Firefox Community Forum

Social Security just stopped me from downloading my 2026 COLA on Firefox with an error 400 (bad request), but I was able to do it on Edge. More and more websites, particularly financial and government websites, work with Edge but not Firefox. And when I call their customer services, their first response is "try another browser!" Why do they hate Firefox?

If someone wants me to walk them through an example of the problem(s), I can do that when I pull statements or pay bills on those websites. The worst example is Synchrony Bank, which runs several credit cards I use. You may contact me by email at [email removed]@att.net (put FIREFOX PROBLEM in the title so I don't miss it).

I also have Mozilla VPN, and some things only work when I turn off the VPN, so that may be compounding the incompatibility. Although I am in Eugene (OR), the closest location for my VPN is Seattle.

Hi!  :)

Recently on bootup MS EDGE loads instead of my beloved Firefox. I did not install EDGE as I really dislike it! I know how to close it and again make Firefox my default browser, but can't I make EDGE stop loading in the first place? I have to reset Firefox as my default browser every day! Dell Desktop computer, Win 10 Pro (No, it doesn't qualify), 16 gigs of ram, 500 meg SSD Please tell me what else you need to know. This is kind of a little thing but it's driving me nuts! LOL

Hello Mozilla team,

I recently received an update for the latest version of your browser and installed it. However, all of my bookmarks appear to be missing. I have an HTML backup of my bookmarks stored on a USB drive, but when I attempt to import it into the updated browser, I receive a message stating that the file is not recognized as a bookmark file and cannot be uploaded. This is unusual, as I am able to import the same HTML file on other computers and browsers without any issues.

I also tried using the “Sync” function to restore my bookmarks, but this did not work either.

Could you please advise on how I can resolve this issue?

Regards, James

I don't have a way to manage payment methods - the article in Support doesn't match what I see in Settings. I was able to add a new credit card while using a website but I can't delete the old one.

I have 150+ tabs open of Firefox Android. I would like to close some of them conveniently.

I have synced my tabs and on desktop I have now 2 ways to access them.

1. On the left "Synced Tabs". This is very nice, I can filter by text and open the appropriate tab. Now I decide, I want to get rid of it. Closing on closes on Desktop, which is expected behavior.

2. Using the "Show tabs on other device" icon. This lists all my tabs, some directly, some in sub-directory "inactive". I could now click the x button next to the tab and close it. But: Having 150+ tabs open, it is very difficult to find the open tab in question. I even have to click "Show more tabs".

Basically I would like to use version 1, find a tab, right click and select "close synced tab".

Am I missing an option?

Hello, I want to get rid of the list of "recent bookmarks" - I don't want other users of my computer to see them. I've already set Firefox not to record history. Online search provided no useful information. My Firefox is always thelatest version. Hope you can help! - Raymond

I had some AI models downloaded, but noticed recently that the AI tab grouping wasn't working. I saw that the models for this were listed as being 0 bytes in size. I deleted all installed models and now can't install any as they always show as being 0 bytes.

I'm able to install the models when using a new profile. I have tried in troubleshooting mode and disabling all extensions using my profile normally but neither of these actions have worked.

I'm running Windows 11, 25H2, on ARM64, with the latest version of Firefox installed.

Hello,

I am writing to inquire about the difference in the fullscreen video transition animation style between Firefox on Windows and macOS.

Observed Difference:

• Windows: Uses a smooth fade-in/fade-out animation when entering and exiting fullscreen, which provides a polished user experience.
• macOS: The transition is present, but it lacks the distinct Windows-style fade effect and feels less smooth or different in style compared to the Windows version.

Settings Checked:

• I have confirmed that the about:config preferences full-screen-api.transition.duration.enter and full-screen-api.transition.duration.leave are both set to 200 200. These settings did not enable the identical Windows fade animation on macOS.

Core Question:

• Is there any current method (e.g., through advanced settings, flags, or extensions) for a user to apply the exact same smooth fade-in/fade-out fullscreen transition animation seen on Windows to Firefox for macOS?
• If there is no current way, is this difference due to limitations with the macOS graphical environment, or is there a plan to unify the animation style in future updates?

