Diễn đàn hỗ trợ Firefox

Several weeks ago, I was attempting to upgrade from Windows 10 to Windows 11. In the process, I deleted Firefox (using Revo Uninstaller) and then reinstalled it, downloading it from the Mozilla website. Unfortunately, it didn’t run, giving me, at different attempts, different error messages. In the time since then, I have read many suggestions from many different websites and I have tried some of these suggestions, all with no success – until today. I have just completed the suggestions made on https://support.mozilla.org/en-US/questions/1327628 and Firefox is now back, working. I am happy and grateful, but not finished. None of my personal data came with the currently functioning version of Firefox. Since the re-emergence of Firefox, I have been reading several websites dealing with copy, backup and restore of my Firefox profile. Right now, the path C:\Users\rsuth\AppData\Roaming\Mozilla\Firefox\Profiles\ shows 5 folders: Two of the folders show 11/11/24 as the date modified (probably the date of the download from Mozilla). The folder 0dppjrfa.default contains one file, times.json, dated 8/11/2020. The other folder, ru82tlj5.default-release, has 97 items, most dated 11/11/2024. The remaining three folders are all dated 12/2/24 (today, as I write this). One folder’s name ends .default, the second name ends .default-release, and the third name ends .default-release-thirteen digits. The question that I am asking here is what do I do next to, hopefully, bring back the personal date I had with Firefox before my updating to Windows 11. Should I delete the folders dated 12/2/24? What, if anything, is the significance of the folder whose name ends in 13 digits? I’m hoping someone will be able to tell me how to fix these Firefox problems. And if I can, then I hope to be able to do something similar to help me bring back Thunderbird as well. Thunderbird became unfunctioning at the same time as Firefox. Thank you.

Every time I wake my computer up or start it, I get the attached error about a profile not being compatible. I did switch to the ESR release channel a while back, but I deleted the old profiles; the folder is gone and the profile manager shows only the ESR profile. I have also tried to prevent firefox from starting on startup, but it keeps happening. Does anyone know how to prevent this error from happening, or have any ideas of how to investigate what's going on further?

Everytime I load Firefox the bookmarks sidebar is not shown.

Navigating thus View => Sidebar => Bookmarks I can bring it up. It will stay visible for the whole of my browser session. However, after I've closed this session and started another. the bookmark sidebar is missing again.

How can I make the bookmarks sidr be available all the time?

FF 127.0.2 OS Windows 11 Pro v 24H2 Build(26100.994).

I've changed primary email some time ago and wanted to login using a new device. However, login fails with "Incorrect email case" and response contains my old email under "errors[0].extensions". After that, there is another request doing login with old email, which seem to be successful, however the whole operation fail and page only shows "Something went wrong. Please close this tab and try again.". Trying to login directly with an old email leads to "Primary account email required for sign-in" error. Please assist.

I just installed Firefox. What I noticed right away while using it was that fonts were very blurry/hard to read on all web pages, and even in firefox's menus and URL bar.

I attached two pictures, one is a screenshot in Firefox, and the other is a screenshot in Brave. (All chromium web browsers I have tried don't have firefox's font problem)

I have a problem on the aliexpress website. (in other browsers everything works fine) When I open tabs with goods on aliexpress. and start switching between them, then at the moment of switching to another tab, my previous tab itself is updated and opens the main page. And there is no way to even press the “Back” button. The browser seems to reload the page completely. The chatgpt was unable to find a solution. All hope is on you. There are no errors. It's just that the aliexpress page reloads by itself when I switch to any other tab.

I don't know what happened, I haven't been tinkering with anything. This happens for every video, not just this one. I've also posted my addons as well, in case that helps with anything.

A few days ago I changed to a new computer.

On my old Windows 11 computer in Firefox I could sign in with my [edited] @gmail account to my Blogger blog, see the New Posts page, edit my posts, post new posts and see the sign out option.

But on my new Windows 11 computer in Firefox I can sign in with my [edited] @gmail account to my Blogger blog, see the New Posts page, but I can't edit my posts. I am signed in but Firefox doesn't show the sign out option.

Whereas on my new computer in Chrome I can sign in with my [edited] @gmail account to my Blogger blog, see the New Posts page, edit my posts, post new posts, and see the sign out option. As always.

In Firefox it says there is something wrong with my [edited] @gmail account and to refresh it or change to another account. I don't now how to refresh it and changing to another Gmail won't work. But it lets me in to my blog's New Posts page!

How can I in Firefox on my new computer edit my posts and see the sign out option, as before and as always in Chrome?

