Losing my mind on this one.

Have 2 Macs I use at home, both running FF 141.0 and Sequoia 15.5.

Use Reader for RSS and Airmail for eMail. Both have settings to allow links clicked in those programs to open browser tabs in background. Handy way of banging through newsletters and RSS feeds before shifting to browser.

One on Mac, that open in battleground setting on both apps works as it has for, oh, last several years. On the other Mac, a few days ago that open in background stopped working with Firefox. It does work properly on Chrome and Safari if I set them as default browser (and, as I mentioned above, on my other Mac).

I've tried resetting Firefox on this Mac using the troubleshooting menu and have also cleared the Firefox cache. I even tried resetting the launch database in that Mac, although the fact Chrome and Safari are working fine suggests the OS isn't the culprit.

I'm unaware of having changed any settings, but am aware that "idiot user" may be the issue.

Regardless of how this happened, any ideas how to sort this annoyance out? Thanks!

Sometimes when I go to click on songs on YouTube it doesn't show the whole bottom part of the video's screen. It has some of it but does not show the fullscreen mode option to click on. When i open up Chrome it's fine. I'm using the newest update of Firefox.

Hello,

I am trying to force two or three websites to detect my timezone as UTC, even though my local system time is not UTC. I figured out how to do this with ALL sites by setting privacy.fingerprintingProtection to "true" and entering "+JSDateTimeUTC" in privacy.fingerprintingProtection.overrides in about:config.

Now according to docs, privacy.fingerprintingProtection.granularOverrides "can be used to add or remove features on a domain granular level if privacy.fingerprintingProtection is enabled," but I can't figure out how to get it working.

Any input is appreciated.

I set up my Home Page with 3 rows of my own shortcuts (sponsored shortcuts are turned off). All were pinned and alphabetized. If I go a couple hours without using Firefox, about half of my shortcuts will have been replaced with others. None will be in order. Have tried setting up the Shortcuts several times, is really getting exasperating. Is there a simple fix in about:config?

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

Hello

There seems to be a new function that opens a quick search window when I press the apostrophe key. This function is active on many websites, and I am using Firefox 125.0.3 on a Macbook Air.

This new function makes it very difficult for me to practice touch typing in Firefox, and I would like to turn this function of.

Best regards Max Andersson

ALT-SHIFT-LEFT has been 'select word backwards' for years, at least on macs. And so it was on FF too. Now they suddenly decided to re-map it to 'select left tab'. There was already a key for that - CMD-ALT-LEFT. Which also works for the right, whereas ALT-SHIFT-RIGHT does nothin

Firefox claims does NOT save site/URL visit information while in Private Mode. And I thought that was true. However, I just discovered that Firefox DOES SAVE Private Mode URL/Site visits - in this specific place. I don't know how long the history will be saved - it looks like at least as long as the Window is open. I want to keep most of my open Private Tabs open - but want to Delete/Clear the ones I'm done with. I thought/understood that Private window/tab/visit info was not tracked/saved - and it's not saved in History, or Searchable. But it appears that this doesn't apply to the Recently Closed Tabs MenuItem. And there seems to be NO 'delete' or 'clear' option for this field. I can't find any reference to the subject in the Forum or Articles. The picture I've attached is NOT of the Recently Closed Tabs while in Private Browsing, but is the same MenuItem and field contents. Thanks for your interest. I'm hoping someone can help me figure out how to delete/clear this specific history.

I've seen the other support requests on this from the past. Setting " print.tab_modal.enabled = false " doesn't seem to work now (Firefox for Mac 141.0.3).

Is there any (2025) way to default to "print with system dialog" rather than having to choose the link off of FF's dialog every time? It makes printing to PDF (which is 95% of my "printing" from FF) needlessly tedious.

A couple of months ago, I suddenly lost all my saved bookmarks, plus the ones on my toolbar. Strange thing is, all the folders and sub-folders I created are still there, they're just all empty.

Can I get them back somehow? I've been collecting them for years so can't replace them all!

When I attempt to login it just spins and nothing happens. Works on Safari and Chrome.

Opening DevTools I can see an error about "CORS Missing Allow Origin" but I don't have this issue with any other browser. I have disabled/removed all my browser add-ons and the issue persists. I have no problems logging in to any other site.

I upgraded from 126.0.1 to 127 today. Upon update, all my windows are gone. The only way I could access them is to revert to an older profile backup and reinstall 126.0.1.

I tried exporting my session with Tab Session Manager in 126.0.1 and reopen them in 127, but that only restores the last tab of each window (oddly). The json clearly lists 3 windows each with multiple tabs. I tried copying the sessionstore-backups folder, but no dice.

On certain websites I am getting scrambled text, mostly in headings and titles, not so much in body text. I have followed several tips from other posts like mine, i.e., installed Open Sans font, but that did not do it. I turned off hardware acceleration, and cleared the cache. The only thing that did work was to start Firefox in troubleshooting mode. I only have two add-ons running, Short URL and Dashlane, I doubt they're responsible for this. Any other ideas?

I have a Plesk (apache) server that is behind HAProxy. When I connect securely to a web site through HAProxy using Firefox, I get long delays. If I use Safari or Chrome, the pages come right up without any delay.

If I connect to the Plesk server directly without HAProxy in the middle, there are no delays.

I do not know what would cause these delays that don't occur with other browsers.

Hi. The annual NORAD Santa Tracker website does not function properly under Firefox. While there are no issues with the 3D rendering itself, the 3D map is squished vertically toward the left side of the page. It appears to be defaulting to a mobile browser view. The only extension I have installed is uBlock Origin, and I turned it off for the NORAD Santa website, and the display issue persists.

Opening the site under Safari shows the Santa tracker taking up the entire browser window as it should do.

I'm currently on Mac OS Sonoma using the latest version of Firefox 121.0

Not sure if this is the correct topic selection but nothing offered above really fits.

I tried to sign into my Allstate.com account today and kept getting error messages.

I called their tech department and they told me that Firefox has been notified a long time ago about this issue but has done nothing about it. I was told to use my email account instead of my user ID to get into my account via Firefox, but that if I do it that way, some functions still won't work on Firefox.

I was told that my Safari browser would work, and it does.

Not sure why Firefox refuses to fix this. This is crazy. I've also had problems signing in some other companies with Firefox recently where it used to work fine. It looks like they are just not keeping up with technology. I have the latest Firefox browser for my Macbook, but as companies update their sites, Firefox is staying behind. I prefer Firefox because of things like uBlock Origin, Enhancer for YouTube, and YouTube Watchmarker which I love, but I've had to use Safari more and more because of this issue.

Exactly how does one let Firefox tech know these things. They don't provide anyway to contact them which doesn't look good.

I was having an odd issue the other day, that I now solved by comparing the settings on a working Firefox profile with mine.

For some reason, on one of my multiple Firefox profiles a list of web apps wasn't working. Among them were Discord, Miro Board, and Google Pay. I was suspecting that they all had the same issue, but didn't know what it was at that time.

The security settings were the obvious suspect (Ad-blockers, DNS, HTTPS enforcement etc.) because clearly something was being blocked, however nothing helped. The solution was in the Network settings. (See screenshot) I was using Manual proxy settings from the time I messed with I2P networks (or something similar).

I am not sure why having a proxy to localhost (127.0.0.1) on HTTP would somehow cause very specific major apps to stop working, while others keep working fine, but it happened to me anyway.

For anyone in a similar situation, with those particular apps not working, check your proxy settings.
