Firefox 社群討論區

Over the past six weeks I have had two failures of Firefox [running current version 146.0 (aarch64)] in completing CC payment processes -- at least one involved updating an expired car, I can't recall if the other involved such a change or just entering a card.

I am using Firefox on a mac mini M4 Pro running macOS Sequoia 15.7.2 (up to date, fully supported, but not Tahoe the recently released new version of macOS). I am running Firefox with 4 extensions -- 1 Password, Print Friendly, Raindrop.io, and Authenticator. None were being actively used during these incidents.

In both cases when I switched to Safari and opened the sites, I was able to successfully complete the CC changes and payments. So it does not appear to be related to a problem in my internet connection.

My questions are: a) has anyone had a similar experience with Firefox

     -- particularly incidents related to online financial transactions

b) if so, have you found a solution c) regardless, do you have any suggestions about the cause of the problem or changes to try

Otherwise, my experience with Firefox has been excellent and I am very happy with it, but this is obviously a frustrating and time-consuming problem.

I have reported it to Firefox -- the response was that they will look into it but that my next step should to ask "the community" here.

My thanks in advance for any help or suggestions.

Hi Mozilla I hav got a problem with Firefox on Kubuntu 24.04.3. Everytime the computer is restarted Firefox crashes the first time it's started. That's not a big problem, starting Firefox again don't take long. But the problems is exceeding. If i start Firefox by clicking a link in a mail in Thunderbird. And Firefox has not yet been started, It crashes, but now it's also invaliding the Task bar on the screen where Firefox was started. Invaliding means that I cannot start apps from that screens taskbar, and the clock has stalled, none of the tools works etc. The only possibility solution I have been able to figure out, is restart (It's like going back to Win 98). Sometimes I am able to start a app from that invalid taskbar. But it's not the one app that i clicked on. Even though I can trigger it via Thunderbird, the invaliding of the taskbar will occur after a while. And I have to restart. I am not sure if this is the right place to post. But Firefox is always involved, but maybe Thunderbird or Ubuntu was the right place? Every time Firefox crashes there is send a crash report to Mozilla, but is has been going on for a while, so i guess that nobody is looking at the crash report. If I use Chromium instead of Firefox I don't see the problem.

I get screen tearing on videos or when i scroll on any website. Only happens on Firefox, I've tested Chrome, Edge, Opera.

Smooth Scrolling is Off. Hardware Acceleration is Off. I've tried toggling "gfx.font_rendering.directwrite.force-enabled" Firefox is up to date.

None of this has helped.

Emojis do not show on Firefox 146 on macOS. I downgraded to 145.0.2 and they do show, so it seems related to Firefox 146.

I have macOS 26.2 running in both test cases.

Hi,

I use Firefox app in macos, android and ipados. The bookmarks across them are not synching automatically. I need to press sync manuelly to do. All apps are updated, all settings look fine. Please help me synch bookmarks across platforms. Thanks a lot.

Hello! See the screenshot please: so, I downloaded à pay-bill, with Firefox (under ubuntu), in private navigation, and I get the file with a padlock-symbol at the end. What means that? What means that for me (on my computer), what means that for à friend, when I sent him the pdt-file (can he open it?). Nota: I understood that I can choose between "delete downloads when closing the privat window" or not. And I choosed not to delete them (but there appears this padlock-symbol). Thanks for your help!

146.0 (64-bit) Windows 11 December 11, 2025 Turned on computer this am, Firefox webpage popped up telling me about what is in it's future but now my side bar is black print on really dark background. Help!

My browser is not working as it should. Several sites do not work anymore and the browser keeps crashing. I'd like to refresh the browser, but the button is missing. I tried going to troubleshooting mode, but the button is not there either.

Not sure if uninstalling would do the same thing? Just not sure what is the best way to refresh. Thanks for any help!

I am using Firefox on Windows 11, in the process of switching from Chrome.

I run Cockpit (https://cockpit-project.org/) on web servers that I manage, and when I log into it on Firefox the screen flickers constantly, making it unusable.

There is no issue with any other web sites I have visited, and I can still use Cockpit when in Chrome. So ay suggestions on how to troubleshoot and resolve the issue with Cockpit and Firefox?

Hi, Since three or four months, whenever I log into Outlook live, either on Mac or Windows PC, I get a security warning saying that the information will not be secure (Please see attachment.) When I log into the same account, from Edge for example, I do not get the warning popup. I really enjoy using Firefox and would love to continue but this case is worrying me a bit. Any idea to help? Thank you very much, Mathieu B.

The last 2 days i have had problems signing into my Aliexpress account. The site has told me it is temporarily unavailable, then that the server is taking too long and now that parental controls have been used.

I am 68. I don't need or use my computer for sites that require parental control.

I just bought my boyfriend a new iMac. We are having trouble loading many sites and platforms using the latest Firefox browser. The list is growing but includes Facebook, Meetup, Wikipedia, chess.com, nytimes.com - in all cases, rather than a login screen, we get an error message or a home page loads with no access to other pages or login area. I've cleared the cache, restarted, tried going directly to the site to log in, but nothing works. Everything is fine when using Chrome, but we prefer Firefox. Is this a conflict in the new Apple OS? Is there a fix?

For some reason after I restarted my laptop (firefox was opened) Mozilla was reset. I was logout from my acc and also firefox isn't my default browser (I didnt anything with it). Btw if I tried to open any link system will open it via firefox. But firefox still said that its not default browser in system. And if I open default apps in Windows I have 2 firefox there (and both recommend me to set is as default). Except FF I have only edge that also said that I can set is as default. After I login in my acc in firefox I haven't anything. No history, no passwords, extensions etc. What I can do here? I tried to use sync but as result I still have nothing.

Never cough smth like this before in same cases.

Reposting until I get help from someone. Windows/desktop. On Google Chrome, any streaming website I used with autoplay enabled would KEEP full screen mode ON after changing episodes. It would automatically go to a new page with the following episode and remain full screen. Why doesn't Firefox have this feature?? I'm seriously considering going back to Google Chrome for this one small feature. Every time I had any streaming service playing with autoplay enabled, I didn't have to manually select the full screen option every time. I am having to stand up and manually click full screen function. Every. Single. Time. Somebody please help me if there's a way to active that function.

For some strange reason, I get this response when logging in to local newspaper on Firefox..image one. When loading the same newspaper on Edge, I see this instead...image two. I've been in contact with the newspaper but the techs there can't figure what's happening. Is there a setting I have wrong on Firefox? Thanks for your time.

After the last Firefox update (146.0), my bookmarks bar only shows thumbnail images. The descriptive text which was previously black text on white back ground now appears to be white text on white background. (Whether my system is set to light theme or dark theme.) This happens on all of my Windows computers (both 10 and 11). How do I resolve this problem?
