When there is a field to fill in my credit card info, the info will appear and let me select the CC I want to use but when I move away from the field the CC info goes away.

Ever since the last Mozilla update several of my financial institutions or bill payment sites keep coming up with security certificates warning screen. Is this a known issue and will it be fixed?

How can I tell Firefox to automatically set the volume to 2 or 3, and not play every video in every window full blast - which is maddening when I'm using Facebook and every video I click BLASTS! the sound WAY, WAY louder than any other devices I have outputting sound, such as Spotify music.

Both the menu and the taskbar are not available since the latest update a few days ago. I've searched all options in Firefox settings with no luck in finding a solution. Help would be appreciated as this is extremely annoying and working around it wastes a whole lot of time.

After being able to view Netflix content on Firefox for, well, a long time, today I encountered audio with no video. Only a black screen. I contacted Netflix and they're telling me that Firefox needs updating - we tested Safari and it was able to play the entire content, video and audio. I checked Firefox and the info states the browser is up to date. I should add I'm on a Macbook Pro. The quality on Safari was not as good as Firefox has been so I would prefer not to have to use a second browser for one task. Can anyone provide some information on this situation?

Can log on to the Google Maps Web Site OK. However, trying to log on to my Google account (in Google Maps) I get the following message: "We've detected a problem with your cookie settings. ". If I try 'Private Browsing' in Firefox (CTRL-SHIFT-P) I am able to log in. However, this seems to have lost all of the Open tabs that I had in 'ordinary' Firefox.

Over the last 5 or 6 months, Firefox seems to have lost the capacity to remember my open tabs if my Mac is forced to restart. These open tabs are vital to my workflow. If this can't be solved, I shall have to migrate to another browser, which is something I do not wish to do.

My Firefox version is 147.0.4; my computer a Mac Studio 2025 M3 Ultra; my OS Tahoe 26.3.

Please advise.

I accidentally deleted all cookies in my browser using an extension and want to restore them to how they were one day ago, but I can't find the restore button anywhere. I found an article on https://support.mozilla.org/en-US/kb/firefox-backup , but I don't have the buttons mentioned in the article. I don't have a “Restore your data” section or a “Choose backup file” button, and when I click on the link about:restore, I get the response “Hmm. That address doesn't look right.”

PLEASE HELP

I have my browser.sessionstore.max_windows_undo in about:config set to 60 – it's been like this and working fine for several months.

It's set to this high number because I use an assistive technology which creates a fresh pop-up every time I deploy it, and Firefox treats it as a browser window closure when I close the pop-up. Consequently, I can easily rattle through well over 25 window closures in a day.

It's not necessarily that each window contains dozens of tabs and copious data, but nevertheless Firefox still treats it as a window 'within the meaning of the act'!

I just went to reopen one closed window from a couple days ago which did contain many tabs (partly why I closed it in the first place), only to find that the 'recently-closed windows' context menu is now only showing 20 windows (18 of which are the aforementioned pop-up assistive technology windows)

The really vital window that I want to reopen is not showing.

I've double checked in about: config and the browser.sessionstore.max_windows_undo is still set to 60 windows; nothing has been altered or reset.

I updated Firefox to 147.0.4 yesterday evening, but the problem existed before I updated Firefox, and is still in evidence since updating.

Two questions:

1) Why is the Recently Closed Windows context menu not showing the full number of windows it has been successfully doing with no problem now for months? I used to have to scroll down to access the full extent of the 60, but they were always there.

2) Why has it arbitrarily changed to 25 windows?

3) [I lied – Our chief weapons etc...] Is there a way that – given about:config still implies that the most recent 60 windows are retrievable – that I can access beyond the 25 windows limit that are currently showing as reopenable?

Thanks very much

(And yes, I already have things like OneTab and Tab Session Manager add-ons, but disabled those just before closing the important window, because I was trying to locate which add-on was draining the CPU. I assumed my 'recently-closed windows' buffer of 60 would suffice while I disabled the add-ons.)

Good day! Initially, I installed Firefox version (x64 ru) 147.0.3. After updating via the "Help - About Firefox - Update" menu, I received version 147.0.4. However, there are two entries about installed Firefox in the Windows section "Installed applications": 1. Mozilla Firefox (x64 ru) 147.0.3 and 2. Mozilla Firefox (x64 ru) 147.0.4. Although one instance of the program is installed. How do I remove an extra entry? Thank you.
