Diễn đàn hỗ trợ Firefox

Chase bank online is now requiring a later version of Firefox than my Mac will support. I currently have Firefox version 115.30.0esr. Now I am unable to access my account on line to see purchases. What is my work around? I thought there was software that could be installed to "spoof" chase into thinking I had a later version of Firefox. Both of our computers are from 2011 and 2012 so neither one will accept the latest version of Firefox. Many thanks in advance for any advice.

A week ago I got a BSOD that ruined settings of most of my extensions and most likely some of Firefox's settings too (at least it erased my custom findbar.matchdiacritics value, but probably not just that). After that I moved Firefox's folder and re-installed it. I also created a new profile. The 2 profiles are synced. Because of that, the new profile got (almost) all the extensions from the old one automatically. Then, I decided to do a clean install of those extensions (the reason why is a story for another ticket). So, while both profiles were opened, I removed one extension in the new profile, waited for a bit and checked the old one to see if it got removed from there too. At first it wasn't, so I thought they are not synced (anymore). Yeah, sure, but once I removed all extensions from the new one, the old one woke up and removed all extensions from there too. Great! Awesome! Loved it wholeheartedly! It really had to wait until I removed them all, didn't it? Anyway, I had a backup of my old profile, so I restored my extensions and their settings on both profiles eventually. So now I have clean installs of Firefox and extensions. Back to the issue. I can't load Steam pages (at least store.steampowered and steamcommunity) normally anymore. They load forever, and if the blue dot eventually stops moving (after an insane amount of time), it's either a plain white screen, or badly loaded page with most images missing.

• Edge loads them just fine
• Steam client loads them just fine.
• If I turn on VPN plugin (I use Browsec), then it works. It's like that in both old and new profile. That's why I mentioned that funny little story before.
• Tried Troubleshoot Mode, didn't help.
• Tried to selectively disable some extensions, same.
• Obviously tried to remove cookies, Ctrl + F5 and whatnot. Btw, if I clean everything and try to load it, then it's (most likely?) a white page, but if I turn the VPN on and load it first, and then turn it off and reload it, then it will look a bit better, but still will load forever with some media missing. (Which kinda make sense since something was already cached.)
• Tried to change proxy settings from “Use system proxy settings” to “No proxy” and “Auto-detect proxy settings for this network”, nah-ah.
• Tried to disable DNS in Firefox's settings, no siree.
• The console throws different warning and errors every time (that are probably even unrelated). Or none at all.
• Probably tried something I already forgot about.

Also, it seems the culprit is actually Akamai (it's where the Steam stores its media) or whatever is preventing reaching it. Because it often shows something like “Waiting for community.akamai.steamstatic.com...” in the status bar for a long time. It seems like the problem is within Firefox's settings, and it also looks like settings aren't synced across profiles (or at least some aren't, I definitely had to configure them on the new profile manually). Anyway, I am out of ideas and my butthurt thrust is about to deliver me to Uranus. Thanks for your attention!

Does Firefox provide firewall and/or security programs for my computer running on Windows 7? I cannot buy a new computer and want to make sure I am protected - my updates are up to date and I have had faith in Firefox. Otherwise, can I use an ADD-on to do the job? Please advise. thank you very much

I have been unable to sign into my bank account online (on this computer) . Been prompted to update my browser (Chrome, Safari, Forefox, Microsoft Edge), I checked my Firefox version, says up to date. Still unable to access. Spent hours frustrated. Please help. thank you so much

Howdy! 2nd time in 2 weeks sign in has not worked on certain websites like E*Trade. Must switch to data mining options like Chrome. What is up? My Mozilla and Firefox do not allow User Name & Password to work even with destination URL's support team's help.

Dear Mozilla Team,

I’ve been a loyal Firefox user for over 15 years, and it’s been my go-to browser for both personal and work-related tasks. However, recently I’ve encountered persistent issues where several websites—especially work-related ones—have stopped functioning properly. I’ve tried troubleshooting steps like clearing the cache, allowing cookies, and disabling tracking protections, but the problems persist.

Reluctantly, I switched to Google Chrome as it currently offers better stability, but it’s been hard to abandon Firefox after so many years. I truly value Mozilla’s mission and privacy-focused approach, and I’d love to return if these issues are addressed.

Could you please look into these compatibility problems? I’d appreciate any guidance or updates on fixes. Thank you for your hard work—I hope to support Firefox again soon.

Best regards, Gustavo

Hi

Recently when i try to sign into my outlook accounts using the option password, says "you've tried to sign in too many times with an incorrect password?" i have to ask to send a link to another email address to sign in. I have no problem signing in on other platforms, just Firefox. I have tried safe mode clear cache and still it doesn't let me sign in using my password? Assistance to resolve this would be appreciated. Thank you

Bank website keeps telling me I need to update my browser. I did update and am currently running 115.30.0esr. What is causing the website to not recognize the update?

Today is 11-12-2025. After the last update a few days ago, many of my websites would not load up on firefox and when try on Edge or Chrome, they would work perfectly. I did a recovery back to 10-31-2025 and everything worked fine. Now I am afraid to do another update until I know what is going on. What would you suggest? Thanks,

Hi, I'm using Firefox 142 on Ubuntu 24.04. It's a fresh install. I cannot sign in icloud.com with Firefox even though it works with other browsers like Brave. I deleted all cookies and site data and disabled extensions (KeePassXC). It doesn't help. I tried in new private window. No success. I copy my password from a password manager, so, no, I haven't mistyped it.

Here's what I do:

1. Open Firefox and go to icloud.com
2. Click on the "Sign In" button
3. Enter my Apple-ID and click on the arrow on the right end of the "Email or Phone Number" field

At this point Brave behaves differently than Firefox. See below for how Brave behaves.

Firefox: -> A "Password" field appears (no buttons "Continue with Password" and "Sign in with Passkey")

1. Enter my password and click on the arrow on the right end of the "Password" field

-> Error message "Failed to verify your identity. Try again" appears. See icloud.png

Brave: -> Two buttons "Continue with Password" and "Sign in with Passkey" appear. See icloud-with-brave.png

1. Click on button "Continue with Password"

-> A "Password" field appears.

1. Enter my password and click on the arrow on the right end of the "Password" field

-> 2FA code is sent to my iPhone -> "Two-Factor Authentication" form opens... etc. complete sign in successfully

Please help!

Unfortunately I cannot attach the HAR file from the login sequence because the password is included. However, I attached some screenshots from the Web Developer Tools. It seems to me that the login flow with Firefox is broken. I can't tell who's to blame, Apple of Firefox. The error message with Firefox is always the same, no matter whether I enter the correct password or rubbish. In Brave, however, there is a more precise error message when I enter a bad password. See icloud-with-brave-wrong-password.png

Since update to latest version of Firefox, I cannot access content on Facebook. All I get after long wait is the blank screen with the Facebook logo in the middle and Meta logo at the bottom. No problem before update. Other sites seem OK but take much longer to load. I can get Facebook with MS Edge. I'm using Windows 10 on PC.