I recently added the "Display Autoplay" extension. I can't seem to figure out how to get the icon to show in the tool bar. See Attached acreen shot. That's assuming that this extension icon can be added to the tool bar. I look forward to anyone's comments. Thanks

WSJ did some sort of update and now things are broken in the regula browser. I've tried disabling all my extensions, putting multiple sites on the cookies exceptions list and turning off protection in regular mode and it does not work. Private Browsing works out of the box no issues.

The main way to know if you have issues is do you see the stock ticker near the top of the webpage, your name with account info, and some drop down windows. The Live Update sub-websites are broken. I think WSJ on some sites like those thinks I'm not logged in or can't verify I'm logged in.

Its weird. I've had similar things on FireFox before, what is regular mode doing? Why does Private browsing work? Can I somehow "force" the same settings in a regular windows on a per Website basis? This doesn't seem possible at this point.

Hi,

am running firefox 127.0.1 on a windows 11 desktop. Numerous sites that use a captcha to login fail. In other words, the captcha never loads and I cannot login to those sites. Such sites include teamfaderpro, Coursera, and bandcamp. All logins fail as the captcha is required to be passed prior to logging in, but the captcha never appears and so when I try to log in, nothing happens and I cannot login.

I have tried the above same sites on the Edge browser and have no such issue, the captcha shows and I can login.

Just FYI, the agent switcher setting change recommended by others previously is not suitable. When I tried that fix I was unable to access a considerable percentage of the internet due to some cloudflare issue, so the agent switcher setting is not an option. So far, I have tried all recommended settings to fix this issue and nothing has worked.

I am surprised no one else is having this issue.

Any help is appreciated, or at least inform google/mozilla about this issue as it has been ongoing (on and off) for me for many months. And yes, this problem is persistent for me at the moment, it remains despite rebooting windows, despite clearing cookies and cache (which I have set to automatically delete when exiting firefox).

When I startup FireFox, it takes ~15 seconds to show me an page. After loading, it works normal and loads pages within a second, until I completely close the browser, and then the first page again takes ~15 seconds. I've been having this issue for the past few months.

- I tried disabling all my addons - Launched FireFox in troubleshoot mode - Deleted everything in DataReporting\Archived folder - Cleaned out History/Cookies and site data/Temporary cached files and pages - Tried both Default and Max protection for DNS over HTTPS - FireFox is allowed in Windows Defender firewall - Tried setting 'browser.cache.disk.enable' to FALSE - Tried changing 'Enable HTTPS-Only Mode in all windows' to 'Don’t enable HTTPS-Only Mode' - Windows and FireFox are up-to-date

None of the above saw any improvement in loading time.

Hi.

How come there is no option to turn off "Firefox Translation"? I speak three languages and every time I visit foreign web site, Firefox suggest translation to me. It's annoying.

I recently updated to Firefox 131.0.3, having signed out of my Firefox/Mozilla account. Now I am trying to sign back in. After a seemingly successful sign-in (with email and pw, followed by "authorization code"), I'm taken to my account page. Scrolling down to Connected Services, I can see a recognizable account name (my Windows 11 user name and the name I've assigned to my computer). But looking up at the account button at the top right of Firefox, I see a small yellow triangle. Clicking on the button, I'm told "Account disconnected." (Remember, I'm currently looking at my account page, which says I'm connected.)

So I try to log in again. I give email address and password, and authorization code, and I'm in again. Now I see an addtional account connected, "Firefox 131, Windows 10" (remember, I'm using Windows 11).

So looking up again to the upper right at the account button, I see the yellow triangle, and clicking tells me once more that I'm disconnected, even though I have my account page open in front of me.

All of this, of course, prevents me from having access to the sync function. I've been through this circle several times with the same strange results.

Anyone have any idea what' going on.

Screenshot attached.

Thanks! Lance

Whenever I try to sign into any Google site whether it is Gmail, Google, Youtube. or even signing into a site with a google account like Pinterest I get sent to the google help page taking about clearing cache & cookies. Even from there when i click sign in it just refreshes the page never actually taking me to the sign in page.

my extensions got unpinned and the new tab button is gone, the tab overview is gone, the extension button is to the left of the address bar, the back and forward buttons are to the left of the address bar, the back and forward button are swapped, WHY.

In the screenshot i pinned the 3 extesions i use again, they were unpinned before

After a windows update I get the following message when I try to open Firefox: The procedure entry point ?ToLogLevel@mozilla@@VA?AW4LogLevel@1@H@Z could not be located in the dynamic link library C:ProgramFiles\Mozilla Firefox\xul.dll Then I get Couldn't load XPCOM

I tried uninstalling firefox but it just hung. I restored it to before the windows update but still got the same message

When I receive an email that has a link, Firefox opens without any of my settings. This also happens with Firefox pop-ups, which indicate I don't have certain products, such as Web Advisor, even though I do.

I guess the first question is why a new iteration of Firefox is opened when I already have it running.
