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

I can access Chewy with Safari, but not with Firefox. So the problem is not with my Mac settings and the problem is not with Chewy, the problem is with Firefox. Please address and fix it.

Hi, Lately I haven't been able to add a bookmark icon on my 4-row new tab page. There's still to empty spots I would like to fill but can't find the usual + button. Thanks for the help

We had a power outage in our area. Afterwards when the power was back on I could no longer get CNBC.com to work properly. It kinda opens but nothing goes live nor do the videos play. If I switch to Chrome everything works, but I like Firefox! Lynn Nichols

Hi whenever I use my Google account to sign into websites (Google, ebay, YouTube, & anyother sites,) Firefox will become unresponsive, the window containing the tab i was using becomes unresponsive, sort of. - I can't click any open Firefox Tabs, - the red 'Close' radio button is greyed-out, so I can't close any tabs or the window - right-click is unresponsive, so i can't close tabs that way, but Command-W closes the tabs normally, but the others are still unresponsive.

- i can open a new Firefox window (with &/or without Tabs,) which works normally.

- & unrelated, but earlier, Firefox was running really slowly, Youtube videos were slowed down, but audio was normal, and scrolling was slow.

Hi there,

I'm wondering if I am experiencing intended behavior or if I've stumbled upon a bug. I am sometimes downloading files in a staggered manner (i.e., waiting for files to finish downloading before I start the next file downloads). However, any file after the first in that session shows an inaccurate progress indicator in the toolbar which includes progress of the already completed downloads.

For example, if I download two files completely, then start the download of two new files and both sit at 0%, the progress bar for the downloads actually shows 50% completed (2 files at 100%, 2 files at 0% -> Average of 4 files at 50%). I can't imagine this is intended behavior, for I imagine users would like to know how their current downloads are progressing only. This behavior is only fixed when I clear previous downloads, which resets the list to only active downloads, or when I restart the browser and start a new session.

Is there a setting where I can make the indicator report only active downloads?

Any insight is welcomed, thank you.

Good evening,

I'm going to install the applicatioin because it hasn't been working for several monnths ( it doesn't work anymore ). For exemple , if I want to watch Netflix and the video starts playing , there's no picture, it just loops and the screen is black.

I've tried everything turning off the computer, closing Netflix, even Youtube . I'm at a loss.

Thank you

After a recent firefox download, I noticed that on my 3 Mac computers, all using firefox on facebook, that none of my searches are being remembered anymore. But on Chrome they are remembered.

Does anyone else have this problem and what can be done about it. Facebook is useless for me without being able to use the search feature properly.
