Firefox can not be installed on Macbook Air with M1 and Big Sure, installation can onely be done temporarily. Each time, i want to start Firefox i have to install it again. Is ther any solution? Thank you.

So Im trying to download a 1.19GB file and get 300mb/s ethernet speed using speedtest.net/ Now normally from my experience its never taken longer that 10 sec to Download such a file. Although since today, either Firefox or my pc has decided to limit download speed to 90kb/s which means this is going to take 3h or so to download. I use Windows 10, don't have a metered plan enabled or any other wifi/ethernet speed limiting things, and no third party security software. Anyone have any ideas why this could be happening? Many thanks in advance

I have been trying to install Firefox on a Windows computer running Windows 10 Pro. I have two users on the computer. I have installed Firefox successfully on the main user but every time I try to install for the second user, it does not install. it says it failed and leaves a strange icon on the desktop which, when I click, it deletes the file. I am not sure why. I have installed the same on 11 other computers with two users and no problem with those ones.

I have the download setting to "Always ask you where to save files". Unfortunately, Firefox keeps changing the setting back to the default. I understand that, unfortunately, whenever Firefox does an update it changes all my settings back to the defaults (but that's a different issue).

I have 'Firefox updates' set to only install when I okay the install. Unfortunately something is changing even when I have not run an update.

Why might my download settings be reverting back to the default setting?

I often view pictures on https://www.pixiv.net/ When I select one jpg image on pixiv.net, copy this picture and then paste it to somewhere else, It becomes completely blank. And the copied image file is broken due to unknown reasons. Here I added one picture. It shows the result when I paste a said jpg image from pixiv.net to somewhere else (like a word document page). This issue happens with firefox 83 and firefox beta 84. It never happens with firefox 82. I don't know what caused this issue.

Every time I want to download i get offidocs that wants to open the document. How to remove offidocs ? I do NOT WANT IT !!! I have libreoffice what is doing a fine job, I do not want a browser with applications on a server. SECURITY. VUNERABLE. SLOW. And I do not want an complicated way to save a text.

I have downloaded the latest browser today. I can access my Yahoo Mail, but I cannot delete or send any mail from it when using this browser. My Yahoo Mail is now useless when using Firefox. Please advise me of the solution to the problem as soon as you can.

On my MacBook pro running macOS Catalina 10.15.7 (most recent version) Firefox crashed after an update around one hour ago. I've uninstalled Firefox in the end and downloaded a new one from the site. I get 'error code - 36' over and over, see attached screen shot. I've downloaded Firefox on various different browsers, bat always this same error code. Always enjoyed Firefox without any hiccup up to now! Suggestions anyone? Thanks. Chris

Is there a way to permanently disable checking for updates? I don't want to update (and I don't care what people think about that), but every 5 minutes an update notification pops up that needs to be closed, and it is getting really annoying. Again i don't want to update and there is no option to disable checking for updates, only to automatically update whenever firefox wants to ruin my day or to bother me until I allow them to ruin it.

Hello!

I'm getting an error message from Firefox whenever I try to open it that my profile is missing or cannot be accessed (see attached image).

I have tried everything from the help articles so far, and nothing worked. I deleted the profiles.ini file, I deleted the entire Firefox folder under Application Support, I have deleted Firefox and reinstalled it. None of that worked.

Even when I try to create/delete/save my profile over the Terminal, I get the attached error message.

I love using Firefox, but I simply cannot use it this way. No matter if I use the default, developers or nightly version.

If anyone has an idea how I could fix the issue I would be incredibly thankful.

Thank you already in advance for your help!
