Issue: When Firefox starts after a system reboot, it starts on the incorrect desktop. This seems to be off by one; that is, I have Firefox assigned to Desktop 3 (using the Dock icon's Options menu). Under normal operation, it starts on Desktop 3, but after a reboot, it seems to start on (more recently) Desktop 2 or (earlier) Desktop 4. Unsure about what causes it to prefer 2 vs. 4.

This seems to happen after I've shut down (quit Firefox normally, shut down without reopening windows on login, power goes off, power on, log in, then click on the Firefox icon in the Dock) or after a system update (which reopens windows on login for me after rebooting and installing the update). It does not seem to happen after a Firefox update or after quitting Firefox normally and then restarting it from the Dock icon right away.

Pretty irritating, as I have major applications assigned to specific desktops, and Firefox is the only one that seems to forget which desktop it should be on.

Details:

Firefox 150.0.3 (aarch64):

• Settings > General > Startup > Open previous windows and tabs > TRUE (checked)

macos 26.5 (25F71) Tahoe:

• Settings > Desktop and Dock > Mission Control:
• ---> Automatically rearrange Spaces based on most recent use: FALSE
• ---> ...switch to a Space with open windows for that application: TRUE
• ---> Group windows by application: TRUE
• ---> Displays have separate Spaces: TRUE
• Dock > Firefox application icon > [Right Click] > Options > Assign To > This Desktop (i.e., Desktop 3)
• Apple Menu > Shutdown > Reopen windows when logging in: FALSE

MacBook Air M4 2025 24 GB RAM:

• No external displays connected

I have checked my setttings to ensure everything to do with history is checked and all is showing as it should but when I start typing in the URL search bar, none of my previously visited websites appear. They are still in my history so i know they haven't been cleared but it is frustrating, as even after I manually type in the address, if I try to go back to that website later the same day it still doesn't appear.

I have noai.duckduckgo.com set as my default search engine. Almost always (but not quite every time) when I type anything into the address/search bar, I get a page with a "Server Not Found" error. (See attached image.) Refreshing the page immediately brings up the results without issue, but I consistently get the error first.

Oddly, if I go into settings and switch to a different search engine and then switch back to duckduckgo, the issue will briefly resolve and it'll work fine for a short while... and then I start getting the error again.

Is there any way to fix this?

I'm having problems with AOL ad blockers. The program says that I have ad blocker plus turned on in my Firefox extensions. I turned everything off in the exension menu and still have the same issue.

bold textWhen I opened my computer this morning without warning the Firefox had a new default page and all my information was gone. I've tried deleting and redownloading and trying to follow the instructions on how to transfer the information, I could not get anything to work. I know I'm doing something wrong but have no ideas what I am suppose to do. Very disappointed I had some importat information on the desktop and would like to get it back.

Firefox has been my default browser on Mac IOS for several years. I update Firefox regularly, the last being several days ago. I've recently had problems with Firefox freezing as I sometimes manually log-in to Amazon. All other tabs are affected. I have to quit, reopen.

  It is now affecting my purchases on Amazon.  I'm asked to provide a security code from my bank to complete the purchase. The code is initially accepted, but quickly the purchase is rejected by Amazon. Both Amazon and my bank said that there were no blocks on my account.
  I subsequently went to Safari, where I have no problems whatsoever with Amazon. Amazon has not asked me for a bank code to domplete the purchase.
  I think the problem is in my Settings, but it all looks okay. Cookies are cleared. Suggestions are appreciated. Thanks

All but 2 of my previous saved windows have been lost. They are not recoverable or present when trying to use "Recently closed windows." How could this happen? More importantly, how can I recover them? They contain numerous tabs that will be impossible to recreate from memory.

Since updating to the new Firefox 150.0 (aarch64) - two of our client's websites are having issues with too big/distorted logos (png files).

Sites are A-OK in Sarfari and Chrome.

Remade the images and re-uploaded (thinking the files were corrupt). Did not fix the situation. Cleared every cache available (object, builder, browser, hosting).

Could there be an issues with the browser?

I used the UK location to access BBC Sounds but it advised that I was out of the area (UK). I note that the URL becomes https://www.bbc.com/audio (the international alternative) in stead of https://www.bbc.com/Sounds (the domestic alternative). This prevents me from accessing the radio channels that I am seeking, namely Radios 3, 4 and 4Xtra and iPlayer.

When I open a new tab, I am shown topics on news, science, culture, etc> the first topics I am shown are sensational trivial garbage. I always enjoy seeing informative and educational content, but Firefox prioritizes gossip, Hollywood personalities and advertisements disguised as news.. You also prioritize hearsay, negativity, and biased news articles. Are your editors doing this deliberately, or are they simply focused on immature minds and biases? How do I change this, or should I eliminate all content from the new tab page? Thank you.

My problem may not be from the same cause, but I'm experiencing the same issue. Ever since my MacBook M3 Max updated to Tahoe, Firefox has been draining my battery incredibly fast. Before Tahoe, I could count on 8-9 hours of constant work with mixed use of higher processing work. Now, I'm lucky to get 4 hours of light browsing. Before I totally blame Apple, has anyone else experienced a recent shift?

Bonjour, J'utilise Firefox depuis plusieurs années sur Mac et, jusqu'ici, tout fonctionnait bien. Depuis quelques mois, la navigation est ralentie voire bloquée. La roue multicolore tourne pendant quelques secondes à plusieurs minutes, allant jusquà bloquer le système et forcer le redémarrage. Pour continuer à travailler, je suis contrainte d'utiliser d'autres navigateurs, dont Chrome (!), sur lesquels je n'ai pas de problème.

Lorsque Firefox est en arrêt (roue qui tourne pendant plusieurs minutes), je peux basculer sur un autre navigateurs ou utiliser un autre programme sans difficulté. Le problème vient bien de Firefox. Aucune mise à jour iOS ou de Firefox n'est venue à bout de cette difficulté.

Je rencontre ce problème, quel que soit le type d'onglets ou programmes ouverts. Le message d'erreur me dit que j'utilise trop de mémoire pour les applications, mais les autres navigateurs fonctionnent parfaitement dans les mêmes conditions. Et ces applications sont par ailleurs nécessaires à mon activité.

Si vous pouvez m'aider, je serais ravie de pouvoir continuer à profiter de la sécurité de Firefox.

Merci à vous, Manuella Georget
