Firefox 技術支援討論區

I am having a new problem with < https://www.citi.com/ > I have used this website for years with Ffox with noo problem. What I experience now is that I can login and use it just fine, i.e. access any of its links, except if I try to use the Virtual Credit Card (VCC) feature. To use that feature you login, select VCC, which takes you to a new page, on which you launch a popup that generates the VC. My issue is that I login, select he VCC page, but instead it takes me back to the main screen to login again. This circular problem can continue as many times as I try it. Below I list my equipment and trouble shooting steps.

I am using a win10 PC running 21H1 and the current version of FFox. I have a Malwarebytes Browser Guard installed (MB).

1. I tried the login on my Surface GO running win10 Home Edition and no MB installed. It worked fine. 2. I tried to login with Chrome and Edge on my PC, neither with the MB browser guard, and they work fine. 3. I have had the MB installed for quite some time and the Citi site always worked fine. Nevertheless I disabled it. That made no difference. 4. Next I clicked the FFox shield and disabled the Enhance Tracking protection. No difference. 5. I deleted all cookies and cache info related to citi, amounting to 10 entries. That made no difference. 6. I deleted all cookies and cache totally. Now I was able to log in and go to the VCC page. 7. I closed out of the citi site and tried to re login. The problem reappeared. 8. I deleted all cookies and cache yet again, closed FFox, launched it again, tried the Citi site and it worked fine. 9. I logged out of citi, tried to log in again, and once more it did not work.

Any ideas?

Dear Mozilla Support,

After some update (I think from 89.0.0 version of Mozilla Firefox - this version with new looks of tabs) I notice flickering on the tab when I loading website or refresh website. This looks very strange. Like I said I dindn't notice any issue with flickering on previous Mozilla Firefox versions. Only with these new versions with new look of the tabs. I didn't remember if it was 89.0.0 version or 90.0.0 version. I don't know if it is problem with the machine but I didn't notice this issue on another computer with 90.0.2 Firefox version but with Windows 10 OS. I also noticed this issue with Firefox 90.0.0.2 with Windows 7 OS on another computer so I don't know if this is problem with two computers or Firefox itself. Can you help me?

Yours faithfully, Piotr

Somehow firefox is trying to open (by itself) a page that is sytematically blocked by SOPHOS antivirus. It is a malware or a setting in Firefox causing this? the site is: flashvd.net/.well-known/http-opportunistic. This is happening only when firefox is running. thanks

In Firefox 90.0.1 (64bit) Windows 10, the text in certain web pages, include the main news page of bbc.com has become completely invisible (no width but they are there).

I have disabled all extensions but the problem is still there. I have also tried turning off graphics acceleration but the problem still persisted.

However, if I start Firefox in Safe Mode then the problem goes away. How should I pin point the cause of the issue?

I've been using site https://mail.aol.com/webmail-std/en-us/suite for years to log in to AOL email for years and now, with Firefox v90, it takes over 2 minutes to load. It takes only a couple seconds with the Edge browser. I've tried troubleshooting mode, a refresh and a complete re-installation without any improvement. This never happened in previous versions of Firefox.

Any help is appreciated, Gary S.

I'd like to have, in my one firefox account, a 'private' profile with my private life bookmarks and a 'work' profile with my work life bookmarks. However, this doesn't seem to work. I open firefox with work profile and see my work bookmarks, then I close and reopen with private profile and see my private bookmarks, then I close and reopen again with work profile and now I still see my private bookmarks instead of my work bookmarks. Firefox just unsolicitedly takes the private bookmarks over to the work profile. This can't be how it's supposed to be, right? Because what would be the point of having different profiles? I hope you can help me with this.

I'm currently in my vacation home and I don't have home internet here. I'm connecting through my mobile phone using limited mobile data. and I selected not to download updates because it keeps updating itself like twice in a week and every MB counts in limited data plans especially if it's just 4 GB total for each month.

