Firefox Community Forum

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).

I've set up a second profile to keep my personal and work browsing separate. When I reopen my non-default profile, it doesn't restore the previous session's tabs. I have "open previous windows and tabs" checked under Settings > General > startup in both profiles. Please advise.

I tried to use a ftp link setting firefox as the default ftp app, not realizing firefox no longer supports ftp. I am unable to reset the default app and can't find the setting to do so. I downloaded filezilla and wish to set it to be the default app for ftp. Can someone help me with this? Before anyone suggests it, resetting firefox to default settings is not an option.

I haven't upgraded browser versions for a while and I'm now going from 109 to 132. Pretty bad I know.

I'm having a number of issues but for this post I'd like to concentrate on userChrome.css.

In version 109, I had a custom font for the top menu bar, the top menus, the bookmark toolbar, the bookmark toolbar menus, and the right click menus. I did this by including the following in userChrome.css (as per [https://support.mozilla.org/si/questi.../1335097|here]:

1. navigator-toolbox { font-family:"MyFont" !important }

This worked great, but it is no longer working in version 132. Obviously I don't know in which Firefox version this stopped working.

Has this been disabled by Mozilla or has it been changed? If it's been changed, how can I achieve it now?

I'm very grateful for any help!

Hi all,

I'm using Firefox 125.0 (64-bit) on Fedora and for file downloads, I have the options "Ask whether to open or save files" and "Always ask you where to save files" enabled.

This basically works, Firefox opens a file selection dialog and I can select where I want to save my downloads - so far, so good.

The weird thing is, the default location that is shown in this dialog seems to change every time I download a file. I would expect to see the last download location as the default option, but that is not what happens.

When I check about:config, I can see the last used download path is saved as browser.download.lastDir perfectly fine, but it is not set as the default for the next download.

Is there a parameter I can set so this last path is used again?

Thanks,

M.

I have:

125.0 (64-bit) Mozilla Firefox for Ubuntu canonical - 1.0

Video on Facebook plays without sound. The video plays, I see the image normally, but no sound. Video on Youtube works perfectly.

Fresh install without addons or plugins. Switching to "Troubleshoot mode" does not change anything. Youtube with sound, Facebook without sound.

Any ideas where to look?

PLEASE READ THOROUGHLY - Thru Firefox, I use Tineye to find related photos - I use it all the time, it's been great - I always use a VPN and have never had problems until now (as of yesterday). Now it won't search, a verify you're human window comes up, and I have to keep clicking squares, which I do - but then it says to allow cookies and start over. Well I don't want to allow cookies (Firefox-Mozilla kinda encourages using their tools to block cookies, which I much prefer), and I CANT FIND WHERE TO ALLOW (not yelling its just that I said this before and it wasn't noticed) cookies even if I did (I went to Firefox preferences all I could find was under privacy & security cross-site cookies but that did nothing) and I don't want to disable my VPN. Maybe I should mention that I just added or started a Mozilla account, as I have had immense trouble with my aol emails, and am trying to move everything over to a gmail account. My sign in to Firefox was the aol email, and I had to try (I thought I did it) add another account, which I think I did successfully. So it was right after that, that all this started. Help please! Thank you! I did get the following reply, saying to allow cookies (BUT I DON"T KNOW HOW OR WHERE TO DO IT) and something about a new browser profile and to stay out of my sync account, and I APOLOGIZE, but I have no clue what all that means. What is a broweser profile, what is a sync account and how do I stay out of it? I guess well I know i'm not too smart about this kinda stuff, so I apologize but I think I need detailed step by step what to do to fix this. I know thats a lot of typing, sorry.

every time I enter some words for a search the system blocks access with an "I'm Not A Robot" process. while I always get past this it is annoying and has only started happening in the last few days.

Hello👋 I am using firefox developers edition on build 132.0b2 and my UI is not rendering correctly, the themes work but the objects like the bookmarks toolbar and the refresh button and the home button even some of my extensions is not loading and other things also not loading, but fortunately I know the keyboard shortcuts for these functions and they are working just fine but all the buttons are just not there My device is a Dell Latitude E7450 and it has a normal core I5 5300U so it is not an x86 arm based processor I hope that you find a solution ASAP as I am really struggling with my browser like this and btw I really love your work and the products that you give Thanks for doing the hard work! bye

Web pages that are supposed to contain emojis are blank. I can highlight where emojis are supposed to be shown but the actual images of the emojis aren't there. about:config font.name-list.emoji correctly contains "Apple Color Emoji" If it is relevant, this has been a bug/issue that has persisted for a couple of months now (can't name an exact date).

I have a firefox account that I use for work, which was created with my personal email address - "email"@"personalDomain".co.uk. When I try to log in using it I get a message saying that "personalDomain.co.uk" is not a valid email address. How can I log into my account which was created using this email address? The email address is valid and active, and I do have access to it.

My wife's Firefox was triggered from an e-mail link and in the process got updated to release 141.0 The result is that the tabs from the previous verion have not loaded. Can I still recover them?

Dear Mozilla Geeks—

As practically every other Firefox user, my bookmarks evolved into a lengthy file system that uses folders to segregate categories of bookmarks.

That is, it used to have this feature.

After the last update all or most of the bookmarks (I can't tell by scrolling down the long list) are devoid of their organizing folders. This puts a great deal of information beyond easy reach. In Mozilla Help topics one is advised to click on the library icon in the toolbar ... only there is no such icon on my copy of Developer's Edition.

Can someone suggest a method or methods to recover the folders?

Some passwords have been lost as well.

Yours Sincerely,

Glen

In May 2025 all browsers should have removed the default styling for the h1 element when it is nested in a sectioning element (article, aside, nav, section). I went into Firefox Dev Editions user-agent style sheet and noticed that the styling for nested h1 elements is still the same. I'm wondering why that is the case, since I was under the impression that all the major browsers had completed make the necessary adjustments at the end of May 2025.

I am using latest firefox developer edition. After firefox updated automatically, I found that I lost toolbar customization settings. I reconfigured everything, but the next day when it updates I lost the settings again. It seems that there is a bug in Firefox. How can I fix this? If this is a bug, when will it be fixed?

Over the last five hours, I have gotten 27 emails from Firefox Monitor for this data breach, for the same email address. I have already marked the breach as resolved in Monitor but I keep getting emails. Is there anything I can do about it?

Is there any addon or feature within addons management icon (from toolbar) to Disable Extensions and Apps in one-click like Chrome has via this addon?