Moderator note: This question has been edited to fix the formatting.

One page of my online scheduling software often doesn't load all the way. It's a list of clients, not super-long. It often only loads the first 10-15 names (out of about 80). Eventually this pop-up appears: "This page is slowing down Firefox. To speed up your browser, stop this page."

I'm on a Windows 10 desktop with PLENTY of speed/memory. That's not the issue, unless Firefox isn't using the computer optimally.

I've been having tons of issues with Firefox so a few days ago I did a "Refresh." This helped, but obviously didn't fix this particular issue.

Against my better judgement I download the latest update for Firefox, now my computer is a mess. Things like the row of saved sites between the search line and the space where web address shows is gone. I can find the web sites , but I want the line back. I don't understand ANY of your directions or support pages. I am old and can't keep up with technology any more - I'm about five years behind.

If I just uninstall the latest version of firefox will that fix it? Or will it uninstall ALL of firefox. And please don't give me long involved directions or I will just give up because I don't understand.

I have the settings set to ask where to download files I'm saving to my computer. When downloading and/or printing a document, Firefox saves a copy to my desktop even after the "save to" prompt and saving the file to a specific location. How can I stop this?

Thank you in advance!

I have Google Calendar open in a Firefox tab. I want to add the tab to my Mac desktop Dock for quick access. I've tried dragging the tab to the Desktop and then dragging from Desktop to the Dock without success, and searches generally return how-tos for only Chrome or Safari. Help!

Hello! I saw this question (below) on the forum. I'm having much the same problem. Firefox is crashing nearly all my tabs, even those that had been previously loaded. I cannot use it at all. Clicking "Restore this tab" does nothing. (Firefox has crashed tabs in the past but in those times, "Restore Tab" actually worked.) I actually had to write down on paper the subject and website of each of my tabs (and I had a lot of them, so this took a long time) because when I clicked on each already-loaded tab, Firefox would crash it and I'd lose it--and then it would crash the next one in line before I even got to it.

I have been using Firefox for years and it has never given me this much trouble. I've had tabs stored on it for a long time. "Restore session" always worked if I had to restart my computer for something. It does not work now because every tab crashes with the notice: "GAH! Your tab crashed. Click 'Restore tab' to restore your session." But "restore tab" simply crashes again.

Firefox has allowed a Masterpiece Theater tab and a link to my local newspaper, Pioneer Press (I have a subscription). Others crash. Even some Firefox pages have crashed!

After writing down the info for all my tabs, and then clicking on each one so it would crash and then deleting them so that Firefox had no tabs listed, I tried restarting my computer but this did not help. I also checked Malwarebytes, my anti-virus program, and didn't see a problem there (and I've had it for two years, always using Firefox with not much problem). I think I clicked on "update Firefox" recently and it seemed to work for a while after that, but now this.

I know a little about computers as a user but I'm not very savvy about repair or about all the different commands and controls. Trying to browse through all your articles to find how to fix the problem is exhausting, time consuming and leaves me really confused because I don't really know how to do the things each article suggests. I don't have the time to read article after article and still not be able to fix the problem.

Do I actually need to delete Firefox and then reinstall it? I'd lose all my tabs (website history is still showing under "History), stored passwords and stored credit card information and all other stored information. I'd have to start over completely.

I love Firefox and don't want to switch to Google or some other browser but I might have to if this continues.

According to your instruction to the user below--please be sure to view her note--here are some of my recent crash reports. Thank you for any help you can give me. Please also tell me how to reply to you if what you suggest does not work.

FYI, I have Windows 10.

No matter what I try to read or go to, Firefox crashes repeatedly. I literally cannot use it at all. I keep getting: Gah. Your tab just crashed. We can help! Choose Restore This Tab or Restore All Crashed Tabs to reload the page/pages.

Clicking those options fixes nothing! How do I go back to the previous version, please?"