But now every time I open the firefox it showing download latest update popup like an annoying virus on the top right corner where 3 horizontal lines are located.

I checked the internet and previously this was an option in it's settings. Then this option removed and only hidden behind the about:config . and now it's completely removed from about:config either.

The only reason I switched from chrome to firefox was because google became an absolute dictator lately and all it's changes was to limit down my accessibility. I switched to firefox becuse it doesn't backstab it's users and they give the choice to it's users rather than dictating it like dictators. So did I make a mistake switching to firefox? Is firefox becoming just like chrome now? or is there (hoping so much) and option given us to turn off the notifications as well?

I had an issue where when I tried to open firefox I received an error that said ""A copy of Firefox is already open. Only one copy of Firefox can be open at a time". After looking at some other support articles I came across this article that appeared to fix the issue after entering a command in terminal https://support.mozilla.org/bm/questions/1254772, and I guess I deleted the wrong version because after being able to reopen my browser I had none of my saved bookmarks, extensions, history, or any other account info.

Is there any way I can recover my lost browser info or am I just completely SOL?

Update installed taking Firefox to V90.0, and the colors of the bookmarked sites changed from blue to red, as well the downloads changed from blue to red. Not a big deal but I find the red a bit too bright. How do I change these back to blue? Thank you.

I just upgraded from FF 89 to FF 90 (on Ubuntu) and the drop down menus (accessed on right-click) are now transparent. I have changed the theme, changed my desktop theme, started FF in troubleshoot mode, disabled acceceration in about:config, and it makes no difference, the menus are still transparent. This makes it difficult to use the browser.

Is this fixable or is it a bug in the latest release?

Hello. Sorry, but I couldn't get any more proper place to report this problem. On one of Mozilla Bugzilla bugreports is present my email adress. I don't see any possibility to edit the post and I can't get in contact with anyone from Mozilla Bugzilla, who could remove my email. What can I do to delete my email adress from the public bug report? Best regards.

I get black flashing box's while having two different windows of firefox up upon moving my mouse the box's appaeare more frequently and get worse, I've disabled ALL add-on's and themes including hardware accelerations as per other threads with the same issue however mine persists, however when I enable safemode the problem stops. I've disabled all Add-on's and themes and even done the firefox restart view the File Menu and done a clean re-install on my Graphics Cards and it still persists. Any help would be appreciated.

Browser has updated to 90.0.1 from 90 today. I cannot change the checkmarked box in front of the: 'Delete cookies and site data when Firefox is closed. Currently stuck as being checked. Restarting browser did not work.

Hi all, i'm having an issue where everytime i start the browser, a facebook "tile" shows up in the first empty square in the main page shortcuts section, i disabled the sponsored shortcuts, and removed it, but it keeps coming back, no idea what to do.

When I try to reset the primary password, I can get a new password - the only problem is that this new password is not accepted when I try set a new login into a web site. It looks like there are two different passwords: one for "Firefox Accounts" and one for "Firefox Logins". How to reset the latter one when they differ. There is a kind of deadly embrace! Not to forget that the access to the support can be on the same email address with a totally different password.

Is a start from scratch with a completely new profile a possible solution?

Hello,

https://addons.mozilla.org/en-US/firefox/addon/epubreader/?utm_source=addons.mozilla.org&utm_medium=referral&utm_content=search

Installed on 90.0.2 (64-bit).

Works fine when opening an EPUB from the browser but if I double click on an EPUB file it opens multiple tabs & will not stop, has anyone else encountered this & been able to fix it?

Windows 10 Asus laptop, no issues with anythng else, am wondering if Windows 10 App settings could have anything to do with it but have not been able to find a way to disable default settings completely? Alternately is there something I can do via about:config on Firefox to alter this?

Ideally I don't want to have to uninstall Firefox completely in the hopes of seeing if a fresh install will stop this issue arising.

Thanks
