Firefox Support Forum

Hello,

When I go to update Firefox through the settings > general > firefox updates > check for updates, I am getting the error in the title. I can manually download the app installer and update to the most current version which is what I did for version 125.0.1, yesterday.

I have tried uninstalling and reinstalling firefox, installing the beta branch, refreshing firefox, running in troubleshooting mode, completely deleting all user firefox files, and I still get the error. No DNS resolver issues to the update server. No firewall issues. No network blocking (tested with other devices).

This issue started after March update to 124.0.1 and continues to current stable release 125.0.1.

This issue also seems to extend to checking for extension updates.

Below are browser logs for when i try to check for update or update extensions.

I accidentally pressed a lot of keys on my keyboard and for some reason the default colors of Firefox have changed. I found out that by using Ctrl+Alt+D that I can switch the colors back to normal or to the colors that now appear automatically, but this only works for one tab. If I open a new tab, it shows the weird colors (see images below). I tried looking up specific shortcuts for Firefox considering the shortcut mentioned before (Ctrl+Alt+D) only works on Firefox. But I can't find any shortcut tied to that combination. I'm unsure what to do and how to fix this.

I would appreciate it if someone could tell me how to fix this.

This link does not fully load using Firefox, but does using Chrome.

https://act.environmentaldefence.ca/page/147607/petition/1

I am unable to sign the petition because the whole form does not show up in Firefox.

I use a web application that lists items in a table, which provides a link to download the table as a CSV file. It used to work fine in previous versions of Firefox. However, in the current version, while the file save dialog defaults to a filename that ends in .csv and CSV is selected in the "Save as type:" drop-down, the data in the file that Firefox actually saves is in XML rather than CSV format. I don't know in which version of Firefox this behavior changed, as it's been a couple years since I tried to use this feature. Or I suppose it actually could be a new bug. I do know that when I use the same feature in Microsoft Edge, it saves the CSV file in the correct format, so this behavior seems to be peculiar to Firefox, rather than anything wrong with the web application.

I have a unique annoyance wherein I use a considerably long email address for many sites. I've gotten tired of typing it out whenever it comes up and wish for it to be preserved as an autofill across all sites so I no longer have to, similar to how your phone may suggest your email address in autocomplete.

Unfortunately, as far as I can tell, you can only manually add autofills for specific sites and with password attached. So my question is, is there a way to make the address be a suggested autofill on username/email address boxes across all sites?

(not interested in having form history saved, just want this one specific form entry)

Hi,

I have Windows OS and use Firefox as my main browser. Firefox settings are set for dark mode and it works in google.com etc, but when I open iCloud Notes, it's full white and not in dark mode. Can someone advise how to change iCloud Notes also to dark mode? I have cleared cache etc, not helping.

Netflix all of a sudden wont work on firefox after update. still works on edge and my computer in other room which has an update firefox popup that i have not done yet. i reset drm already. it wont even sign in through firefox. i was on the phone with netflix for an hour they said use chrome which i hate or edge which is equally horrible but both work just not firefox. f7111-1957-205002 this code popped once. never had this kind of problem before. i already cleared cash and redownloaded firefox and all that jazz.

Hi,

I'm using FF on Fedora 39.

However Firefox does not remember any file associations. The MimeTypes.rdf file in the profile is missing and is also not created on restarting the browser.

In the options I've now set the configuration to "Ask whether to open or save files". Now I see a popup when clicking on a file however there is no checkbox with "remember this file associations" (or something similiar).

Hi

I've been having an issue logging into Gmail using Firefox. I've used both Gmail and Firefox for years and have never had a problem, but I now get stuck in an endless loop on the Gmail login page. I select my account, enter my password, then get sent back to the account selection page.

The problem seems to be relating to me trying to link two Gmail addresses so that mail from one is forwarded to the other. I set up one account this way without any issue, but when I went to do it with a different account, I got an error code. After that, I was logged out of Gmail in Firefox and haven't been able to log back in.

