Firefox Support Forum

Hi there,

About 4 days ago, hotmail suddenly stopped loading on Firefox (though I can still access it on Safari). I've tried clearing my cache and add-ons, etc. I've googled a ton and tried all the things I can find to try, but nothing is working. I am by no means a tech person and so I'm out of ideas and need some help. I know I can use Safari, but I really hate using it and prefer Firefox. Any ideas on what to do? I am using a MacBook Pro - Sonoma 14.4.1

Thank you so much! Jocelyn Pascall

Once updated Firefox all old tabs didn't open ( and it was not possible to restore them anymore). So I'd like to restore all old tabs of yesterday session. Really important for my work. Looking forward to hearing from you asap. Regards, Orlando.

I am afraid to update to Firefox 124 for fear of losing the existing order of 100s of open tabs if the default setting of ordering tabs by "Recently Opened" kicks in before I have a chance to change the setting to "Tab Order". Can anyone help me? I'd like to upgrade to 124 if I can do so safely!

Hello. In the last few days when I visit my Shopify website, the pricing on my products is not visible. This is only for me, nobody else has this issue. I do not have this issue on Safari, or on Firefox when I open a private browsing window. It is something to do with Firefox, but I don't want to have to open a private window every time I go to my store. Is there a solution? This has only been happening for the last few days. Thanks

After years of accessing www.youtube.com with Firefox with no problem, the website is no longer accessible as of yesterday. When I point my browser to that URL, I get a screen with greyed out video previews, greyed out titles, greyed out account access and a search window that does not do anything. I can access YouTube just fine with Safari. I've cleared my cache. Please advise.

I've tried going into Full Screen mode three different ways:

• Clicking the green MacOS button in the upper left of the window
• In the Firefox menu in the upper right, to the right of the Zoom choice I click the full screen icon
• Pressing Command+Shift+F

But whatever way I do it, I still see the tab bar, address bar, and bookmarks toolbar rather than a true full screen. Not sure what I'm doing wrong.

Hi there,

I need to be able to use Command-I (for italics) or Command-B (for bold) when using Firefox to write emails and enter information on other websites WITHOUT Firefox opening Page Information or Bookmarks.

This is basic browser functionality! People use browsers to write emails and other online documents, and the hotkey combo for things like Bold and Italics on Macs are Cmd-B and Cmd-I. All such websites I use recognize that as a standard, but Firefox insists on using those same commands for browser features I almost never use and certainly don't need hotkeys for.

All the information I'm finding online on how to fix this is deeply unhelpful and far more complicated than I can handle. Can you please tell me if there is a simple way to stop Firefox from pulling up Page Information and Bookmarks as a result of keyboard commands, or at least for me to change what those commands are so that they don't conflict with industry standard commands for text formatting on the vast majority of websites?

It has been observed that when a user uses the Firefox browser and tries to download a DDD file, the file format is .pdf instead of .ddd. In the devtools, it was observed that the content-type is text/plain in the response to the request. I changed the content-type to application/octet-stream, but the error still persists

I've got an M2 MacAir running the latest version of Sonoma. Within the last week, the battery power has fallen off a cliff. It barely runs for a couple of hours and recharging takes nearly half a day. I'm not running anything unusual just social media & YT videos. This seems to have coincided with the latest Firefox update. I was wondering if this might be contributing to it or if this is a common problem since Sonoma & FF updates?

Anyone any ideas?

Your instructions under "help" say to click on "Firefox" and click on "preferences". When I click on Firefox the menu does NOT have "Preferences" in it. What's up with that?? And how do I clear the cache and cookies?

I am trying to block myself from checking on my old employer's website, and I need to block myself from being able to go to their web page. How do I block a specific website? I do not want to access this site, and I find myself checking the site. I sound nuts, I know. But this is for my own good.

Hey there,

Starting with Firefox v115, you had to set layout.css.page-size.enabled to false in about:config to get the page orientation back for printing PDFs (i.e. Portrait or Landscape).

It seems with the release of v119, this once again is broken and the layout.css.page-size.enabled setting no longer works. Is there something else that needs to be done now? We rely heavily on this and our current workaround is installing the ESR version of Firefox but seems like it'll catch up eventually.

Any help would be greatly appreciated!

Thanks!

Hi,

I've been using firefox for 10 years and this is the first time this is happening on me. Firefox was working fine but it does not work starting yesterday, simple task like opening and starting a new tab firefox took more than 20 seconds. None of the pages are showing anything, even those about:config pages are not working Every other browsers, like safari and chrome is working perfectly.

I tried to refresh, reset, safe mode, uninstall and deleted library/caches/firefox, library/application support/firefox, but the same problem still occurs.

My specs: macos 14.1. intel 13900kf, 6800xt, corsair vengeance ddr5 48gb, wd 850x ssd

Here is what is showing in terminal. Thank you.

Is there some way to enable and disable specific config settings , on a per-site basis?

For example, let's say I want to disable right-click hijacking (dom.event.contextmenu.enabled) on turtlesaregreat.com, but use the default settings everywhere else.

The Page Info > Permissions panel has some, but not all the ones I want. Is this somehow built into Firefox, or maybe there's an extension?

Thanks.
