I used to run Firefox 88.0.1 (64 bit) on a Windows 7 PC. With lots of help from this forum I wrote a userchrome.css file to make several changes to the appearance.

On a new Windows 10 machine I installed the same version of Firefox (since I don't care for the latest one). I added my old profle to the new installation and selected it as the default.

Unfortunately, when I opened the program I was prompted to create a new profile; there didn't seem to be any way around this. So I let it happen and tried simply copying my old chrome folder into it - I thought at least I could make the visual changes even if I couldn't import my bookmarks and so on.

But this didn't work either: when I run the program, none of the expected changes are there.

Presumably I've done something wrong, but what, exactly? I'd be grateful for any thoughts. Ideally, I'd like to use the whole of the old Win7 profile but if that's not possible at least changing the appearance would be pleasant.

Many thanks.

I purchase audiobooks on Audible.com using my Mac (OS Catalina). When I download a purchase Firefox sends it as an MP4 file which is incompatible with the apps to play the audiobook. Safari and other browsers do no do this - the files come as an .aax file. Even after I have an .aax file I cannot play it using Firefox because Audible.com does not recognize my registered computer. I get an error message: Document "LicenseForCustomerToken" couldn't be opened. Incompatable with QuickTime Player. FYI: QuickTime Player is a video (MP4) player app on my computer. So, once again, Firefox makes the .aax file appear like an MP4 file to Audible. It's doing some kind of unrequested and unwanted conversion of .aax files to MP4.

I hope you can fix this in your next update. i've worked with Audible to solve this issue, but they cannot help and are telling me it is a "known issue" with Firefox and recommend I use a different browser.

Using Firefox browser for iMac. Recently (10/10/2021) attempted to download .aax files from Audible.com. Files were unexpectedly converted to .mp4 files, making files unusable by iBooks. Conferred with Audible Tech support. Audible Tech confirmed that .aax files are the proper format and that they did not/do not make any format conversions on their end. Audible Tech then suggested trying download with Safari. Download (of .aax files with Safari) was successful and maintained proper (.aax) format. Audible Tech said that he had not encountered this issue before and that it seemed to him that the Firefox browser may be responsible for the unexpected conversion. In the past I have used Firefox many times to successfully download .aax files from Audible.com, most recent prior to this problem was on (9/11/2021). I am notifying you simply to advise that you may have a programing glitch within the download programing portion of the latest version of Firefox (ver. 93.0 - 64 bit) for iMac(s).

I have just upgraded to Firefox 17 and found that Norton 360 "Login Assistant" (formally named Identity Safe) no longer works. It does not fill in the username and password fields. It worked very well and did all the right things when I was using Firefox 16. There is probably a quick fix but in the meantime I have had to revert to version 16. Looking forward to the problem being resolved.

I live in Mountain View and use Google WiFi which is provided by Google for the City of Mountain View. For the past few months, they have been having a BIG problem with the corruption of downloads. Even teensy tiny ones. Perhaps you've heard about it since you're also in Mountain View. They have not responded to repeated posts from the forum... I have an iMac running Snow Leopard 10.6.8 and I haven't been able to update my software. I go to Lane Medical Library at Stanford to use the Windows machines there. I load whatever standalone software that I can onto a jump drive and install it at home. Unfortunately, some sites (like Apple and maybe even Mozilla!) recognize the computer you're on and only allow you to download software compatible with the machine that you are actually sitting at. This means that I can't reinstall Safari because I can't get a copy of it. And it looks like I might not be able to install Firefox 17.0 either. At least, that's what I'm trying to find out. "We've made some educated guesses about your current browser and operating system." See what I mean? So when I go to the library, will I be able to download a copy of Firefox 17.0 for the Mac and install it on my computer at home? Thanks!

After updating from 16 to 17 some of the extensions that are crucial for me stopped working, got disabled and got listed as incompatible with 17.0. Now when I try to toggle the extensions.checkCompatibility.17.0 boolean into the “false” position, it readjusts itself into “true” after each restart, making it impossible to force those extensions as compatible.

Why is this happening and what can I do to make it stay at “false”?

My Macbook Pro is running 10.7.5 I got an update notice in Firefox and tried to update to v. 17.

I. When I try to move the download to the Applications folder:

(1) If I choose "Replace," I get the error message: "The operation can’t be completed because you don’t have permission to access some of the items."

(2) If I choose "Keep Both Files," I get the error message: "The operation can’t be completed because an unexpected error occurred (error code 0)."

II. Version 16 no longer works:

1. If I try to open it now, I get the error message: "You can't open the application Firefox.app because it may be damaged or incomplete."

2. If I try to throw out the damaged app, I get the error message: "The operation can’t be completed because the item “Firefox.app” is locked."

Can someone help me with this? Thanks!

A few days ago, my good old FF (12) stopped downloading and saving. Actually, in the download screen it looks as if it was downloaded (shows in its full size in the Download screen), but the 'open' option is gray and it can't be found in the download folder. Also, when using 'save as' for web pages, only the html folder (images, etc.) is found where saved, but its 'mate' (the htm file) is not, and the 'open' option (on download screen) is gray. I deleted the mimetype.rdf and the downloads.sqlite files; I disabled all the relevant FF addons, changed downloading folder etc.--- nothing helps. Do you have any idea? Thanks

Please tell me how to permanently disable FF from pinning itself to the taskbar?

Every time I launch FF and then close it, it pins itself to the taskbar. If I wanted it to be pinned there, I would have done it myself.

I haven't used Firefox in a long time, and installed it at a whim to see if there'd been any progress. Wow.

THIS IS BULLSHIT! MAKE IT STOP!

However, when I go to various sites, I keep getting the prompt that my browser is not up to date and I may not be able to view it all. when I sign in, I also get the message to update and I have done this several times with no deletion of the prompt. Should I remove FF and then reinstall it? Can you give me steps I need to take to make these prompts disappear? Thanks.
