, and in spite of investigating every avenue I can think of, I haven't been able to find either a cause or a fix. I'm sure hoping you guys can help me figure this out!

My system is Windows 11 Home (25H2), 64-Bit, on a DELL XPS 13, 32GB RAM, 1TB SSD drive (1/3 free), about 3 years old. In addition to the browser-specific security software mentioned above, I run Bitdefender Security. I haven't made any changes or specific updates to any apps that I can link to the inception of this problem.

Any ideas will be greatly appreciated!

All of a sudden I am unable to login to ingramspark.com It just keeps spinning but never gets past this page where I can enter my username and password info.

what it says on the tin. went data purging with ol reliable WinDirStat and found this absolute behemoth of a file in the profiles directory for firefox. its especially weird considering the entire Firefox directory itself is only 1.5GB with this menace taking 1.3 of it. I cant imagine that bookmarks, search history, passwords, the works takes up any more than about 300mb. so im wondering if im just stuck in the early days of data or if the file really is just that girthy.

I thought I used to be able to access browser history from much longer ago, either way I can no longer see any history longer ago than 29/10/2025 is there anyway for me to restore, download or access older history, or has it been permanently deleted? I do still have a back-up of 28/12/2025 but I don't know if or where that contains history. I'm looking for data between 2019-06-01 and 2024-08-21. Weird thing is I remember accessing search history that old before... though I'm not sure how if if it doesn't store it for that long. Any help would be appreciated.

I'm an 81 yr old white male. I've chosen Firefox as my browser for 2 reasons. I feel that it keeps me relatively safe, and I enjoy the stories you choose for the home page. The problem is that over the years,, many stories on the homepage require the reader to subscribe to the story's source in order to read it.

For a man my age, that's nuts.....subscribe just to read that one story.....not gonna do it. Consequently, I've had to look elsewhere that which I wish to read. I recommend that you research other periodicals that might allow reading without the required subscription.

It's very tricky the clone a FF profile, so I want to avoid that. (If there is a SIMPLE way to clone a FF profile, that would suffice. I have found no such animal.)

I would like to start Firefox by invoking different UserChrome.CSS files.

Is that possible?

I am not intereted in RUNNING both these simultaneously.

yes, I realize I could go through renaming and unrenaming files before starting FF to achieve this. But, I am I'm looking for a method using native FF resources.
