Every now and then Firefox asks to to shut down the program and reopen it. But when I do that I lose all the open tabs I had before. I also tried the new container tab system but it doesn't work

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?

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.

Firefox crashed and I cannot recover my tabs from history. I click on restore all tabs and it does nothing. The tabs I was hoping to recover do not even appear in my history either.

Myself and a colleague who both use Firefox on Mac are experiencing the exact same issues.

1. Table header cells don't show their text, unless we specify a font for the table

I tried to put an example of the HTML here but it was rendered as a table by this page. I'll add some images of the code instead to show it.

In Firefox the Header cells are not visible, but in Chrome the text appears correctly.

If we add CSS like...

<style> table { font-family: Arial, Helvetica, sans-serif; } </style>

...in the header then the missing text in the THs appears.

2. Other font issues

The Wave accessibility extension has text that doesn't appear and throw errors like this in the console...

downloadable font: rejected by sanitizer (font-family: "Open Sans" style:normal weight:400 stretch:100 src index:3) source: moz-extension://b86260c9-33f6-4529-b12f-a101d8607bd4/styles/open-sans-v17-latin-regular.woff

These only occur on Firefox on our Macs. Fine on PC and other browsers on the Macs.

We tried a whole series of tweaks to settings to try fix this.

I have tried resetting Firefox and doing a fresh install but nothing fixes either issue. Are these known issues with recent Firefox releases on Mac?

I am trying to set up a new computer. I have customized the homepage and new windows to a preferred page, however I cannot customize the new tab settings. The only options for a new tab are either Firefox homepage or blank page. I am trying to find a way to have my preferred homepage open when I open a new tab.

HI,

I updated recently the Firefox installation on my Mac to 139.0.1. I noticed that I can no longer print from certain websites using Firefox. One example is from Alaskair, where I tried to print a ticket and it was just sitting there trying. I had no problem printing the same with Safari.

Is this a known problem? Any suggestion (other than just give up on Firefox and use Safari) for what to do about this?

Every time I update Firefox, new bugs cause annoying problems. That's why I usually not updating for a long time.

Thanks.

All of a sudden, I can't access several websites through Firefox that I have used for years -- but I CAN access them in other browsers, like Chrome and Safari. Also, Firefox no longer works with my password manager. Until about two weeks ago, I could always autofill login information, but no more.

What gives? I am up to date on my IOS (Sequoia 15.5) and on my version of firefox -- and my password manager app. Superfrustrating. I hate to have to turn to Chrome as my primary browser since I hate Google, but I might end up doing that and just not using Firefox anymore, after like 20 years of having it as my primary browser.

I just bought my boyfriend a new iMac. We are having trouble loading many sites and platforms using the latest Firefox browser. The list is growing but includes Facebook, Meetup, Wikipedia, chess.com, nytimes.com - in all cases, rather than a login screen, we get an error message or a home page loads with no access to other pages or login area. I've cleared the cache, restarted, tried going directly to the site to log in, but nothing works. Everything is fine when using Chrome, but we prefer Firefox. Is this a conflict in the new Apple OS? Is there a fix?

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.

I'm on a Mac: 115.0.2 (64-bit)

Can someone explain why my PHOTO ALBUMS are not showing up on a website where I'm attempting to upload photos from these albums from my MacBook Air? It does allow me to drag and drop, but the actual albums are not showing up when I 'BROWSE." On my iphone and ipad the individual albums are showing up when I browse in the website to upload. It's only on my MacBook Air that the albums are not showing up. All my photos are there, but not the individual albums.

Is there a way for me to opt out of any new "AI" functionality/features that would otherwise be enabled by default? Like the tab suggestions and perplexity in search. Having AI shoved down my throat from every corner of the internet is kind of frustrating.

PLEASE READ THOROUGHLY - Thru Firefox, I use Tineye to find related photos - I use it all the time, it's been great - I always use a VPN and have never had problems until now (as of yesterday). Now it won't search, a verify you're human window comes up, and I have to keep clicking squares, which I do - but then it says to allow cookies and start over. Well I don't want to allow cookies (Firefox-Mozilla kinda encourages using their tools to block cookies, which I much prefer), and I CANT FIND WHERE TO ALLOW (not yelling its just that I said this before and it wasn't noticed) cookies even if I did (I went to Firefox preferences all I could find was under privacy & security cross-site cookies but that did nothing) and I don't want to disable my VPN. Maybe I should mention that I just added or started a Mozilla account, as I have had immense trouble with my aol emails, and am trying to move everything over to a gmail account. My sign in to Firefox was the aol email, and I had to try (I thought I did it) add another account, which I think I did successfully. So it was right after that, that all this started. Help please! Thank you! I did get the following reply, saying to allow cookies (BUT I DON"T KNOW HOW OR WHERE TO DO IT) and something about a new browser profile and to stay out of my sync account, and I APOLOGIZE, but I have no clue what all that means. What is a broweser profile, what is a sync account and how do I stay out of it? I guess well I know i'm not too smart about this kinda stuff, so I apologize but I think I need detailed step by step what to do to fix this. I know thats a lot of typing, sorry.

Hello Firefox team,

I did update my Mac to IOS 26.0.1 and I have lost all the history and bookmarks, I have the "Sync" enabled with my browser.

All my important data has been lost, can you please look into this and help me please.

Thanks, Sajeel Irkal

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 been using Tor.browser as my default web browser on Macbook for months. Firefox is my 2nd, but two days ago, i was kicked out of Tor, cannot download/use it anymore and the reasons given are as follows:

"Tor.browser quit unexpectedly. Click Reopen to open the application again. Click Report to see more detailed information." Ignore Report Reopen (options)

when i have deleted and tried to re-install tor browser, I get the notification that

"Tor Browser quit unexpectedly". No matter what I do

 (I have since done both, obviously & have tried many other things, including trying to Time Travel, which I am not 100% sure how to yet).  the Report states Firefox is responsible for blocking Tor.  how did this happen and suggestions on how to fix.  I have to access Tor to find some pertinent files etc. I have stored there.  thanks

I was in a meeting and needed to show my screen. Clicked the button at bottom to share and schecked entire screen then allow....it said firefox wouldn't allow me to share because of firefox. I also tried to just share Acrobat and had same result. What setting or plugin do I need to set to allow screen sharing in Google meet, microsoft team and zoom meetings?
