Webpages saved as PDFs using FF are very large files compared to the same webpage saved as a PDF using Safari. FF will create a 2-3 page pdf that is over 3 MB of data, while Safari saves the same pdf as 325KB. I never noticed this to be the case in the distant past but as my available storage space started shrinking rapidly on my MacBook I realized this might be the culprit.

I don't know when these large pdfs files started with FF but as I reviewed some similar files from several years ago, the same type of 2-3 page pdf in FF was in the KB, not MB of data. Can anyone help me understand why this is happening? Is there a setting that should be changed so these pdfs are not so bloated in size?

I am still using FF 88.0.1 having not made the leap to the newer versions of FF because of all the bad reviews. That said, I have not seen any info which indicates that FF scaled down pdf file sizes in the newer versions of FF.

In FF's Preferences pane PDFs are set to open in FF. Would it help reduce the file sizes if I changed that so they open in Mac's default application which I assume is Preview? I don't know if that's what the default preference was years ago when FF pdfs were much smaller files, or if changing that would make no difference at all.

Also, for what it's worth, I previously disabled FF's new-ish Print Preview Interface in about:config because it was consistently overriding the preset positions I set for my headers and footers, resulting in them being cut off the printed pages, however, the bloated pdfs were a problem long before FF introduced the Print Preview Interface feature.

Any suggestions on how to reduce the size of pdfs that FF is creating? I don't have and don't want to get a 3rd party application like Adobe Acrobat to deal with this, when I can simply use Safari as my browser. 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?

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 10.15.7. 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.

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?

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?

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!

Hi, I've updated from ff95 to 96.0.2 and found that my files on google docs have not been loading properly. The text is blurred and it gives an error saying 'some fonts could not be loaded. please reload'. This seems to only happen in firefox and is fine in chrome and as well as when I downgraged to ff95 on my old profile. Back on 96.0.2, I've tried clearing cookies and cache, safe-mode, setting theme to default, all to no avail. Are there any other ways I could troubleshoot this issue? I've attached an image that shows what the text looks like on chrome and the latest version of firefox.

Dear Sir,

I have my firefox username and password. However, whenever I try to sign in nowadays, I am asked to enter a verification code that is sent to my email address within five minutes. The email does arrive, but never withing 5 minutes. I have tried it many times on different devices. It may be my email issue. However, I cannot change the email account unless I cannot log it. Since I cannot receive the verification code within 5 minutes, I am unable to change any of my personal details.

Please advise.

Yours sincerely, Tan Ngiap Heng

P.S. It was very difficult gettting to this support page. I was asked to log in and verify before continuing for some of the support pages. But like I mentioned, I am unable to receive the verification code within 5 minutes. So I am thankful for this page.