Things I've tried so far:

• Using a different browser. I can log in without issues in Chrome.
• Logging in with a different method. Neither my password nor my passkey work.
• Logging in with a different Gmail account. All of my accounts seem to be stuck in this way.
• Disabling all my extensions. This doesn't help.
• Clearing Firefox's cache. No luck here.
• Restarting Firefox and restarting my PC. Turning it off and on again doesn't fix it.
• Contacting Google support. They said they think it's a browser issue as I don't have any problems using Chrome.
• Using Firefox's private browsing mode. This does work and I can log in to Gmail. However, I don't know exactly what the problem is because I've disabled all my extensions and cleared the cache in regular browsing mode and still can't log in that way.

So I have a partial solution (using Firefox's private browsing mode) but it's not a long-term fix. What else can I try? Has anyone else seen this problem before and been able to fix it?

Many, many websites now have this behavior: at the top of an article or blog post is an embedded video. (Or sometimes, partway through.) Scrolling past the video causes it to jump to a sticky position in the lower right corner of the window. (See attached screenshot.) Also, even if various disable-autoplay boxes are ticked in my settings, the shifted video will always start playing.

Granted, most sites provide a little "X" to close the video. At worst, there is the pause option. But still, it's an annoyance to have to do this on soooo many sites, every time I visit to read something.

Key word there: read.

My point is: if I wanted to watch the video, I would have, when it was right there in front of me. Since I have scrolled past it, this ought to be an indication that I do not want to watch the video.

So, the request is some sort of option in Settings that would prevent this behavior. Enabling it would do nothing else to the page except prevent the behavior as described.

Thanks for listening!

Hello,

I run a WP elearning site (cd-dojo.com) and I prefer to use Firefox for everything.

Recently I added a plugin and experienced an error and WP went into recovery mode - displaying a message and an exit recovery mode button.

I have since resolved the error, but was perplexed because I could click the exit button but the messaging was persistent. I did everything I could think of - including the recommendations of tech support - until I was ready to reinstall a backup. Then I thought maybe it's a browser issue, so I logged in as admin in Safari and the message is gone. See screenshots below.

Since then I have tried everything I can to remedy with your support information including restarting the computer, clearing the cookies and cache, restarting in troubleshoot mode, and reinstalling firefox. Nothing has resulted in any resolution.

So, I'm presenting this to you. I can continue to work on the site using other browsers but I prefer to use Firefox. Can you help?

I have language set to English (GB) but am being constantly annoyed with words like "colour" being underlined as badly spelt. Why aren't you using an English (GB) dictionary?

I made a small CSS customization to my tabs in FF 115 ESR on Windows 7, so they would be flat on the bottom and rounded on the top, looking a bit more like tabs instead of buttons.

Looked ok in FF 115 ESR.

However, in FF 125, half the tabs are now cut off, including their text (see attached images).

Also the tabs background is darker in FF 115 ESR, providing more contrast between the tabs and the tab bar. In FF 125, it's almost all white and I can hardly distinguish between the tabs and the tab bar.

Why is there such a big difference in appearance between FF 115 ESR on Windows 7, and FF 125 on Windows 10?

Here is the code I used...

/* ------------------ RESIZE TAB BAR ----------------------------- */ \#TabsToolbar { height: 27px !important; margin-top: -1px !important; margin-bottom: 0px !important; } \#tabbrowser-tabs { height:25px!important; min-height:25px!important; }

.tab-background-start[selected=true]::after, .tab-background-start[selected=true]::before, .tab-background-start, .tab-background-end, .tab-background-end[selected=true]::after, .tab-background-end[selected=true]::before {

 min-height:25px!important;

.tabbrowser-tab {
 max-height: 25px !important;
 border-color: #8f939e;

 max-height: 25px !important;
 border-color: #8f939e;

} /* ------------------ TAB HEIGHT END ----------------------------- */

I inserted backslashes at the beginning of the first 2 lines of code above to preserve the hashtag sign (otherwise it displays an index number before those lines), please ignore the backslashes.

I would like my customizations in Firefox 125 to look like the ones I made in 115 ESR.

Is it possible?

Thanks!
