Firefox コミュニティフォーラム

I keep getting '500 error' when trying to login to my Evergy account. The Evergy support was helpful so I could use Google Chrome however I would like to use my Firefox browser. They had me clear browser history, cookies and other site data and cached images and files. Then restart the Google Chrome browser. How can I get the same data cleared in Firefox?

I have used the privacy and security settings in Firefox and cleared cache and history and cookies, but still can't log into my account.

This has been an issue since 12/01/2024

Hi Ive just installed macOS Sequoia and Firefox is really slow and showing a refreshing spining icon with a few tabs open, this never happened before the update. Is there anything I can do?

How can I stop advertisers from changing my 'Settings' fields 'Home page and new windows' to their URL which brings up their page before I can enter my password? I'm on Linux Desk Top.

I did some googling first and it seems to be an on and off issue mozilla has had with years. Anyway, whenever I play a video (be it youtube, twitter, instagram, even gifs on twitter actually) the video will often mess up and become a chaotic jumbled garbled up mess of green with junk artifacts over the video. The audio will play fine. It's like watching a scrambled TV station from a 90s bootleg cablebox, but green.

This issue doesn't exist in any of my other browsers.

I'd love to continue supporting Firefox instead of Chrome, but this is a persistent issue across the entire internet, so it's kinda obvious I need to stop using Firefox until this is patched. Thanks.

M2 Mac Mini 2023 running MacOS Sequoia 15.2. Firefox will not open after upgrading to MacOS 15.2. Searching online both Mozilla and Apple recommend uninstalling Firefox by dragging the app to the Trash and reinstalling. However, the Mac won't allow me to drag Firefox to the Trash. There are no Firefox processes running in Activity Monitor and the Firewall is turned off. Also, I'm unable to start Firefox in safe mode. I deleted the Library folder in Application Support for Firefox and still can't open the app or uninstall it. If I attempt to install a new copy of Firefox over the existing app I get the error message shown in the screenshot below. Can anyone suggest how to fix this?

This is the second time I have put this forward. Using Firefox on Windows 10, I am unable to view yahoo emails. I get a white screen with a black bar across the top. Yahoo will tell me I have "5 unread messages". If I go into Yahoo using Edge, I can view the emails (which is why I think it must be a Firefox problem, but I may be mistaken. The one response was to empty the cache and such, which I have done and it doesn't help. Does Firefox not empty its cache each time I leave the site?

If this is a Firefox/Yahoo interactive problem, I apologize - it may be something about Yahoo. I have wandered all over their support sections though, without finding a potential solution.

Thanks for any support/suggestions you can make.

Hello, I have a problem with Firefox desktop windows, When I'm trying to copy a text or word for pasting in my document or even translating, it doesn't let me select any part of the text The site I'm trying to copy is mainly link.springer.com ( The link is : https://link.springer.com/article/10.1007/s00423-024-03366-0 ) and the thing is I know copying isn't banned in that site because I can easily copy it in google chrome The version is 133.0 (aarch64) and there isn't any update for this Is there any solution for this?

I am trying to use a backup of my mozilla thunderbird messages but after having exported them (automatically put in a file called Thunderbird_profile_backup) I cannot open the file and use these important informations

Hi, on certain websites, like Steam Store and IMDB (for video game or movie/tv trailers), when I play a video but then switch tabs or minimize etc. the video immediately pauses itself, on other websites however like YouTube for example, this isn't the case and the video continues to play in the background, which is how I want it to behave for the websites mentioned above as well.

So I just wanted to ask if this is a setting imposed by the website itself, like Steam, or if it comes from the browser or maybe video player software or windows side etc. and I can change it by changing some settings or something, or is this something I can't do anything about and just have to accept as it is by unbypassable design of the website?

Thanks for any help or info.
