Firefox Support Forum

Firefox only offers seven filetypes for handling (open or save the file). How can I enter more, for example what to do with an xlsx file? I want Excel to open the file, not download it.

I have a fresh install of firefox on a fresh install of windows 11. I am trying to login to my dropbox account and when I get to the MFA page the "Continue" button does nothing.

There are no add-ins installed in firefox and I tried it in safe mode as well. I turned off enhanced tracking protection. The site works fine in firefox on another machine. It works in other browsers on the same machine.

Dropbox support seems to be unwilling to help, they just told me to use a different browser.

We use a firewall that doesn't support the ZSTD standard yet so I need the ability to turn it off on the Firefox browser. I haven't figured out how to do that yet since the new version came out with support for it this week. (We have turned it off for Chrome based browsers already.) It tends to break a few of hte websites we are using.

Thanks.

Since last "update" of Firefox for Windows v126.0

I can no longer access Gmail

keep getting this Error code: PR_END_OF_FILE_ERROR

can access my Gmail account on my phone using Firefox for iOS but not the laptop, what changed with the Firefox 126 update? what am I missing?

I found a file that has an IP address at the top of it. And the IP address is from China. recently my email address showed up on dark web. Do you think It could be connected. and is hack?

Almost consistently every day and often multiple times a day, Firefox will freeze up, unable to load new tabs, and sometimes will display a message that the browser has updated and requires a restart. Upon restart (when fozen), I'm prompted to create a new profile because I'm using an 'older version of Firefox'. After creating a new profile, I'm able to update the browser and switch back to my original profile.

Although this is a relatively easy fix, Firefox requiring me to restart my browser without being able to do anything else is disruptive alone, but not even completing the auto updates, crashing, and requiring me to do a workaround just to keep using the browser is driving me back to a more stable browser.

I don't remember updates requiring a restart before, or maybe they didn't happen enough to cause issues in my workflow.

I have tried using the 'restore' feature in the uninstaller hoping that it might resolve the issue with no results, but I haven't found any reasonable other options with my searches online.

I'm running Windows 10, Firefox Release 126. I had the same issue with the previous version of Firefox. I was hoping 126, would fix the Chase Bank issue.. But it did not I read several articles from FF users, I checked my User Agent Settings, they are correct. Called Chase, they said use Chrome as Firefox does not have the 'needed code' to work with Firefox. Been using Firefox with Chase for at least 5 years.

Please help, Thank you

Hi,

example given:

<a alt="bla" onclick="return gtag_report_conversion('mailto:chief@example.com?subject=bla%20bla%20bla&body=more%20bla%20bla');" href="mailto:chief@example.com?subject=bla%20bla%20bla&body=more%20bla%20bla"></a>

works well with Chrome, Edge, Samsung but NOT with Firefox. Without the onclick-Event it works with Firefox too

<a alt="bla" href="mailto:chief@example.com?subject=bla%20bla%20bla&body=more%20bla%20bla"></a>

As the onclick is essential I wonder if there is a fix for the fox?

Thanks in advance, Alex

Hello Support, when I create an email in my primary email account (karl.volger@gmail.com) and sent it out, it also shows as sent out in a different gmail account. Any reply is being sent back to me is not going into my primary account, but to the other account, my email is shown being sent from there, and not from my primary account. All the settings in my primary account are shown the correct settings for sending and receiving emails. The only thing I did notice that I have dual folders in the primary account of Drafts and Sent..... Please see the attached image.

Thank you and best regards, Karl Volger

It takes a lot longer than it should to load my home page, MSN. This problem is more pronounced with Firefox than other browsers. What can be done to load the home page faster? And, in general to load websites? Can someone help? Thank you.

I couldn't sign in to my Ring App and received Incompatible Browser error message. Ring Support told me the new version of their app, which uses my default browser to log only works with Chrome or Samsung Browsers (I've never heard of Samsung Browser). Furthermore, they said I had to delete Firefox from my mobile device in order to get Ring App to work.

This seems ridiculous. What's the problem here please??

I prefer to use Firefox, why do I have so many compatibility issues?

AVG has ended Online Security Add on for Firefox and AVG has told me that I may not be secure when I use Firefox. How can I stay secure on Firefox. I do not want to have to use any other browser.

Hello there, for past few days I'm having issues mainly on Twitch.tv - the streams do work fine, but whole website is displayed as text - Avatars, emotes, badges are displaying as text, or don't display at all, I'm attaching screenshots as examples. What I've tried - restarting PC, router, full re-install of Firefox, disabling all add-ons and uinstalling them (7tv and FFZ), private mode, troubleshooting mode, creating a new profile in Firefox, checked firewall settings, checked AV settings and did multiple scans - nothing was found, tried changing Firefox security Settings, also cleared cache and cookies.

I think that's everything - I was doing everything that was in the article: https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems

Regarding other websites - this is completely random, mail works, some websites also do, but on some it gets stuck, like for example when I have to do a 2FA somewhere and get a pop-up window to click "login" or type a code, it just gets stuck and nothing shows up.

Not sure if this helps, but exactly same issues appear on different browsers - Chrome, Edge, but only on PC. I tried Firefox on mobile and it worked just fine.

If I can provide more details please let me know, I did attach the "Troubleshooting Information" so hopefully this also helps.

Thank you in advance!
