Mon vieux Imac fonctionnait sans trop de problèmes jusquà présent ! Le 10 juillet 2025, il s’est « planté » sur l’opération suivante :

« Google Chrome -> Gmail -> Google Workspace »

tous mes messages apparaissent normalement quelques secondes puis l’écran se voile et devient inopérant avec la mention :

« cette version du navigateur n’est plus compatible. Veuillez installer un navigateur compatible »

Je n’ai pas les moyens d’acheter un autre Mac !

Hi all! Happy Firefox user for over 20 years here. Recently I've had to switch to Chrome for one of my use cases, Google Cloud Monitoring dashboards. They're evidently JS- and data-heavy, and they're often unusably slow in Firefox. I often see delays of 10s or seconds when clicking any button or link, rendering data, or doing anything else. They also seem to get slower the longer their tab is open in the browser. They're way more usable in Chrome; maybe not perfect, but drastically better.

Any thoughts?

I've used about:performance to take a profile on https://profiler.firefox.com/, and uploaded it to share.firefox.dev , and I know it claims to sanitize personal info, but I'm still a bit leery of posting the link publicly. Happy to share it with a Mozilla employee if that would help.

Google Meet repeatedly drops and rejoins calls with "you have lost your internet connection" error. It's been happening consistently over the past few weeks. I have zero issues if I join the same calls with Google Chrome. I've tried updating to latest, restarting Firefox, restarting my machine, but it still happens.

Over the past 2-3 months, Outlook, when opened on Firefox, continuously signs me out and forces me to sign in whenever I leave it open for more than a few minutes. Some days this occurs 5 or 6 times and has become very annoying. Even when I choose 'trust this device', or 'keep me signed in', or 'don't ask again for 30 days', it just automatically signs me out. I use 1 desktop and 1 laptop and this problem exists on both.

Also: I have a default font chosen for email composition that the system all of a sudden seemed to not recognize. I can select all content in an email and change it to my default font but it doesn't use it automatically. It either uses Segoe or Calibri depending on which computer I'm using. I have one laptop & 1 desktop. Oddly, if I place my curser down at my signature, which is formatted with my preferred font, the system will then use the correct font. As I'm typing, if I need to correct something, after doing so and trying to type the next word, it refuses to put a space between the where the curser is and the first letter of the next word. I literally have to start a new line by using the enter/return key, type the next word, then use backspace to take it back up to the previous line where it belongs. These are both small details but drive me batty!

I checked with my IT dept and they had me do a test drive on Chrome, which I NEVER use. Sadly, none of these issues exist in that browser, so for the time being I'm forced to use Chrome if I want to avoid the constant need to sign in and the other irritating malfunctions.

Anything you can point to or settings I can change to fix these issues?? Appreciate your assistance! Kayla Bates

Since a recent update, whenever I try to go to ufc.om, Firefox shows me the error in the attached image. It used to display ufc.com without issues before the update [ don't remember which update ].

Other browsers [ Chrome and Edge ] display ufc.com without issues.

I just downloaded version 140.0.4 for Mac. Now Firefox will not open any website pages. I added Firefox to the list of allowed apps in my firewall settings but that did not fix the problem. Please help. Thank you.

When I use Firefox it removes shortcuts from my home screen (starting from the right) and replaces them with sites that I visit, even if I visit them only once.

I have been to settings, Recent Activity is turned off, Rows are set to 2, and the only other option is Shortcuts > Sites you save or visit.

I don't want Firefox to automatically add visited sites to my shortcuts and remove my saved sites.

Hello Firefox Support Team,

I am facing an issue with Firefox Sync. I have logged in using the same Firefox account on my new device (or after reinstalling), but my bookmarks, saved passwords, and other synced data are not appearing.

I have tried signing in again, checked my internet connection, and confirmed that I am using the correct Firefox account. Despite this, nothing is syncing.

Please help me restore my synced data. I would really appreciate your support.

Thank you, Shubham Sen

I am using the Raindrop (raindrop.io) bookmark manager. It has been working fine on Firefox for years. However, with my recent update to Firefox 140, it is broken. Specifically, I can no longer use the highlighting function. It works fine on Chrome, but not on Firefox. I've seen several similar reports on Reddit's Firefox forum (r/firefox).

What to do? I don't want to have to switch to Chrome. Suggestions appreciated.

I've added pinned shortcuts to my homepage before, but am not able to do so now. I read the instructions, but am not seeing the three dot icon for the menu on my address bar. I have bookmarked the site and it is showing in bookmarks.

What am I doing wrong?
