I have a Mac and use Thunderbird for email. I am getting an error message as follows: Error - ... on Local Folders There is not enough disk space to download new messages. Try deleting old mail, emptying the Trash folder am comparing your mail folders and then try again.

This occurs only for a select group of folders. The info that was in the folders appears to be gone. I have deleted old mail, cleaned up the trash, etc.

It is odd because the majority of my folders don't appear to be affected. Any suggestions???

Your system has run out of application memory

On a MacBook Air with MacOS Monterey 12.1, I use Firefox 96.0.2 and Thunderbird 91.5.0. I bought this MacBook in October 2021, with 16 GB of unified RAM and 1 TB of main memory, of which 380 GB are available. Annoyingly, I get the message "Your system has run out of application memory." regularly, seriously interrupting my work, because I have to force quit Firefox and/or Thunderbird. This even happens about a day after restart.

In a typical instance, memory usage is: DeepL 67.7 MB Firefox 2.03 GB Preview 334.1 MB Thunderbird 907.4 MB Finder 75.0 MB

The answers I see on Mozilla Support do not solve my problem. In ~/Library/Application\ Support/Firefox/Profiles/aurrzm6j.default and in ~/Library/Caches/Firefox/Profiles/aurrzm6j.default, I see nothing whose name relates to Firefox.

After many and long telephone sessions with Apple Support, they conclude that my hardware, in particular the RAM module, is perfectly fine and the problem lies with lacking adaptation of the Mozilla software to the system I use.

My questions to Mozilla: Is this a known problem? Does it occur with other users as well? What is Mozilla's stand on Apple's assessment?

The article explaining a particular add-on seems to say a Firefox add-on will chose what file to put a new bookmark in, and/or rearrange bookmarks. This seems to say that rather than allowing you to make a choice. It will even rearrange the current folders or content. Am I misinterpreting? Thanks!

I recently updated to the 2021 MacBook Pro with the notch. In full screen mode earlier, firefox lowers the tab bar when the menu bar was made visible. In the newer notch models, themenu bas resides besides the notch, so a blank abr appears in place of it. I have tried messing in the config page but coulnt fix it. Any help?

Firefox & Chrome Do Not Open Website Horizontally but Dropdown or Vertically

I have Firefox Browser 96.0.2 (64-bit) and Google Chrome Version 97.0.4692.99 (Official Build) (x86_64). installed in my MacBook Pro early 2013 macOS Catalina Version 10.… (read more)

I have Firefox Browser 96.0.2 (64-bit) and Google Chrome Version 97.0.4692.99 (Official Build) (x86_64). installed in my MacBook Pro early 2013 macOS Catalina Version 10.15.7. And I've got this error message, "Warning! Internet Explorer should not be used for proper operation of the Administrator Backend" when I opened my website, ulattime.com/ulattime/administrator," which opens vertically or downward or dropdown, instead of "horizontally" and I don't have "Internet Explorer" browser. Please see screenshot, https://imgur.com/zNMVSSf. I used FireFox and Chrome either as default and had now removed it as default as the same error message happened when I used these browsers. I went to “Network Setting” of Firefox and tried “Manual proxy configuration” and I also enabled “DNS over HTTPS” and “Use Provider” “Cloudfare”(Default) and “NextDNS” and “Custom” but nothing happened. But in Safari, my website opens "horizontally" so I am keeping Safari as my default browser for now. If Firefox or Chrome opens "horizontally," I can restore either of them as my default browser again. Thank you.

In my settings I have enabled that FF asks me where to save files whenever I click on a download or choose 'save as'. This works... until it doesn't. For no reason and at random times Firefox stops asking me where I want to save downloads. It also doesn't download them automatically. It basically ignores any commands to 'save as' or download files like PDFs. The only thing that fixes the problem is restarting FF.

I'm on the latest macOS with the latest FF version, but this has also occurred on previous versions of FF.

Any suggestions?

I have a new installation of Firefox on a new M1 MacBook Pro. I copied over carefully selected settings files from my old computer, and now several icons are missing from the drop-down search and address boxes. I attempted renaming several of my transferred files to see if Firefox would rebuild them and correct the problem without success. Reinstalling Firefox was likewise unsuccessful. Does anyone know how to restore them? Please see attached image. Thank you.
